The part of the Climate Pollution Reduction legislation that required state agencies, colleges and universities to track and report the energy use of buildings was codified as RCW 19.27A.190. It is also known as the Energy Benchmarking Law. This report is in response to RCW 19.27A.190 (5), which requires the Department of Enterprise Services1 (DES) to prepare a biennial report summarizing the state portfolio manager master account reporting data. Four Steps Required by Energy Benchmarking Law There are four steps required by the Energy Benchmarking Law: 1. Benchmarking building energy use 2. Preliminary energy audits 3. Investment grade audits 4. Building energy retrofits Benchmarking and Preliminary Audits in Buildings Owned by Agencies, Colleges and Universities Between 10 percent to 15 percent of buildings greater than 10,000 square feet in size owned by agencies, colleges and universities are benchmarked at the building level. DES recommended audits for buildings or campuses using more energy than the average for an agency, or more than the average for college or university campuses. Preliminary audits were also recommended for agencies, colleges and universities not benchmarked at either the building or campus level. Of the 78 percent of colleges for which preliminary audits were recommended, 44 percent completed preliminary audits since 2010. Although agencies and universities have also done a substantial number of preliminary audits, DES was unable to confirm that the preliminary audits were comprehensive and included all facilities. Benchmarking and Preliminary Audits in Buildings Leased by Agencies, Colleges and Universities After January 1, 2010, agencies, colleges and universities could not enter into a new lease or renew a lease for a facility with a score below 75, unless certain conditions were met. DES was directed to: Establish a process to determine viability of relocation when a facility leased by the state has an energy rating score below 50; and 1 Previously required of the Department of General Administration, which was one of the agencies merged into DES in October 2011. 3 In consultation with the Office of Financial Management, develop a waiver process for facilities leased by the state with an energy rating score below 75 entering into a new lease or lease renewal. In the absence of funding, response to the benchmarking law from agency to agency was inconsistent, making it impractical to develop these processes. State agencies have benchmarked more than half of leased buildings greater than 10,000 square feet in size for which the agency paid the utility bills directly. Colleges have not benchmarked leased buildings. Universities have benchmarked one leased building. Investment Grade Audits and Building Energy Retrofits The Energy Benchmarking Law requires investment grade audits by July 2013 for energy conservation measures identified in Preliminary Audits. Building retrofits that implement all cost effective measures are required by July 2016. Overview Energy Benchmarking Law As noted above, in 2009, the Legislature passed E2SSB 5854 Climate Pollution Reduction—Energy Efficiency. The part of the Climate Pollution Reduction legislation which required state agencies, colleges and universities to track and report the energy use of buildings was codified as RCW 19.27A.190 and is also known as the Energy Benchmarking Law. The text of RCW 190.27A.190 is in Appendix A. In this law, benchmarking is used to identify opportunities for energy savings in buildings occupied by state government. Buildings that are identified as having high energy consumption are then required to proceed through a process of energy audits. If cost effective efficiency upgrades are identified during the audit phase, the agency is directed to implement the upgrades. What Is Building Energy Benchmarking? Building energy performance is benchmarked by recording a building’s energy use for one year, to establish a baseline. This makes it possible to compare the energy performance of a building with itself over time. Benchmarking is also used to compare energy use in one building to use in another, or to compare the energy use of one campus of buildings to another. Benchmarking results are typically expressed as Energy Use Intensity or EUI. All energy consumed within a building, such as electricity, natural gas, propane, wood or steam, is converted to a single common unit of measurement, the British Thermal Unit (Btu). Total kBtus (1000 Btus) consumed over one year are then divided by the gross square footage of the building to express the average energy use of the building per square foot, or kBtu/Sq Ft. This value of kBtu/Sq Ft is the building’s EUI. 4 Buildings with a higher EUI use more energy per square foot than buildings with a lower EUI. The Benchmarking Law specifies the use of Portfolio Manager, a free, web- accessible utility management application developed by the U.S. Environmental Protection Agency (EPA). Portfolio Manager is used to document the building EUI. Also, for a limited number of building types, Portfolio Manager provides an energy rating score. EPA Portfolio Manager provides scores for Rated Building Types, including offices, warehouses, dorms, K-12 schools and a few others. If a building in the Portfolio Manager is a Rated Building Type, it will be given an energy rating score, similar to the percentile scores used to compare students on standardized tests. The energy rating score can be used to compare a building to other similar buildings. For instance, buildings that get a score of 75 are in the 75th percentile, and use less energy per square foot than 75 percent of similar buildings. What Is the Portfolio Manager? The Portfolio Manager is an interactive energy management tool that allows tracking and assessment of energy consumption across an entire portfolio of buildings in a secure online environment. It can be used to identify under-performing buildings, set capital improvement priorities, verify efficiency improvements, and identify successful energy management practices in state facilities. What Are the Benefits of Benchmarking and Monitoring Building Energy Use? Studies have shown that metering, recording and monitoring the energy use of a building reduces energy use. The scores provided by Portfolio Manager for rated building types can be used to set goals for a portfolio of buildings. Buildings that get the Energy Star rating perform better than 75 percent of similar buildings, and use 35 percent less energy than the average building of that type. Buildings that get the Energy Star must also meet or exceed American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. standards for comfort and air quality. Setting a goal for all K-12 schools to get the Energy Star would not only save energy, but would provide documentation
