Abstract
According to UK Building Regulations, Approved Document F, published in
2006, ventilation system effectiveness can range from zero (complete short
circuiting) to infinity (perfect displacement/piston). The rate of supply of fresh
air required to achieve a particular air quality is directly related to ventilation
effectiveness; the greater the effectiveness, the less fresh air required. At a time
of heightened awareness of the need for carbon reduction measures, this must be
of interest to designers of ventilation systems. The volume of fresh air required
impacts on energy use in two ways: firstly in terms of the electrical energy to
move the volume of air through the building (fan power), and secondly in terms
of energy to condition the air (heating or cooling). In the course of performance
testing ventilation systems designed to control environmental tobacco smoke, the
authors have examined the performance of a number of different techniques.
This paper reports on some of the better techniques observed, which may prove
useful in other applications, both in terms of improving the control of indoor air
quality and also in reducing carbon impact in achieving that air quality.
Keywords: fabric diffusers, ventilation, indoor air quality (IAQ), energy
performance.
1 Introduction
The impact of indoor air quality on energy performance is acknowledged in BS
EN 15251 [1], Indoor environmental parameters for design and assessment of
energy performance of buildings addressing indoor air quality, thermal
environment, lighting and acoustics. This standard has been developed to
harmonise an energy performance of buildings calculation methodology to meet
the requirements of the Energy Performance of Buildings Directive. UK
