Overview
Project Objectives:

 NEEA is partnering with the Northeast Energy Efficiency Partnership (NEEP) to integrate our VHE-DOAS into a DOE funded project that aims to validate VRF performance in cold climates. The project’s main objectives are:

A) To generate and assess high quality observed in-field data on variable refrigerant flow (VRF) actual energy performance and refrigerant leakage.

B) To effectively communicate these results to key audiences that directly impact heating, ventilation and air conditioning (HVAC) technology selection in commercial institutional and multifamily buildings (i.e., building engineers, large commercial building developers, state/local housing agencies, municipalities, program administrators, etc.)

NEEA is currently recruiting existing VHE-DOAS installations which utilize VRF as the heating/cooling system in "colder" areas of our region. This includes sites east of the cascade mountain range.

Current Project Phase: Active
Current Project Status: NEEP's RFP has been revised based on feedback from the RFI respondents as well as the manufacturers they are partnering with. NEEP has come up with some creative ways to measure refrigerant leakage that does not require a full HVAC system shutdown for multiple days. This reduced burden on the building owners should help to aid in the recruitment of 5 sites for participation in this study.
