Our Services

SAP assessments measure the energy performance and carbon emissions of residential buildings. They are required for new builds, extensions and conversions to demonstrate compliance with Building Regulations.

We produce accurate Part L1A and L1B SAP calculations to support compliance and help prevent delays at both design and completion stages.

SBEM assessments are required to demonstrate compliance for new or refurbished non-domestic buildings with a usable floor area over 50 sqm.

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

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

We provide both Simplified Method assessments and Dynamic Simulation Modelling to review glazing, shading and ventilation strategies and demonstrate full compliance.

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

Through Dynamic Simulation Modelling, we assess designs against CIBSE comfort criteria to identify overheating issues and recommend practical improvements.

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

We analyse daylight levels, building orientation and surrounding constraints to identify potential issues and support the creation of 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 - including occupancy patterns, 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 demand and carbon emissions in line with local planning policy.

We prepare compliant statements for residential and commercial schemes, supporting planning applications and demonstrating a commitment to sustainability.
