  2. ASHRAE Handbook - Wikipedia

    en.wikipedia.org/wiki/ASHRAE_Handbook

    The ASHRAE Handbook is the four-volume flagship publication of the nonprofit technical organization ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers [a]). This Handbook is considered the most comprehensive and authoritative repository of practical knowledge on the various topics that form the field of heating ...

  3. Cooling load temperature difference calculation method

    en.wikipedia.org/wiki/Cooling_load_temperature...

    The CLTD/CLF/SCL (cooling load temperature difference/cooling load factor/solar cooling load factor) cooling load calculation method was first introduced in the 1979 ASHRAE Cooling and Heating Load Manual (GRP-158) [1] The CLTD/CLF/SCL Method is regarded as a reasonably accurate approximation of the total heat gains through a building envelope ...

    en.wikipedia.org/wiki/ASHRAE_90.1

    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.

  6. ASHRAE - Wikipedia

    en.wikipedia.org/wiki/ASHRAE

    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).

  7. ASHRAE 55 - Wikipedia

    en.wikipedia.org/wiki/ASHRAE_55

    ANSI/ASHRAE Standard 55: Thermal Environmental Conditions for Human Occupancy is an American National Standard published by ASHRAE that establishes the ranges of indoor environmental conditions to achieve acceptable thermal comfort for occupants of buildings. It was first published in 1966, and since 2004 has been updated every three to six years.

  8. Air filtration in operating rooms - Wikipedia

    en.wikipedia.org/wiki/Air_filtration_in...

    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.

  9. Air changes per hour - Wikipedia

    en.wikipedia.org/wiki/Air_changes_per_hour

    Air changes per hour is a measurement intended to communicate the air change effectiveness of a space’s ventilation system. Discussion around the ASHRAE standard 62, Ventilation for Acceptable Indoor Air Quality led to the development of a more direct method of measuring air change effectiveness with the use of a tracer gas.
