| Abstract | ||||
| Electricity consumption of the Egyptian building sectors has an increasing rate from 2014 until now according to annual report for electricity ministry [1]. Hence, this research examines the common building envelope systems after increasing the thermal resistance of exterior envelopes to achieve high energy efficient buildings. That will be attained by: 1- field results for the case under study is used to validate numerical model. Then, the thermal performance for the case study is increased by exterior thermal insulation panels, reduced air infiltration through double glass windows instead of infiltrated single glass windows. 2-Three-dimensional numerical results - TRNSYS v17 program, which demonstrated that, only 0.35 m thick straw panels for the external walls, double glass windows with 1.5 m horizontal shading and 0.6 ach ventilation rate save 26.6 % cooling energy for the building under study. While 0.15 m and 0.2 m expanded polystyrene panels can save 24 % and 23 % respectively. | ||||
