 Okay, well, thank you. It's great to be here and I have heard of bids but have never Been in this space or been into any reactivity So it's a great opportunity for me to find out more about you and I'm delighted to have the opportunity to share with you Some of the work we've been doing so again. My name is Trees pepper. I'm the associate director of the sustainability infrastructure of citrus So this I for energy was the old name and that and we were incorporated along with water and Transportation into this new name this new Initiative which is sustainable infrastructures. I'm also the director of a enabling technology development program At Calvary Institute for energy environment and which is merging with the Berkeley Energy and Climate Institute Becky So I wear a couple of different hats So what I'll be doing is it's hard to describe all of the activities that we're working on I'll just highlight a few of those and Look forward to your questions the basic idea. I am academic staff I conduct research in and manage research in energy related projects on campus I work with people from the Lawrence Berkeley lab other campuses. You see Davis and other researchers on this campus At UC Berkeley a lot of my work I was educated here both in neurobiology and psychology as an undergraduate and in architecture building science for my PhD And I tend to do research in buildings user interfaces So I still try to maintain both the psychology component as well as the energy related component And the goal of much of the research is to just create better comfort environments comfortable environments for people as well as reducing energy consumption and So the first project I'll talk about this is going from sensors to electric grid. So starting off with the smallest component We've been using wireless sensors in our work for a number of years now and they continue to get lower in cost and higher in capacity and computation and things like that There's one of David Culler's students in the software defined buildings group right now is developing a very low power Platform called storm firestorm I'm using a raspberry pi basically to in adding a temperature sensor and carbon dioxide sensor on it With these if you distribute them around a building you can start getting information about gosh How many people are in the space is a space occupied is the temperature appropriate for these people and you can do A number of things one is to make the space is more comfortable for people But also to gosh if you know that a lot of people in the space you can blow in some more air and make the room very comfortable in terms of Evolving in buildings where or in meeting rooms where it starts to get hot and stuffy and people start to get sleepy Well, if you blow in some fresh air often that can solve that that issue I'm also involved in a project developing a low-cost Anomometer the anemometer is basically it detects Air flow and air volume and the idea is if you can put this in a space and a fume hood and a Duct you can detect the amount of flow that's going to a space and again optimized to make sure you're getting the right amount of Flow at the right time and again save energy another project I'm working on with Carnegie Mellon University and the Silicon Valley campus is to look at if you provide sensors at a distributed Level a lot of times we have building energy monitoring at a whole building level The idea is if you can start looking at zone levels at room levels It one you can provide visibility to people how much energy are you using for your computer your monitor your fan your your heat or whatever and And they also give that visibility to the facilities manager so they can start saying gosh everyone in that space is cold They're bringing in their Peters that sort of thing so we've been doing a A number of different projects in this space Another project this was funded by the California Energy Commission called changing the rules It's also based at the Center for the Built Environment across campus and architecture the idea behind this is to develop occupant responsive building controls and so the idea here is they have a Personal comfort system and involves a foot heater a personal fan but also this chair that can provide heating and cooling directly to a person and we also have this web-based application that It can pull for occupant satisfaction. Are you too warm? Are you too cold? But they also allows people to get control over their local environment And so what we're doing is integrating these two so that you have information from the building automation system in a large office People have control over their local space with these chairs and this application and we're just saying again Can we keep people comfortable? Can we save energy through this system a? Project that again David colors offer to find buildings group across campus has been working on for a number of years is a platform Once you have these sensors Once you have this data from many different sources whether it's interval meter Whether it's a building automation system or what have you to bring all that the aggregation of time series data into a single Database and so this platform has been developed really over the last seven years We'll be using this platform in a project that will start in a couple of months We're working in conjunction with the transportation sustainable resource center on campus to look at Electric vehicle charging and home so once you can combine interval meter data from whole home data Thermostats lighting controller general. I mean this is the Internet of Things right and but also combined that with electric vehicle charging You can start doing things like balancing load Loads you can start looking at say if they have a foldable take system on their house to start balancing load with supply We're also looking at aggregating a number of houses into a neighborhood and start looking at a neighborhood aggregation Looking at that scale So this is the extensible building operating system services x-boss and then Slash v is we're looking at using this for electric vehicle charging another project that'll start in a couple months is It's led by the electric power research institute down in Palo Alto But we're subs on it is designing thermostats for low-income households And the idea here is looking specifically at this population and gosh, what do they need? What are their? What are some barriers? What are some of the issues with this population? Do they need a different kind of user interface? Do they need a different kind of? A simpler control I my dissertation was on thermostats So I know a little bit about this area and how most people can't program or don't program their thermostats You know nest is a nice example of a learning Thermostat, but even with that I've heard many stories of people not being able to use their nest properly So that's what we're going to be looking at here We're going to spend a lot of time just looking at What are the issues and getting to know this population better and then trying to design a very low cost Solution so that we can again make sure that people are able to use their thermostats Get the thermal comfort they need but also save energy another project done This was done in conjunction with Lawrence Berkeley National Lab A colleague of mine is working on this scoping study to look at Direct current DC power integration with the goal of these zero net energy That these that's the goal is to reach that and the idea is that A lot of the renewable energy sources are direct current like photovoltaics And a lot of the loads inside your house or in your office, but this is more looking at homes Are supplied by direct current right we see the transformers for our computers or monitors Small motors and things like that. So what they're looking at in this study was looking at well, gosh Why can't you just use that direct current power supply directly into the house for your loads for your direct current loads? And then this is the last project. I'll talk about this the micro synchro phaser project This project has been been going on for about two and a half years Since in its last few months of operation the idea here is you have a device That can measure the phase angle of current or voltage And it does it's a high resolution you get like 10,000 points per second And it's time sinker synced so you could have two different devices at a distance away And what you can do with this is that you can start looking at gosh when the voltage starts to dip What can you do immediately to to help out? They're actually still looking at with this data trying to figure out the different applications They can use for it But that's at least one that they know right away that they can if you start seeing changes in the voltage Very quickly you then you can do something about it with this information So and this is looking at micro synchro phasers for the distribution grid not for transmission side So that's what I Brought to show again going just from sensors and then all the way across to looking at some easier interface stuff And then looking at the big picture of the utility grid So I think with that We can have a discussion. I'll take your question Thank you
