| Abstract | ||||
| The main facade of buildings is the windows, through which light enters; they represent the link between the internal and external environment, where heat exchange occurs. This research reviewed several studies on double-glazed windows to determine their effect on the internal environment in terms of saving energy used in air conditioning and improving the temperature inside buildings. To achieve this goal, the researchers applied two techniques, the first one was changing the glass materials, and the other one was changing the windows design. In this review, the materials used in previous work were phase change material (PCM) such as paraffin wax, low-emissivity coating, colored glass, and air-replacement materials such as argon, which were added between the double-glazed panes. Regarding the design technique, the thickness of the air gap was changed, natural ventilation was used, and double glass windows with single and double rooms were used. The maximum improvement in temperature was 18.84°C when using double glass windows with low emissivity coating, and the best annual energy savings were achieved when using building integrated photovoltaic/thermal double-skin facades (BIPV/T-DSF), where the energy savings rate was 106%. This research review found that the amount of energy savings and improvement in temperature varies according to the direction of the building, thickness, and type of insulating material and glass type. | ||||
