ASHRAE Membership ASHRAE membership is open to any person associated with heating, ventilation, air conditioning or refrigeration. ASHRAE is unique because its membership is drawn from a wide range of disciplines relating to the HVAC&R field.

Over 56,000 individuals from more than 100 nations belong to the Society. Discounts on Publications ASHRAE members earn 15% off publications. Hundreds of titles are available including the complete collection of ASHRAE Standards including 90.1, 62.1 and 189.1.

Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years. This standard provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings. It offers, in detail, the minimum energy efficiency requirements for design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as criteria for determining compliance with these requirements.

It is an indispensable reference for engineers and other professionals involved in design of buildings and building systems. This 2016 edition comprises numerous energy-saving measures and incorporates changes from more than 125 addenda.

It also includes the following: Format changes to improve usability and readability: • One-column format for easier reading • Exceptions separated, indented, and set apart with a smaller font size • Italicized defined terms • Changes to table formats to provide contrast between rows Structural changes: • A new Reference Standard Reproduction Annex 1 is provided at the end of the document. Section 5.1.4 now cites ASHRAE Standard 169 as the source for climatic data, and Annex 1 contains extracts of tables and figures from that standard for the reader’s convenience.

• Two new climate zones (0A/B) have been added to all prescriptive requirements tables. Significant technical content changes: Building Envelope • Envelope verification in support of reduced air infiltration and increased requirements for air leakage of overhead coiling doors. • Increased stringency requirements for metal building roofs and walls, fenestration, and opaque doors. • Improved clarity on defining exterior walls, building orientation, fault assumptions for the effective R-value of air spaces, and calculation procedures for insulating metal building walls. Diver T Program Dallas County Records. Lighting • Modified requirements for exterior and interior lighting power densities to reflect new lighting levels in the IES Lighting Handbook. • Modified requirements for lighting control to add additional controls in some space types and options to others to allow easier application of advanced controls.
