Part L2a & L2b Compliance

Part L - Increasing the efficiency of tomorrow's buildings

Part L compliance testing is required for all new builds, the test is a move to ensure the buildings of the future use less carbon. This is achieved by ensuring:

  • Buildings should be designed and constructed to conserve fuels and power so as to minimise CO2 emissions related to the building’s operation.
  • Buildings should be designed and constructed to minimise heat loss and heat gain through the building fabric and building services distribution.
  • Buildings should be designed and constructed to avoid excessive solar gain and to reduce requirements for artificial cooling.
  • It must be demonstrated that the requirements have been met though approved calculation methodologies, pressure tests and results of testing and commissioning.
  • Appropriate operation and maintenance manuals are required so that no more carbon emissions than are reasonable occur in use.

Part L will affect all aspects of the building design. It allows flexibility in design and there are no prescriptive requirements, only some minimum standards. So, in addition to insulation levels, proportion and type of glazing, other factors that may be improved are:

  • Shading, such as external shading, double wall facades
  • Boiler efficiencies and chiller co-efficients of performance
  • Building envelope airtightness
  • Lighting efficiency and control
  • Fan and pump efficiencies, air and water pressure drops
  • Heat recovery.

At footPRINT we understand that although many architects will be aware of the above some may have limited experience in which case we are at hand to help work through the process. We also offer advice on government funding schemes in aiding the up take of energy saving technologies.
We prefer using CAD files where possible in order to obtain the highest degree of accuracy, but will also except physical plans.
