Tiivistelmä
In the AEC industry energy analysis is becoming more and more relevant during the design stage due to the increasing regulation requirements for buildings globally, in the EU as well as in Finland.
Energy calculations are done mostly by traditional hand calculations and spreadsheets and are usually carried out only once, usually at the end of the design process and does not give room for a variety of alternatives. There is a growing need to forecast Energy usage during the design process and consider alternative energy conservative measures (ECM) and design considerations for a more energy efficient building. BIM can provide this possibility.
BIM has been adopted globally as the next trend in building production. Incorporating Energy Analysis is just one way of using BIM to create a seamless work flow. Autodesk as well as other software developers have created faster ways of analyzing energy in a building, and creating near seamless integration with BIM software.
This thesis researched the usability of the Autodesk BIM capabilities to conduct Energy Analysis of Educational buildings during the design phase. The aim is to integrate the use of BIM for energy analysis in the design process and optimize the case building to its possible energy and sustainability potential. The software used were Revit, a BIM software and Green building studio, a cloud based energy analysis program.
The results show that Autodesk Revit in combination with GBS can conduct energy analysis of a structure and analyze design alternatives that can lead to a more energy efficient structure. It can also simulate cost savings as a result of the alternatives. The use of BIM for energy analysis also has its own shortfalls. Accuracy of the energy model and data inputs can greatly affect the result obtained. Energy simulation results can also be affected by the level of complexity and size of the project.
