; ;Dissauer, C.; ; 62 487 - PublicationComparison of different building shells - life cycle assessmentThe REACT (Renewable Energy & Efficiency Action) project is an EU-funded cross-border cooperative venture featuring the participation of companies and researchers from Burgenland (Austria) and western Slovakia that is developing zero energy concepts for newly built single-family homes. A variety of building structures are defined for family houses, and the different impacts they have on the environment are evaluated over the entire life cycle. This paper aims to compare the environmental impacts of different building shells during both the construction and the demolition phases. However, the operation phase of the building is not evaluated. One of the findings of the project thus far is that the demolition and disposal of building materials should be included in any such evaluation. For some environmental impact assessment categories, both demolition and disposal are important. The environmental impacts of various end-of-life scenarios can differ greatly based on the disposal method (e.g., landfill, incineration, recycling, etc.) chosen and on the proportion of recycled content. Furthermore, the results show that manufacturing building materials from renewable resources can have strong environmental impacts, particularly when substantial amounts of fossil fuel are required in their production.

The extent of integration of thermal waste treatment processes into regular energy supply systems plays a major role with regard to climate control. In this research, the specific waste management situation looked at scenarios aiming at maximizing the energy recovery from waste (i.e. actual scenario and waste-to-energy process with 75% energy efficiency [22.5% electricity, 52.5% heat]) yield greenhouse gas emission savings due to the fact that more greenhouse gas emissions are avoided in the energy sector than caused by the various waste treatment processes. Comparing dedicated waste-to-energy-systems based on the combined heat and power (CHP) process with concepts based on sole electricity production, the energy efficiency proves to be crucial with regard to climate control. This underlines the importance of choosing appropriate sites for waste-to-energy-plants. This research was looking at the effect with regard to the climate impact of various waste management scenarios that could be applied alternatively by a private waste management company in Austria. The research is, therefore, based on a specific set of data for the waste streams looked at (waste characteristics, logistics needed, etc.). Furthermore, the investigated scenarios have been defined based on the actual available alternatives with regard to the usage of treatment plants for this specific company. The standard scenarios for identifying climate impact implications due to energy recovery from waste are based on the respective marginal energy data for the power and heat generation facilities/industrial processes in Austria.
