- Abstract
- (en) The main objective of the BTP1000 project was to design (and build) an office building (€coffice) that would comply to the PassivHauss principles, offer a very high comfort and integrate different sustainability features, but cost no more than a traditional building. In order to achieve those objectives, an integrated iterative design approach was followed. From the beginning of the project, all stakeholders and various building specialists contributed to the decision making process, and design alternatives where evaluated from various perspectives (e.g. energy performance, comfort, life cycle cost and impact,…). The present paper focuses on how life cycle analysis (LCA) and life cycle costing (LCC) were used to integrate environmental and economic dimensions in the design process of the building envelope and how the results influenced final design options. LCA and LCC studies first compared different types of façades. The best compromise between LCC and LCA results, practical implementation, and thermal comfort were then selected for implementation. Subsequently, parametric energetic simulation results (combining heating, cooling, lighting, and ventilation) were used as input for LCA and LCC studies in order to optimise the insulation level of the building fabric elements (outer walls, roof, ground floor, glazing). In conclusion, LCC and LCA were very useful in the integrated design process and results showed the importance of taking into account not only the energy use for heating and cooling, but also for lighting into the building fabric optimisation.
