SBEM Calculations
Simplified Building Energy Model (SBEM) calculations are a key requirement for demonstrating compliance with Part L of the Building Regulations for non-domestic properties. Whether you’re working on a new build or a conversion, our SBEM assessments will help ensure your project meets the necessary energy efficiency standards.
Commercial assessments are categorised into three different levels. For anything requiring a BRUKL, a minimum level of 4 is required. The higher the level, the more detail we must consider.
Our assessors are licensed by DesignBuilder Software, enabling us to assess up to Level 5 Dynamic Simulation Models (DSM) with intricate detail. This also allows us to run simulations throughout the process, helping you comply with other building regulations, such as Part O.
At JosTec, we provide comprehensive Delivery Noise Management Plans (DNMP) designed to minimise the noise impacts of deliveries and vehicle use on-site, ensuring compliance with noise regulations while protecting nearby residential properties.
What type of SBEM assessment do you need?
SBEM calculations fall into three levels, depending on the complexity and size of the building.
Level 3 – Applies to small and simple buildings such as small offices, retail units, and industrial warehouses. These buildings have straightforward heating, cooling, and ventilation systems.
Level 4 – Covers more complex buildings with advanced HVAC (heating, ventilation, and air conditioning) systems. This includes larger office buildings, multi-storey retail units, and mixed-use developments.
Level 5 – Required for highly complex structures with advanced energy systems, such as large commercial spaces with atriums, shopping centres, and specialist buildings with unusual features.
Why are SBEM calculations important for new builds and conversions?
Newly constructed or converted commercial properties must meet strict energy efficiency requirements. Our expert team ensures your SBEM calculations are completed accurately, helping you achieve compliance quickly and avoid costly delays.
