 Well, hello everybody. I'm here to moderate the last panel. I'm Scott Sklar And I have a company that blends all these clean energy technologies together. So I love this panel. I also have two Buildings in Arlington, Virginia that are totally off the grid Which I give tours to blocks from the Clarenin Metro stop and With a blend of a lot of the technologies that are going to be talked about today I want to say that it is I've done a hundred and twenty seven Zero energy buildings meaning they use no energy from the grid All over the world most of them not dinky ones like I haven't already did a two stories But to eight to twenty five stories and it is able to be done the technologies Exists the companies exist It is really creating Local will and standards to to drive into that direction. So we have a great panel and the the approach of our panel just to remind the panelists are about five minutes because I really want to get to some Q&A and So Katrin Klingenberg co-founder executive director of the passive house Institute us acronym Fias PHI us is our first speaker that I pronounce that correctly Whoo, you got it. It could be fias. All right. Sorry. I think you're on I would speak a little louder though Just to give it a little zip Yeah Is there like a little light Now it's on haha, here we go Technology so good All right great So thank you for being here with us last panel of the day. Hopefully it's going to be a good one Passive building has been my main focus for last whatever 15 years almost now and I'm still with it. That's a Passion Scott like you I can point to as many buildings But I totally agree that the passive building technology has come long ways It's not a new thing has been around for quite a while but I'm happy to report that We are now really zooming in on really great tools really great components that make Passive buildings really possible on a mass scale and that's what we are working on. We are 501c3 non-profit organization our main focus and mission is to make passive building mainstream and when we were Founded our goal was by 2020 so I guess we have to kind of hurry up a little bit Right now the trend looks really really good We have now certified and pre-certified passive buildings. We do certifications quality assurance for past buildings we have crossed the 1 million square footmark in the United States and What if you count all the projects into that that have been? Kind of submitted to us then we already at like 2.5 million in this country So what what what is this thing the passive building? Concept or what distinguishes it? It's really not rocket science We have as far as I'm concerned no technology challenges left any more in my fabulous panel here All the components that we need to make these ultra low load buildings possible. We have them There are really five main principles that constitute a passive building. You need a really good envelope shell in terms of installation You need a really good airtight layer so that you don't lose energy through leaks and that also your building envelope is durable You don't have any moisture problems. You need really really good window and door components and Once we built the building really airtight You also need a heat recovery energy Ventilator so that when you ventilator building you're not just throwing the energy out the door that you've just generated Sometimes with force our fuels and then last but not least if you do it all right Then you only have to have a very very tiny mechanical system like we used to joke like you can heat your hair Your house with a hairdryer. Basically, that's the idea. You essentially almost eliminate the Mechanical system that is still needed to keep your house comfortable So how is the passive house Institute helping to facilitate that we just recently got into the standard-setting business We developed climate specific passive building standards for all the varying climates in the United States and The purpose of that one is so anybody can build a zero-energy home, right? Like so where where can we help? We help with these design guidelines that guide the designer towards the cost-optimized Point between conservation of the envelope and then where do you start with your renewables and that's exactly what these standards do for the designer Buildings built to the passive building standard save approximately 70% overall energy and that of course translates into the equivalent carbon Savings and once you build your shell to these very energy efficient standards than only very tiny Renewable system is necessary to take you to zero energy or even further to source zero and that's really where we should be So nation-wide we have seen quite a bit of incentive and policy Progress the affordable housing sector has been especially interested in the passive building principle because of course when they own the buildings they retain the savings and So we have seen in the last couple years two years actually Really the hockey stick in terms of certifications from the affordable housing sector driven by them And that's a very exciting development to see so nationwide I would say we're set up to really make this ago we need political will now to take this to mainstream and But that I think we have a fabulous panel here Folks who can help to make this happen in a very cost-effective way. Thank you Catherine Our next speaker. That's good We have Paul Bertram from Kingspan Kingspan's interesting company because it's a blended technology Deliverer so they have Building envelope they have a solar and Electricity and daylighting they have LED so it's a multi technology provider So I'm glad Paul you're you're willing to come today and be at our panel. Take it over. Okay. Thanks Scott Yeah, as you say We're multi Portfolio based for all energy efficiency one thing wasn't mentioned as we do under air floor systems for data centers So we really cover a wide gamut of Energy efficient solutions for both new construction and retrofit. We're headquartered here in North America and Florida and the Daytona Beach area and We have operations in Canada US and Mexico that basically I do environment sustainability and government affairs for So AC triple E has some data out that says that it would cost 3.5 cents a kilowatt hour saved to implement and a successful energy efficiency program and They go on to say that that's a whole lot cheaper than building new power plants So what they're really telling us is that energy efficiency is is a really big missed opportunity and clear back in 2007 the McKinsey Quarterly report called the cost curve for greenhouse gas reduction showed that building insulation was one of the most cost-efficient ways That we could reduce demand side energy with greenhouse gases So one of the things that I believe is really missing out of the whole picture is a focus on on below first and Take this statistic there are approximately five million commercial buildings comprising 70 billion square feet in the United States of which Approximately 60 to 70 percent were built prior to 1980 Or the market release of low e-glass and we have another panelist that will speak that out a bit So over 50 percent of the building's interior loads are impacted by how the envelope performs. So we're seeing an awful lot of Interest in and the interiors I'll speak to that in just a second But we're not seeing enough attention to the envelope and part of that is because of the long-term paybacks compared to things like lighting and Heating and cooling so that is one of the policy areas that is going to have to be addressed. How do we how do we look for longer-term? Incentive programs how however that might shape out But the energy efficiency sectors really providing effective Results in reducing demand side energy, but you're hearing again with LEDs improved HVAC systems and building controls And there's some recent surveys out there. EIA just released some data from the commercial building energy consumption survey and found that consumption had been reduced about 12% this was based on 2012 data and again lighting and space heating were the biggest resources of Reduction and Johnson controls just had their energy efficiency of Program a few weeks ago and their survey is finding that there's an awful lot of interest from the building owners in investing in energy Efficiency areas and it's at an all-time high they did a survey and They're seeing a pretty significant increase in interest in this area, but again No specific mention of the building envelope where some of the energy savings were another surprise in energy consumption in the US is The president asked American businesses to make a climate change pledge And we're seeing companies responding that out in a big way and committing to reducing demand side energy and related greenhouse gases And as an example Kingsman is mandated to be net zero energy by 2020 and So we're seeing lots of Companies participating in that well-known names that you're familiar with Ikea Walmart and lots of others So going back to the issue of financing The challenge again is in the ROI and the net present value for a sound business case here So we did a we did a project in Boston a few years back. I spoke about it last year, but it's worth mentioning again It was a 500 unit existing multifamily housing public project We did 192 units they were three seven-story mid-rises and this cladding just went right over top of the existing brick brick here cladding there and Basically the cladding itself not counting the windows or any of the Ventilation side of it which was all dealt with The the opaque envelope accounted for a 30% improvement over baseline over all the project delivered 52% improvement They had actually predicted 72% but that's another story The the key clue there was they didn't do commissioning so that's very important which passive house would require you to do I also want to speak to the advantages of a of Advanced manufacturing system. So this is just one Hybrid system. There's lots of them out there and what I mean by that is they're manufactured off-site. They're taken out and they're put up They're not built one Component and then another component and then another component on the job site with the labor shortages we have we're finding a lot of late defects in the construction buildings aren't performing to the level that they were designed for and So there's a lot of benefits in bringing these types of systems out much raster construction times less waste Less trades less late in defects So one of the things also that's happening out there And this is somewhat of a debate is mandating or Should it be voluntary benchmarking and so by benchmarking I mean in the larger cities We're interested in knowing what these older buildings are Using an energy. We want to know who are the energy hogs and at what level when were they built? We can tell whether they have insulation in them Whether they don't have insulation in them and by benchmarking then you can figure out where you're going to get the biggest return on investment on recladding or updating the building so There's projects like the city energy project where 15 cities now have benchmarking disclosure laws And in some cases We're seeing architecture 20 30 districts, which is a voluntary program. So we're seeing a mix of this But as of the summer of 2015 the city of Orlando made an 18 million dollar energy efficiency investment in public buildings and they did these audits on 55 Municipal buildings and at the completion of the project the city will save up to 2.5 million per year and energy cost and the savings will help pay for the cost of a new police headquarters That's currently in construction. So these are the kinds of things that you can also benefit from All you have one minute. Yep, I'm all done. So the we need tax reform for the financing We need a few policies just on high performance building and we're glad to see the Conference taking place on the energy bill. Thank you so much Now, thank you the one thing that bothers me crazy as I deal with my commercial clients on picking technologies We talk about window building envelopes we're talking about the outer part of the building the roof the sides the wind of course the windows and So they'll put an insulation And you're trying to increase the r-value the insulating value and they don't change out the windows That may have an R1 have no insulating value. It makes me furious. So I'm really glad that Intas is here and Or miss Sebulas did I pronounce that correctly? Yes, it is unbelievable is here to talk about what makes me so angry to reduce my blood pressure Go thank you Scott. Thank you so much for having us here. My name is Aaron. I'm a Sebulas I'm a principal at Intas windows where manufacturers of super energy efficient windows and door systems And I guess this is the panel where you bring your toys, right? I love As some of the panelists previously has mentioned in United States we have about five million commercial buildings and They actually contribute to about 45 to 50 percent of green greenhouse gas emission So that's a huge huge problem that we're facing and Smallest improvement in the commercial buildings, especially can impact our planet significantly Now the interesting fact is that those five million buildings that we're talking about They're probably 99% of them. They have aluminum windows and This is the weakest link in the building envelope. This is the low-hanging fruit for all of us So aluminum windows and single pane exactly with holes in them, right? And even double pain, right? So So these So other than structural performance the aluminum windows do not bring anything Else to the building in terms of the extra sound insulation and better comfort So what Intas is doing is we're really changing the market as cliche it as it was sound one window at a time And I'll I'll give I'll give a little bit more Details to it. So we're manufacturing a steel reinforced polymer window this window Cost Approximately the same as double-pane generic aluminum window, but outperforms that window by three times Three times no extra cost Right and we have a lot of great examples. We've installed these units in numerous passive house projects residential commercial applications, especially there's a multiple affordable housing passive house projects happening in Pennsylvania And they're using these systems because they're affordable and because they perform to the passive house level So what we've done for the last few years. We said well these windows perform significantly better than anything that we've seen not only in a passive house, but why don't we take them to a Mainstream markets market rate buildings and we'll see what happens then so just in our backyard three years ago We finished We were a part of one Project. It was a capital city charter school retrofit project. It's a hundred sixty thousand square feet facility And they were doing a retrofit by the way, they did not do anything with the building envelope They did not insulate that they just did the interior finishes and We were able to actually convince an architect and general contractor instead of using double-pane aluminum windows to use these triple-pane polymer system windows And you know what happened this building now saves seventy thousand dollars annually Without really paying anything extra initially. So kids are getting much more comfortable classrooms They they've increased sound insulation tremendously. So the the the Efficiency of kids studying in those classrooms improved significantly as well now this building also we've calculated that the carbon footprint Reduction because of the switching To triple-pane polymer windows was eight hundred seventy seven metric tons when I hear the metric tons carbon dioxide metric tons I never really could connect the dots but Some statistics you might probably not have known one tree can absorb up to 48 pounds of carbon dioxide a year only so what that eight hundred seventy seven metric tons really mean is Equivalent to 40,000 trees a year. So that's only one improvement that did not cause them anything That's equivalent to 40,000 trees So we've done a lot of other projects similar to these in multifamily buildings were instead of double-pane aluminum We brought in triple-pane polymer systems so what we are trying to really say here is if you do enough research if You if you look at the products out there you can significantly improve your buildings not only residential But also in a commercial scale and make a huge impact to our planet here here. I want to point out I'm a Adjunct professor at George Washington University I teach two interdisciplinary courses on sustainable energy and I tell my students It is always less expensive to save energy Then generate it from any source So it is always less expensive to save energy and that's what we have here So now we're moving into systems in the building and so we have ultimate air which I love the name of that company ultimate air and Luke Langals did I pronounce that right? That was pretty close. Yeah, I'm Luke Langhouse. I'm from ultimate air go for it All right director of business development. I've been with ultimate air for four years We've been a United States manufacturer for over 20 is special here, too, which is very impressive to me I like yours too. No, I don't want to go So we've been a US manufacturer for a long time We focus only in the high-performance building sector, which means we only build products for passive house and similar building styles We build energy recovery ventilation systems right now. We've had ours on the market for over 15 years This technology is basically an exterior exterior ventilation machine bringing in fresh air and removing the interior air but without wasting your energy It comes with a heat recovery medium in it. I don't want to get too technical But good capital hill It basically is like having your windows open in the middle of winter but without wasting your heat I mean, that's the idea in a passive house style construction or net zero energy This becomes important because we tighten these houses up to save energy We do better air sealing better insulation better windows and naturally our buildings do not infiltrate air anymore These windows right here are letting in fresh air constantly no matter what time of year it is So in this room, maybe not as important, but as we would make a building like this a little more energy efficient We would require a system like this From ultimate air standpoint we we get to work in almost every green building certification. There is I mean We've been doing this a long time. So energy star lead living building challenge green globe passive house All of these programs are fantastic for bringing green building to the masses and to everybody We find passive house to be the best solution to do a market affordable energy efficient building This means that in our experience with all the projects we've done which is every we've done projects in every 50 states We got thousands of units in operation. So we've seen them all but passive house really Brings the best bang for the buck and I'd like to give an example of a project. We did in Virginia that was built for five dollars per square foot less than the building next door of the exact same size and Uses 60% less energy. So this type of construction doesn't always have to be super expensive And I think that's a big misconception in the industry when people look at green building They think solar panels which are great and all these other technologies and they think added cost added cost added cost Who pays for that cost is that the building owner the government who's going to do this? But I think if we look at the experts we have in the United States Practicing right now you'll find that a lot of these projects aren't costing any more to do. Yes You have to add ventilation and windows and all these other things, but you save From other standpoints of the building the key is just to look at it from the design standpoint when you start designing a building and Accept that energy use is going to have to be one of the criteria use when going into that design Which anybody who builds past FALSE net zero lead platinum can tell you design it that way up front Don't try to add it on later Here here good point which leads into our last speaker and so this is Xander America, Inc. John Rockwell Scott imagine if you will the difficulty of being the last presenter in the last panel preceded by a ventilation person, so I Will amplify what Luke has said about the importance of ventilation in low-energy buildings what I found so stimulating about working in buildings that have That really achieve extraordinary energy goals is that the interrelationship of all the systems whether it's ventilation or fenestration or envelope All those things have become you become very dependent on the other on the other Professions what I do want to say what distinguishes Xander America from a lot of other ventilation companies is that we offer not just the box That is the heat exchanger But we offer the entire system of distribution of air for that a lot of ventilation companies use the ERV or HRV and tie it to the existing duct work for forced hot air or air conditioning systems And we believe in decoupling that so that when you don't have the heating season or the cooling seasons shoulder seasons For instance, you still have a dedicated decoupled source of high efficiency heat recovery or energy recovery ventilation Works flawlessly our system has a small tubular system that fits right inside cavities wall stud walls or under slabs And it really directs air where it needs to go So if you extract air continuously from bathrooms and kitchens as you are required to do by code either Intermittently or in our case continuously 24-7 you then supply air in the same exact amount to places where you need that That's generally in bedrooms at nighttime with windows and doors closed co2 levels can spike unless you provide fresh air So most people who find the room stuffy will open the window at night That's great in Honolulu or San Diego or Costa Rica, but it's not necessarily good in places They're dominated by heating and cooling to be able to control or if there are safety security and noise issues It's nice to be able to leave the windows closed the the myth of you can't open the window in a passive house Is just that you can open if you'd like but you'd use the criteria of when you'd open a window If there is a street sweeper going by twice a week You might not do that because of the dust that might come in or if it's an unsafe lower floor urban neighborhood Or if there's a lot of pollen about but a filtered Ventilation system is a great way to actually increase the indoor air quality to exceed that which is outside your building And a dedicated decoupled system to do so with efficiencies approaching 95% of whatever that temperature difference is is an extraordinary way to achieve that So and I think the other issue as we have been tightening up buildings meaning putting more insulation and better windows That you have outgassing in buildings you have chemicals that you use to clean your buildings and your dishes and your laundry and other and coming out of your carpeting and your Furniture and you do not want that stuck in your building You want that the hell out you want it moving and so this is a technology That will make you not only save you energy, but make you healthier and you're my age You know you want to look healthy. We have a few minutes for questions. Anybody have questions. Here's your chance. Ask a question Go for it Nothing. Oh there good Actually You two are instrumented, correct Why don't you talk give up? We have lots of different control. Sorry. We have lots of different control options available We've done co2 control meaning that the more people you have in your house the ventilation systems naturally going to ramp itself up and down Ventilation is always going to cost some form of money even though ours are going to be very efficient So we're going to be the least We still want to make sure we're not over over ventilating when we don't need to so as far as a smart home goes We can do motion sensors co2 control we're looking at VOC Control to basically boost the ventilation when you need it. That's the most important thing as far from fresh air standpoint Very similar in a lot of ways the thing I would add is With respect to bringing fresh air that's cold in in wintertime and exhausting moist air You oftentimes can have condensate buildup and what you want to prevent is frost from happening So frost protection is a key ingredient of any ventilation system It varies and how manufacturers do that sometimes people ramp down the supply fresh air intake preserve the outgoing Exhaust air however that will depressurize a building I'm not sure if that's a foreign topic to anybody But if you suck more than you blow you may withdraw fumes from combustion appliances or Fireplaces or dryers or things like that. Not so much problem with a dryer Begun becoming more aware of temperature sensors that monitor when that's going to happen to the system automatically stays in balance and Can control frost protection is one way and others humidity management human stats. We're moving into you saw Google buying nest thermostats as an example Yeah, and the reason they're doing that obviously is they want to get into your home and how you how you handle yourself but in fact, it's setting the stage for a user-friendly approach to how you control your heating your cooling and And lots of other appliances and we are just at the be we were in the infancy of this But it's a very exciting point of view I just want to amplify what cat said earlier and that is a low energy high performance building is not a Geeky smart building. It's just better envelope better windows better everything you don't have to think about it any differently But you will experience the comfort that you never knew before and it really most people don't care about the energy efficiency and the watts per CFM and things like that They want to know that they're not gonna have a chill in their neck when they sit next to a single glazed window really That's what boils down to yeah, that's right, and I'd like to add to keep it simple is really the trick So I forgot to mention The passive building standard also adds the comfort criteria as you said right it keeps it always comfortable in the whole building It also adds resilience. So we're insulating to a level where the building essentially can be like just by itself It's so simple and passive that it can't actually Exist without all the complex technologies and actually Studies have shown that if somebody temp tinkers with the thermostat or even a nest thermostat that would adjust to your behavior That would result in higher energy consumption than if you left it alone in a very well-designed passive building Yeah, that actually proved out in the reclad that I was talking about the the new boiler systems Allowed thermostats programmable thermostats in each each quarters Where before it was set at the at the boiler and everybody got the same thing Old habits are hard to break. They were still regulating by opening windows and closing them and that caused the building That was part of that differentiation from 52 percent to 72 percent None of these guys put an electric shock stuff that would prevent that I just also wanted to just mention on that topic that we are we are seeing sensors being put in at least in the commercial side And they're collecting big data, which all goes back to the benchmarking thing as well It doesn't really regulate like you said, but it is recording data so that we can understand how buildings are performing That's a quick one. Oh, it's it's good for everything. It's good for new build for retrofit for commercial For residential we're seeing everything really industrial size. Oh, oh exactly like a production facility is not a problem We are seeing high rises Medical facilities everything Any other question? Yes Hey bail igloo It's not a material. It's an energy use. It doesn't matter what you use It's it's it's it's restricting airflow and exfiltration and making sure you have enough our value depending on your climate Right so think of it as like a Miles per gallon for a building right so you have that goal and then you design the envelope to meet that goal And it doesn't really matter what material you use at least sound practice, you know, you can do it You want to go to foam you can do it? Any other questions? Let's give a round of applause for this great panel. Thank you all
