Investigation of the effect of double skin facade systems on heating and cooling loads of the building for different climate regions

In recent years, there have been increasing and very important climate change problems. The building sector, which ranks first in the energy consumption worldwide and plays a leading role in the energy crises, has important responsibilities in energy conservation to compensate for its damages. The high consumption rates in the sector make it necessary to prevent these losses in buildings with energy-efficient strategies. The main purpose of the energy efficient structure design, which is an approach that emerges as a result of this, is to provide optimum indoor comfort by consuming minimum energy against outdoor conditions. The part where energy losses occur intensively in the buildings is the building shell that is in contact with the external environment conditions. Since the building shell, which plays an important role in determining the energy needs of the building, is the interface that is in direct contact with environmental parameters, it is the main component that energy-efficient design measures can be taken. Especially with the overcrowding of cities and the increase in high-rise buildings, the measures to be taken on vertical surfaces are largely effective in reducing building energy loads. The double-shell facade systems, which are designed to minimize energy losses caused by increased energy consumption and to make maximum use of the energy used, operate with the principle of ventilated thermal buffer zone with the space created between two glass layers. This buffer area also benefits from daylight while reducing heat loss in winter and excess heat gains in summer. In this way, it helps to increase the thermal comfort of the user by minimizing the energy consumption of the building as well as to provide sufficient lighting within the building. The aim of this study is to examine the effect of the double skin facade system on heating and cooling loads in buildings in different climatic regions. In this study, it is aimed to evaluate the current situation of the southern facade of a sample office building and the performance of 60 cm, 80 cm, 100 cm, 120 cm, 140 cm, 160 cm, 180 cm and 200 cm wide double skin facade situations in the selected regions to represent five different climate regions given in TS 825. In this direction, the heating and cooling loads of the building were calculated by preparing a three-dimensional model with the Design Builder software, which is an EnergyPlus-based software tool of the sample building. Thus, the double skin facade system was developed in Adana (1st Region), Balıkesir (2nd Region), Elazığ (3rd Region), Sivas (4th District) and Erzurum (5th Regional) provinces, the results are presented in comparative figures and tables.
