This new edition of BG 31 comes nine years after the previous guide and reflects significant changes in regulation and technology over that period. Changes to Part L have increased the focus on energy performance and higher-efficiency building services, while heat pumps and heat networks are playing a growing role in how buildings are heated. Fire safety also remains a key consideration in the design and installation of mechanical services.
This guide provides basic reference information on mechanical building services systems for construction clients and professionals in other areas of the construction industry.
This guide covers the key areas of heating, ventilation, air conditioning and controls and since the previous edition of this guide, information has been added on heat pumps and heat networks.
For construction clients, the guide provides a simple insight into the main system options discussed during the briefing process. It can also help clients to identify and raise technical questions which they feel are relevant to their organisation's specific needs. For construction professionals, the guide provides a quick reference to building services systems.
To ensure the guide is simple and quick to use, a brief overview of each system is provided, followed by a list of key points. Photographs and simple drawings are used to help explain the appearance and operation of each system.
