IGEM/G/5 Edition 3 - Gas in multi-occupancy buildings - Hard copy

This standard covers gas installations to and within multi-occupancy buildings and the individual dwellings and commercial units within such buildings. It does not cover installations to and within properties considered separate buildings, each comprising a single dwelling, such as detached, semi detached or terraced houses/bungalows.

It includes details on the installation of:

• Pipelines both external and internal to the property, and within individual dwellings, along with the method of entry into the property
• Individual meters for individual dwellings, meter banks or primary meters serving multiple individual dwellings
• Various isolation valves, both external and internal to the property, to allow potential gas escapes to be removed and controlled
• Central facilities that generate heat or heat and power from a boiler or engine installation, known as energy centres (generally industrial or commercial in nature)
• Chimneys
• Gas appliances (and their selection) within individual dwellings.
