Standard Assessment Procedures (SAP's) are a fundamental, legal requirement with new build, conversion or extension projects and it's important that all the boxes are ticked in order to move forward with your venture.

At Falcon Energy, we have extensive experience in providing such SAP's, including the all-important SBEM (Simplified Building Energy Model) calculations. If you have a new build project approaching or are looking to convert or extend your commercial property, call us on 01403 253439 to get your essential SAP's sorted.

What is an SBEM calculation and why are they important?

SBEM (Simplified Building Energy Model) Calculations are used to determine how energy efficient a commercial property is in line with government regulations, and are performed by experienced energy assessors at Falcon Energy across the UK.

A government-approved approach, SBEM Calculations quantify how much heat, light and ventilation a commercial or other ‘non-dwelling’ property uses in a 12 month period under normal circumstances. This is used to determine how energy-efficient and environmentally friendly it is overall. They're important, particularly for new buildings and conversions, to ensure the property is not using too much energy and creating excess waste.

Commercial sectors

We can provide SBEMs for a range of commercial properties, including:

  • Offices
  • Warehouses
  • Leisure centres
  • Hotels
  • Hospitals
  • Restaurants
  • Retail shops

At which stage should you request an SBEM calculation?

It’s extremely important that you instruct a qualified energy expert to undertake your SBEM calculations as soon as possible within a project. The earlier that an assessor is instructed, the smoother the process will be.

It can prove to be costly if you instruct someone at the later stages of the build, as changes may need to be made to already built elements of the property, which can put the whole project on hold and cost a lot to rectify. Getting a company on board at the design stage of the project is preferable, so any necessary changes can easily be made to the plans to ensure the property is compliant and efficient.

What documentation do you need to provide?

Once you have a knowledgeable energy company to work on your build, a range of different documentation is required in order to provide an accurate calculation, including:

  • Which types of heating are going to be used on the building
  • The types of lighting to be used
  • Ventilation and air conditioning systems
  • The construction plans of the building
  • Any renewable energy sources that are going to be used, such as solar panels and grand or air source heating
  • The materials used on the building - such as walls, windows and roofs

Once all of this information has been provided, calculations can be completed to work out the overall SBEM calculation, which will then be able to provide a clear idea of the energy performance of the building.

Frequently Asked Questions

What is an SBEM?

An SBEM is used to assess how energy efficient a commercial property is and stands for ‘Simplified Building Energy Model’.

It’s a computer programme that calculates results based on a building’s energy use and carbon dioxide emissions. It is required by law for the construction of and alterations to commercial buildings.

As a result, there are two types of SBEM;

  • SBEM L2A - new commercial buildings prior to construction
  • SBEM L2B - existing commercial buildings undergoing alterations

When do you need an SBEM?

If you’re an owner or developer working on construction for a commercial property then you will need to arrange for the building to undergo an SBEM assessment. This is required by law. This includes all new commercial buildings and extensions such as offices and storage units.

An SBEM should be undertaken before the building work starts to ensure the building will comply with energy efficiency building regulations. A building will likely have multiple SBEM checks throughout its lifetime.

What happens after an SBEM?

It may result in construction plans changing to meet energy efficiency standards, or it will mean the project can go ahead as planned if the calculations are within regulations.

The results of an SBEM will be affected by a building’s heating ventilation, air conditioning systems and lighting equipment. It may find that these systems need to be improved to meet standards and achieve cost savings in the long term.
