New Commissioning Air Systems guideJuly 2013

This new guide (BG49/2013) now replaces Commissioning Air Systems (AG 3/89.3) and Commissioning of VAV systems in buildings (AG 1/91). It 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.

A new edition of Commissioning Air Systems has been published for several reasons. Amendments to Part F and Part L of the Building Regulations require newly installed ventilation systems to comply with new standards and that reasonable provision for commissioning be made in order that systems don’t use too much fuel or power. Environmental assessment methods such as BREEAM, LEED and DREAM have focused the minds of building owners, operators, developers and designers on the benefits of a proficient, professional commissioning process. Technological advances in plant and equipment have also resulted in increasing importance being placed on commissioning.

This guide explains how to carry out procedures in order to comply with the standards outlined in CIBSE Commissioning Code A Air Distribution Systems (which sets out the normal standards of good practice accepted by the building services industry).

Chapters cover:

  • Design for commissionability
  • Commissioning facilities
  • The installation of commissionable systems
  • Site test instruments
  • On-site flow measurement techniques
  • Commissioning procedures
  • Example methods statements
  • Documentation (including editable proforma checklists in Excel)
