Studying Energy Consumption in Built Educational Spaces with Approach of Sustainability and Optimization

Sustainable architecture is one of the important developments in the field of architecture, and its purpose is designing based on optimization of energy consumption and sustainability principles. today, one of the tools available to check and optimize different parts of a project is the use of computer simulations, which can bring the project as close as possible to sustainability indicators in the design stage. in this article, as an experimental example, firstly, the space and structural features of one of the classes of azad university, hashtgerd branch, were modeled with the help of grasshopper plugin and energy and also light simulations were done by ladybug and honeybee add-ons. considering the fact that the project has been built, it is more difficult to make changes in it and they must be applicable. the variables considered in the simulations are: applying insulation on the walls from the inside, changing the type of windows to double-glazed and low-emissivity, applying shades and changing the type of air conditioning system. analyzes show that applying internal insulation to the walls and changing the type of window to a low-e double-glazed window will reduce energy consumption in the heating sector by 12%, in the cooling sector by 17%, and using smart lighting systems will reduce energy consumption by 28%. furthermore, the option of changing the air conditioning system and applying shadings is completely rejected, based on the results of the simulations.
