May 17, 2011 at 10:52 am Leave a comment

The Network has been looking into what it takes to comply with Local Law 84, a new NYC regulation requiring owners to benchmark their buildings that are over 50,000 square feet.  View our previous coverage of LL84 , or use the following list of resources to guide your benchmarking. We hope that our LL84 guide has been helpful to you, and we welcome your comments on how to improve it!



Covered buildings

Does LL84 apply to your building? Check the NYC Department of Finance website.

Finding your building’s block and lot number

You can find your building’s block and lot number on the NYC Dept. of Finance site

or by using NYC Dept of Buildings’ Building Information System (BIS).

Most, but not all buildings that have to comply with LL84 can also be found on NYC’s PlaNYC 2030 website.

LL84 Rules

On April 1, 2011, the city issued the final version of the rules for complying with LL84

Benchmarking on your own

Portfolio Manager

U.S. EPA’s Portfolio Manager is the tool used to benchmark buildings complying with LL84.

To comply with LL84, you must access the Portfolio Manager tool through a special portal on NYC Dept. of Building’s website.

Visit EPA’s webinar calendar for events that reference benchmarking and Portfolio Manager.

Sign up for AEA’s 3.5-hour benchmarking training course to walk through the Portfolio Manager tool with an instructor.
