Multi-objective optimization of building life cycle performance. A housing renovation case study in Northern Europe
2020
While the operational energy use of buildings is often regulated in current energy saving policies, their embodied greenhouse gas emissions still have a considerable mitigation potential. The study aims at developing a multi-objective optimization method for design and renovation of buildings incorporating the operational and embodied energy demands, global warming potential, and costs as objective functions. The optimization method was tested on the renovation of an apartment building in Denmark, mainly focusing envelope improvements as roof and exterior wall insulation and windows. Cellulose insulation has been the predominant result, together with fiber cement or aluminum-based cladding …
Comparison of the environmental assessment of an identical office building with national methods
2019
The IEA EBC Annex 72 focuses on the assessment of the primary energy demand, greenhouse gas emissions and environmental impacts of buildings during production, construction, use (including repair and replacement) and end of life (dismantling), i.e. during the entire life cycle of buildings. In one of its activities, reference buildings (size, materialisation, operational energy demand, etc.) were defined on which the existing national assessment methods are applied using national (if available) databases and (national/regional) approaches. The ?be2226? office building in Lustenau, Austria was selected as one of the reference buildings. TU Graz established a BIM model and quantified the amou…
Life-Cycle Assessment of Buildings
2019
The chapter presents a complete overview of LCA applied to buildings. After a brief introduction on the origin and developments of the LCA, it describes four steps of the LCA methodology, according to the framework of the International standards of ISO 14040 series. Then, the authors focus on the LCA applied to the building sector and on the standard EN 15978. They identify the main issues related to the application of the methodology to buildings, such as the selection of the functional unit, the systems boundaries,the environmental indicators, etc. In the context of the sustainability, a brief overview on the economic and social aspects of buildings and on the available building life-cycl…
