Use this section to enter benchmark and target site energy use and cost inputs per ASHRAE level 2 guidelines. Begin by selecting the source of the benchmarking data from drop down menu of options. In accordance to Standard 211P, the benchmark sources may be any of the options listed in the drop down menu. Selected city reports may include a field to include a source if ‘Other’ was selected from the drop down, and/or a field to include an Energy Star Portfolio Manager (ESPM) ID if ESPM was selected from the drop down.
Enter the year used for the benchmarking data, and values for site energy use intensity and site energy cost intensity for the benchmark building. Then enter target values for site energy use intensity (EUI) and site energy cost intensity. The definition of building use and floor area should be consistent for this comparison.
An estimate of the annual energy and cost savings that would be achieved if the target EUI and cost intensity is met will be automatically displayed. These values will be calculated as follows:
- Annual Energy Savings to Reach Target (kBtu) = (Benchmark Site Energy Use Intensity - Target Site Energy Use Intensity) / Gross Floor Area
- Annual Cost Savings to Reach Target (kBtu) = (Benchmark Site Energy Cost Intensity - Target Site Energy Cost Intensity) / Gross Floor Area
Selected city reports may include additional fields in this section, including principal use type, ESPM rating, weather normalized eui, GHG emissions, and water use intensity.
