Klimatdata som mervärde i leverans till kunden : En parameterstyrd mall i Revit

Sammanfattning: The construction industry contributes to a large part of emissions and for that particular reason a new law about climate declarations will be enforced from the Swedish National Board of Housing, Building and Planning. Climate declarations present emissions for building materials, building parts or even for a complete building.  Climate data computed in climate declarations are based on life–cycle assessments (LCA). LCA describes environmental impacts which material has during its whole lifespan, from “cradle to grave”. An environmental product declaration (EPD) presents results from a life–cycle assessment in a more compressed matter.  Meanwhile the interest in sustainability increases, the automation within the construction industry continues, as well as various programs, which are being developed to obtain sustainability data. Construction companies do not usually present information containing climate data in their construction documents, therefore Geosigma Konstruktion aims to offer this information to its customers. This information can be provided by making one of BIM’s software programs – Revit more efficient and as well as integrating it with sustainability.  The purpose of this thesis is to generate climate data from a parametrically driven template, this can offer an additional value to the customers. This climate data displays values of emissions in a schedule format for framing materials. The schedules are created in the Revit program and are categorised after materials’ strength class, profiles, types and building parts within building constructions. A survey is also conducted and sent out to Geosigma Konstruktion's customers, in order to answer the questions in this study.  The results of this study show that the parametrically driven template with climate data will provide additional value for the customers. Furthermore, this template can be used as a basis while determining the structural framing.
