Standardisation in the field of industrial air technology.

Standards dealing with Industrial Air Technology (IA T) are very fragmented, and a real need exists for new standards this very important field. These are required to facilitate trade and communication in this important area. Clarification of the requirements for these proposed standards is necessary before any new technical committee (TC) can be established, or before new work could be allocated to any existing TC. Since 1996, there has been little discussion about new activities, a few work items on related subjects have however commenced under existing Technical Committees.

ASHRAE to lower mechanical ventilation requirement in 62.2P.


ASHRAE's residential ventilation standard: Exegesis of proposed standard 62.2.

In June 2000 ASHRAE's Standard Project Committee on "Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings", SPC 62.2P, recommended and the Board of Directors approved ASHRAE's first complete standard on residential ventilation for public review. The standard is an attempt by the Society to address concerns over indoor air quality in dwellings and to set minimum requirements that would allow for indoor air quality and energy efficiency measures to be evaluated.

Indoor environment and air quality.

Guidelines for comfort.

ASHRAE Standard 55-1992, Thermal Environmental Conditions for Human Occupancy, is mainly a prescriptive standard intended for occupants with primarily sedentary activity. This article discusses some of the issues being addressed during the proposed revision. The proposed revision will include an analytical method based on the PMVPPD method, where different levels of comfort may be specified. Using the analytical method requires better dialog between the client (builder, owner) and the designer.
