SRE undertakes Building Regulation Part L Compliance checks (SAP and SBEM).  These checks are required to meet building regulations and are used, with dynamic modelling, to inform Energy Statements and Energy Strategies.

SAP/SBEM energy ratings provide a means of assessing and comparing different buildings with respect to their thermal performance, fuel supply and system specification.  Energy Performance Certificates (EPCs) are generated from the SAP/SBEM calculations and are mandatory for all new buildings.

SRE provides detailed modelling and technical advice to enable residential and commercial buildings achieve the increasingly complex Part L requirements in the most economical and practicable ways.
