Simplified Building Energy Model (SBEM)
SBEM stands for Simplified Building Energy Model, and it is the preferred method of the government to assess energy in non-residential buildings.
We can help you increase the performance of your building or estate – from the energy strategy and early design stages to digital modelling, design and compliance.
These calculations are incredibly important as they are used to prove that the building conforms to the regulations laid down in Building Regulations Approved Document L2A. It does this by comparing the designed Building Emission Rate (BER), with the Target Emission Rate (TER).
Essentially, SBEM calculations are like SAP calculations, but for non-residential premises. They calculate the amount of energy used by a building, through such things as heating, air conditioning and lighting, as well as the amount of carbon dioxide the building emits, before then assigning the building a rating between 1 and 100.
The closer to 100 the rating is, the more energy efficient the building is deemed to be. A BRUKL certificate is then issued, and if the project meets the requirements it will have passed Building Regulations Part L.

There are a number of different types of buildings that will need an SBEM or digital building model.
These include, but are not limited to:
• Shopping Centre’s
• Offices
• Restaurants
• Retail units
• Leisure Centre’s
• Retirement homes
• Warehouses
In addition to the above, it is important to remember that an SBEM assessment can be needed not only for new builds, but also for extensions and refurbishments too.
There are some exceptions as well, such as places of worship and unheated buildings. Please feel free to contact us today for more information on this.
We know that, to the uninitiated, SBEM calculations might seem a complete mystery – something that they feel they will never understand. We want you to know exactly what an SBEM assessment entails though, so we have answered some of the most common questions about the process below.
For more detailed answers – or for answers to any other questions you might have – please contact us today for a no obligation discussion about your requirements.
If you don’t have an up to date asset register or any other information don’t worry.
As part of our service we can arrange to conduct a pre-survey site and systems check.
Who Needs an SBEM Assessment?
An SBEM assessment is now a mandatory requirement for all new commercial premises with a size of over 50m2. It can also sometimes be the case that an extension or a renovation needs an SBEM assessment as well, although this varies from situation to situation – if you are having either of these, we advise you to call us as soon as possible so we can advise you on your specific case.
When Should an SBEM Assessment be Carried Out?
An SBEM assessment comes in two parts. The first part is the design stage SBEM assessment, which needs to be completed before the construction starts. It is important to start the process well in advance, so that there is time to resolve any problems before the building process begins. When this process has been carried out and the building passes the regulations laid down in Part L, the construction can begin (providing the local authority doesn’t need any other assessments carried out, such as BREEAM).
When the building is completed, the second stage of the SBEM assessment is carried out. This is called an as-built SBEM and will also include the results of an air permeability test (If completed). An Energy Performance Certificate is then issued.
How is a New Build SBEM Calculation Worked Out?
Every single building will have a target emission rate (TER), based on a number of different factors. This is the benchmark that the building has to comply with – if it doesn’t it will not pass the regulations laid down in Part L.
To ascertain whether the building meets the standard required, we produce a building emission rate (BER). In order to pass, the BER must be of an equal or lower amount to the TER, therefore showing that the emissions are lower than the target. TER is derived from the building model using building regulations notional values, while DER uses actual values and compares the proposed plans against building regulations standards.
What Can Be Done to Ensure a Pass?
There are a number of things that should be thought about at design stage, prior to the SBEM assessment beginning, in order to give the best chance of getting a good result.
These include:
• Ensuring that the lighting is as energy efficient as possible.
• Making sure that the house is insulated well and that no heat is escaping through walls or the ceiling.
• Ensuring that the air conditioning is appropriate for the size of the dwelling.
• Making sure the heating is also suitable for the size of building it will be heating.
• Installing ventilation that is effective.
There are, of course, many other factors to consider as well. For a comprehensive discussion on this, call us today.
What Happens if the Building Doesn’t Pass?
When we complete an SBEM assessment, we are obligated to provide a fair and accurate representation, therefore it is sometimes the case that we have to say a building does not meet the requirements laid down in Part L of Building Regulations. If this does happen, there is no need to panic though, as we will help to advice on any problems and get your project back on track.
When some companies complete an SBEM assessment, they only provide the results and fail to tell the client the exact reasons why the building has not met the requirements. At Future Energy Performance though, we will provide you with the reasons and also supply you with a number of different ways in which you can adjust the plans to get the SBEM calculations to produce the right result. We will then complete another SBEM assessment for you.

Thanks for the quick quote information!
Need some help? No problem.
If you don’t have an up to date asset register or any other information don’t worry. As part of our service we can arrange to conduct a pre survey site and systems check.
The cost varies depending on the length of time it will take to complete the survey and report. This is dependent upon the size and complexity of the A/C systems installed and the premises. The more information you can supply at this stage the better. Please email us with your contact details and we should be able to give you a quotation after our first discussion.
Once the site survey is completed, we aim to provide you with draft reports and certificates for checking within 3 days for small to medium sites and 10 days for the much larger projects. We will always keep you advised of progress.
We can arrange a pre survey site visit to obtain the information we require in order to quote you accurately for your requirements. The cost of this would be absorbed within and not in addition to our TM44 charges.
In addition to possibly missing out on zero cost implementation -energy saving recommendations, you could be fined by Trading Standards per premises or per zone on a one off or roll over basis until you complete. In addition to this, you may not be able to gain accreditation or renew accreditation to bodies like the ISO without full EPBD compliance.
No – Whilst it is a mandatory requirement to have a valid TM44 issued, implementation of the energy savings recommendations suggested is not monitored.
We have our own team of highly experienced licensed engineer assessors throughout England, Wales, Scotland.
