SBEM Calculations

SBEM  known as  simplified building energy model, provides an analysis of the energy consumption of a building. The SBEM calculates the monthly carbon dioxide emitted and energy used by a building given its construction, geometry, use, lighting equipment and HVAC. SBEM ratings are scored from a scale of 1 to 100, with 1 being the worst and 100 being a zero usage of energy.

In order to comply with Building Regulations Part L1B it is necessary to have SBEM calculations carried out on non-domestic construction projects. The SBEM calculations produce an SBEM report certificate which shows the SBEM rating for the building in question. If the SBEM report certificate shows a pass then the project passes Building Regulations Part L1B. SBEM calculations and the requirements of the SBEM report vary depending on whether it is a new build, extension or a refurbishment.

New build SBEM calculations work out the target emission rating (TER) followed by the building emission rating (BER). The BER must be equal to or less than the TER in order for the SBEM rating to show a pass on the SBEM report certificate.

When non-domestic buildings are extended the above SBEM calculation rules apply but only to the new build portion of the building. The SBEM requirements do not apply to the existing section of the building.

SBEM calculations for conversion projects are different however. The SBEM report needs to show that the thermal elements such as walls, floors and glazing have been updated to minimum standards.

For any further information on SBEM calculations feel free to call and speak to one of our experienced assessors.

SAP Calculations/ SAP Calcs/ SAP Assessments/ Predicted Energy Assessement

SAP is the Government's Standard Assessment Procedure for Energy Rating of Dwellings. SAP 2005 is adopted by government as part of the UK national methodology for calculation of the energy performance of buildings. It is used to demonstrate compliance with building regulations for dwellings - Part L (England and Wales), Section 6 (Scotland) and Part F (Northern Ireland) - and to provide energy ratings for dwellings.

SAP Reports use the Standard Assessment Procedure to provide the compliance material to building regulations Part L. The Standard Assessment Procedure is the Government’s method system for measuring the energy efficiency and carbon emission rates of residential dwellings.

We provide SAP calculations and adjustments and consultancy. The SAP calculations are necessary for Building regulations Part L compliance for all new build projects, conversions and extensions where the glazed area is over 25% of the floor area.In domestic and commercial properties the SAP calculations are undertaken at the beginning of the design process, during and at completion. This enables you to keep abreast of any changes during the build that may affect the energy rating of the project.

Your architect, builder or developer or if you are a homeowner and are building an extension you will require SAP Cals.. It is the owners responsibility to provide an EPC when the home is constructed, or has been converted; any material change of use made to the heating, hot water provision or air conditioning/ventilation services.

If you are selling a home before it has been built you will be required to provide information about the energy efficiency in a Predicted Energy Assessment (PEA). This is a predicted SAP and Environmental Impact rating from the SAP Calcs and is carried out in the design state to ensure that the building will meet the required energy saving targets.

For  any  help for your SAP calculations, please contact Energy Assessors London Ltd, where our  team of experienced assessors will be happy to assist you.

Our service includes advising our clients on how best you can comply with the regulations. We try to advise on cost and energy saving options that are available. Alterations are free of charge and our SAP assessors will also liaise with Building Control Officers.

At Energy Assessors London we also provide SBEM calculations, Air Testing and Sound Testing.

We aim to maintain a high standard whilst keeping our prices competitive.
