The IGCC will reference the Public Version 1.0/ ANSI/ASHRAE/USGBC/IES Standard 189.1-2009 for the Design of High-Performance Green Buildings, Except Low-Rise Residential Buildings, as an alternative jurisdictional compliance option within the IGCC. The participants in designing this Standard also voiced their support for the new IGCC and its ...
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 ...
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).

ASHRAE's Standard 55-2017 has minimum standards of 8.3 L/s/person. In one study, raising the rate to 15 L/s/person increased performance by 1.1% and decreased sick building symptoms by 18.8%. [ 12 ] Whole Building Design Guide recommends separating ventilation from thermal conditioning so as to increase comfort.
Some energy standards are written in a mandatory and enforceable language, making it simple for governments to add the standards' provisions directly to their laws or regulations. The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) is a well-known example of a standard-making organization.
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.
The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls.

This project linking all computers and workstations on campus set the standard for educational computing and established Carnegie Mellon as a technology leader in education and research. On April 24, 1985, cmu.edu, Carnegie Mellon's Internet domain, became one of the first six.edu domain names.
