SBEM Calculations for New Builds
SBEM calculations are required for new build commercial properties and new build projects, in order to demonstrate compliance with Part L2A and L2B (and regional equivalents) of the UK Building Regulations/ Standards.

What are SBEM Calculations for new builds?
It is compulsory for your Building Control Officer to receive a Simplified Building Energy Model (SBEM Calculation) prior to the commencement of any new build construction project, in accordance with Approved Document L2A.
This process is an essential part of the Government’s initiative to reduce carbon emissions, increase energy efficiency and combat fuel poverty. The pre-construction SBEM assessment in the building process verifies that the proposed building design satisfies all requirements as outlined in Approved Document L2A, before works continue onsite and any potential changes become impractical.
Your Building Control Officer must be presented with an updated version of the SBEM Calculation once construction is finalised, including all relevant data from the as-constructed stage of the building plans.
Our team of experts are here to provide you with comprehensive support and detailed analysis throughout this process and ensure you have everything necessary for successful sign-off by Building Control.
Why you need a New Build SBEM Calculation
Simplified Building Energy Modelling (SBEM) is a government-approved methodology and the preferred building energy modelling method for assessing energy in new non-residential and non-domestic buildings and new build commercial properties. These commercial SBEM calculations are vital as they demonstrate compliance with the Building Regulation UK Approved Document L2A.
To make this evaluation, by using building energy modelling software, we compare your building’s calculated Building Emissions Rate against the Target Emissions Rate.
Understanding precisely how much energy is utilised for a building’s heating, air conditioning, and lighting is essential when rating its energy consumption and energy efficiency. It’s the amount of carbon dioxide emitted from the structure that determines where it falls on our concise 1-100 scale. The closer to 100, the less carbon emissions and the greener and more energy efficient the building will be!
When are SBEM Calculations required?
At the start and end of a development venture, you’ll need an SBEM assessment. Focus 360 Energy is highly qualified to evaluate your plans and construction details, and complete both Design and As-Built Stage calculations.
Design Stage SBEM Calculations should be submitted before the commencement of any building work. This report needs to be sent off to Building Control / Warrant Application – either a Building Control Body or Verifier in Scotland – so they can give approval, which is why it’s best to get this done as soon as possible.
And when your construction project is finished, an As-Built SBEM Calculation is necessary for compliance verification. Our team provides reliable expertise during every stage of the process to ensure compliance!
How is a New Build SBEM Calculation worked out?
To ensure every building meets the benchmark of regulation, we set a target emission rate (TER). This is an important measure to pass regulations laid down in Building Regulations Part L. To reach this goal, we calculate and compare the actual building emission rate (BER) with the TER – if it is equal to or lower than the TER, then emissions are in line with regulations. To arrive at these rates, notional values from building regs help establish a baseline for compliance and actual values provide further insight into meeting those requirements.
What steps should be taken to ensure an SBEM Calculations pass?
It’s important to take the right steps during the design phase of the building process of new-build commercial properties to get the best outcome from your SBEM calculations. We can help by advising on energy-efficient lighting, the building fabric of the new-build, proper insulation to reduce heat loss, air conditioning suited to the size of your space, an effective heating system and the incorporation of renewable resources such as solar gains, solar PV or wind turbines for example. Plus, there are other factors that should be taken into account. Get in touch with us now for more information – we’d love to hear from you!
What happens if the new building doesn’t pass?
We understand that completing an SBEM assessment can at times be a bit daunting, especially if the results come back saying the building does not meet Building Regs requirements.
At Focus 360 Energy we are here to help put your mind at ease. Our expert team of consultants will provide you with an informed understanding as to why the building has failed an SBEM Calculation to meet Part L2A of the Building Regs and advise on how any issues could be resolved.
We won’t leave you stranded either; once you have implemented our advice, we can complete another SBEM assessment for you and make sure you are up to date with your Energy Performance Certificate (EPC) and SAP Calculations too.
If your building includes atria, SBEM Assessments are not appropriate for calculating energy performance. In this case, Dynamic Simulation Modelling should be used to generate the Building Regulations Energy Calculations (BRUKL) report.
This type of dynamic simulation modelling requires more detailed analysis and data input than an SBEM Calculation but gives you a greater degree of accuracy and certainty when it comes to meeting building regs standards.
Let our experts guide you through – we’ll make sure you get exactly the info you need from your BRUKL or SBEM report!

With our expertise in this field, we can provide you with peace of mind that these elements meet regulations – allowing you to rest assured that your project is compliant.
What happens if my SBEM Calculations don’t meet the required Standards?
Your commercial energy assessor can help you navigate the complexities of compliance. We’ll review your project design and provide tailored advice on how to achieve maximum efficiency with minimal costs. If you are aiming for higher specs or installing renewable technologies, just let us know—we will incorporate it into our calculations.
Having a commercial energy assessor review your design plans allows them to provide advice on how best to achieve conformity while also taking into consideration any upgrades or renewable technologies you may be implementing. Alternatively, if the project is already built there are still measures that can be implemented such as testing air permeability, installing efficient lighting and adding renewable sources of energy. Your assessor will help you explore all options available ensuring compliance without compromising on cost or complexity.
What are Building Regulations UK Part L2 (BRUKL)
A BRUKL report, which stands for ‘Building Regulations UK Limited’, is an energy assessment used to demonstrate that a building is compliant with Part L2 of the UK Building Regs. This type of assessment, also known as F10 Form or Energy Performance Certificate (EPC), is required by law whenever a property changes hands and/or undergoes significant works such as refurbishment or extension.
Focus 360 Energy offer comprehensive BRUKL reports that are available via their online quote system. Their services include Residential Property Assessments, Commercial Premises, Retail Units and Commercial Property Assessments, and New Build Services such as SAP Calculations, SBEM Calculations and U-Value Calculations to name just a few.
Are SBEM Calculations the Commercial version of SAP Calculation?
How do SBEM calculations make my building more energy efficient?
In addition to providing this information, an SBEM assessment also includes suggestions for cost effective measures which could be implemented in order to improve the energy efficiency of the building. These may include increasing insulation levels, installing more efficient lighting systems or replacing old inefficient appliances with newer models. By making these improvements, you can reduce your overall running costs and save money
