The first step to making a building more efficient is to understand how much energy it uses and how its usage compares with that of similar buildings. Therefore, the Greener, Greater Buildings Plan (GGBP) requires owners of large buildings to annually measure their energy consumption in a process called benchmarking. Local Law 84 (LL84), the first law in GGBP, standardizes this process and captures information with the U.S. Environmental Protection Agency's (EPA) free online benchmarking tool called Portfolio Manager. LL84 will give building owners and potential buyers a better understanding of a building's energy and water consumption, eventually shifting the market towards increasingly efficient, high-performing buildings.
In summary, LL84's annual benchmarking process requires the following:
- Determine if a building needs to be benchmarked.
- Measure the building's energy and water use with an online benchmarking tool.
- Submit usage data online annually to the City by May 1.*
* ENERGY STAR Portfolio Manager, the online tool used to comply with LL84, was offline from Monday April 29 through Monday May 6 with technical issues. The City recognized the impact this had on meeting the May 1st deadline, and therefore issued an official deadline extension to May 31, 2013.
The next deadline is November 30, 2013. If you have not submitted your 2012 benchmarking report, be sure to submit by this next deadline to avoid a possible violation and $500 fine. Find more information in the section "How to Comply."
