Property owners in California are now required to benchmark every commercial and multi-family (+17 units) building over 50,000 square feet. Other cities have more stringent requirements like benchmarking down to 10,000 square feet and some even require benchmarking water usage. While these requirements will certainly require effort, the good news is a benchmark can happen in two hours or less if you have your building information is ready.
In most cases the difficult part of benchmarking is collecting your energy data. Utilities typically have tools to make this easier and in most cases your account rep can help. EnergyStar’s Portfolio Manager requires information on square footage and space use but nothing really technical.
