SBEM calculations

What are SBEM calculations?

A SBEM Calculation is used to calculate the compliance of your new build commercial property with Part L Building Regulations.

SBEM is the Simplified Building Energy Model. This is a government approved methodology which is used to calculate the energy required to heat, cool, ventilate and light a non-residential building over a 12-month period when used under ‘normal” circumstances.

The amount of carbon dioxide the building emits is also calculated, before then assigning the building a numerical rating. The lower the rating, the more energy efficient the building is deemed to be.

Our energy assessors are highly skilled and knowledgeable. All of our assessments are carried out using the SBEM Online software.

SBEM Calculations from Eecobuild

An SBEM calculation is a model that provides a clear picture of the energy performance and carbon emissions of your proposed building. It is a SAP calculation for a non-residential property.

SBEM uses the National Calculation Method (NCM) to calculate the proposed buildings annual energy use and can also identify ways to save money.

It also takes into account the U-Values of the building fabric/thermal elements (roofs, walls, windows), and once constructed, the air tightness of the building.

Finally, it’s an important tool in helping the Government drive down carbon dioxide emissions and achieve its specified annual carbon targets, to ensure we are making positive steps to a greener future.

Just like with a SAP calculation, an Energy Performance Certificate (EPC) is produced

When are SBEM calculations needed?

>There are a number of different types of commercial buildings that do need an SBEM calculation, from new builds over 50 metres squared to extensions and refurbishments too, including:

Offices
Warehouses
Retail units
Restaurants
Leisure centres
Retirement homes

However, there are some exceptions where SBEMs may be not be required, such as places of worship and unheated buildings. If you are unsure as to whether your new development will need to undertake this assessment, contact us at Eecobuild.

What information would I need to provide?

The following information is required to provide a full calculation:

The building construction plans
The types of heating to be used
The types of lighting to be used
The ventilation and air conditioning that will be used
The use of any renewable energy sources (solar PV, wind turbines and ground/air-source heating etc).
