Guide B provides guidance on the practical design of heating, ventilation and air conditioning systems and is divided into six sections which are published separately:
- B0: Applications and activities
- B1: Heating
- B2: Ventilation and ductwork
- B3: Air conditioning and refrigeration
- B4: Noise and vibration control for building services systems
- Guide B Combined index
The full set is available at a discounted price here: Guide B (full set)
Guide B1: Heating deals with the selection, design, commissioning, operation and management of most types of heating systems in buildings. It deals specifically with non-domestic buildings, though much of the contents will apply to domestic communal heating. Such systems provide space (including ventilation) heating and/or hot water services and installations such as swimming pools. Virtually every building (outside the tropics), contains a heating system. In most cases its primary purpose is to produce acceptable levels of thermal comfort – paramount for the health and wellbeing of building occupants and provide domestic hot water – or to protect the building fabric or its contents.
Topics covered include:
- Strategic design decisions
- Purposes of heating systems
- External design conditions
- Site related issues
- Interaction with building design, fabric, services and facilities
