Night cooling is an established technique allowing ventilation to take place at night with the intention of removing heat gains that have built up during the preceding day. By permitting the cool night air to flow through a building, heat is removed and a store of the cool air within the building fabric, furniture and fittings is achieved thus providing a cooling effect the following day.
This report is the third in a series produced for project 11621 "Night Cooling Control Strategies". The first report was a literature review of night cooling techniques, the second report detailed the results from case study buildings that were monitored in 1995 and this report includes the results of dynamic thermal simulation. APACHE thermal simulation software was used to model a basic representation of one of the case study buildings.
The subject of this study was the indoor air quality of schools with natural ventilation in La Coruna (Spain). We took as reference the C02 H2O and CO contents of both the indoor and outdoor air. In both cases the monitoring was carried out over a 48 hour period using a photoacoustic infra-red spectroscopy multi-gas monitor. The outdoor air quality was seen to be good.
