Things are rolling smoothly for the Green Buildings Team as we move into the second half of the quarter. Our team has continued our weekly group meetings with Todd, and these have been very effective in promoting clear communication and yielding data for credits. As we collect and tabulate information, new questions always arise, and these meeting give us a chance to clarify the LEED requirements and our team’s approach. Oftentimes, we will email Todd beforehand so he can look into a question beforehand or direct us to other contacts for follow up.
For the Water and Energy group, we were wondering whether to pursue Whole Building Metering or Whole Building and Subsystem Metering. If we were doing the first approach, we would need to know: total number of meters, meters owned by third party, meters owned by project owner, total measured water use, estimated annual use, a description of each meter, and a summary report from energy star. The second approach requires that at least one of the following metering systems must be in place: irrigation, indoor plumbing fixtures, cooling towers, domestic hot water, and process water. After speaking with Aliana Lungo-Shapiro, the sustainability manager of Housing, we learned that UCLA does not have a very complete metering system. Some buildings are on their own metering system, while some are linked with other smaller complexes. Since most don’t have submeters in place, the utility usage will have to be prorated for most of the buildings, such as the De Neve complex.
In our weekly team meeting, we discussed our final written report and presentation to the ESLP ART program. We split the report into several subsections and assigned these to different team members. I will be writing about our research methods over the past two quarters. This has included using static credit sheets off the LEED website to determine required data, utilizing Todd as the Principal Project Planner of Capital Programs, interviewing contacts such as Aliana Lungo-Shapiro and Hank Knapp to receive more specific housing data, and collecting in-field data such as recording water saving features in dormitory bathrooms for specific buildings. For the final presentation, we will quickly demonstrate the process of passing a specific credit.
An example we might use for this is EAc4 (Energy and Atmosphere Credit 4—on/off site renewable energy). There are two approaches to earning this credit. One is for purchased electricity / renewable energy certificates which is possible as a function of the electrical usage by building, derived from meter data provided by Housing. The second path would utilize information from the campus cogeneration plant. The plant burns methane biogas from a landfill as a portion of its fuel supply which has been calculated as a proportion of the electrical demand of each campus building. By applying this factor to each building’s energy usage, that will give a number for the renewable energy used.
