The meeting was the first of a series of breakfast seminars organized under the auspices of Klimavennlige bygg Innlandet. The meeting opened with a briefing on the project, and Eivind Selvig spoke on the topic What is a climate-friendly building? There are no clear answers to the question, but the goal must be for the building to have a significantly lower climate footprint than those built according to “normal” practice. <\/p>\n

– The climate-friendly buildings use materials that have a low climate footprint, including reuse. Energy consumption should be low and the proportion of renewable energy must be high. In addition, emissions at the construction site, the choice of building land and location with regard to transportation have a lot to do with the total,” Selvig explained. <\/p>\n

Climate Friendly Buildings Innlandet has chosen to emphasize climate-friendly material choices, although it is the sum of all the focus areas that will contribute to the overall goal: to reduce CO2 emissions in the Norwegian construction industry and help to achieve national climate goals and the goals of the Paris Agreement.<\/p>\n

At the meeting at Bylab, three players were brought in to talk about their work on the newly opened Drivkrafthuset in Hamar. The 13,000 m2 building was completed in November 2023 after an impressive construction period of just 22 months. The developer Utstillingsplassen Eiendom, tenant Eidsiva and contractor Betonmast Innlandet all have clear ambitions for sustainability, including greenhouse gas emissions. This was reflected, among other things, in the use of environmentally friendly, purified environmental concrete, which produces 75% lower greenhouse gas emissions than traditional concrete, and the use of robust materials throughout. The eco-concrete’s low emissions are partly due to the addition of reused excavated material that has been washed, cleaned and sorted. The building will be certified as BREEAM Excellent and has calculated greenhouse gas emissions from materials that are at least 20% lower than the reference level achieved. It has energy label A and is built as a passive house with a leakage rate of 0.3. The building is connected to Eidsiva Bioenergi’s district heating system for space heating, hot water and space cooling (absorptive cooling). The district heating was also used for building drying. There is also a photovoltaic system on the roof. <\/p>\n

Over the next few weeks, similar breakfast seminars will be held at<\/p>\n
