SAP Calculations determine the CO2 emission levels and typical annual energy costs (including space, water heating and lighting) for domestic dwellings. Stroma Built Environment delivers compliant and highly competitive SAP Calculations for new and existing residential properties to ensure your building stock is compliant with the Government’s Standard Assessment Procedure (SAP).
Stroma Built Environment employs a skilled and fully certified team of SAP Assessors (On Construction Energy Assessors) to support your project. We are experienced in measuring the energy rating of residential buildings and have conducted thousands of SAP Calculations on a range of domestic property types.
Our services span both new and existing residential houses:
We have assisted in formulating the compliance strategy for challenging developments such as high-rise buildings and high sustainability projects. Also, if your specification is not on target to meet the required limits, our experienced assessors can provide advice on how to resolve this, ensuring a smooth submission to Building Control.
Stroma Built Environment offers SAP Calculation services covering both Part L1A (New Residential Houses) and Part L1B (Existing Residential Houses):
New residential buildings must comply with Part L1A of Building Regulations, which stipulates that SAP assessments must be undertaken, and submitted to Building Control prior to the start of any works on site. All SAP assessments must be undertaken by accredited Energy Assessors. Upon completion of the build, the SAP assessment is upgraded to an As Built SAP calculation incorporating any changes from the initial design.
SAP Calculations are required for converted dwellings, extensions and conservatories.
SAP Calculations for converted dwellings: The conversion SAP calculation assesses the thermal efficiency of the proposed building fabric, together with the energy requirements of the heating, lighting and hot water systems. However, compliance with any prescribed limits on carbon dioxide emissions is not currently required.
SAP Calculations for extensions and conservatories: For extensions, two alternate extension SAP calculations are produced: a notional SAP calculation based on the existing property with a conventional extension to the dimensions as proposed. Also, a second extension SAP based on the proposed extension.
All our SAP calculations are carried out using FSAP Software – developed by our sister company Stroma Software. This DCLG-approved software package is widely used throughout the construction industry and allows our SAP assessors to work in compliance with the Government’s SAP methodology. FSAP provides all indicators of energy performance including the FEE rating, SAP rating and Environmental Impact rating.
Thank you for completing the Daylight Assessments, Energy Reports and SAPs for our 5 sites…Throughout the process of providing us with a report for our planning application, I have found working with yourself and Stroma to be an extremely professional and pleasant experience.
