Chuck Frost, and Erin Fenley of the UCB Energy Office talk about their efforts to drive down electricity use on the Berkeley campus. This program will shift the onus for electricity use on each of the 28 Operating Units on Campus. Mypower.berkeley.eduTranscriptSpeaker 1: Spectrum's next. Speaker 2: Okay. Speaker 3: [inaudible].Speaker 1: Welcome to spectrum the science and technology show on k a l x Berkeley, [00:00:30] a biweekly 30 minute program, bringing you interviews, featuring bay area scientists and technologists as well as a calendar of local events and news. Speaker 4: Hello and good afternoon. My name is Renee Rao and I'll be hosting today's show. Did you know UC Berkeley has an energy office and an energy incentive program? Our guest on spectrum this week are Chuck Frost, the first ever energy manager of the UC Berkeley campus and Aaron family, the energy office communication specialist. [00:01:00] They talked with Brad swift about the programs the energy office has launched to drive down electricity use on the Berkeley campus. Here's the interview, Speaker 1: Chuck Frost and Aaron Fenley. Welcome to spectrum. Thanks for having us. Yeah, thank you. You work at the University of California Berkeley Energy Office. How did that come into being? Speaker 5: Well, the university hired a consultant to look at ways to save money on the campus. One of the things they came up with was to reestablish the energy [00:01:30] office. Speaker 1: Yeah. And that was about three or four years ago when bane consulting came in to check out what areas we could save money, um, on campus. And that was everything from payroll to energy management. So we dove in from there and it's part of operational excellence program. Actually through the energy management initiative we have created the energy office. We have also created an extensive outreach program which has its own goals and energy incentive program, which [00:02:00] has financial goals and then an energy policy which provides a framework. Speaker 5: Might there be, while the energy office actually tracks and monitors and assist the campus in reducing energy and we try to improve the building performance also. Is there anything that's really different the way your energy office is doing it that distinguishes you from other places? I think it's the number of dashboards we're using. We've got [00:02:30] almost a hundred installed on the smart meters and then also the incentive program or you could put the bill out into the campus. So the 28 operating units, if they beat their baseline or you will give them money. And this year we're giving them about $170,000 back to the campus, but it can go the other way starting next year and they could owe us two so it can go either way. It's a carrot in a stick. But out of the 28 opportunities this year, 20 received [00:03:00] money and two what Ellis and our goal is really to have no one, no HOAs and put the money back into the campus. Speaker 6: And how is it that you tie into the dashboard? Would the data, where do you collect the data? How do you tie it in? Speaker 5: Each building has a meter that monitors the incoming power to the building and that goes to an obvious is the name of the system. And then the pulse energy pulls off the obvious server to populate the dashboards [00:03:30] and kind of throws the bells and whistles on it. Speaker 6: Now are you able to use the data to reflect on the buildings efficiency its system? Speaker 5: It's actually can be used as a tool to identify when you have problems in the building. It's a, it'll throw up a flag. If you're doing too much energy after it learns you're building, it really knows how you'll drop. However, on a certain day and the weather and things like that, that's the model that is actually forms. It takes a few months to learn the building and actually it really a full seat, you know, a year. [00:04:00] And then once it identifies and learns and models who are building, then you can actually have threshold or limits that will flag your attention. If you have drawing too much or not enough, it can go either way. But that's a good indication. It's a lot better to have sub-metering in a building, but it's, it's very powerful just to have, you know, a smart meter in a building. And is there a move afoot to go to this sub-metering? Absolutely unfortunate. It just comes with a price and so it's very expensive. [00:04:30] But with the technology changing and wireless and things like that are being used a little bit more and I think it's coming down. So probably doable in the future. If you look at all the utilities on campus, we average between 30 and 35 million. That's for water, steam, gas and electricity. Speaker 1: And the electricity itself is about 17 yeah, Speaker 5: that's what he paid last year. Speaker 6: And so year to year as units start to save, you're able to give what back to them Speaker 5: when the, [00:05:00] the main meter at the campus drops down. That that's how we really determine and then we break it down into buildings, how much each of the buildings. But we actually look at the main meter also and then we are showing for the first time in a number of years where we actually did reduce and that an average of 2% creep was what we saw since the 90s Speaker 1: so so we can really avoid that creep by keeping the engineers in buildings. They've been divided into zones to work [00:05:30] in specific areas on the campus in order to understand the buildings, know what's going on there, work with the building managers in order to keep them tuned up so that the creep doesn't happen. Speaker 6: And that's the front line? Yes, it's the building engineers and building managers. Speaker 1: Well through the energy office there are stationary engineers, electrical engineers that are working in the zones with building managers in order to make that work happen. Speaker 5: So even though the skilled trades, Speaker 1: our goal goals a little bit different [00:06:00] than a traditional stationary engineer example where we're looking at kilowatts and BTUs, we want to help in any way we can and improve the building. But our focus is really energy. So we work with the shops but we have a different spin on it. So this past year a lot of the work that was very significant in reducing energy use was through variable fan drives. Yeah. Speaker 5: Both frequency drive. So anytime you can vary the flow on a large motor, whether it's pumping water pumping here you can [00:06:30] actually, once you reduce that substantial savings. So we saw a lot of opportunities and repairing dries, putting in new drives and things like that. Speaker 1: You kind of have more of a consultant role Speaker 5: in a sense. We like to say we're looking and um, some people will call it low hanging fruit. They don't cost a lot of money to invest in, but it could be scheduled changes. You could be heating and cooling at the same time. There's a lot, actually a lot of savings in those two areas and really don't have to spend a lot. You [00:07:00] just have to identify what I'm an example in this building we're in right now, it was a while ago, they actually had a painting project, so they wanted the fans to run 24 seven and it was one of the professors at notice will look at the dashboard and how come the energy use went up and it didn't go back down. So by him asking that question, we investigated and we found out that they had put all the fans in hand. There was no schedule to shut down at night so that that was about a $45,000 [00:07:30] avoidance would have been allowed to run the rest of the year. So those kinds of things, that's what the dashboard really helps a lot of people a lot of highest looking. So you can see what's going on and start asking the questions, why do I have this little blip of power? Why does it jump up like this? And the energy officer will go out and investigate it and sometimes it's just interviewing people. Sometimes it's walking through mechanical rooms and every building has a story. So you have to kind of dig into it. Speaker 7: [inaudible] mm, Speaker 4: [00:08:00] you're all sitting just spectrum on k a Alex Berkley. Our guests today are chuck frost and Aaron finally from the UC Berkeley Energy Office. In the next segment they talk about changing behavior to save energy Speaker 1: and what sort of outreach programs are you operating to try to just drum up support and awareness. We do have a energy management resource center right here in Barrows Hall Room One 92 [00:08:30] and people can stop by and pick up posters and flyers and light switch stickers can get information about saving energy, specifically in labs, residence halls and office spaces. You can also come there or email us@mypoweratberkeley.edu and set up a time to have our student team and we have an amazing student team who conduct surveys in offices, labs. We come in and take a nice observational survey [00:09:00] of what's going on in the spaces, um, leave stickers and materials to help that area find out more about what they can do. People here on campus are already doing so much to save energy, but there hasn't been a single place that we've gone to that we haven't found a few recommendations, uh, to give. So we provide personalized recommendations to that area. Then we post those on our website so they can be downloaded by the whole office or whole lab. And Speaker 5: would someone get involved if they're interested in becoming part of [00:09:30] the student team? Speaker 1: We just hired our student team for the semester, so all of our positions are filled currently. However you can stay in touch with us through our website and through Facebook where I post different internships that are available and they come up each semester. Yeah. Speaker 5: On the maintenance and new building side of things, there's obviously an ongoing maintenance that's required by all the buildings and are you folks involved in specifying improvements that could be [00:10:00] integrated into that maintenance process? We actually try to help with the maintenance too, but again we are looking at, everything we do has to be related to energy savings, so things like just clean filters. We'll save energy because there's less draw on the fans. It's an ongoing challenge, you know with the funding and things like that for an adequate maintenance, but it's improving and it's starting to turn, which is really good. It really needs to campus because of the age does [00:10:30] require a lot of maintenance on the different systems and things like that. And with new construction, do you get involved in decisions that are being made about what to put in the various buildings? That would be the policy that Aaron was mentioning earlier. We actually, with the new energy policy, we tried to insert ourselves pretty early into the design phases of the project. Actually in the very early design conception is where we want to be inserted. So we can talk about that. And are there [00:11:00] other sort of stakeholders, groups like yours that get drawn into that process Speaker 1: about energy efficiency or other things? Oh, other things? Well, I mean you could relate it to accessibility issues in a building. It's a very similar type of thing. You're going to build that in in the beginning too. Campus buildings these days, it's not going to be an afterthought and we want energy efficiency to be seen the same way. Speaker 5: And Are you, you're pretty much limited to off the shelf kind of technology at this point. There's no way for you to really work with anyone on campus [00:11:30] on creating some new technology that might, aren't working with certain groups. The Center for built environment, they're doing a research project right now on personal comfort units, which the focus is right at your desk and not a zone, the whole room. And they actually having some pretty amazing results. They have also a heating and cooling chair. So you actually heat the whole building just there as you need. And so the goal is to try to get people to trade in their heaters [00:12:00] that they've got underneath the desk that they bring in from home and they don't want anybody to know about that draw 1500 watts of power with one of these more efficient, uh, personal comfort units, which draw about 40 watts. So they're actually, I had one in my office and I, I hated to give it up, but they had to use it for the research, but it really works good. It's very interesting some of the work they're doing. Speaker 1: I also worked with some students in computer science in order to help us develop a mobile available [00:12:30] site for our dashboards because right now in pulse dashboards or flash and they don't display on mobile devices or tablets. So some of our computer science students help to develop an html version where we're showcasing about half the buildings that are available on pulse. However, you can access those through your mobile device now. And is it just a matter of time before you get them all hauled? The building's done that way. I certainly hope so. Yeah. Yeah. Yes, it is. An ongoing project. Speaker 5: [00:13:00] There is opportunity for innovation that you're finding within absolutely. The campus people are coming to you with ideas which you encourage them. Yes, definitely. Definitely. Yeah. That's exciting. That's the best part of my job actually is meeting some of the people I'd never get to meet otherwise are doing some really neat research and it's cutting edge and to look at the campus as a lab. It really is because of the diversity in buildings and we've got some buildings that are a hundred years old and [00:13:30] on the behavioral side, what sort of push do you make there and how successful is that? Speaker 1: We have been developing a lot of elements for our behavior change campaign, the my power campaign, reaching out to all of campus saying that everyone has a role to play in reducing energy use. We can all turn the lights off, we can all unplug things when we're done with them. We've put out about 10,000 stickers around [00:14:00] campus reminding people to shut the lights off, reminding people to turn their monitors off and those had been put up through student teams. They've also been put up through our power agent team, which is a group of very committed champions of energy efficiency here on campus. Most of them staff members, a few students. And they are also along with our engineers, some eyes and ears of the buildings on campus and they can keep us updated on things that are happening in those areas where they work and study. Speaker 5: [00:14:30] Oh, I'd like to say that we value anybody's input. And you know, I've had people that are gardeners or browns and I've had custodians and various groups that will say, you know, the light was on and you know, the buildings lights are on and things like that and brought it to her attention. So it's just everybody's health. We can do this. It's going to a group effort. Everybody's working together. Speaker 1: Absolutely. And anyone who wants to report any type of oddities [00:15:00] or anomalies and energy use, sending an email to my power@berkeley.edu gets our whole team's attention and we get back to everyone within 48 hours and get on the problem. So those types of reports have really helped us resolve some issues Speaker 6: other than electricity. You deal with natural gas. Steam is a big part of the campus as well. And how does water fit into that as issues? Speaker 5: Right now we're just focused on electricity, [00:15:30] they initial phase, but we will expand into it, you know, working closely with the sustainability office and, and water is very important in steam and yeah, Speaker 1: our dashboards even have capabilities of showing water usage and steam usage. But right now we're pretty single minded in our focus on energy efficiency and reducing permanently reducing the amount of energy we use on campus. But the campus does have a goal of reducing potable water use to 10% below 2008 levels by 2020 [00:16:00] and you can find out all about that@sustainabilitydotberkeley.eduSpeaker 3: [inaudible]Speaker 8: spectrum is a public affairs show on k a Alex Berkeley. Our guest are chuck frost and Aaron Penley in the UC Berkeley Energy Office. In the next segment they talk about new technologies and surprising collaborations. Speaker 6: And how does the steam system [00:16:30] here interact? It's shared, right? It's across a large group of the buildings or not because not all the buildings are on the steam [inaudible] Speaker 5: on the core, you know you have some remote buildings that have boilers and things like that and so you're not using electricity at all to develop the steam. Oh, that is correct. So it's just all, it's usually natural gas or gas to do that. Speaker 1: But isn't the steam a byproduct of the electricity production? Speaker 5: You're absolutely right. We have a cogent plant that does cause of the [00:17:00] turbine generate steam that we traditionally use and then we have on boilers that are kind of a backup to that now. Speaker 6: So that's then on top of the power you draw from PGNE the cogeneration. Speaker 1: We actually produce that energy and then sell it back to BJ to PGNE and then we buy it back. Speaker 5: We give 10 cents is the number we typically give because it's kind of a blend, an average of what we pay Speaker 6: [inaudible] I'm interested in the new technology that you're looking [00:17:30] at. Speaker 5: I think fault detection has actually been around for awhile with your control systems. You trended in the building and then you traditionally would analyze it, an engineer or somebody would look in and analyze it. So you automate that. And so what is really changed, and I think it's really good for the industry, the HVAC industry, is you've got people like Google and Microsoft and people that were never in the game before. Now I want to start mining the data from the buildings, analyzing that data for a fee and helping [00:18:00] with the fault detection. So it's a game changer at the industry. Probably in the last five years has changed more than it did 25 years before that. It's amazing. So we got new players in the game and wireless as well. Wireless is very big too. Yeah. The technology, Speaker 6: is it proving to be as reliable as copper wire? Speaker 5: I think it is. It's starting to be embraced by everybody. You have different technologies, ones that require repeaters and then you have mo technology, then self networking [00:18:30] and things like that. So even now we've got pilots going on that are pneumatic thermostats that are really wireless electronic thermostats that go back to a server and the pneumatic combined. And so that allows us to get down to the zone level to really control a building and really look for the energy. A zone would be like the room we're in now and then with the new wireless lighting that actually it looks at occupancy, it looks at a temperature. Also you can start pulling and really getting a good profile or [00:19:00] you're building when the energy is and when it's occupied and things like that. So those newer technologies are very promising. Speaker 6: Obviously you're going to drive the use and drive efficiency at cow and it's going to get harder and harder to reduce the use. Your Delta is going to get smaller and smaller. Where do you find new efficiencies? Speaker 5: We like to call it mining for Golden Nuggets and the nuggets are harder and they're deeper to find as you move forward, [00:19:30] that's for sure. But we've been working with a Berkeley national lab and also the Pacific Northwest National Lab and PGNE Energy Center and facility dynamics on ways to train our technicians to, to find those golden nuggets. So we're putting the technicians out in the field as we mentioned in zones in the learn the buildings and then they'll get the deeper look at the buildings once they understand the buildings, get more familiar with it. So that's where we're hoping to continue the process. But it is it, you're absolutely right. It's harder. You keep going in [00:20:00] whether you call a golden eye, gets her low hanging fruit, there's less and less. This orchard has been picked over pretty good. Speaker 6: This is what's the legacy of your data collection and distribution at this point? Speaker 1: Oh, right now we started April, 2011 and we are just now finishing up our first annual report that contains all of our, our data from the initiative since the inception, so that will be released as soon as it is approved. It is in its final [00:20:30] draft stage. Speaker 5: What was the biggest surprise for you when you started this process? I don't know if it was a surprise, but I was just amazed at how much of the small little pockets of research that are going on than it actually looking people coming forward. And I'd never heard of the before the center for built environment and just amazing what they had been doing for 20 years and they were a great group and they really understand building comfort and the looking at new technologies and things like that. So this personal comfort unit and [00:21:00] again David Color and computer science students, that was just an early surprised me. And then it would be looking at energy and buildings and some of the tools they've shown savings with lighting and just the smart apps they were developing and where they could track you through a building. They knew what you liked in lighting and and the environment and they could actually start to modify the building and the interface with the control system at the building over citrus in the Er. It was just amazing to me. It was a surprise. Okay. Speaker 9: And the biggest challenge going forward [00:21:30] in near term Speaker 1: for you guys is what? I think for me it's to keep reminding people that we're not done and we still have to keep remembering to incorporate energy efficiency into our daily actions. One of the most surprising and interesting things in this work has been seeing what people's attitudes towards energy efficiency are and some people believe that they're doing everything that they possibly can and we continually find that there's probably even more that [00:22:00] you could do somehow or another. So continuing to incorporate that into your daily work routine or your daily coming to school routine is very important. Speaker 9: Chuck Frost and Aaron Fendley, thanks very much for being on spectrum. Thank you for having us. Thank you so much and good luck with saving energy. Thank you. Speaker 8: [00:22:30] If you're interested in reducing energy use at cau, visit the website, my power.berkeley.edu there you'll find building dashboards and strategies for taking action. Speaker 3: [inaudible]Speaker 8: spectrum shows are also archived on iTunes university. We've created a simple link for you. The link is tiny url.com/cadillacs [00:23:00] spectrum here at spectrum. We like to highlight a few of the sides to technology events happening locally. Over the next few weeks. Brad swift and I Speaker 9: present the calendar. The last few days of the bay area science festival are this weekend tonight in San Francisco, science improv blitz where comics and phd students synthesize laughs for the sake of amusement and learning. This is happening at the south of Market Street Food Park [00:23:30] four 28 11th street from 7:00 PM to 8:30 PM this is a festival event and free discovery days at at and t park. A T and t park will become a science wonder and when Bay Area Science Festival Speaker 4: concludes again with the Free Science Extravaganza last year, more than 30,000 people enjoyed a nonstop program chock full of interactive exhibits, experiments, games, and shows all meant to entertain and inspire [00:24:00] with more than 150 exhibits or something for everyone to unleash their inner scientist. This festival grand finale is Saturday, November 2nd at the home of the San Francisco baseball giants at 24 Willie Mays plaza in San Francisco. It opens at 11:00 AM and runs until 4:00 PM Speaker 9: the Mathematical Sciences Research Institute and Berkeley City College will host a free public talk on verifying greenhouse gas emissions by Dr Inez Fung as part of the lecture series, not on the [00:24:30] test, the pleasures and uses of mathematics. Dr Inez Fung is a contributing author to the assessment reports of the intergovernmental panel on climate change, a scientific body under the auspices of the United Nations. Dr Fung will discuss how we measure and verify claims about emissions related to global warming. Dr Fung is a professor of atmospheric science at UC Berkeley where she has studied climate change for 20 years and has created mathematical models that represent [00:25:00] CO2 sources and sinks around the globe. The event will be held in Berkeley City College Auditorium on Wednesday, November six from 7:00 PM to 8:15 PM RSVP for the free event online@msri.org Speaker 4: the November installation of the monthly lecture series. Science of cow will focus on art inspired by science and mathematics. You see Berkeley Professor Carlos equin will speak about how math and computers [00:25:30] are being used to create new artwork every day. He will also try to answer the nearly insoluble question of whether art or science came. First. Professor sequined began his career at bell labs as part of the group that created the first solid state image sensor compatible with American broadcast television. He later joined the faculty at UC Berkeley where he eventually focused on the development of computer aided design tools for architects and mechanical engineers. Professor sequent has also collaborated with many artists over the years to make the most of computers [00:26:00] and the emerging rapid prototyping tools to create geometrical sculptures and a wide range of scales and materials. The lecture will be held at 11:00 AM on Saturday, November 16th in room 100 of the genetics and plant biology building on the UC Berkeley campus. The lecture is free and open to the public haired spectrum. We like to share our favorite stories about science. Brad Swift joins me for the news Speaker 9: science daily reports that scientists at the University of Wisconsin Madison [00:26:30] have constructed a three dimensional model of the so-called missing link, cold virus, Rhino virus c Rhino Virus C is believed to be responsible for up to half of all childhood colds and is a serious complicating factor for respiratory conditions such as asthma. Together with Rhino viruses, a n B. The recently discovered virus is responsible for millions of illnesses yearly at an estimated annual cost of more than $40 billion in the United States alone. [00:27:00] Because of the three cold virus strains all contribute to the common cold drug. Candidates that focused on rhinoviruses a and B failed antiviral drugs work by attaching to and modifying surface features of the virus. This highly detailed three dimensional structure for rhinovirus c will give pharmaceutical companies new targets for designing cold thwarting drugs. Speaker 4: UC Berkeley scientists have designed a satellite [00:27:30] that could detect large fires across the western United States by snapping a constant stream of photos of the earth below. Then scanning them for new hotspots that could indicate wildfires. The UC Berkeley teen described their plans for the satellite known as the fire urgency estimate or in geosynchronous orbit or flags. In the October 17th issue of the Journal. Remote Sensing Lego works by analyzing its infrared photos using a computer algorithm to detect differences in the land, especially bright lights [00:28:00] that may be fledgling fires. The program can analyze the entire west in minutes. Creators hope that the early detection of wildfires help to prevent loss of life and widespread damage that usually occur as a result of extensive wildfires. Researchers hope to raise the several hundred million dollars required to build the satellite through a combination of public and private means. Speaker 9: The Northern California chapter of the Society of professional journalists has awarded greater good science center editor in chief [00:28:30] Jason Marsh, uh, 2013, excellence in journalism award for his story. Why inequality is bad for the 1% a gripping look at how income disparity can negatively impact both the wealthy and the poor. Relying on cutting edge research. Jason's story illustrates the ways in which having wealth may adversely affect an individual's ability to be compassionate, understand social cues, and trust others. Those deficiencies can hinder social connection, a key part [00:29:00] of our happiness and our physical health. To read the article, go to the website.
