Quantification of the impact of the end-of-life scenario on the overall resource consumption for a dwelling house

摘要: In this work, fractions that are the result of demolition phase a dwelling house have been investigated with respect to their recovery potential: stony material, wood, metals, glass, synthetic materials and rest fraction. Depending on nature, different alternative end-of-life scenarios replace disposal, such as re-use, recycling or incineration heat electricity production. All resources necessary for these inventoried. At same time, those not longer disposal would make obtained products from virgin quantified. Based three items, overall balance results into calculation net resource savings scenarios, quantified in Cumulative Exergy Consumption (MJ exergy). For specific case, best scenario can save natural content 258 GJ exergy. Looking at entire life cycle house, i.e. construction phase, use quantitative analysis shows saving 15% implementation instead end-of-life.
