Services: Building Regulations Part L - Design & Compliance

Technical Guidance Document Part L deals with the conservation of fuel and power. Earlier releases up until 2006 were reasonably straight forward and compliance could be shown in a relatively simple way through u-values and application of some basic principles regarding services. Subsequent releases of Part L have increased in complexity and require a detailed analysis of predicted building performance to ensure characteristics of the building fall within limiters regarding energy consumption and carbon emissions. Energy performance compliance of new buildings is shown through SAP analysis (new homes) and a Simplified Building Energy Model (SBEM) for non-domestic properties.

Carbon Tweleve are able to offer services to assess compliance and provide advice on meeting compliance as necessary. As assessing compliance is strongly related to energy rating procedures, Part L compliance is often carried out as a package service with SAP certification.

 

Detailed information on compliance can be obtained by downloading the technical guidance documents from The Planning Portal website. TGDL is one of several technical guidance documents ranging from A to P. Part F (Ventilation) and Part J (Heat Producing Appliances) are also important documents in relation to the thermal performance of buildings.
