Thermographic Surveys

Thermographic surveys use infrared imaging to identify variations in surface temperature that may indicate heat loss, insulation defects, thermal bridging or air leakage.
Our surveys help identify potential weaknesses in the building envelope, providing valuable information for improving thermal efficiency and investigating building performance issues. Thermographic assessments can support quality assurance during construction, refurbishment planning and investigations of existing buildings.

Thermal Comfort Assessments (CIBSE TM52 and TM59)

Thermal comfort is an important consideration in building design, particularly as rising temperatures increase the risk of overheating.
We undertake thermal comfort and overheating assessments using dynamic thermal modelling to evaluate how internal spaces are likely to perform under different environmental conditions.

Our assessments include:

These assessments help design teams consider appropriate glazing, ventilation, shading and other passive design strategies to reduce overheating risk while maintaining comfortable internal conditions.

Daylighting Calculations

Access to natural daylight contributes to occupant comfort, wellbeing and the overall quality of internal spaces.
We undertake daylighting calculations to assess the availability and distribution of natural light within buildings. Our analysis helps architects and design teams understand how building orientation, window placement, glazing specifications and surrounding structures influence daylight performance.
Daylight assessments can also support sustainability certification requirements, helping projects balance natural lighting, thermal comfort and energy efficiency.

Operational Energy Calculations (CIBSE TM54)

Understanding how much energy a building is likely to consume in operation is essential for managing energy costs and reducing carbon emissions.
Using the CIBSE TM54 methodology, we assess predicted operational energy consumption, considering building services, occupancy patterns, equipment and other energy uses that may not be fully represented in standard regulatory calculations.
Our operational energy assessments help clients establish realistic energy performance expectations, identify opportunities for improvement and make informed decisions throughout the design process.

Net Zero Carbon (NZC) Calculations

Achieving net zero carbon requires a clear understanding of a building’s energy demand, associated carbon emissions and opportunities for reduction.
We provide net zero carbon calculations and assessments to help clients understand the operational carbon implications of their buildings and evaluate potential pathways towards lower-carbon performance.
Through energy modelling and carbon analysis, we support design decisions that prioritise energy efficiency, reduce operational emissions and contribute towards wider sustainability and net zero carbon objectives.
