Syntegra Consulting have been appointed as energy consultants to ‘Sandilands, 5 Gorse Hill Lane, Surrey’ to assess the compliance with Building Regulation Part L1B.
Standard Assessment Procedure (SAP) calculations was undertaken. A notional calculation using SAP Appendix R was undertaken on the extension of the dwelling followed by the actual data to demonstrate improvement in the CO2 emissions.

Part L of the Building Regulations focuses on the conservation of fuel and power in buildings. For extensions and improvements, it mandates specific energy performance standards to ensure new work and affected existing elements meet minimum efficiency requirements. This aims to reduce carbon emissions and improve the overall energy efficiency of the building.
Syntegra Group offers a range of services relevant to Part L compliance, including Energy Strategy Reports, Sustainability Assessments, and SAP & SBEM Part L Calculations. These services help in assessing, planning, and certifying that building extensions and improvements meet the necessary energy efficiency standards required by the regulations.
Key considerations for energy efficiency in extensions and improvements typically include enhancing insulation for walls, roofs, and floors, specifying high-performance windows and doors, and integrating efficient heating and ventilation systems. Compliance often requires demonstrating that the proposed changes meet specific U-values and do not negatively impact the energy performance of the existing structure.
