New CIBSE Guide B2: Ventilation and Ductwork

This recently released volume, is part of “CIBSE Guide B: Heating, Ventilating, Air Conditioning and Refrigeration”, providing guidance on the practical design of heating, ventilation and air conditioning (HVAC) systems. The guide, released by the Chartered Institution of Building Services Engineers (CIBSE), was published in five separate chapters.

The specific chapter:

  • sets out the criteria for the design of ventilation systems covering the contribution of ventilation to providing a safe and comfortable indoor environment, including indoor air quality, thermal comfort and noise;
  • reviews the principal methods of providing ventilation and describes the basic principles of related systems for air distribution, filtration, heat recovery and control;
  • sets out the principles for designing natural, mechanical and mixed-mode systems and includes the design of ductwork, calculation techniques and methods of measuring the performance of ventilation systems;
  • discusses other design considerations closely related to ventilation and covers noise, air leakage, fire and smoke protection;
  • covers the components of a ventilation system and includes fans, air control units, mixing boxes, terminal devices, extract hoods and duct equipment. Also included is equipment for natural ventilation;
  • covers the important areas of testing, commissioning, maintenance and cleaning.
