Thermal Modelling

We use accredited thermal modelling software (by IES) utilised by accredited operators, which is specifically designed for the assessment of building performance.

Thermal modelling allows complex energy relationships that occur in buildings to be understood and quantified.

The following areas are some of the ways in which thermal modelling can benefit a project:

  • Demonstration of compliance for Building Regulation Part L at pre, post construction stage and first fit-out stage
  • Checking summertime temperatures of rooms which do not have comfort cooling. Results can show the number of hours over 280C or the more complex “adaptive thermal comfort criteria”
  • (EPC) Energy Performance Certificates for new and existing buildings. EPC are mandatory for a building (or part of a building) when constructed, sold, or let

Thermal Modelling can be used for any building, but is compulsory for buildings which have any of the following features:

  1. Night ventilation strategy
  2. Ventilation with enhanced thermal coupling to the structure
  3. Demand controlled ventilation
  4. Automatic blind control
  5. Atria

Demonstrating compliance for BREEAM credits. The following BREEAM credits are often demonstrated by Thermal Modelling:

Passive Design Techniques. Some examples are as follows:

  • Natural ventilation
  • Effect of thermal coupling to structure (e.g. exposed ceilings)
  • Ground coupling (thermal labyrinth)
  • Glazing area percentages
  • Orientation
  • Daylight analysis
