    Evaluation energy efficiency of the existing building by simulation program

    The poor thermal insulation properties of the construction are responsible for high energy consumption of existing building. Passive solar gain, air ventilation and also the ability to view the outside are providing by the building's windows which are useful multifunctional devices. Among the elements of the typical building fabric, glazing is responsible for the greatest energy loss due to generally high heat transfer coefficients (U values). The glazing types are the main reason that cause 60% of heat losing through the outer shell of the existing building. However, they mainly controlled demand for heating and cooling in buildings in winter and summer, respectively. Traditional window techniques tend to have low U-values that cause significant heat losses during the winter and gain unwanted heat in the summer. An existing building was selected in (Çorum Ticaret ve Sanayi Odası -Turkey) aiming to improve its energy efficiency by changing its glazing with new different types (Multi layered and low- e coating) of glazing an with others direction instead of the currently type used (single-glazing). The simulation program (Revit- green building studio) was used to estimate primary energy consumption of that building. Also, the simulation program was used to calculate the energy consumption of the existing building after the changing of its glazing by new different types (Multi layered and low- e coating) and by different orientations. Comparison was made by SPSS statistical analysis program between the results obtained for the new glazing types (Multi layered and low- e coating) and different orientations aiming to choose the best type of glazing and best orientation, which performed the lowest energy consumption levels. The changing of the glazing type with different orientations approved that the (triple glazing with Low-e) and (South-West-North) were the best type and best orientation to be used instead of the existing glazing type (single-layer) and all direction. The suggested type (triple glazing with Low-e) with a U-value of 0.15 W/m2 K, solar heat gain coefficient of 0.24 and visible transmittance of 0.51, was the most energy efficient glazing type. The used type was declare decreasing the energy consumption of the existing building up to (78%) of the initial energy demand. The improvement of the visual and thermal comfort of the occupants could be required by using unique glazing technologies through the qualifying the energy consumption of existing building.
