Case Studies - SAP Calculations

SAP calculations are an essential part of any domestic project, from single homes to complex developments of several hundred properties. They can also be carried out for domestic extensions. The calculations model the energy efficiency and carbon dioxide emissions of dwellings and demonstrate building regulation compliance. Even if a project is aiming for the Passivhaus standard, or net zero carbon, SAP calculations are still required. The following case studies show the versatility and expertise of the Darren Evans team in providing SAP assessments, often alongside other services, to deliver efficient, value engineered specifications.
