Digital workflow for sustainability-optimized and correctly climate-declared residential buildings

The goal is to develop a digital workflow that enables optimization of residential buildings for different sustainability goals and make sure that the climate declaration is representative for the final building. The project is supported by the strategic innovation program Smart Built Environment and is carried out in collaboration between Luleå University of Technology, WSP Byggprojekting and Kirunabostäder.

The Swedish government suggests a new climate declaration act from 1 January 2022 that requires declaration of greenhouse gas emissions from new buildings. Calculations of greenhouse gas emissions are usually produced by e.g. technical consultants through life cycle analyses (LCA). Today, the work is largely done manually and only with certain data in digital format, which is why it takes longer than necessary. It is also a challenge to ensure that the climate declaration matches the final building as late changes and deviations during production are difficult to capture.

In order to achieve the sustainability goals according to Agenda 2030, it is also important to be able to include other sustainability parameters than climate impact, such as low energy use in production and operation, low building costs and good daylight availability during the user phase.

The goals of the project are to:

• Develop tool and methods to be able to enable optimization of a building's sustainability performance
• Create proposals for digital work methods that support the production of climate declarations for buildings

The project is based on methods for automated design and optimization developed by LTU and WSP.
