SAP assessments measure the energy efficiency and carbon emissions of residential buildings and are required for all new builds, extensions and conversions.

We provide accurate Part L1A and L1B SAP calculations to help you meet Building Regulations and avoid delays at design and completion stages.

SBEM assessments are essential for demonstrating compliance for new or refurbished non-domestic buildings over 50 sqm.

We deliver compliant SBEM calculations for commercial new builds, large extensions, conversions and shell-and-core fit-outs across England, Wales, Scotland and Northern Ireland.

Part O and TM59 assessments ensure new homes are designed to prevent overheating and maintain safe, comfortable temperatures.

We offer both Simplified Method assessments and Dynamic Simulation Modelling to evaluate glazing, shading and ventilation strategies for full compliance.

TM52 assessments evaluate the overheating risk in non-residential buildings using adaptive comfort modelling.

Through Dynamic Simulation, we analyse your design against CIBSE’s key comfort criteria to identify potential overheating issues and recommend practical design improvements.

Daylight and sunlight assessments help demonstrate that your development receives sufficient natural light and meets planning, HQM and BREEAM requirements.

We analyse daylight levels, orientation and surrounding constraints to highlight any problem areas and support high-quality internal environments.

TM54 assessments provide a realistic prediction of how much energy a building will use once occupied.

By modelling real-world factors such as occupancy, system performance and weather, we help identify performance gaps early and support more robust energy-efficient design.

Energy and Carbon Statements outline how a development reduces energy use and carbon emissions in line with local planning policy.

We provide clear, compliant statements for residential and commercial projects, helping support planning applications and demonstrate a commitment to sustainability.
