Simplified Building Energy Modelling (SBEM) Calculations

What are SBEM Calculations?

Simplified Building Energy Modelling (SBEM) is the government approved methodology for calculating the energy efficiency of commercial and non-domestic buildings in the UK. Based on a 12 month period of normal use, it provides an accurate overview of the amount of energy consumed by a building and the carbon emissions produced month to month, allowing conclusions to be drawn about the constructionā€™s energy efficiency.

SBEM calculations allow you to do two things:

  • Ā Demonstrate compliance with Part L of Building Regulations
  • Produce an Energy Performance Certificate (EPC).

They can be particularly important at the design stage of a project before the commencement of the build to ensure the projected design will achieve Part L compliance early on, and during the project to verify its progress. By booking an SBEM assessment with our expert team, you can ensure that whatever stage your project is at, you will achieve total compliance, and identify measures to reduce the buildingā€™s carbon footprint. SBEM calculations are also required for extensions or conversions to commercial properties, and we can advise on where these are needed.

To achieve the highest levels of Part L compliance, we recommend taking the following crucial actions:

  • Carry out SBEM at the design stage of a project.
  • Beat the minimum requirements. MinimumĀ U-ValuesĀ set by building regulations are designed to be exceeded, and this is best done using high performing materials.
  • Install an efficient and appropriate heating system, avoiding electric heating panels where possible.
  • Manage your ventilation and solar gain using passive measures like solar shades and coated windows.
  • Choose low energy lighting like LEDs throughout the construction for their efficiency and long life.
  • Build as air tight as possible, andĀ air test your building.Ā 

If youā€™d like to book a SBEM assessment with Cook Brown Energy, donā€™t hesitate to contact our expert team. We provide a fully supportive consultancy service for design stage and as built SBEM calculations. We can also carry out elemental (walls, floors and roofs) U-Value calculations, and provide Landmark Registration and Energy Performance Certificates.
