Analyzing the weather data and identifying feasible passive strategies
Key rules of thumb :
1 . Good natural ventilation can reduce air conditioning in warm but not very hot days , if combined with some passive cooling techniques and shade
2 . Sparse cloud cover and high radiation levels mean there ’ s good daylight potential but windows and glazing need to be shaded at all times 3 . Local plantations can help shade walls and improve outdoor micro-climate 4 . Long and narrow floor plan to facilitate cross ventilation
5 . Considering the low humidity ratios , evaporative cooling strategies are feasible to help reduce the indoor air temperature and induce comfort .
6 . Treated courtyard and stack effect to induce ventilation can aid both the indoors and outdoors .
