SAP Calculations For New Builds
Why Your New Build Needs SAP Calculations
L1A SAP calculations for new builds are required to make sure your building complies with Part L Building Regulations in England and Wales, or Section 6 in Scotland or Part F1 in Northern Ireland.
These calculations are concerned with energy efficiency. Most importantly, they are necessary to produce an Energy Performance Certificate (EPC). This is part of the government’s plan to reduce carbon emissions and tackle fuel poverty. It is important to note that it is against the law to rent or sell a dwelling without an EPC.
Calculations With UKBC
We recommend you commission your SAP calculations for new builds at design stage. Therefore, should your building be failing to meet requirements, our team can advise you on how to improve. This is far easier and cheaper at design stage, when the scope of possible changes is more flexible.
UKBC L1A SAP calculations come in two stages: a ‘design stage’ SAP report and an ‘as built’ SAP report. These calculations will measure a number of aspects of the building’s energy performance. However, the primary purpose of these calculations is to produce the EPC. This process includes:
- Assessing the area of the external building fabric and openings.
- Analysing the building's construction materials.
- Understanding the energy consumption of the heating systems, lighting, ventilation systems and renewable technologies.
- Inputting this data into SAP calculations software in order to produce Target Emissions Rates (TER) measurements, Target Fabric Energy Efficiency measurements (TFEE) and to demonstrate that the building is Dwelling Emission Rate (DER) and Dwelling Fabric Energy Efficiency (DFEE) compliant.
