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 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).

The thermal insulation requirements in the USA follow the ASHRAE 90.1 which is the U.S. energy standard for all commercial and some residential buildings. [13] ASHRAE 90.1 standard considers multiple perspectives such as prescriptive, building envelope types and energy cost budget.
A module for Appendix G of ASHRAE 90.1-2010 is available, this is used for example in LEED and BREEAM. The integrated radiosity method with single reflection and one measuring point can be used for whole-year daylight analysis and allows modeling daylight-based control strategies (e.g. shading devices, artificial lightening).
Building performance simulation model with input and some resulting output. Building performance simulation (BPS) is the replication of aspects of building performance using a computer-based, mathematical model created on the basis of fundamental physical principles and sound engineering practice.
Modern revolving doors permit the individual doors of the assembly to be unlocked from the central shaft to permit free flowing traffic in both directions. This feature, called breakout or break away, is typically used only during emergencies, or to admit oversize objects. The most effective method for this is the "bookfold" design, which ...
