ASHRAE’S FIRST RESIDENTIAL VENTILATION STANDARD1 Fellow ASHRAE ABSTRACT ASHRAE has recently published its first residential ventilation standard, Standard 62.2-2003. This standard 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. The Example calculation to test the rule of thumb for 5% natural ventilation area The design formulae in CIBSE Guide A and CIBSE Guide AM10 have been used to test a 15 m wide floor plate with 5% ventilation openings distributed evenly on opposite facades and at high and low levels – refer to Figure 1.

    ASHRAE Standard 62.1 is a guideline to follow for improving the indoor air quality in a building through ventilation to make it acceptable for people occupying the building and to minimize health effects. Section 5 is based on the buildings systems and equipment that make the indoor air quality. 5.1 Natural Ventilation Table 6-2 in standard 62.1 include Ez values based on how well a ventilation supply delivers air into the breathing zone. As I recall, although it is not in ASHRAE 62.1, the Ez of 0.8 in the table is based on a 40 fpm (feet per minute) supply "jet" of air.

In the event of a spill, a displacement ventilation system is likely to cause noxious fumes to be drawn from the floor and brought up to the breathing level, thereby increasing the possible hazard to occupants.

Gene Tucker, Chairman ASHRAE SSPC62 Air and Energy Engineering Research Laboratory U.S. Environmental Protection Agency Research Triangle Park, North Carolina, USA ABSTRACT This paper briefly describes the purpose, history, and major features of HVAC – NATURAL VENTILATION PRINCIPLES AND PRACTICES . Natural ventilation, as the name implies, is a system using natural forces to supply fresh air for comfort and heat dissipation. As an alternative to mechanical (fan-forced) ventilation, this approach relies on the natural forces of wind and buoyancy to deliver fresh air to indoor spaces. Natural ventilation may be divided into two
