A new breakthrough era in design has begun in whole building industry, which is based on BIM – Building Information Model. The emphasis of the new workflow is in information stored inside building model which is used in BIM-based software from where all designers get the needed data and work on. A change from designing on paper to designing in CAD (Computer Aided Design) software was a big change, although it actually just changed the normal paper with digital one. While on the other hand BIM is said by many to be a much bigger change in the way things work in building industry. The thesis focuses on the possibilities of BIM in building design regarding buildings’ energy efficiency and sustainability, which is becoming more and more important nowadays because of the climate change. There are many BIM software providers, but currently the most popular of them all in worldwide comparison is Revit from American corporation Autodesk. Software package contains three applications – Revit Architecture (for architects), Revit Structure (for structural engineers) and Revit MEP (for MEP engineers). There are many other specialized software applications which can work with Revit, but when we are considering sustainable design there are two programs from Autodesk which stand out – Ecotect Analysis and Green Building Studio (GBS). The thesis outlines history and development of BIM design and stresses out the importance in possibility of software interoperability and plots the basics of sustainable design in BIM. After that, description of modeling reinforced concrete structure of chosen building is shown in Revit Architecture 2010. The first goal of the thesis was modeling a whole detailed architectural model of the building, but when we realized the importance of using sustainable design analysis software is in the conceptual phase of design, we dropped that goal. The thesis then shows how a conceptual design of the building is modeled and then used in further study inside Ecotect Analysis 2010 and GBS. The study in Ecotect shows average daily insulation analysis and overshadowing of the building. GBS’s study shows possibilities and results of VII
