This Guide explains how to commission ducted air distribution systems in buildings. The commissioning process mainly comprises the setting to
work of the system fans and the regulation (or proportional balancing) of system flow rates. The procedures set out in this guide, if undertaken, should achieve compliance with the requirements of CIBSE Code A Air Distribution Systems. In general, CIBSE Code A sets out the normal standards of good practice which are generally accepted within the building services industry.
This guide explains how to carry out the commissioning procedure in a way that ensures these standards are achieved. This guide is equally applicable to new-build and retrofit large scale commercial applications. The procedures are not generally applicable to ventilation systems in dwellings. For domestic applications, reference should be made to BSRIA publication BG46/2013 Domestic ventilation systems – a guide to measuring air flow rates
