What are SBEM Calculations?
As the building industry are constantly looking towards building ‘greener’ and more sustainable developments, standards for energy efficiency are becoming higher. It is vital that any new building is well insulated and has the most efficient heating, cooling, lighting and ventilation systems – and this is where SBEM calculations are important.
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.
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:
