Extensions where the new glazing exceeds 25% of the total floor area of the extension. Building Control will require a SAP Calculation to demonstrate compliance
Residential Conversion, Barn Conversion ,Change of Use
A SAP Calculation will be required to demonstrate compliance for a barn conversion, or a change of use from a commercial property to a residential dwelling, or from a single dwelling into flats.
Design & As Built
The Standard Assessment Procedure (SAP) is the methodology used by the government to assess and compare the energy and environmental performance of dwellings which will ensure compliance with Part L
Design & As Built
SBEM calculates the emissions of a building based on its size, orientation, geometry, construction and HVAC to demonstrate compliance with Part L
U Value Calculations
A U-Value calculation is a computer-based assessment that measures the total thermal resistance of a structure. The unit of measurement for U-Values is given as W/m2K (Watts per square metre degree Kelvin);
Energy Performance Certificate's (EPC) are required if you rent out or sell premises. A building under construction is finished or if there are changes to the number of parts used for separate occupation
Psi-Value Calculations Thermal Bridging modeling
From the 15th June 2022 ,Building Regulations Part L 2021 and SAP 10 come into effect and one of the changes will be removal of the option to use Accredited Construction Details for the thermal bridging in a building Thermal bridging is the movement of heat across an object that is more conductive than the materials around it. Thermal bridging can be a major source of energy loss
Coming Soon Overheating Assessments Building Regulation Part O
From 15th June 2022 all new dwellings in England will require an overheating assessment .Building Regulation Part O is a legal requirement for developers to provide Building Control Bodies with evidence to show they have reduced the risk of overheating
