    Abstract

    New building energy standards have recently been proposed for Egypt. There is however insufficient data on the performance of existing buildings to provide a baseline for assessment of the impact of these new standards or other possible upgrade measures. In common with the rest of the world, there is also no standard design assessment method which takes account of the inherent uncertainty in operation, behavior, and weather. This paper first explores the current energy and environmental performance of offices in Egypt through a simple energy survey of multiple offices and more detailed investigation of an individual office building. The observed indoor thermal environment is compared against adaptive and non-adaptive thermal comfort standards. A method is then proposed for assessment of building performance which takes account of uncertainties in operation, behavior and weather through the definition and use of representative input parameter sets. The application of the method is illustrated for energy and thermal comfort performance of a typical Egyptian office building. The more general applicability of the method in design and policy, and potential for further developments, are discussed.
