Content DescriptionIncreased Mechanical Ventilation Rates and More in Standard 62.2-2013 For the 2013 edition of ANSI/ASHRAE Standard 62.2, mechanical ventilation rates have been increased to reflect the elimination of the default assumption of a leakage rate of 2 cfm per 100 ft2. Other significant changes were made regarding climate limitations on pressurization and depressurization, carbon monoxide alarms, and calculations and weather data for estimating annual leakage. In total, this 2013 edition incorporates the contents of 17 addenda into the 2010 edition. Standard 62.2 defines the roles of and minimum requirements for mechanical and natural ventilation systems and the building envelope intended to provide acceptable indoor air quality in low-rise residential buildings. As in the previous editions of this standard, there are three primary sets of requirements and a number of secondary ones. The three primary sets involve whole-building ventilation, local demand-controlled exhaust, and source control. The secondary requirements focus on properties of specific items needed to achieve the main objectives of the standard. Standard 62.2 applies to spaces intended for human occupancy within single-family houses and multi-family structures of three stories or fewer above grade, including manufactured and modular houses. This standard does not apply to transient housing such as hotels, motels, nursing homes, dormitories, or jails. The standard considers chemical, physical, and biological contaminants that can affect air quality. It does not address thermal comfort requirements, specific pollutant concentration levels, or certain potential pollutant sources such as unvented combustion space heaters and contamination from outdoor sources or from episodic occupant-controlled events such as painting, smoking, cleaning, or other high-polluting events. The PDF download of Standard 62.2, in addition to offering immediate access to the content, presents the climate zone map in color for enhanced readability.This book also exists in the following packages...Subscription InformationMADCAD.com ASHRAE subscriptions are annual and access is concurrency based (number of people that can access the subscription at any given time).

About ASHRAEASHRAE, founded in 1894, is a building technology society with more than 50,000 members worldwide. The Society and its members focus on building systems, energy efficiency, indoor air quality and sustainability within the industry. Through research, standards writing, publishing and continuing education, ASHRAE shapes tomorrow’s built environment today.
ASHRAE was formed as the American Society of Heating, Refrigerating and Air-Conditioning Engineers by the merger in 1959 of American Society of Heating and Air-Conditioning Engineers (ASHAE) founded in 1894 and The American Society of Refrigerating Engineers (ASRE) founded in 1904.
