HighlightsThe existing building could consume up to 7.6 times primary energy compared to rebuilding a new building consumption.To find a balance between reducing primary energy and reducing environmental impact potential, building renovation could be an optimized choice.The renovated building could meet the current building energy code while preserving at least 80% of the original primary embodied energy.Avoiding demolishing could result in reduction of overall environmental impact potential by 48%.
AbstractA comprehensive case study life-cycle analysis(LCA) was conducted on a four-story National Register historic building with a projected 75-year life span located in Medina, New York. Three adaptive reuse options were compared: historic preservation, renovation, and new construction; six different energy performance targets were constructed and compared as well. The study comprises two parts: a life-cycle energy analysis and a life-cycle environmental impact analysis. In this life-cycle analysis, the building assembly group that consumes the most embodied energy was identified, related suitable renovation options were analyzed, and conclusions were drawn based on the results. The aim of the research was to address the balance between energy and environmental benefits and drawbacks for different adaptive reuse options. Four impact categories (global warming potential, ozone depletion potential, human health particulate potential, and smog potential) were measured and their correlation with primary energy demand was analyzed.
