Building Regulation Part L2

The European Directive on the Energy Performance of Buildings came into effect in January 2006. It is being implemented in the UK through changes introduced in Part L of the 2010 Building Regulations as amended in 2013 and 2016.

Compliance with part L2A for new buildings must be assessed by a competent person using the Simplified Building Energy Model (SBEM) or one of the approved tools developed by software vendors.

Our Low Carbon Consultants have been assessed as competent to use DesignBuilder SBEM and DesignBuilder DSM software tools. The DSM software allows more features of the building as designed to be accurately modelled. It is particularly beneficial to use the DSM software for cooling dominated buildings when there is significant self-shading or shading from surrounding buildings.

We have many years’ experience of working with design teams to optimise the building’s energy performance within the constraints of the site and within budget.

Improvements to existing buildings must comply with Part L2B of the Building regulations. The regulations apply to controlled fittings and controlled services using an elemental approach. Improvement measures to comply with MEES will need to comply with Part L2B.

We draw on our experience of ESOS audits to assess all possible improvement measures and rank them according to energy savings and payback or other financial criteria.
