Digital miljöinformation i byggprocessen

This report is only available in Swedish. English summary is available in the report.

Summary

An uninterrupted flow of environmental information can be enabled by digitalization. For the actors in the building sector this can mean both new cost-effective business models to share environmental information between each other as well as increased quality of information through better traceability between products and the assessments of their environmental performance. In order to come up with an efficient and secure handling of environmental information in the building sector this project has investigated topics such as acceptance, responsibility, ownership, secretes, and availability of environmental data. We have also discussed how new incitements could be created in order to increase the uptake of digital environmental information in the sector. The digital building product declaration, eBVD, has been used as a case.

In the review of the construction materials manufacturers and construction industry's management of environmental information, the project has identified a process that is analogous to the starting point and often also in practice. This is partly demonstrated in how documents are usually drawn up, and partly in the attitudes to how information will be shared throughout the building process. At the same time, respondents consider that their own digital maturity rate is high. Regarding the flow of environmental information many actors await that someone else will take a first step that can then be followed. Many construction projects today include certifications of the completed building, which in some cases require written certificates from material manufacturers or projectors. This forces you into an analogous way of working, which counteracts the rest of the pursuit of digitization. Therefore, in order to avoid environmental requirements as an obstacle to digitization, it is important that the requirements can be met by commonly agreed formats and standards.

A recurring point when respondents described what is missing for further digitization is that there is a lack of comprehensive digital representation of both building products and working tasks in the construction process. Without for example common article id and standardized formats for transfer of digital information it becomes difficult to compile comprehensive environmental information. Since almost all companies in the construction process first and foremost want to sell units, build and manage real estate, it is also this standard business case that has to push the digital change for environmental information. Otherwise, environmental information will only be an extension that is not used optimally.

Although many respondents talk about the efficiency gains of digitization, they do not appear to be sufficiently clear in a shorter time perspective to drive the process. We have identified which values can be achieved (more efficient information transfer, administration, assessment, etc.) but have not been able to quantify this neither have we managed to identify any individual player who wants to/ can finance such a change. Thus, it can be concluded that the incentives exist, but are no clear enough to be viable. We however believe that clearer economic calculations of profits in terms of saved resources and time could make the efficiency incentives more viable. We also see that new incentives can arise if the industry succeeds in developing new business models that support the unbroken flow of digital environmental information. One way of doing this is to add services that aggregate and creates new values based on the collected digital information.

The project's key conclusions regarding incentives and business models for digital environmental information can be summarized in:
• High perceived own digital maturity but low digital interaction.
• In order to avoid environmental requirements becoming an obstacle to digitization, it is important that the requirements can be met by commonly agreed formats and standards.
• To take the next step, a common digital reproduction of products and work methods with common digital identities is required.
• The incentives for digitizing environmental information must follow the digitalization process for the whole industry.
• To develop new incentives for increased digitalization, different services could be added to help evaluate and aggregate digital information.
