Abstract:

This study encompasses a lifecycle carbon emission assessment methodology of buildings for four Iranian cities, each located in a different climate zone, namely Yazd (hot-dry), Bandar Abbas (hot-humid), Rasht (moderate-humid), and Tabriz (cold). Lifecycle emissions were quantified with the help of a Python-based tool at the construction, maintenance, and operational stages for ۵۰ years. The tool considers emissions by production of materials, transportation, energy use, heating, cooling, water heating, and maintenance. Furthermore, the role of photovoltaic systems is assessed regarding carbon savings, considering every city's different solar potential and climate-specific energy demands. Preliminary results show that operational emissions from energy use constitute the highest contribution of all the lifecycle emissions. The profile of the emission values also demonstrates significant differences in the energy use pattern, such as the high cooling demand of Yazd and Bandar Abbas, which is dominated by the heating demand from Tabriz. It also shows that PV systems can provide substantial carbon savings, especially under high solar irradiance conditions typical of Yazd's climate. This research highlights how climate-specific carbon management strategies might inform sustainable building practices within Iran and similar climate regions, offering hope for a significant reduction in carbon emissions from the construction industry by incorporating renewable energy solutions and building designs adapted to local climates.
