Overheating Risk Analysis

Changing environmental conditions, construction techniques and behavioural factors has led to an increased need to consider mitigation measures for preventing overheating in buildings.

What causes Overheating?

Factors which can cause overheating:

  • Rising temperatures
  • Increased occupant densities
  • Community heating pipework losses
  • Lightweight building fabric
  • Airtight construction

Although solvable in many cases, this is a problem that needs to be addressed at the earliest possible opportunity in the design process.

Overheating Standards – CIBSE Guide A & Technical Memorandum 52

Significant industry research has been carried out over recent decades into the cause and effects of overheating and thermal discomfort. This has resulted in several standards to help assess building performance and define acceptable temperature thresholds.

CIBSE Guide A has set the recommended performance standard in the UK for many years, for both air conditioned and free running buildings. The latter has since been superseded by Technical Memorandum 52 which develops on the Guide A standard to also account for the fragility of the occupants and human adaption to sustained high temperatures.

In all cases, computational simulation is undertaken to predict internal temperatures resulting from the building design, occupant use and local weather environment.
