36th AIVC Conference " Effective ventilation in high performance buildings", Madrid, Spain, 23-24 September 2015.
An experimental analysis of the night ventilation technique for cooling in buildings, was performed in a test cell with the aim of establish the potential of this technique in two scenarios: a) when the air-stream is in poor contact with the thermal mass and b) when the air-stream is in close contact with the thermal mass of the test cell. The test cell is a small one-room building equipped with instrumentation for measurement and control the night ventilation following a strategy based in the values of indoor and outdoor temperatures.
The results showed that similar mean daily temperatures are reached when the air stream is in poor contact with thermal mass and when is in good contact. Nevertheless, lower variation in the interior temperature is obtained when the air stream is in good contact with thermal mass, producing better comfort conditions since no very high and low temperatures are achieved in this case.
