Norway is Entering a New Era of Climate-Conscious Architecture (theatlantic.com) 119

The European Union has a target of making all new buildings zero-energy by 2020, but in Norway, carbon neutrality isn't enough. From a report: A consortium in Oslo made up of architects, engineers, environmentalists, and designers is creating energy-positive buildings in a country with some of the coldest and darkest winters on Earth. "If you can make it in Norway, you can make it anywhere," says Peter Bernhard, a consultant with Asplan Viak, one of the Powerhouse alliance members.

Bernhard says Powerhouse began in 2010 with a question: Is it possible to not only eliminate the carbon footprint of buildings, but to also use them as a climate-crisis solution? It was a lofty goal. According to the European Commission, buildings account for 40 percent of energy usage and 36 percent of carbon-dioxide emissions in the EU. But after undertaking several energy-positive projects -- building a new Montessori school, retrofitting four small office buildings, building a few homes, and breaking ground on two new office buildings -- Powerhouse has found the answer to the 2010 question to be an emphatic "Yes." In 2019, the collective's biggest project to date will open to the public: Powerhouse Brattorkaia, in the central Norwegian city of Trondheim.

Norway is Entering a New Era of Climate-Conscious Architecture

  • Not every place on earth is so fortunate. If they can make it there they can make it anywhere seems a bit suspect, if you ask me.
    • Almost all power generated in Norway is from hydro; their capacity is something like 105% of their domestic requirement (and they have loads of room to increase that if needed). In that sense they are blessed.

      So in this case I wonder if the building is really using geothermal power, or if they are just storing heat underground and remove it when needed?

        As another commenter has pointed out, I was thinking of Iceland, not Norway... my bad. Still, not every place has an excess of hydroelectric power either, and the point still stands.
      • True, and but Norway also has some thermal, wind and tidal power. Norway's electric grid is connected to Sweden, Denmark and Holland. Despite that Norway produces 9.3 tons CO2 per capita (in 2014), which is more then EU average.
    • Uh-oh . . . that triggered an annoying and frightening musical thought in me . . .

    It's called a log cabin. Literally TONS of carbon are locked away for the lifetime of the structure. The more carbon you lock away in the form of trees, the more insulation and thermal mass you have as a result.

      Now you just need to build it five to ten stories high with fireproofed wood pulp bricks, include modern HVAC, fiber and telecom, water and sewage, other machinery, maintenance, storage with optional bomb and chemical shelter space, windows and roof that can take the storms. And develop a fire proofed cellulose-nitrogen foam for the insulation. Or something like that.

    • Logs do not have as high an R value as other materials we use.

      According to the DOE [energy.gov], a log has an R-value of 1.51 per inch, including the effects of thermal mass. Or about R-18 from one foot log walls. And 12 inch logs would be considered really, really, really damn big. The same report says a typical log wall with no windows is R-8.

      A 2x4 wall with basic fiberglass insulation is R-14. Spray foam can easily double that. 2x6 exterior walls are pretty common now, so that even more insulation can get shoved

        If your goal is to produce negative carbon, a 24" wall is a good thing.

        • Not necessarily. Two people can carry a 6" log to put it into place. A 24" log is going to require machinery, which is probably going to be burning some sort of hydrocarbon.

          There's the fuel burned in the forestry of lots of really damn big trees, which will take longer to grow than the wood used for conventional lumber.

          May still be a net sink, and way better than concrete construction. But someone would have to do the math vs conventional construction.

      I do live in Norway and we did have a simple log cabin, if you were living it in all year long the firewood would completely dwarf any materials in the walls. Making the walls thicker also means you have to sink a lot of energy into heating the walls before the cabin gets warm and it would still bleed out quite quick. The ideal insulating wall has a hot side and a cold side with as little as possible in between to transfer heat, ideally you'd have a vacuum but fiberglass or foam is practically as close as y

  • ...you can make it anywhere".

    A lot of people think that way. "Well it works here, so why doesn't it work over there?".

  • Norway could stop extracting and selling hydrocarbons? Who is worse, the user or the drug dealer? Climate conscious my ass.
    • Can you care to share how that would have even the slightest impact in our global carbon emissions? By refusing to sell oil from existing developed assets they would be doing little more than virtue signalling. But I'm sure it would appease the USA which would ramp up some exports.

  • Do the projected energy costs over the existing buildings use get paid back in savings by retrofitting?
    Are the new energy costs so large that new spending on retrofitting is the only way to keep the cost of energy low?
    How about getting low cost energy for everyone in Norway and not having to pay for "retrofitting"?

    Put that "retrofitting" money to some other better use? Like making energy low cost so existing buildings don't have to pay extra for new "retrofitting"?
    Low cost energy would be great for al
  • CA recently requires that all new buildings have so many sq feet of solar on their roof top. That is actually a horrible regulation since it really does not accomplish much, except take business away from local utility.
    Instead, they should have required that all new buildings of 6 stories and under have enough on-site unsubsidized AE to => the HVAC's energy usage. This way, it gives developers choices on where to spend, be it LED lighting or better, more insulation, better windows, and/or ideally a geo
