The Directive 2002/91/EC of the European Parliament requires member states to calculate the energy performance of buildings with the overall goal of reducing their energy consumption. Additionally, the 2008 EU climate and energy package demands Austria to decrease the greenhouse gas emissions by 16% and increase the share of renewable energy sources by 50% till 2020 (basis 2005). Subsequently, the 2010 Austrian energy strategy EnergieStrategie Österreich aims to reduce the energy consumption due to building heating and cooling by 10% till 2020 (basis 2005). As a consequence the software industry developed tools that allow the calculation of building energy efficiency. Existing tools provide good results in calculating the energy level of a given architecture but fail to support the user in the subsequent step ¿ the identification of strategies on how to improve the building¿s energy efficiency (considering financial, legal, technical and individual requirements and constraints). The manual identification of the optimal building configuration is not only tedious but very costly for the user and, therefore, sets a major entry threshold for improving building energy efficiency. The overall goal of the research studio SEMERGY is to support ongoing EU and Austrian energy saving initiatives by developing a decision support system that enables stakeholders to efficiently identify potential building configurations with regard to (i) environmental impact, (ii) energy consumption for operating the building, (iii) energy used at the production and distribution of building components, (iv) financial constraints, (v) building component compatibility, and (vi) legal requirements. The stakeholders of the project results are (i) professional building planners that use the results as an extension to existing professional energy performance software to efficiently provide their customers with building configuration options that meet a given energy level and user-specific requirements, and (ii) consumers that use a web-based version of the tool to experiment with different building configurations and their influence on attributes such as initial costs and environmental friendliness. The early involvement of major stakeholders, such as Umweltbundesamt, A-Null, Zehentmayer Software, Theobroma, and Exikon, will ensure market relevance and successful exploitation of the SEMERGY project results. SEMERGY combines the latest Building Information Modeling (BIM) technology with semantic technologies (ontologies), which provide cost, energy efficiency, compatibility, and environmental impact data on building components and allow interpreting relevant legislation automatically. An interactive decision support mechanism (i) suggests the stakeholder efficient strategies on how to close the gap between the status quo and a better energy performance level, (ii) considers the users¿ individual preferences (e.g., financial, energy efficiency) and given constraints (e.g., legal, compatibility) and (iii) identifies the optimal set of specific construction products to implement the selected strategy. The provision of computational support for the buildings¿ design phase benefits the AEC (Architecture, Engineering, and Construction) stakeholders in view of cost reduction, energy efficiency, and occupants¿ comfort and productivity and, thus, reduces the effort for the design of energy efficient buildings
