 Hello everyone. It's good to see you here. We're going to get started as promptly as possible because I want to give our Wonderful panelists as much time as possible. I Want to introduce myself my Joe Tiffany and I am the senior director of education for the Alliance to Save Energy I oversee our education programs, which are K-12 and College-level programs where we educate students about energy energy efficiency engage them in hands-on projects that save energy on their campuses and Also, influence the campus communities to save energy as well I'm honored truly honored to serve as moderator for this esteemed panel of energy efficiency Leaders who've achieved enormous success in making their universities more efficient and Who continue to work each day to make them still more efficient? I'm very excited to hear their presentations and I believe all of us will learn a great deal from them After they've presented, I'll invite you to ask questions and engage in what I hope will be a lively and enriching discussion About how to make universities models of energy efficiency in our country So if you think of questions as each presenter goes Jot down jot down your question if you wouldn't mind holding it to the end And then you can direct your questions to whomever makes sense to you Without further ado, let me introduce the panelists to you They have requested that I not give their bios to save time You will find their bios in your conference program. So please do take a look. They're quite impressive. I Will give names and titles however Starting out with Dirk van Olden who's the associate director of energy and utilities for the University of California system with the University office of the president Next to him is a Jared Isaacson whose energy analyst with the San Jose University Next to Jared is Joe Stagner Professional engineer and is executive director of sustainability and energy management Right here at Stanford University And last but certainly not least not forgetting you Joe is Joe And he is assistant vice president of the University of University of operations at Santa Clara University Please welcome the panelists and we'll get right started with Dirk Well Well, thank you, Joe. I have a couple of friendly people in the audience. So they're gonna If anything happens, they're gonna protect me as Joe said I'm there from all of the associate director for energy utilities in the office of the president Office of the president nobody knows where we are I guess we are in Oakland and it's essentially the business office for the university system I will go over some details. What I want to talk about today. It's not actually technologies But more the planning that goes into getting a university system like ours to Start reducing energy use and why you're doing that and just like the summit if you're attending today that takes quite a bit of planning But it can produce tremendous results if you do the planning right So as far as the University of California is concerned, we were actually driven by a few things We have a sustainability practices policy in place that dictates Certain energy reduction goals by certain dates The energy efficiency side is part of that, you know, Joe is gonna be talking about different subjects But I will just talk about energy efficiency for the University of California We have the goals that you can see on the slide here that after 2020 we'd like to become carbon neutral as soon as possible We believe that energy efficiency may contribute Maybe a third to that for the other two thirds. We have to worry about some other Initiatives, but energy efficiency also of course reduces our operating expenses the UC CSU and UC in the new spectrum all the time We're getting shorter and shorter or lesser and lesser contributions from the state to operate our university system So this really helps our budgets as well So how do you how do you actually do that? So we have you know, it's a large system You have to bring all these people in the students were actually the ones that started the whole process by saying wait a minute You know, this university is wasting a lot of energy We're not really green enough and we don't want to attend anymore You would think that everybody wants to be at UC, but apparently some people don't the faculty is also it's a newer generation They're looking for You know the pleasure they feel very comfortable with the environment and that we are responsible with those resources They have the staff that those are the people around our laboratories laboratories are very important part of our campus system They're very concerned about energy efficiency because they think we're going to turn the lights off and you know No more ventilation all that so that ruins their their experiments and all that so then security Other than that UC Davis most other campuses are very careful with that. They didn't want any light reduction Another big issue for them Then senior management. They said wait a minute. We can't afford this stuff because implementing this is very expensive So how do we go about that? Lastly as the Board of Regents, you know, they are appointed by And approved by the legislature mostly and then there's political connections there and there are a lot of pressure Hey, what's the university doing about energy efficiency and greenhouse gas reductions? So that's quite a tall worry you can imagine. So how do you do this while? reducing operating expenses, so we we have an answer It's very costly you can imagine How do you do that? Just to give you a brief overview of what the university is all about. It's currently a 21 billion dollar enterprise, which is If you look at corporations in California, and we're we're right up there We're larger than for instance PG&E or Southern California Edison. You're also not a state agency. We're a we're charged by California Constitution and we call ourselves the fourth branch of government What helps is sometimes it hurts sometimes so we have ten campuses and five medical centers And about 50 fuel stations that are agricultural people the utility bills about 250 million dollars a year We consume about 1.8 billion kilowatt hours, and all is in place. I believe it's gonna be on the website So may not need to take all notes here And 140 million therms per year that's mostly used actually in our cogeneration facilities And as I mentioned a little asterisk here regenerate about 30% of our own energy the different campuses 120 million square feet of space Over 5,000 buildings all over the state and a lot of these buildings are more than 100 years old So you can imagine what challenges we have there Campuses also at least I'll tell you that They're autonomous so the chancellors that kind of run their own show so we cannot really dictate anything from the Office of the president, so we have to do everything through persuasion and leveraging and blackmailing whatever it takes Then a medical centers a year about them. That's say UCSF in our case. That's nearest They're not state supported at all. Those are actually major profit centers for the university system So we developed a plan started in 2007. I was actually hired for that by the university And we got them from our angel investor, which was and run in the settlement that we that was reached Costs 1.7 million dollars to come through all the campus and medical centers and look for projects Then we started leveraging all these different people that we needed to bring on board and that's where the term partnership comes from And that's the various utilities in the state investor owned utilities It's Edison down south PG&E the gas company down there and then send the a gas to an electric We brought in facility management because these are the people have to implement all the projects the budget officers They are the ones that have to approve the project if they're you know, make sure they're financially feasible Our chief financial officer staff they had to go out there to the bond market to eventually finance these projects And then the State Department of Finance even though the state only contributes something like 5% to our budget this point They're still keeping an eye on how we spend our money. So that's kind of a sore issue, but that's what we're dealing with This is this is essentially layout of our campuses and how the utilities are serving us and Utilities are actually our major partners in this particular endeavor So we published the strategic energy plan 2009 we had identified at that point 950 million dollars worth of projects the campuses then they went through with the fine-tooth comb most of the budget officers Make sure that they made sense and they came up to $247 million dollars worth in in a cycle that would span from 2009 through 2012 no 11 excuse me three years and Then overall the payback would have to meet that requirement and I've shown here When we back went back to the regions that is what we have these campuses will do they authorized 178 million dollars in external financing which is bond revenue bonds The utilities by then they had seen our project list and they said you know what we'll kick in up to 61 million dollars That's all four of them and then the campuses said we have a couple of bucks. Also, so they get in here Implementation itself is done through the utilities. It's our partnership program which actually provides for a third-party Review system which was required by the bottom the writers that you know Just stick our word for it. They said no no we need some third-party people And that's mostly M core and Arab just other engineering companies in this area So we were we had to go to the state and I'm all worried with this too much But there are some very tricky points. We have to go through the the legislature actually get this authorized So there's a certain provision in the budget acts and there's one being signed here shortly That seems to be recurring here after you that's just for the University of California where we can actually use operating funds for paying for capital projects, so that's a special deal here Then we have internal requirements so we want to make sure that on the portfolio base to take all the projects together that the debt service on The bonds that we are going to issue that do not exceed 85 percent of the avoided energy costs That's a very important criterion and then we issue these bonds for 15 years of prevailing rate Which is little under 4% currently your tax refunds So begin 2009 Starting that date we couldn't get the contract signed by the facilities right away But you know somewhere around May or June we started in 2009 We have done about 130 million dollars worth of bond finance projects As you can see we we have 600 some projects underway or completed We are saving about 10% of our total system use only electricity about 8% of the gas use and then $30 million in avoided utility spent so that is before that service And the utilities as far as I can tell from our records have either paid or will be paying a committed to about $51 million in incentive so far But I'm not showing here is we have probably created thousands of green jobs in the process all these engineers and contractors and have worked on these things So we haven't mentioned that too much of their time you see the governor we do mention to start my green jobs, so So we're counting on this program going forward 2013-14 we are already in discussions of course with the utilities We've talked with the PUC about this and we're talking to Sacramento. Just make sure the funding will be available So this is where we are. We'd like to go to some deeper savings. We'll talk about technologies today, but it's Pretty impressive what we have done so far So I just want to let you know it takes a lot of planning takes a lot of people But if you get them all to dance together, then we can really produce some results. Thank you I got my a lot of contact information here and again this will be in the website You can see all this stuff our strategic energy plans for each campus each medical center their own this website We have a working smarter program, which means we are we have committed to reducing our operating expense by four hundred million dollars per year This this is a big part of that obviously and then there's some other stuff there in my contact information. You have any questions. Thank you Okay Jared Isaacson I'm Jared Isaacson energy analyst at San Jose State University So the content of this power point is going to be a little bit of background on the university Some information on our central utility systems as well as energy efficiency projects a little more specifics and kindness project case studies But a lot of it has the background that dirt mentioned about how planning and implementation is Is run So some campus facts SJSU is part of the California State University system It's the oldest of the CSU campuses. It has been at its current site since the late 1800s It has buildings ranging from 1910 to 2005 And some under construction now the average building age is 40 years old So that presents some challenges. It's aging infrastructure some issues with maintaining facilities We have two sites the main campus where all the academic administration buildings are and the south campus Which is primarily athletics. That's where Spartans stadium is located and SJSU is one of only a handful of those 23 state CSU campuses. It does have a cogen The campus overall main campus Day their farm from nine megawatts and the cogen units name plate capacity is six megawatts So some of the framework for our energy policy is CSU executive order of nine eight seven it incorporates a lot of the state mandates But its policy focuses on energy conservation Independence Promoting on-site generation as well as renewable energy So in terms of the system that we have in San Jose state We have our source energy This energy that's fed to the central plant and then what's distributed to the campus buildings the cogen's Combining power uses natural gas as a fuel and it generates about two thirds of the annual campus requirement And that's in terms of KWH not KW and steam production Distributed generation so one of the things I like to say like to promote cogen is that having the on-site generation Avoid some of the line losses and Transformer losses from transmission level power from just merchant plants in the valley where they're located To urban centers like the Bay Area. So cogen is also highly efficient I'm gonna get into a little more detail about our unit in particular So here's a picture of the engine It's a now it's a Rolls-Royce in condition. It was an Allison 501 KH engine Modified for stationary combustion, but these are aircraft type of engines So we've got the turbine the heat recovery scheme generator, which is not pictured. It's kind of behind that This is when they were moving the engine And this is really what's the main part of this chain cycle of patent technology Cogen that we operate where we have injection steam which not only increases the power and Efficiency, but it also lowers our emissions in terms of not socks and carbon monoxide and Processed steam generated by the unit is used for campus Steam loop for building heating as well as heating hot water as well as absorption choice I wouldn't call this silly our system try generation, but it could be You know configured in such a way it's try generation Okay, so about our cogen we had a consultant report and We're happy that findings were that the net present value of the existing cogen is $15 million over it's expected to light for about 10 to 12 years And that's even including greenhouse gas to cost associated with 8032 and we expect to start having to participate in All we know we're going to participate in air resources towards cap and trade system. We're over 25,000 metric ton threshold for about 30,000 and So that says to me 6.7 million over the next eight years. That's the best data We had we have some estimates going out the light of the cogen, but it's kind of up in the air right now This is it's very How is this going to impact our our campus? Yeah, we don't we don't entirely know But Nevertheless the new equipment plant if we were to scratch this one out of part of those consultant report and install the new one We still have a return around 14% is very attractive and something we're looking for in terms of cutting costs and that's a IRR is a Corporate metric but in terms of us in terms of state agencies it's cost avoidance. You call it So then electricity we actually have a high voltage electricity connection with PG&E 115 kV we're at a 20 transmission level rate and We operate our own substation that supplements the cogen's power. We have a standby group of PG&E case the cogen goes down Maintenance and whatnot and even during peak summer days where we're importing and we operate our own 12 kV distribution system So energy consumption I kind of mentioned before get natural gas I want to electricity. That's what we're basing our carbon footprint on that tier one emissions Then from energy management standpoint, but we're also considering the outputs electricity steam and therms chill water in Ton hours and we pay those to BTUs in terms of energy intensity units And that's really more how we gauge our success in building energy efficiency And we've we've done a lot. This is BTUs per square foot. You can see Five so it's more like seven years ago now over 120,000 square foot. We had a big Drop because we had a lot of low hanging fruit In our initial program with the utilities where we received the funding and we're working on it But it's it's more difficult. We've done a lot of the easy fixes and now we're trying to get into deeper savings Okay, just to what alright, so we'll run through this then the partnership UCCS UIU Universities investor in utilities to date. We've received three million dollars in incentive funding in San Jose state That's really aided our efforts quite a bit Demand side management over that period nine million kilowatt hours saved two hundred thousand terms 1.6 million in utility costs and that's around 15% of our carbon footprint when we we started at a low cost it's avoided consumption rather than new generation So here's a good project one of our case studies. We've got a best practice award from a university higher education sustainability conference So library it's a joint library at the city. We had a monitoring based commissioning project Which is a continuous commissioning type of project identified a lot It's fine tuning of a building that was really only three years old But it gave us some money to do that the lighting retrofit those was really big 20s to 25% energy reduction big demand reduction as well 5000k lighting occupancy sensors on the book stacks. It's a it's a very large library nine stories five hundred thousand square foot So it did a lot Big savings you guys can check out on the PowerPoint if you want to read more into it So you can see the first three years the first two blue and the purple really high monthly energy over 500,000 kwh per month The yellow line is when those projects really started coming online and then after that you can see Big avoidance there big big savings So lead building was lead certified in January those energy efficiency projects really Contributed that energy performance. We got actually got a pre-exempted performance credit and materials and resources through toxic materials reduction in lowering our mercury perlumen Some other things we're using recycle water the dual plumb building or toilet flushing as well as for all the landscape irrigation outside daylight is big take a look at that You can see all the windows and then the last project here's a current project Chiller replacement, so we've got five chillers in our plant to electric centrifugal to steam absorption and one combination centrifugal ice maker and TES associated with that We replaced the old chillers probably a 20 year old chillers increased capacity for new load not necessarily like ton hours overall BT's but but Increased peak cooling man, and then much greater efficiency of the VFD's Your refrigerant more environmentally friendly Here's those chillers they're York machines This is a big deal 3.7 million kilowatt hours and two hundred ninety thousand to save Therms save mainly because of how we're staging the sequence of operation with our absorptions big incentive we're really happy about that project and what What this really did for us this incentive funding it really improved the scope of this project We initially were talking about increasing capacity for cooling through adding another cooling tower wasn't going to increase efficiency So we're happy that the funding that we got really helped us have a more energy efficient solution than we were initially planning in the scope Really quick some challenges budget constraints huge time constraints resources Projects are disruptive and they're inconvenient to the occupants. So it's it's a problem and we'll Start at the beginning so the end So thanks as as Dirk and Jared mentioned there's two big areas For university energy efficiency reducing greenhouse gas and the first is course managing your demand So building very efficient buildings and then retrofitting your existing fleet So we we recognize that and we have any number of programs For doing that on Stanford from the night school of management lead platinum to the new science engineering quad very efficient And what we call the whole building energy retrofit program They've done a lot what I'm here to talk about today is our energy supply side though I agree with Dirk that that the majority of the opportunity to reduce the environmental impact and improve the cost Efficiency of long-term energy supply for university is going to be in how you produce and deliver the energy to the buildings Even though you've gotten the buildings very efficient. So We've just culminated a three-year planning effort on what our next long-term energy supply plan for Stanford will be And it's resulted in Basically a half billion dollar transformation of Stanford's energy system that we call the Stanford energy system innovations project And so I'd like to tell you a little bit more about that First a quick overview of our existing system We have a 50 megawatt combined cycle cogeneration plant that serves standards heating and cooling needs and power needs since about 1987 The current contract for that It's a third-party owned general electric plant and Stanford contracts for energy services from it that plant's going to be about 28 years old in 2015 when the current contract expires And so we've set about deciding what the successor strategy for that would be whether to build a new co-gen or do something different Overall that plants about 53% efficient Today's co-gens are in the 60s typically I think San Diego's down the mid 60s and San Jose and others are but you can expect to get high 50s through You know even the high 60s depending on exactly how you're using the thing But it is our basic big energy supply. So it counts for 85% of our greenhouse gases and Some people don't know it uses one fourth of our entire fresh water supply all those cooling towers that are used for Rejecting heat waste heat both from the co-gen and from the chill water system consume quite a bit of water You can probably see big plumes of condensate. You know when you go by a university that has a co-gen plant on a cold morning That's all heat and water going to the atmosphere And of course the co-gen plant delivers those services to the buildings The underground cables and pipelines so you've got your electrical cables going out to power the buildings You have chilled water that that's circulated around to cool the buildings and you have in our case steam That's sent around the buildings for heating now all of those Systems lose energy along the way line losses and steam particularly loses a lot of energy We have a very well maintained steam system by a lot of standards But we still lose 14% of the energy from the central plant to the buildings many universities and municipalities are well over 20% in the loss of that you think of the old manholes and Manhattan and steam coming out. That's what it's from It's loss of energy And it also costs quite a bit to maintain our steam system We spend over two million dollars a year because there's a lot of mechanical devices steam traps and pressure reduction valves and stations and so forth So when we looked at the successor strategy for our current energy system We of course realize that the campus is growing. So whatever we put in has to be able to be expandable We knew that we wanted something economic and energy is very expensive There's been a lot of volatility especially in gas prices in the last decade Maybe that'll settle down for a while with this gas fracking and these new supplies But we've all been brutalized in in the first decade of the century by the volatility in gas price and Water's going up, you know just the water supply for the barrier those prices are going up significantly as they Have to retrofit the Hetch Hetchy system that brings most of the barriers water from the Sierra Nevada Mountains all the across the valley And of course sustainability we wanted our new energy system to really Look at all the available options give us the maximum flexibility to adopt Technology change over time to make things cleaner and more efficient And so what we came up with we call the Sanford energy systems innovations system and it will take us to about 2050 or beyond really So the core of this system you could think of as another form of cogen I'll call it the new form of cogen for us and it's combined heating and cooling not combined heating and power When you think of a chill water system, it's really just a system for collecting heat from buildings You're not delivering cold. You're really just collecting heat heat the buildings don't want You're collecting all that heat taking it back to a central plant and you're spending electricity and water to exhaust it to the atmosphere via cooling towers So we took a look at hour by hour at Stanford How much heat are we collecting currently and exhausting out cooling towers? And in that same hour how much heat are we sending out to the buildings via steam and on the left you can see a chart Which is a typical summer days chart You can see it's the 24 hours on the bottom and the amount of energy up the y-axis and So you can see what you might predict that you know night It's cool here and in the day it gets warmer and we have a lot of heat to reject So that blue line shows how that cooling demand goes up in the day and then goes back down at night And we get these cool cool day evenings We also have a fairly constant demand for heat a lot of people don't know how complex research buildings and in office buildings work But when you have a big building with many different rooms and activities going on they want to be at different temperatures computer server rooms want to be cooler than Classrooms that want to be different than office rooms and so forth So buildings have what's called a building reheat or zone reheat system Where if you make temperatures that are say 66 degrees at the main place where the cool air comes in the building And then you send it through ducks through all out the rooms Well some rooms might want to be 68 some rooms might want to be 72 degrees right when you change that thermostat So the way that's done is through little heat coils in the ceiling where the cold air comes through and you heat it back up a Little so if you got 66 degree air going into one space in another space That same 66 degree air has to be cooled by little coils right above the ceiling called zone reheat coils To make it say 72 degrees for this room. Well, that's heat that that's basically hot water flowing through those coils that then Has to be produced and delivered to the building in the first place So that's how there's in many complex universities a constant amount of both simultaneous heating and cooling So in our case when we mapped that out for the whole year and looked at it We said look at that green thermal overlap, you know, that's how much energy were low-grade heat Basically, we're collecting and wasting and that's how much at the same time low-grade heat We're making with fossil fuel and then delivering. Why don't we see if we can use that heat Instead of producing it with fossil fuel. So let's see if we can reclaim that heat When you look at it for the whole course of a year, you see the chart on the right The top part of the y-axis is our cooling demands and this course in summer You can see with the blue that we have more cooling demands and in winter we have more heating demands But there's quite a bit of overlap So the heat recovery potential you see there is that over the course of the whole year We found that 70% of the waste heat we were collecting and currently wasting and discharging out cooling towers We could actually repackage that as hot water and deliver it to the buildings And it would meet 80% of our annual heating demands. It's quite substantial And so we set about Examining that system and whether it be cost-effective to do it so We looked at nine basic options all the way from brand new gas-fired cogeneration plants based on gas and steam turbines to the new internal combustion engines two combinations of cogeneration and heat recovery to a hundred percent heat recovery plant and The one you see a circle there is the one that the university selected and it's the one we've started building And it's basically an option to move from being a hundred percent natural gas-dependent campus for energy to being almost a hundred percent Electricity dependent so we're going from gas to electricity almost like your car might go from gas to electricity in the future And that's because electricity is a source. It's diversified. It's partly based on fossil fuel But it's partly based on renewables and nuclear and other things and that Electricity will get greener over time. We know it has to be 33% green by 2020 so in our long-term strategy not only was moving from gas to electricity and from Cogen to combine heat and cooling overall more energy efficient and more economical We believe it represents the best long-term path to be able to eventually move to full sustainability of our campus Once we can work on getting those electricity supplies more sustainable and green if we had bought a new cogeneration plant We would be basically tied to gas again for the next 30 years and wouldn't have a lot of opportunity to adopt new technologies and clean up our portfolio So the benefits of moving to this electric heat recovery plant We're using a lot of free heat we're saving money and our operations and maintenance of our steam system by converting to hot water And we're reducing line losses And we have some very significant environmental impacts So we will cut our greenhouse gas emissions are real actual category one and two greenhouse gas emissions by over half When this plant comes online, it's primarily by more efficient equipment and reusing waste so we'll be well ahead of California's goals and and in a real good position to move to a hundred percent sustainability as we and or the grid clean up electricity supply We'll save a lot of water. I mentioned the existing plant uses 25 percent of Stanford's fresh water By not using wet cooling towers to exhaust all that heat into the atmosphere We're saving that water with heat recovery. You're not wasting that water You just taking the heat moving it from one fluid stream to the next so we'll reduce our campus water use immediately by 20 percent There's a few other collateral benefits of getting away from steam. It's hot water is much safer system for a university We'll have high pressure steam around. Thank goodness We have had the accidents and they're not common and they're not a reason to not have a steam system But it is a collateral benefit To do this we have to weigh in a whole new hot water system for the campus So rather than convert all our steam pipes We're using a European shallow buried system where we can lay in a new hot water network to supply our buildings. I won't go over this but it's in the Documents for those of you want to see the configuration of the new system This shows a picture of the new plant which would be located on the west side of campus It involves both significant hot water thermal storage as well as cold water thermal storage and the heart of the plant will be three 2,500 ton heat recovery chillers also by your Jared mentioned This shows the configuration of plant the hot cold water storage The main heat recovery plant and then the minor conventional boiler and chiller plant, which is our backup for our Oshpa hospital Again, 450 million dollar project about half of it is converting our pipes and about 40% the new power plant and the new electrical substation We're also looking at foldable take power now removing to be an all-electric campus We're looking at significant on-site foldable take we should have an RFP out For a substantial amount of that soon and will it looks cost-effective. We might be able to proceed with some of that and lastly to take care of some of this Heat rejection and summer that we can't use heat recovery for and for making heat and winter rather than burning gas and boilers We're looking at ground-source heat exchange So you have these great machines that can extract heat from water and turn it into hot water Why not go ahead and suck some of that heat out of the ground and winter and make heat with that instead of fossil fuel Instead of using water and summer to reject the heat why not then put it back in the ground For more information, we have a Stanford Sustainability website will tell you a whole bunch more about this as well as our ongoing efforts on the building site. Thanks Well, I had two goals for today one was not fall off the stage The other one was get over here with that tripping off the stage, so we're good to go. It's all gravy from here on out Santa Clara University is about 30 miles south of here We're small Jesuit University of about 5,000 undergraduate students and 4,000 graduate students We live under the shadow of Stanford But we tell our we tell our students that we tell our potential students that The people who go to Stanford are the ones who can't get into Santa Clara Smart microgrid is my subject today. I'm not going to talk about details of our energy saving SCU dot edu slash sustainability has a great wealth of information about our sustainability initiatives Among them energy conservation and energy savings and greenhouse gas reductions, but I'm going to talk about one specific Item today the smart microgrid About six years ago when we were developing our 20-year strategy a number of things happened that kind of influenced our thinking One was one we called the El Paso gate issue Which for some reason or another that we don't know Immediately double the price of our gas Without any warning and with no parent operational reason The second one is something that you all in California come to know in love the rolling blackouts the third one was the hurricane that hit New Orleans and flooded the city and The students at Loyola, New Orleans and other Jesuit school had to vacate this campus was closed for six months Many of those students came to Santa Clara University. They did not return to Loyola Miramar. They stayed and graduated at Santa Clara So these all went into our thinking about the energy strategy and we Commissioned a firm from LA Susca, Hennessey to help us look at a zillion alternatives For how we want to proceed over the next 20 years and All of the things that we came up with centered around one important aspect and that was developing a smart microgrid for the campus Now there's a lot of a lot of different versions of a smart microgrid So I'll tell you what we mean by ours. First of all, it's a close to electrical grid like both Stanford and San Jose State have It can operate independent of the grid or it can operate in parallel or connected to the grid And it includes the campus load some distributed generation is important on campus it has some energy storage capacity it has the The single point of utility grid connect and the thing that makes it smart is the intelligent cross control system We Don't particularly want to be energy to independent all of the time But we do want to be able to keep our classrooms open So we have to have a system that controls where our electrons go a particular time of day And that's the key to our smart grid system Okay, why do we want that these are a number of reasons that we think is really important I Believe Joe used the term it For most our sustainability goals will use a different term called environmental justice But it solidifies our foundation for environmental justice at Santa Clara University It helps us manage our resources It gives us a living laboratory and we have a living laboratory at Santa Clara right now We're a number of people both on campus and off campus come and try out new things In the developmental stage the microgrid gives us another tool for that that development both For students for faculty and for other industry in and out of Silicon Valley We of course want to improve our liability reduce cost manage our demand Part of our distributed generation all of it one day should be clean energy Generation and we see the microgrid is as a key component in being able to meet our Goal of being carbon neutral by 2016 Finally based on the Katrina Lessons learned we need to keep our classes open 80% of our revenue comes from student tuition So we can't stand a long energy outage We need to be able to have enough electricity on campus and have energy on campus to keep our classrooms operating for extended periods of time should we have a major disaster and That that informs us in terms of how much how much distributed generation we need But generally about 60% of our of our peak demand is what we need on campus. That turns out to be about three megawatts That's what we want to do. Let me tell you where we are so far. This is our campus It's 105 acres. It has about 55 of smart buildings now all of them can be controlled centrally from one location We have a 1.2 megawatts of distributed diesel and we have a single Interconnect with Silicon Valley power. We have a megawatt of solar generation in place that produces about 9% of our total energy, but reduces our peak demand by about 15% We have another 50 kilowatts of solar on our building That was our test case and we have a campus energy management system that controls as I say where the electrons go and In development one megawatt Biofuel generation plant That will use primarily food waste. This is fuel source and One megawatt co-generation plant that meets our limited heat load capacity heat load needs for the campus Thank you very much. I'm open for question Dirk was allowed allowed on this panel even though his name does not start with a J Jared was allowed even though he doesn't have the name Joe Thank you very much I want to throw the floor open for the remaining time to you folks to after ask your questions And if you would stand and speak loudly that would help We're each of the slides on the pre-court website or their individual My understanding is that the slides will be put on the pre-court Website after the conference following the conference I really pleased to hear this from the University perspective and Joe you just touched upon the relationship of the students and the faculty I've been involved sometimes in programs with Universities where there was quite a separation there and I was just curious if any of you would comment about from the facilities perspective or operation perspective How you go about reaching out to the faculty and the students to get an exchange going where they Actually learned by doing Well, I'll take the first step at it University operations has has as part of his portfolio of grounds custodial campus safety parking facilities In 2006 we started the sustainability program at our 2004 we started the sustainability program at our campus and hired the first sustainability coordinator That person is now the director of the office of sustainability It's always reported to me, but it's always been housed or The desk is always the offices have always been in the environmental studies Institute, which is an academic institution The faculty do not know that The sustainability officer is part of operations. I think it's part of the faculty. So the faculty is very open To communications with the sustainability office, but that doesn't sound like a huge deal, but it really is as a result This the students then have a much easier time Communicating with the sustainability office and she directs it down to us when they're looking at Okay, I want to do a project on energy needs or what what are we doing on campus or how can I incorporate? Energy saving devices into my academic curriculum course then then that ends up back on my desk But that's the way to get it there They would never walk across campus that come into the facilities building to talk to me So it's kind of a trick Now we have a little bit of credibility in it's better off Here at Stanford we have a number of ways we have what's called a sustainability working group that has representatives from both undergraduate and graduate student sustainability organizations We have sustainability working teams. So when we sat about Reinventing our master plans for each of our services water energy transportation waste and so forth We established sustainability working teams and invited faculty with that subject matter expertise or interest as well as students To participate in helping to develop those long-range plans Out of our office of sustainability, which is also out of our facilities group here my department as it were We also set up a green fund where we make thirty thousand dollars available every year for students to do projects related to exploring or Administrating on campus here energy efficiency and alternative technologies So we have any number of contacts and same with professors We've had several committees and any number of peer reviews all along the way of our planning for these energy supplies and master plans To have all the faculty with interest and subject matter expertise there to help us make sure that we Have all the information we can and making these decisions So at San Jose State, we have one of the problems that Joe Sugg alluded to is that we're seeing as separate from the faculty We're part of the facilities group. So black credibility one of the ways we we are hoping to bridge that and kind of Bring together some of the goals that we have is we worked on this this audit a sustainability audit through a she's got the American Society for sustainability in higher education We did the stars sustainability tracking audit and it had three components that had operations mainly the facilities and transportation and such and curriculum and kind of engagement and how sustainable is is the foundation and University engagement. So that was really the best way we had to bridge the gap to get people at the same table So for the University of California, that's kind of all over the map There's a massive program that has been organized by Joe's organization, which is the green campus program Which nurtures a lot of students think in that direction. That's most it's not all that technical at this point But many of the people that were involved in these programs are actually hired upon graduation either within the university system Or by the utilities for instance and other energy service companies Our I've been with university about five years It's always frustrated me too when I hear the comments you're making that there's very little interaction between our facility management people and the faculty so Many many of our campus of Berkeley is a good example They have that just started their own program and they kind of inform facility management Hey, we want to do this but they get their own grants and they want to test their own technologies And then we support it kind of in a reactive mode We'd like to see much more of that there are interns by the way that are Mostly in grad school actually that want to work with the office of the president because I think we are you're we are smarter We're not that's what they think And and then we can deploy some of those ideas to to the campuses, but there's a there's a long way to go I agree with you We have a lot of engineering students in our system that could make quite a contribution and of course many of them Do but you know after they've started their companies are coming back and trying to sell it You tell him I don't know. I don't know. The George Cominth We should cut you his technologies have potential for universities Can you have a very any example of that like are about He's starting in the ground with his health the other example and what is the potential for savings The University life scale in the college Sure. Of course we get approached all the time on that. The biggest technologies for us speaking on the supply side were of course efficient central plant equipment. A lot of gains have been made in conventional equipment like heat producing boilers and chillers. We were really having a tough time finding heat pumps or large industrial heat recovery chillers. Only one or two companies in the world making them. Fortunately we found most companies and their efficient enough machines to make our scheme work. We hope to see a lot more advance there. The other big area we found was that the technology for operating a central plant with any number of pieces of equipment, co-generation boilers and chillers, juggling all that and doing it the most efficient way possible, right now operators those plants, they're just using their best guesses. There's a few optimization softwares that will look at a particular point in time and say right now for these loads run the equipment this way. We actually knew that using thermal storage we wanted to look ahead constantly a week at what the weather and loads might be and have software that instructed our central plant how to operate most efficiently mathematically by knowing when to produce and when to store and when to take from storage and so forth. So we couldn't find any software. We actually have invented it pat did a startup company has licensed that technology from Stanford and then take to the industry so you can put in these really forward-looking optimization programs and run these plants far more efficiently. We see a 5 to 30% efficiency gain just in allowing computer automation of these complex energy systems to run rather than relying on people to do it manually. So those are the big areas we were interested in. Really quick follow up to that point. For our new chiller plant part of the big controls retrofit piece of it is we're using an adaptive predictive software technology for controls and it's through a GE intelligent platform. And just briefly we have we have this all the time people knocking our door so you know I'm a UC Davis graduate whatever and I think we have the right to install our equipment but they're actually some very brilliant moves and I'd like to echo what Joe was saying we were implementing something like that at our San Diego campus which is very very advanced so advanced that they didn't even understand it they had to bring some other people in to integrate it but we are definitely looking at you know keeping the human element out of this as much as possible. These operations are on the campus are very very complex. This is a very good presentation and I think it's a very good job. We appreciate that. Our current energy contract with Kernel Cogen we're averaging about eight cents kilowatt hour. It's tied to the PG&E tariff by contract for us. Yeah it depends who you talk to on the campuses sometimes to try to suppress some of the other costs associated with that service and operating costs. Our San Diego people are they claim it's about six and a half cents. I think it's more in line with what Joe is saying overall in our system is probably about eight. But that's just the electricity the benefit of course that we do not crank in there as a discount for the heat that it generates and that has another benefit. Yeah. They're not really estimate stuff part I mentioned earlier that all of our projects are bedded by the utilities. The third part is they're doing all of the measurement and we post all of that in a in a what we call p6 database. Not all of it is port meter but everything that's MVCX related that's the one that Jared is also talking about that's actually meter data we keep track of that. Regular benefit projects are mostly estimates when the project starts but when they're completed again the third party they verify that because our incentive based on that. So we're pretty accurate on that and actually right now on a system-wide basis our debt service is about sixty five percent actually of the mortgage costs. So we're our campuses are delivering on a much lower cost we have thought. Yes. All right. We currently have steam distribution to serve the whole campus. We're abandoning that place and replacing it with a hot water distribution. So for the new heat recovery plan we'll be sending out hot water about 160 to 170 degrees to eat the buildings. There's a few places where you still need steam for process like for sterilization. We'll have a very small unmanned automated boiler and bioscience area of campus that will supply very few steam needs. We estimate steam for process of less than two percent of the total heat demand of campus and so that's why having a steam system for the whole campus just to support the very process needs is not necessary. Well the existing steam piping we're keeping the little pieces of it in place that we need to to get just the process steam out in that local health sciences area. It's an entirely new hot water piping system we're installing. You'll see the right in front of our main quad trenches open today as we start to move into phase two of our construction. This whole area of campus including this building is already on hot water. $100 an hour.
