Building Thermal Modelling

Thermal modelling can be used for a variety of purposes such as: –

  • Aid architectural and building services design
  • Help ensure energy efficiency
  • Help ensure thermal comfort for occupants

We can provide thermal modelling calculations and a thermal modelling report for legislation / guidance documents or for design analysis. Some of the uses include: –

  • Energy performance certificates and CO2 emissions
  • Building fabric thermal performance
  • Daylight calculations (such as BREEAM HEA01)
  • Natural ventilation strategies
  • Mechanical ventilation strategies
  • BREEAM assessment credits – HEA01, HEA02 and HEA04
  • Heating and cooling loads (CIBSE loads)
  • Summertime overheating
  • Plant sizing
  • Solar shading
  • Part L Criterion 3 solar gain
  • Building Bulletin 101 Ventilation of School Buildings (BB101)
  • Level 4 and Level 5 EPCs
  • Comparison of various building design strategies
  • CIBSE TM52 thermal comfort calculations
  • CIBSE TM59 domestic overheating assessment
  • CO2 concentration levels within rooms

Thermal modelling requires the same minimum input data that SBEM calculations and EPCs would, such as heating and cooling systems, hot water provision, ventilation and lighting information, as well as an accurate model of the building geometry.  However, it is then possible to add a huge amount of amendments to the building set up, in the form of occupancy profiles (operational hours and densities), plant profiles with heating / cooling set points, window opening strategies and solar shading control, such as mechanical blinds.
