Overview

The general objective of the annex was to develop methods to minimize energy consumption of large enclosures in the provision of:

  • good indoor air quality and comfort
  • the safe removal of airborne contaminants and
  • the satisfactory distribution of fresh air

The specific objective was to develop the following methods:

  • Analysis Methods to measure or model air motion, thermal stratification, and contaminant spread in given enclosed spaces and to evaluate performance and locate problems. The results are primarily addressed to HVAC specialists and researchers.
  • Design Methods which show how energy efficient ventilation may be achieved in new designs or in existing buildings (retrofit).

These guidelines are primarily aimed at designers and HVAC engineers.
