Dynamic Thermal Modelling

Thermal Modelling by Dynamic Simulation, or Dynamic Thermal Modelling, is becoming more common to demonstrate the way a building will behave during summertime in terms of overheating and whether sufficient fresh air can be obtained when a naturally ventilated solution is preferred to mechanical ventilation.

In the same way building design has progressed over the years, so have the standards that govern them, Building Regulations have become more stringent and new environment standards have been introduced such as Breeam and LEED. Local governments also stipulate their own requirements to be met such as the London Plan (www.london.gov.uk/what-we-do/planning/london-plan)

BB101 (Building Bulletin issue 101)

Rules have also been introduced for different building types, such as the Building Bulletins for Educational Buildings (BB101).

There should be no more than 120 hours when the air temperature in the classroom rises above 28°C during occupied times. (for more information see our BB101 specific page)

BREEAM (Building Research Establishment’s Environmental Assessment Method)

BREEAM HEA04 Thermal Comfort goes a step further. The building should be designed to limit the risk of overheating, in accordance with the adaptive comfort methodology outlined in CIBSE TM52: The limits of thermal comfort: avoiding overheating in European buildings.


CIBSE TM59: Design methodology for the assessment of overheating risk in homes sets the standards which need to be met specifically for residential property.
