Implication

Randomized trial compares environmental and economic impacts of retrofit versus NZEB reconstruction in traditional buildings, suggesting significant benefits for sustainability.

Key Points

This study aims to evaluate the economic and environmental impacts of two strategies for retrofitting traditional Swedish buildings.
Developed a Life Cycle Costing (LCC) and Life Cycle Assessment (LCA) model for analysis.
Applied the model to a case study of the röd stuga in Falun over 50- and 100-year horizons.
Assessed economic indicators like Net Present Value (NPV) and environmental impacts such as GWP100 and CED.
The NZEB reconstruction scenario reduces life-cycle environmental impacts by 20–25% in GWP100 and 45–50% in CED compared to retrofitting.
Conservative retrofit incurs lower global costs, although the gap narrows over a longer time frame.
Operational energy use is dominant in cumulative energy demand, while embodied impacts are significant in GWP.
