Abstract : The consumption of the energy in the world is in rise. However, without considering energy factors, this trade-off could hardly be maintained, therefore, increasing the demand for energy consumption that can lead to more harm to our environment. Commercial buildings are considered one of the largest buildings sectors and are responsible for over 50% of the total energy consumption of public buildings (Aksamija, 2013). It is believed that this percentage is much higher in many under-developed countries as in Saudi Arabia. In this work, we conducted a case study in Jeddah city to explore how to overcome this issue from the early stages of the design. We proposed a solution by identifying ideal WWR “window to wall ratio” to optimize building energy consumption in terms of lighting and cooling energy maintaining office comfort levels. In the experiment, we used a computer simulation to study the ideal WWR for four main orientations. We chosed a single private office space with a single exposed opening window wall. The space location is proposed in a multi-story office building for simulation purposes. The study used Ladybug and Honeybee software to obtain the required daylight levels (Lux) and cooling loads (kWh/sqm). To eliminate the number of simulations which takes a considerable time, We run the tests only on four days for daylight calculations of four Equinoxes and Solstices Months (20th March, 20th June, 22nd September, and 21st December) during typical office working hours (9:00 am to 5:00 pm). The research used Grasshopper software as a parametric tool, that enabled the study to explore around 11,340 tests on each orientation by using “Evolutionary Generative System”, to produce the ideal window openings for each direction, that eventually reduced 18% of energy required for cooling loads compared with the maximum size of windows within the same space, maintaining required daylight levels during the day.
