Abstract

Opaque and transparent material are always influential factors in regulating the temperature in buildings. The variables considered in this research are transparent material as the type of windows and non-transparent material as covered materials on exterior layer of external walls on a case study in a hypothetical building in Tehran. Engineering details of Base model is chosen according to approval Tehran construction engineering organization. Six different types of windows including single layer, argon, air double glazed and triple layers with or without LOW-E cover and 11 common types of materials including ceramic, aluminum composite tile, polished and ordinary travertine, granite, black And white marble, refractory brick, red brick, 3 cm yellow brick, concrete are studied and their energy consumption calculated by simulation in honeybee and ladybug. Interaction of opaque and transparent material is investigated. Different results are compared with using Colibri and through the design-explorer website. Assortment of opaque material is introduced due to type of windows for optimizing energy consumption. The results show that energy consumption is diminished about 13% when double glazed air LOW-E and polished travertine are used compared to the base model.
