Abstract: Buildings are considered to be one of the considerable energy consuming systems and greenhouse gas emissions sources, and 14% of this energy is used for cooling. This paper evaluates the energetic benefits and CO₂ emissions of incorporating phase change materials (PCMs) on the facade of an office building under real weather data conditions for Izmir, Turkey for cooling. For this purpose, two situations, specifically the effect of the melting temperature (27°C, 32°C and 37°C) and the location of PCM (interior, middle and exterior of the wall) have been investigated for five months, from May to September. The results indicate that integration of PCM with a melting temperature of 32°C at the interior section of the wall in the hottest months of the year, namely June, July, and August reduce the related CO₂ emissions by 50.15, 122.339 and 121.727 kg CO₂ respectively, compared to the baseline configuration without PCM.
