LL84 Made Easy 

The is a lot of confusion out there about the requirements of Local Law 84 and we thought it would be useful to share a few tips to save building owners and managers time. Our clients are mostly multifamily properties so these tips are somewhat tailored towards them.  

  1. Find out which of your buildings need to comply with the law. This pdf is an exhaustive list of all properties that need to benchmark their energy use. If you know your building's block and lot number you should be able to find them. In addition, take note of the square footage all the way in the right most column. This is the number the city currently has on file but it may be wrong. To ensure that your are getting the most accurate benchmarks use the correct square footage of your building when you enter it in Portfolio Manager.
  2. Send out this form to all separately metered non-residential tenants right away. Sending this form to all non-residential tenants that pay their own electric or gas bill, even if they don't respond, is a requirement of the law.
  3. Make a data collection plan. The trickiest part of complying with local law 84 is obtaining all the electric and gas data you need for your building. There are three ways to to get the data (but you will probably use a combination of the three):
    • If you have account numbers you can get the data directly from the Con Edison or National Grid website. Alternatively, you can use WegoWise to help you gather the data from the utility websites.
    • You can request aggregate whole building data from both ConEd and National Grid but there is a charge of $102.50 per building. This process takes a few weeks so make sure to plan ahead. Also, in our experience the spreadsheets the utilities send are difficult to work with and rarely report all the meters for every month. Which leads us to the last way to get data, estimation.
    • You can estimate usage in two ways. If you need to estimate a large number of residential accounts you can collect data for 10% of the apartments and then use an average to fill in the rest. This is very useful for filling in the gaps in ConEd or National Grid aggregate data. The second way to estimate is using default values provided by the city for commercial tenants and residents. Here is a document that goes into more detail about default values and formulas for estimating data. Pages five through seven give you all the information you need to estimate usage data.
