| Abstract | ||||
| In the last few years there has been a growing interest in green buildings and there is a general movement towards a better sustainable built environment. Building owners, designers, and contractors always have to overcome a lot of challenges to fulfill building occupants 'needs and owner requirements while minimizing their harmful impacts on the environment, economy and society. (LEED) Leadership in Energy and Environmental Design has typified the attempt of the (USGBC) U.S. Green Building Council to perceive structures intended to accomplish prevalent execution in a few regions including vitality & water utilization. Given the emanant enthusiasm for improving structures' vitality productivity, specialists have created prescient physical and information driven models for vitality and water utilization. Even though the physical methodologies expecting to compute the vitality utilization conduct at the structure level are precise, the need of persistently assessing and assembling information for all the information parameters frequently makes these methodologies unrealistic in certain applications [1]. Increasing Number of Commercial and office buildings in Egypt that seeks to be rated by international rating systems. More than 17 buildings in Egypt are LEED certified buildings. In order to assess if sustainable buildings are performing as expected, a post occupancy evaluation (POE) framework was developed and implemented on 4 fully occupied Buildings for more than 1 year all of them are office buildings. POE Techniques were selected from literature review and international studies and was implemented on the selected case studies. The dataset includes water and energy consumption, feedback from building operation departments and Designers. The results showed different levels of variations in terms of energy and water consumption, LEED Certified Buildings have conjointly shown to be less Efficient over time in some cases. The findings indicate that LEED scoring system might generate skew savings expectations, as feedback is poorly taken into consideration. The objective of this study is to introduce an assessment method that investigates the correlation between LEED certification and the actual energy & water consumption by investigating a case study of LEED-certified Buildings in Egypt. | ||||
