Integrative approach for desert sustainable ecohouse design

Abstract

The study presents an integrative approach for desert sustainable architectural design that could be valuable to building professionals who might search for sound application models useful in harsh desert conditions. Following an integrated process of design and performance evaluation, a sustainable eco-friendly house was designed in light of Estidama guidelines, assessment method, and other design information documents (building codes, standards, and design guidance). The traditional courtyard form configuration was adapted and optimized to improve shading, natural ventilation through the courtyard assisted by wind towers to promote airflow, and special attention was also given to greenery and landscape elements to avoid heat and cool the house. All these systems were simulated and improved in order to achieve optimum energy performance. The design achieved considerable improvement over a typical Emirati house case; 59 % reduction in the greenhouse gas emissions and utility bill.
