Din, Asif and Brotas, Luisa (2016) The evaluation of the variables of overheating under TM52 and its impact on Life Cycle calculations of buildings: a strategy tool for designer. In: 36th International Conference on Passive and Low Energy Architecture. Cities, Buildings, People: Towards Regenerative Environments, 11th - 13th July 2016, Los Angeles, USA.
Overheating and its influencing factors in buildings are not understood by designers with both overheating and construction has a direct influence when air condition is adopted under future UK climate. Using TM52 the sensitivity of variables is studied to determine when air conditioning would be installed for various constructions. Air velocity, thermal mass and shading are the most influential mitigation factors against overheating but care is required to use realistic values within designs. Occupancy, Thermal insulation values and internal heat gains show a low amount of variance to the overheating result. TM52 criterion 1 matches closely the solar, construction and internal ventilation control influencing living room overheating incidents. Criteria 2 and 3 are influenced by the outdoor environment and determine when air conditioning is required for bedrooms. Designers should understand the implications of design choices for the lifespan of the building considered.
