Advanced Rooftop Controls (ARC) Verification Protocol

The goal is to develop a standard protocol to verify site-based savings for advanced rooftop unit (RTU) control (ARC) retrofits, based on manufacturer variable frequency drive (VFD) data. This will streamline the acquisition of 1 aMW of ARC retrofits and lower the cost of the impact evaluation. This project will draft a standard protocol to verify ARC retrofit site-based savings using Catalyst controller data. The project will compare best practice (unit-level, true-power over one-year with daily baseline cycling, as reported in Pacific Northwest National Laboratory (PNNL) study) and four simplified savings methods, to determine a simplest-reliable method. Deliverables include a draft protocol and presentations to the RTUG and, if appropriate, to the RTF. Once approved, the standard protocol would allow the streamlined acquisition of ARC retrofits because baseline metering and long-term baseline cycling would not be required. Once 1 aMW of ARC retrofits (approximately 1,000 RTUs) are reported, several years of Catalyst controller data would be available for most of the units for the impact evaluation. Using the standard protocol and manufacturer data, no post-post cycling or additional instrumentation, such as Wattnodes for unit-level true-power, will be required.
