Energy Management & Building Compliance Assessments >>
The Standard Assessment Procedure (SAP) is the Government’s recommended method system for measuring the energy rating of residential buildings. It calculates a dwelling’s CO2 emissions, as well as its typical annual energy costs for space, water heating and lighting.
Having carried out thousands of SAP calculations, our team of accredited SAP Assessors (On Construction Energy Assessors) is well equipped to deliver this service.
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.
New residential buildings must comply with Part L1A of Building Regulations, which stipulates that SAP 2009 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.
Our nationwide team of Energy Assessors can also carry out the required energy calculations to demonstrate compliance with Part L1B, which applies to existing residential buildings. We provide SAP Calculation 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.
We carry out SAP calculations using FSAP 2012, Stroma Tech’s DCLG-approved software package, developed in-house and widely used across the industry. FSAP 2012’s adjustable calculation tools enable us to work to both the SAP 2009 and SAP 2012 standards.
We provide a truly integrated assessment service to assist any type of project.
