OVERHEATING CALCULATIONS

This building regulation relates to the following types of new buildings (not conversions):

The aim of requirement O1 is to protect the health and welfare of occupants of the building by reducing the occurrence of high indoor temperatures.
In the Secretary of State’s view, requirement O1 is met by designing and constructing the building to achieve both of the following.
a. Limiting unwanted solar gains in summer.
b. Providing an adequate means of removing excess heat from the indoor environment.

This is completed via either a ‘simplified’ or ‘dynamic thermal modelling’. It is imperative that this is done before construction starts to avoid potential mitigation.

At Oakland Energy we offer both services and can help you through the process.
