Abstract
Students spend most of their time at schools in one space where it should be well lit and ventilated during the school day. Integrating daylighting within a school building is an important factor for a vital sustainable design. Daylighting is not only by adding windows, but it’s also by letting a good amount of daylighting into the classroom, putting into account to control the undesired sunshine radiations, it’s also responsible for increasing students’ attendance and improving their performance in a healthy IEQ. Many guidelines can be derived and established with reference to Practical experiences conducted by professionals in design and construction fields. This research is concerned with evaluating the school building envelope and its impact on the daylighting uniformity and sufficiency in the classrooms, and the possibility of saving electrical lights and cooling loads that can be reduced by the help of design elements such as glazing size and shape, building construction materials, proportions and ratios of various elements of the classroom. The motivation in this research is to assess classrooms of the dominant types of ministry schools in the UAE; to discuss the existing situation, then to implement potential solutions that can adjust the school to be a better space. Computer simulation was chosen as a method to conduct this research and analyze all models. All strategies were modeled and evaluated using IES-VE 2015 programme where parameters, configurations, models simulations and outcomes showed daylighting, artificial lights and electrical loads of 24 scenarios, then comparisons were tabulated in charts with respect to each of the additional 21 proposed aspects. A final scenario was created using the best results of each of the variable aspects evaluated before; to estimate the possibility of achieving an optimum case that has the best saving and performing characteristics with regards to the attracted research criteria.
