Requirements for the design of energy-efficient buildings.

Like all ASHRAE standards, 90.1 and 90.2 are consensus standards that provide minimum The energy-efficiency standards are ASHRAE 90.1 (see Figure 1) and ASHRAE 90.2 (see Figure 2). ASHRAE has some 87 active standards and guideline project committees, addressing such broad areas as indoor air quality, thermal comfort, energy conservation in buildings, reducing refrigerant emissions, and the designation and safety classification of refrigerants. ASHRAE standards and guidelines include uniform methods of testing for rating purposes, recommended practices in designing and installing equipment, and other information to guide the industry. ASHRAE Standard 90.1 and Other GuidelinesĪSHRAE writes standards and guidelines in its fields of expertise to guide industry in the delivery of goods and services to the public.

ASHRAE offers resources to the insulation industry via several formats: energy standards, handbooks, technical committees, programs and symposiums, and professional development.
