Building RegulationsServices: Building Regulations Part L - Design & Compliance
| Technical Guidance Document Part L (TGDL) is the part of the Building Regulations that deals with the conservation of fuel and power. Recent releases of TGDL include 2002, 2005 and 2007. TGDL 2002 was 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 TGDL have increased in complexity. TGDL 2007 requires a detailed analysis of predicted building performance to ensure characteristics of the building fall within limiters regarding energy consumption, carbon emissions and the use of renewable energies. In TGDL 2007, the main tool used to show compliance is the Dwellings Energy Assessment Procedure (DEAP) as used for energy ratings (BERs). |  Â |
SES 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, TGDL compliance is often carried out as a package service with BER certification.
Detailed information on compliance can be obtained by downloading the technical guidance documents from http://www.environ.ie. TGDL is one of several technical guidance documents ranging from A to M. TGDF (Ventilation) and TGDJ (Heat Producing Appliances are also important documents in relation to the thermal performance of buildings.
