Part L was updated in and then again in It focused initially on energy efficiency and then in on CO2. In the approved document was also divided into domestic and non-domestic sections — ADL1 and ADL2, respectively, and for non-domestic buildings a carbon performance calculation methodology was introduced, for those who wanted to adopt such an approach. This required EU member states to adopt a whole-building calculation method for assessing the carbon emissions of new buildings and gave them three years in which to do this.
And so the whole-building carbon emissions calculation became a requirement, not an option. In Part L underwent a revolution. To assist further, a domestic and non-domestic compliance guides were adopted, giving additional guidance on how to follow the new whole-building EPBD regime.
It is perhaps easy to forget that Part L was the biggest change to energy-conservation requirements in buildings in over 20 years and, arguably, the biggest single set of changes ever adopted in one set of regulations. At a stroke it did away with the elemental method beloved of many smaller builders, and brought in a small army of SAP assessors. It also introduced carbon-emissions targets for non-domestic buildings, rather than just energy-efficiency requirements.
Whilst it was adopted from the best of intentions, and to drive the uptake of such technologies, it had the unintended side effect that a building that met Part L by being a good passive building using less energy and emitting less carbon could still fall foul of planning.

Whilst there is no release date for new the Part L regulations, unless the consultation changes significantly, there is enough within the latest SAP 10 methodology to give an indication on compliance.
Reviewing the reference values used for the TER and the new TPER will assist developers, architects and energy assessors with understanding how compliance is achieved and where the short falls are within their specification. Summary Whilst there is no release date for new the Part L regulations, unless the consultation changes significantly, there is enough within the latest SAP 10 methodology to give an indication on compliance.
