Abstract

This was a comparative, partial, life-cycle assessment of the energy and environmental impact of four exterior walls, with same thermal transmittance and thickness, in a hotel model placed in Athens, Greece. The assessed energy indicator was the sum of primary energy used in the construction and operation phases of the corresponding model scenarios. The environmental impact indicator was the carbon dioxide air emissions in the same life-cycle phases. The exterior opaque wall variants included: (a) a double leaf brick wall with cavity insulation, (b) a single leaf brick wall with external insulation, (c) a lightweight steel drywall with cavity insulation, and (d) a lightweight steel drywall with external insulation. Results indicated that the lightweight steel drywall with external insulation would be the optimum design choice. Both its energy use and carbon emissions resulted in 1.1% and 1.8% lower life-cycle values respectively than the average values among the four wall variants.
