ICOM Guideance Notes
ICOM has published information relating to Building Regulations Part L 2010.
The 2010 version of Part L of the Building Regulations is supported for buildings other than dwellings by Approved Documents ADL2A (new buildings) and ADL28 (existing buildings). These documents require new buildings and in some instances existing buildings, to be assessed for total annual energy usage and carbon emissions, using the National Calculation Methodology. They also specify the minimum acceptable performance for services such as heating and domestic hot water systems.
A summary of the minimum provisions for the following are detailed in our Key Account Bulletin No.15:
- Gas and Oil Fired Warm Air Heaters
- Gas & Oil Fired Water Heaters
- Gas & Oil Fired Radianty Heating Technology
- Boiler Systems
