Building Regulations
EPC/SBEM for existing commercial buildings are governed by Part L2B regulations which are much less stringent than Part L2A regulations used for New Builds.
There are minimum standards laid out in the Part L2B for building fabric, building services, windows, doors, and rooflights when carrying out works on existing buildings. However, if certain standards can not be met, compliance can still be achieved by compensating in a different area to offset the carbon emissions.
These calculations are used to produce an EPC for the building, which is a requirement when it is being rented, sold, or modified (in case of existing buildings). EPC’s are valid for 10 years and in case your building does not have one, you will be required to produce an EPC before it can be sold or rented.
How we help
We advise clients to involve us early at the design stage to maximise all opportunities to reduce energy consumption and provide cost-effective solutions. We will help your building achieve compliance with Part L regulations by assisting in developing a design for your extension that produces no additional CO2 emissions.
An assessment will be carried out at the design stage to produce an estimated EPC and showcase how energy efficient the building will be.
We identify areas of improvement in both the new and existing elements of the building and come up with a plan of action laying out how these can be incorporated into the design.
Once the building reaches completion, a final ‘as-built’ EPC will be produced using the installed buildings services, and fabric specifications used for the works.
