A combination of data analysis and computer simulation has been carried out to investigate the effects that UK heat waves have on naturally ventilated, highly insulated buildings. The work originates from the hypothesis that an increase in insulation levels in modern design and construction (to reduce energy, costs and carbon emissions) has the potential to cause detrimental effects on the internal environment.


The building studied is a newly constructed, naturally ventilated secondary school in the UK. Dynamic thermal simulation software was used to model the school using a Design Summer Year and morphed data based on data collected from site. Measured data and simulation results were compared to validate the model which was then used to explore the effects of future, higher temperatures.


The study demonstrates how naturally ventilated, highly insulated buildings risk overheating or could lead to the need for hybrid/mechanical ventilation to manage hotter periods of the year.
