This study focuses on the way to apply CEN test methods to a full range of air diffusers and is dedicated to the improvement of these methods proposed by the CEN TC l 56/WG4 of which both authors are members. Air terminals of different sizes have been tested on aerodynamic and acoustic aspects both in a Spanish and a French laboratory. The tests were made according to pr EN 12238 ''Air Terminal devices - Aerodynamic testing and rating for mixed flow applications" and to EN 25135 (ISO 5135).

The BR E has developed a set of computer-based tools for the management of heating, ventilating and air conditioning systems. How can designers and facilities managers use them to improve the performance of buildings?

Developed by Conserval Engineering of Toronto, Canada, the Solarwall™ is a solar system for heating ventilation air for buildings. The Solarwall looks like conventional metal cladding, but performs like a solar panel.Matrix Energy Inc. of Montreal, in partnership with Conserval, installed the Solarwall system at Bombardier's Canadair facility in Montreal, Quebec. The installation paid for itself in energy savings in just 1.7 years, and allowed the company to stop using fossil fuels, with their associated emissions.

This Technical Report has been prepared by Technical Committee CEN/fC 1 56, Ventilation for buildings. This Technical Report is intended to assist in providing an acceptable indoor environment for people in ventilated buildings.This Technical Report specifies the requirements for, and methods of expressing the quality of the indoor environment for the design, collllllissioning, operation and control of ventilation and airconditioning systems. This Technical Report covers indoor environments where the major concern is the hwnan occupation but excludes dwellings.
