SOLID PARTS AND FENESTRATION IN BUILDING ENVELOPE ARE THEY WORKING IN SERIES OR IN PARALLEL UNDER CLIMATE CHANGE - STUDY IN EGYPT

Abstract

Abstract:This paper presents a comprehensive evaluation for the results of a recent research effort concerning thermal comfort in residential buildings in Egypt. Thereby, the energy performance and thermal comfort were considered based on the instructions of the Egyptian Residential Energy Code to improve the efficiency of energy use. The conclusions of the aforementioned research on the building envelope (walls / fenestration) were tested together to make sure that the use of what seems to be the best solutions for external walls (solid part) in addition to the best solutions for fenestration (openings), will results in a better overall performance in energy consumption and thermal comfort, than implementing one of the two choices without the other. To attain that, two HVAC case study buildings were dynamically simulated in three dominant Egyptian climatic zones, using current climate conditions (2002) in addition to three other morphed climate change scenarios (2020, 2050 and 2080). Achieving the required rates for thermal comfort, as well as acquiring long term financial gains, both were the basic elements of evaluation. The results provide what seems to be a functionally and financially successful combination to fulfil the evaluation elements.
