With each new edition of ANSI/ASHRAE/IES Standard 90.1, DOE is required by statute [8] to issue a determination as to whether the updated edition will improve energy efficiency in commercial buildings. DOE issued a positive determination stating that Standard 90.1-2013 would achieve greater energy efficiency in buildings subject to that code ...
ASHRAE 90.1 follows a similar path of development and revision. [6] Though ASHRAE 90.1 is revised and published every three years just like the IECC, people can submit interim revisions at any time within this period. [5] ASHRAE has a standards committee that manages the process, and votes on the final versions of the energy code. [5]
There are two major systems to classify ductwork airtightness, one based on European standards, the other based on ASHRAE standard 90.1-2010.Both are based on the leakage airflow rate at a given ductwork pressure divided by the product of the ductwork surface area and the same ductwork pressure raised to the power 0.65.
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).

Space By Space Method. A defined list of many possible space types within a building the associated watts per square foot allowance. For example, ANSI/ASHRAE/IESNA Standard 90.1-2007 allows the Emergency Space of a hospital to be designed for 2.7 watts per square foot, but the Recovery areas of a hospital would be allowed 0.8 watts per square foot.
As such these design curves still form the basis of the target leakage rates for revolving doors recommended by the ASHRAE standard 90.1 in the US. [23] On May 25, 2006, an MIT Study entitled "Modifying Habits Towards Sustainability : A Study of Revolving Doors Usage on the MIT Campus" was published.
In October 2013, the United States ... In Climate Zones 4 and above the recommendation is to follow the ASHRAE 90.1 standard for roof reflectance, which does not ...
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:
