Thermal Performance Analysis
We evaluate how façade materialsand system designs affect a building’s thermal efficiency, helping reduce heatloss and improve insulation performance.
Key services include:
- U-Value Calculations – Assessing thermal transmittance of façade systems in line with UK Part L and international energy standards
- Thermal Bridging Analysis – Identifying and reducing heat transfer through façade brackets, fixings, and structural connections
- Dynamic Thermal Modelling (DTM) – Simulating façade performance across different seasons and climate conditions
Condensation Risk Assessment
Condensation can lead to mouldgrowth, façade deterioration, and reduced insulation performance. We assesscondensation risks to ensure long-term durability and building health.
Our assessments include:
- Dew Point Analysis to identify potential condensation zones
- Surface and Interstitial Condensation Checks within façade assemblies
- Hygrothermal Modelling (WUFI) to predict moisture movement and long-term façade performance
All studies are conducted inaccordance with BS 5250 and international building physics standards.
Energy Efficiency Optimisation
We help improve façade designs toreduce energy consumption and support low-carbon building performance.
Key optimisation strategiesinclude:
- Solar Heat Gain Analysis (SHGC) to control solar radiation
- High-performance insulation strategies for improved thermal resistance
- Passive design integration including natural ventilation and shading strategies
- Energy modelling using tools such as IES VE, EnergyPlus, and TAS to estimate energy savings and carbon reduction
Compliance with Energy &Sustainability Standards
Our thermal analysis helps ensurefaçade systems comply with leading energy and sustainability regulations,including
- UK Building Regulations – Part L
- BREEAM and LEED certification requirements
- ASHRAE energy standar
- Passive House (Passivhaus) design principles
- EU Energy Performance of Buildings Directive (EPBD)
Solar Gain & DaylightingStudies
We analyse solar radiation anddaylight penetration to balance thermal performance, visual comfort, and energyefficiency.
This includes:
- Glare control strategies through glass specification and façade design
- Daylight factor calculations aligned with EN 17037
- Shading system optimisation, including louvers, brise-soleil, and façade overhangs
