ASHRAE Standard 62.1-2016 – Summary of significant changes. The 2016 update to ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality, has changes that affect the indoor air quality procedure, laboratory exhaust and demand control ventilation. The standard sets minimum ventilation rates and other requirements for commercial.

It will also include some overall background on the standard and its overall impact on Building Energy Efficiency and Design.
ANSI/ASHRAE/IES Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings is an published by and jointly sponsored by the that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings (i.e., less than four storeys high, and ). The original standard, ASHRAE 90, was published in 1975. There have been multiple editions to it since. In 1999 the ASHRAE Board of Directors voted to place the standard on continuous maintenance, based on rapid changes in energy technology and energy prices. This allows it to be updated multiple times in a year. The standard was renamed ASHRAE 90.1 in 2001.
It has since been updated in 2004, 2007, 2010, 2013 and 2016 to reflect newer and more efficient technologies. Contents.Structure and form In general, there are two means, or paths for building designers to comply with ASHRAE 90.1:. Prescriptive path: All components of the building meet the minimum standards specified by ASHRAE 90.1.

Performance path: A proposed building design is demonstrated (through ) to use less energy than a baseline building built to ASHRAE 90.1 specifications. This now has three paths. For code compliance there is Chapter 11, which compares an energy model for your building to an energy model for a barely compliant building with the same HVAC system and in the 2016 edition an Appendix G path was added that compares an energy model of your building against a baseline model based on the 2004 edition of Standard 90.1 and requires lower energy consumption that varies depending on the building type.Within the sections of the standard, there are some variations to this. ^ American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc.
