Abstract / Description
The variables of the formulae used in TM52 (CIBSE, 2013) are not understood by designers who cannot evaluate potential overheating within concept stage designs. Guidance on how TM52 relates to usage and heat wave effects is lacking in current documentation. The paper evaluates occupancy profiles, level of control, level of insulation and Internal Heat Gains on overheating criteria. The base point temperature for bedroom usage is discussed and how TM52 can be modified to accommodate this condition. Previous studies have established overheating mitigation measures (ZCH, 2014) and within the study these have been evaluated on their effectiveness for the UK future climate.
Using available weather files a heat wave criterion is established and its significance on the TM52 protocol is explored. Simulation software is used to investigate sensitivity of key parameters within realistic bounds. Shading, thermal mass, air velocity and ventilation availability are the most important factors in the reduction of overheating events. Heat waves cannot be definitively categorised given current weather files and other factors require consideration. Overheating in bedrooms is mainly caused by heat wave instances. Buildings should consider overheating aspects at the design stage to ensure buildings are fit for purpose at the end of their lifespan.
