Frequently Asked Questions

What are RTEM Qualified Vendors?

NYSERDA has 120 RTEM Qualified Vendors who are experts in delivering the highest-quality RTEM service for residential spaces. Our partnered vendors offer advice and support throughout the project—from installation to continued monitoring and optimization.

Since 2017, NYSERDA has supported the installation of RTEM platforms in over 1,200 buildings – including 300+ Multifamily sites – representing nearly 300 million square feet of property in New York.

As a key condition of participation in the program, NYSERDA required that vendors were qualified through a rigorous, independent review process, which stress-tested claimed system capabilities and features, along with a vendor’s documented track record of performance on previous projects. While over 450+ vendor applications were evaluated over the course of the program, the NYSERDA team found that only ~125 met the minimum set of required functionality and service reporting standards.

Amongst these vendors, NYSERDA issued two types of qualification: System and Service

System Vendors: Responsible for the underlying data collection and control platform – the hardware & software located within the four walls of your building connected to equipment which extracts the real-time data and makes it available, along with automatic insights, in the cloud.

Service Vendors: Experienced with analyzing real-time data from RTEM Systems and working to optimize building system operation.  Responsible for generating an in-depth set of insights on equipment operation on a recurring basis to drive adoption of data-based Energy Conservation measures.

The qualified vendors offer advice and support throughout the project — from installation to ongoing monitoring and optimization. While all vendors have met the same minimum bar for qualification, some System or Service offerings may be more or less applicable to your specific building type or systems.

If you have questions on which of the companies on our Qualified Vendor list may be a best fit for your facility type or equipment, we encourage you to reach out to us through the link above and we can help generate options!

What is Local Law 97?

Local Law 97 (LL97) is part of New York City’s ambitious plan to address carbon emissions and make NYC carbon neutral by 2050. Once enacted, most buildings over 25,000 gross square feet that exceed emissions limits will face annual fines beginning in 2025.
