Digital environmental certification process by using BIM – models : A study on visualization of environmental parameters

Sammanfattning: The ability to enter in information about the building’s function in an open buildingmodel is admittedly not an innovative technology but in regards to those aspects ofwhich this project concerns - that is the building’s environmental performance interms of energy, indoor climate, and daylight— has knowingly not been explored. This thesis explores developing work processes as well as methods for working in acoordinated digital model with buildings environmental certification aspects. Thework emphasizes on the aspects of the environmental certification systems that arenormally examined using simulation tools, that being those aspects which pertain tothe building’s function, and whose calculated results are a determining factor for thebuilding’s design. A demonstration is presented to interviewees where threeindicators from Miljöbyggnad is visualized to identify the pros and cons with thenewly proposed method of working. The study shows that BIM is an interesting tool to use during the design phase. Thefact that the technology is advancing is nothing new, but the development of a moredigitalized environmental certification process should be considered. A visualpresentation provides a broader understanding of the working group and externalactors and is a favorable method to use during the project's workflow. The results from the interviews show that none of the companies use BIM as acomplement to the technical reports during the environmental certification process.The knowledge about BIM among designers and environmental coordinators is verysmall, however, there is great interest in the new proposed way of working. This study brings attention to the digitization of the environmental certificationprocess in a more efficient way, as well as a demonstration of the software Solibriand Revit that generate BIM during the environmental certification process. Theresults have shown that a visual presentation is a useful complement to the technicalreports but not good enough to replace them. The conclusion is that the new proposed working method cannot be implementedwithout the BIM-Link program. BIM - Link is a link that connects the results fromthe building simulation to the object-based model and the review tool. This programis not available as a test variant and this requires the purchase of a license.
