Abstract
This study investigated three newly-built Central London schools, as part of the Building Schools for the Future programme, that employed natural, zonal mixed- mode, and mechanical ventilation strategies for the provision of pollutant expulsion and thermal comfort. The operations of the respective ventilation strategies were modelled for summertime overhearing, as defined by Building Bulletin 101: Ventilation of School Buildings (BB101), using thermal analysis software (TAS) in a 'medium-high' climate change scenario developed by the United Kingdom Climate Impacts Programme 2002 (UKCIP02). The rigour of the designed ventilation strategies were assessed in the warming scenario for the present day, the 2020s, 2050s and 2080s and the points at which they failed were identified. Other ventilation strategies were then devised and modelled to assess the possible adaptations that could be made to the existing situation for the alleviation of summertime overheating. It was determined that the use of cross-ventilation and split-duct systems, in conjunction with night cooling could prolong natural ventilation strategies till at least the 2050s without significant overheating. Furthermore, classroom geometry was also determined to have an effect on summertime thermal performance. Beyond the 2050s, comfort cooling was recommended as a low-energy hybrid solution to cope with increasing external temperatures, in line with the 'medium- high' warming scenario.
