Energy Assessment

At BM3 we will carry out Standard Assessment Procedure (SAP) the methodology used to assess and compare the energy and environmental performance of dwellings. Its purpose is to provide accurate and reliable assessments of dwelling energy performances that will produce EPC Certificates. SAP quantifies a dwelling’s performance in terms of energy use per unit floor area, a fuel-cost-based energy efficiency rating (the SAP Rating) and emissions of CO2 (the Environmental Impact Rating). This can be used on new dwellings and existing using Design SAP 20212 software.

We have extensive experience within this important area and have worked with many clients and developers achieving high standards of Sap and Building Compliance.

The Government has set a target for the UK to reach net zero in carbon emissions by 2050 and has already identified that improvements to existing homes are required in order to achieve this. It is anticipated that PAS 2035 will need to be adopted for all retrofit improvement programmes in the future. We can guide you through how the process works and the quality standards that should be met when carrying out these works.

Services that are provided by BM3:

  • Sap Calculations to produce As Builts Saps with Building Compliance and EPC Certificates.
  • Future Homes Standards and proposal changes to Part L and Sap.
  • Energy Statements showing improved energy performance will be achieved showing consideration of fabric performance and renewable technologies.
  • Low carbon design with advise on windows/Glazing and selection of materials with use of heating/renewable technologies.
  • Advise on specifications, Producing specifications to pass Saps and Future Homes Standards.
  • U Values – working out heat transfer through floors, walls, roofs and openings.
  • Daylight calculations carried out to determine the capability of natural light that is predicted to enter a room.
  • Water calculations providing calculator to comply with Building Regulations.
  • Condensation Risk Analysis will model movement of water vapour across the walls, roof and floor construction
  • For retrofit works, we can produce an RdSAP Energy Report, a detailed floor plan, a condition report and an occupancy assessment
  • DEA qualified producing Energy Report and EPC Certificate on existing buildings.

Kings Hill, Kempsey

The Kings Hill development in Worcestershire proposed 38 residential dwellings comprising a range of bungalows, flats, detached and semi- detached housing for affordable rent and open market sale. BM3 produced design and as built Saps with PEA/EPC Certificates for the 38 plots to achieve 10% reduction in C0² using renewable energy PV Panels.

During the consultation with the client we have discussed many options, including solar thermal, and even a fabric first approach. We have decided the best way to achieve the 10% energy reduction, is by the use of photovoltaic panels.

Goscote, Walsall

The £56 million development forms the third and final phase of the ambitious Goscote Lane Corridor regeneration programme, the largest building scheme of its kind in the borough. Once completed, the scheme will have delivered more than 800 new, energy-efficient homes to North Walsall. The third phase will see a mix of 2, 3 and 4 bedroom homes built by Keepmoat Homes; 281 for private sale and 126 for social and affordable rent.

BM3 produced design stage Saps/ PEA Certificates and As Built Saps/EPC Certificates for all plots in the third phase. During the consultation with the developer, it was decided to provide fabric first approach with A rated boilers. We are delighted that it was also held up as a best example in the National Housing Federation’s (NHF’s) Great Places Commission report.
