“…For screening LCA, the EeBGuide proposes to include at least the building envelope, including exterior walls, windows, roof and floor slab, and the primary load-bearing structure. These components are cumulatively responsible for approximately 76% of the embodied impact on average [25]. For the simplified LCA of the EeBGuide, foundations, interior walls, building services, and surface finishes, should be added to the assessment.…”

Life Cycle Assessment (LCA) is considered as the most suitable way to assess the environmental impact of buildings. Due to its extensiveness and complexity, but also due to a lack of knowledge amongst architects, the LCA methodology is currently most often applied as a post-design evaluation and not used to support or optimize design decisions during early design stages. Therefore, this paper looks at possible solutions to apply LCA, including operational energy demand simulation, in early design from two different perspectives: design-oriented user requirements, derived from literature, a survey, interviews and a focus group with architects, and LCA simplification strategies based on a literature review. Both perspectives are discussed and merged into an evaluation framework that can be used to check the suitability of LCA-based environmental impact assessment (EIA) tools for use by architects during early design stages, but also to develop new design-supportive LCA-based EIA tools. In turn, this can contribute to an increased uptake of these tools in building practice.

“…Under 'sustainable construction' rather large amount of different aspects is meant. El Khouli et al [13] suggests to consider efficient use of material and energy resources, which pose no risk to health as main criteria. According to M. Pulaski [14] sustainable material must be durable, reusable or recyclable, biodegradable, locally manufactured.…”

“…In recent years, many studies have identified the use stage of a building as the stage with the highest environmental impact [2][3][4]. With the establishment of passive, low-and plusenergy houses, and in particular through the use of renewable energy sources, the main impacts of new buildings are often no longer in the use stage but as embodied impacts in the product stage [5][6][7]. For low-and nearly-zero-energy buildings, the share of embodied energy is 26-57% and 74-100%, respectively [5].…”

With the introduction of energy-efficient buildings, the importance of embodied energy in new buildings has become increasingly relevant to minimising the impact of climate change. This study compares two existing four-storey residential buildings: one building has a reinforced concrete (RC) structure and the other has a timber structure. The study’s aim is to find out which building components are responsible for the largest embodied impacts and whether there are differences between the two construction methods. The specificity of the wooden building is the combined use of solid and lightweight timber elements. The methodology consists of a general life cycle assessment (LCA) and a more detailed analysis of the product stage using the eco2soft software. The heating and cooling energy demand was calculated using the WUFI Plus software with recent regional climate data sets. The results show that for both types of construction in multi-storey buildings, it is not only the superstructure that needs to be considered, but also the floor structures, which have a major influence on the embodied impact. The timber building requires less energy to maintain the indoor climate within the set temperatures. As climate change has progressed rapidly in Austria in recent years, it is recommended that the standards for climate models be updated more quickly to allow realistic prediction of thermal comfort at the design stage.
