SBEM, the Simplified Building Energy Model, is the official
UK tool for calculating the predicted carbon dioxide
emissions due to heating, cooling, lighting, ventilating
and providing hot water to new non-domestic buildings.
Building Regulations Approved Document Part L2A
requires SBEM calculations to be performed on new
non-domestic buildings to demonstrate that the
building carbon dioxide emission rate (BER) is less than
the target emission rate (TER), which is based on the
proposed building with a notional specification.
SBEM can also be used to demonstrate compliance with
Building Regulations Approved Document Part L2B for
extensions and refurbishments to existing non-domestic
Following the 2013 uplift in Part L Building Regulations it is even more important to use an experienced SBEM assessors to ensure that the proposed building fabric and building services specification are the most efficient solutions to demonstrate compliance against Building Regulations.
Building Control require a submission of SBEM calculations at both the design stage and on completion in order for the building to be signed off by the Building Control Officer.
CHB Sustainability have experienced and accredited SBEM assessors knowledgable in low energy construction and able to provide detailed advice on: Orientation and Layout; U-Values; Construction Details; Fabric Air Permeability; Building Services; and Renewable Energy.
Our experience of BREEAM and low carbon design means that we are well placed to provide detailed guidance to minimise carbon dioxide emissions far beyond the minimum Part L requirements in order to achieve BREEAM ratings of Excellent or Outstanding.
