An enhanced electronic version, known as ASHRAE Handbook Online is a web-based version updated annually that contains the four latest volumes as well as extra content such as calculations, demonstration videos, and spreadsheets. The various versions of the Handbook are typically available to the public via technical, and other, libraries and ...
ANSI/ASHRAE Standard 55 was first published in 1966. It was revised in 1974, 1981, 1992, 2004, 2010, 2013, 2017, 2020 and 2023. Starting in 2004, it is now updated based on ASHRAE's standard maintenance procedures. These periodic revisions are based on a publicly reviewed addenda to the previous version available on ASHRAE's website. [13]
ANSI/ASHRAE/IES Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings is an American National Standards Institute (ANSI) standard published by ASHRAE and jointly sponsored by the Illuminating Engineering Society (IES) that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings (i.e. single-family homes ...
[4] The model code, IECC, and the standard, ASHRAE 90.1, apply to commercial buildings. [5] [4] [6] The IECC references several ASHRAE Standards, in particular, ASHRAE 90.1 for commercial building construction. [22] Being a part of the ICC’s collection of model codes, the IECC is revised annually and published in full-form every three years.
Air filtration standards differ between the U.S. and other countries. The American ASHRAE rating system does not account for changes in filtration efficiency due to electrostatic charge. These MERV ratings do not account for a decrease in efficiency over the first few weeks of use due to a drop in static charge.
Minimum Efficiency Reporting Value, commonly known as MERV, is a measurement scale designed in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers to report the effectiveness of air filters in more detail than other ratings.
ASHRAE was founded in 1894 at a meeting of engineers in New York City, formerly headquartered at 345 East 47th Street, and has held an annual meeting since 1895. [4] Until 1954 it was known as the American Society of Heating and Ventilating Engineers (ASHVE); in that year it changed its name to the American Society of Heating and Air-Conditioning Engineers (ASHAE).

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) provides lighting standards in ASHRAE 90.1-2004. EPAct of 2005 set a deadline for states to adopt the ASHRAE 90.1-2004 standards. [19] ASHRAE has recently published the 90.1-2010 with improved lighting standards, this includes:
