Master thesis addresses to ecological aspect of building’s sustainability, based on carbon footprint and embodied energy. Within the thesis are studied parameters of environmental aspect of sustainability for four different variants of a residential building. For different variants of the building (reinforced concrete, clay brick, structural steel and wood) are compared energy consumption and release of GHG emissions throughout the whole life cycle of the building. There is also demonstrated life cycle analysis with a BIM software.
At the beginning of the master thesis there are introduced the issues of the global warming and the importance of sustainable design. Followed by the short description of LCA methodology, which is used for an assessment of products and objects on environment. Further on there is introduced the building and its variants. There are made BIM models for each building variant, which are executed by using BIM software ArchiCAD. For various simulations and calculations is used ArchiCAD and its plugin Ecodesigner STAR, which are also presented within the thesis. Process of energy analysis is described in details. Obtained data of energy consumption and released emissions is used for a life-cycle assessment. That is followed by the presentation of calculated carbon footprint (embodied carbon) and embodied energy of a particular building variant. Input data of material’s carbon footprint is obtained from ICE database and ArchiCAD’s material library. After studied important phases of the building’s life-cycle there is shown a comparison of carbon footprint for different variants. At the end there are given some final conclusions of conducted study.
