Life cycle assessment of energy retrofitting: case study of an apartment building

Key Points

• This research aims to evaluate the environmental impacts of energy retrofitting in apartment buildings using life cycle assessment methods.
• Conducted life cycle assessment of energy retrofits in an apartment building in Saudi Arabia.
• Evaluated energy use reduction and greenhouse gas emissions before and after retrofitting.
• Assessed environmental impacts across 18 categories.
• Annual energy use decreased by 25.5% after retrofitting.
• Greenhouse gas emissions reduced by 28%, despite the use of additional materials for retrofits.
• Overall environmental impacts showed decreases across 18 life cycle assessment categories.
