Abstract

Commercial HVAC and service water-heating equipment efficiency is mandated in the U.S. through a strong linkage to ASHRAE Standard 90.1. ASHRAE recently updated Standard 90.1 in 1999, triggering rulemaking processes undertaken by the U.S. DOE to set mandated manufacturing minimum efficiency levels for covered equipment at Standard 90.1 levels or higher if technologically feasible and economically justified. This paper describes the history of this policy, current activities and decisions, and the technical, economic, and policy issues arising out of them.
