Abstract
Building envelopes play a major role in improving the overall energy efficiency
as well as in providing a healthy indoor air quality for occupants in office
buildings.
The notion of this research is to develop an integrated façade technology that
interacts and adapts with the changing climatic conditions, in hot arid regions, in
order to improve occupants’ thermal comfort in mixed mode office buildings
through the use of natural ventilation and evaporative cooling techniques,
thereby reducing mechanical cooling energy loads.
In this research, façade design decisions were based on two main computer
simulation results; thermal comfort levels and the reduction in energy
consumption. The authors propose a double skin façade system that consists of
an external skin which works on multiple operating modes. This skin integrates
passive cooling strategies with the building envelope depending on the data
collected by external and internal sensors. My previous investigations showed
that shading, natural ventilation and evaporative cooling are the most effective
passive cooling strategies for hot and arid regions
In conclusion, this research will contribute in reducing energy consumption
in commercial buildings, and help provide a productive work environment.
Keywords: passive cooling, arid regions, evaporative cooling, double skin
