This measure is the installation of a new high efficiency single speed or dual speed central air conditioner. Per the Council’s Northwest Regional Cost-Effectiveness test this measure is not cost-effective, primarily because the energy savings occur in the summer and therefore do not align with the regional winter peak or get the benefit of deferred generation. However, for summer peaking utilities, this measure might have greater value. At adoption, the RTF set the measure to Planning as there remains uncertainty around regional cooling loads and the relationship between SEER and EER and energy usage in the Pacific Northwest. RTF Staff has developed a Research Strategy to target this uncertainty.
