Accurate simulation of new glazed facades with emphasis on daylighting and energy optimization (Case study: office building in Hamedan)

Nowadays, The need to optimize energy consumption and seek to reduce its consumption is a vital issue. In this regard, one of the solutions is to use daylight and its lighting in the interior of buildings. However, in glazed envelopes the most energy loss. The choice of a suitable complex fenestration system (CFS) for glazed envelopes is very important. nowadays, using accurate simulations can calculate daylight performance and energy very accurately. Simulations of complex fenestration systems in a model to adapt to the impact in terms of daylight performance and energy consumption are complex and challenging. This paper seeks to optimize the performance of matrix-based annual daylight and climate-based energy consumption for various complex fenestration systems in the office building of Hamadan. This has been done on 14 simulations of glazed systems different from 8 groups of complex fenestration systems: Gas Fills, Low-Emittance Coatings, Multiple panes, Special Products, Tinted Glazing, Reflective Coatings, Glass Coatings and Tints in Double Glazing, Thermochromic glazing. The results of optimizing the criteria of annual daylight performance and energy use intensity show that the Low-E3 system is the most optimal example for the climate of Hamadan.
