The group has extensive experience in all forms of building physics energy analysis, relating to energy flows at both the detail level and the whole building scale using the latest sophisticated computer software and laboratory testing where appropriate.

Heat flow through building details can be determined using a variety of two-and three-dimensional conduction models to assess thermal bridging. Both steady state and dynamic modelling can be undertaken.

Hygrothermal (heat and moisture) analysis allows condensation risk to be calculated, from simple one dimensional problems up to complicated three-dimensional involving internal steel framing.

Whole buildings can be modelled using dynamic thermal simulation software and subjected to different climatic regimes to assess passive design strategies (thermal mass, glazing, shading and other fabric enhancements) internal comfort conditions and energy use.

Lighting simulation can be used to evaluate daylighting performance (daylight factors) and artificial lighting requirements for any combination of room geometries and surface reflectances.

In the laboratory, existing or bespoke test rigs can be used to test cladding panels and joints for air-tightness at controlled pressures, establishing confidence in their performance when installed. Other possible tests include thermal transmission measurement with calibrated temperature sensors and heat flux meters.
