Field Test for RTU Replacements which include VCHP + HRV+ DOAS in Commercial applications

The goal of this grant is to share the cost for the design, installation, and commissioning to replace Roof Top Units (RTU) with Heat Recovery Ventilation (HRV) and Variable Capacity Heat Pump (VCHP) systems. In 2016, Northwest Energy Efficiency Alliance (NEEA) identified this potential RTU replacement strategy to help meet the regions energy efficiency targets and conducted a proof of concept study for this new replacement system. NEEAs preliminary analysis estimates that an HRV and VC HP system could be combined to save over seventy percent of the energy used by RTUs. BPA is interested in obtaining field data for additional systems in the Pacific Northwest. The expected results from this project include the following: HRV and VC HP system cost effectiveness information; System performance data; Verification that whole-building billing analysis is an adequate methodology to measure savings, and Identification of best practices for installation and commissioning based on feedback from the owner, utility, designer, contractor and occupants.
