Innovative Environmental Solution for One Floor Existing Commercial Buildings Located in Hot Climate to Be Naturally Ventilated (Case Study at Ras El Bar, Egypt)

Abstract

Commercial buildings are high energy consumption buildings due to lighting system, cooling, and heating requirements (HVAC) for main corridors, shops, and other services. This research is offering an innovative environmental solution for one floor existing commercial buildings by retrofitting the design to be naturally ventilated which lead to reduce building energy consumption and Co2 production. This Research main concept is ventilating corridors and common spaces at one-floor commercial building naturally and achieving users’ thermal comfort even in the hottest day at summer.Research case study is one-floor existing commercial building in Ras El Bar, Egypt. Building model is constructed in Design Builder software to simulate building energy consumption in the current design as base case and compare different environmental solutions results with it to estimate the energy and Co2 reduction. Also, CFD simulation for different design proposals is simulated to guarantee comfort natural air flow inside the corridors for building users.In addition to visit to building site to measure temperature and wind speed by multi-functional anemometer in many focal points indoor and outdoor the building, to consider any missing data that could affect on the final decision.Finally, after simulating more than one solution, the study present solution that naturally ventilate the on-floor commercial building and achieved users’ thermal comfort at summer.
