SBEM Calculations for Conversions
We specialise in providing SBEM calculations to confirm that any changes to a non-domestic building have been made in accordance with Approved Document L2B. We understand the importance of staying compliant and are here to help you navigate your project.
What are SBEM calculations for conversions?
At Focus 360 Energy, we understand how important it is to stay in compliance with current Building Regulations and Standards. That’s why we offer comprehensive SBEM Calculations specifically designed for Conversions, so you can be sure that your property is always up-to-date. If you have changed the use of a building from its original purpose, an SBEM Calculation for Conversion may be necessary. This could involve transforming the structure into something like a hotel, boarding house, institution or public space – something it didn’t previously serve as.
Additionally, if there is now an area designated for residential purposes in the building or shop where one didn’t exist before; or if the building no longer falls under Building Regulations exemption even though it used to –then this would also classify as a material change in use. Our experts are here to provide helpful advice and support along the way, giving you all the guidance needed to ensure a successful outcome.
How we help
In order to ensure compliance with approved building standards, the calculated CO2 emission rate for your proposed construction must be lower than if it were built to the minimum requirements of Approved Document L2B. The Government’s certified SBEM methodology will help you calculate energy performance accurately and efficiently. Our team is here to provide you with educated advice and guidance throughout this process so that your building meets the necessary standards.
Let us help make your conversion process smooth and stress-free!
When you will need a SBEM Calculation for a Conversion
Material Change of use
Talking about commercial building conversions, it’s important to note that they need an SBEM Calculation in order to follow Part L2B of the Building Regulations (or a regional variation). A conversion typically takes place if there is a ‘Material Change of Use‘, which is when the purpose or use of the building alters. For your reference, here are some examples of what counts as a ‘Material Change of Use’, according to Building Regulations/Standards:
- The building is used as a hotel or boarding houses where it was previously not
- The building is used as an institution or school where previously it was not
- The building is used as a public building where previously it was not
- The building is used as a dwelling where previously it was not
Change of Energy Status
Introducing heating and cooling to a building that has yet to experience it can certainly be a daunting task. However, by taking the extra steps of obtaining an SBEM Calculation, you’ll ensure that your building is compliant with all energy efficiency standards set out in Building Regulations. This will also allow for greater design flexibility, guaranteeing that the CO2 emissions produced are no worse than if the building had been previously improved.

Frequently Asked Questions
SBEM stands for Simplified Building Energy Model. It’s the UK government’s approved method for assessing the energy performance of non-domestic buildings, like offices, shops, and factories. It predicts energy consumption and carbon emissions, which are then used to generate an Energy Performance Certificate (EPC).
SBEM calculations are mandatory for most new non-domestic buildings and significant extensions or renovations. They’re essential for demonstrating compliance with Part L2A of the Building Regulations, which sets energy efficiency standards.
Ideally, you should get an SBEM assessment done at the design stage of your project. This allows you to identify and address any potential energy efficiency issues early on, saving you time and money in the long run. However, a final SBEM assessment is also required upon completion to obtain your EPC.
The SBEM rating is influenced by various factors, including the building’s fabric (walls, roof, floors, windows, doors), heating, cooling, and ventilation systems, lighting, renewable energy installations, occupancy patterns, and climate data.
While it’s best to optimise energy efficiency during the design phase, some improvements can be made after construction. However, these can be more costly and disruptive. A professional SBEM assessor can advise on potential retrofitting options.
The cost varies depending on the complexity and size of your project. Focus360 Energy offers competitive pricing and can provide you with a free, no-obligation quote.
An EPC (Energy Performance Certificate) is a legal requirement for most commercial buildings when they are built, sold, or rented out. It provides a rating from A (most efficient) to G (least efficient), indicating the building’s energy performance. A good EPC rating can attract tenants and potentially increase the property’s value.
We offer a range of services to support your building’s overall performance, including TM52 overheating assessments, air tightness testing, ventilation assessments, and energy audits.
Design Stage SBEM Calculations are imperative to complying with Building Regulations/Standards before construction or development projects can begin. The Target Emission Rate (TER) is set at the design stage to ensure that the CO2 emission rate of the building meets the minimum standards for energy performance – based on a notional building which shares similar shape and orientation as your own. We also establish a Building Emission Rate (BER) based on your building plans, which should not exceed the TER; if it does, we are here to help you adjust the designs in order to be compliant.
Once the construction of your commercial building is complete, submitting an As-Built SBEM Calculation to a Building Control body is essential for building sign off. An EPC can then be generated for sale of leasing requirements. With buildings boasting less than 500m2 in useful floor area, air pressure testing isn’t necessary; due to the 15m3/(h.m2) at 50 Pa as part of the Building Emission Rate (BER) calculation. Comparing the Design Stage TER with the BER reveals if any further action needs to be taken – and that’s where Focus 360 Energy Ltd come in! Our expertise and consultancy experience guarantee your building will comply with all regulations.
