One of our experienced SBEM assessors will be able to guide you through the process to ensure you achieve the results  and SBEM certificate you require, allowing you to pass building regulations on time.

SBEM Calculations for
Commercial New Builds

An SBEM Calculation is a calculation used to predict the energy efficiency of a new build commercial building. The SBEM certificate issued once the calculation has passed compliance is used as part of L2A building regulations. Without this certificate you cannot legally sell or rent your property. 

SBEM calculations in England and Wales calculate how much CO2 emissions are being emitted from a commercial building. In order to pass your SBEM calculations you must reach a certain score, which is dependant on the building specifications. Once this score has been achieved you will receive an SBEM certificate which is part of your EPC (Energy performance certificate).
SBEM calculations are completed in two stages:​ Design Stage & As-Built Stage.

Design Stage

SBEM calculations are completed by our trained SBEM assessors.
All we need from you are elevations and design plans and we can complete your audit and provide you with an EPC. Plans and designs can be changed during the design stage by your architect to improve the energy efficiency of your building to pass compliance. This can be done by changing the building specifications.
​If your SBEM calculation does not pass first time, cost effective solutions can be discussed by our trained SBEM assessors to get you back on track with passing your calculations. A more air tight building may be a solution to this problem. 

​When a finalised specification has been agreed, we can produce a design stage SBEM calculation that can be issued to building control.


Our SBEM software will take into account the building specifications and the air tightness test results. If any editing is needed to reach compliance, one of our trained SBEM assessors will do so accordingly. If this cannot be done, our assessors will provide you with more remedial advice. 

Our SBEM assessor will finalise the SBEM calculations and create the Energy Performance Certificate (EPC) along with the As-Built SBEM, which must be issued to building control for their final sign off procedure.

What we need from you?

For our assessors to prepare and complete your buildings SAP calculations we will need the following drawings and specifications from you;

Elevation drawings
Floor plans
Section drawings

Site plans
Door specifications
Heating specifications

Ventilation specifications
Glazing specifications
Lighting specifications
