Could This City Be the Model for How to Tackle the Both the Climate and Housing Crisis? (npr.org) 71

NPR looks at the "high-quality, climate-friendly apartments" in Vienna, asking if it's a model for addressing both climate change and the housing crisis.

About half the city's 2 million people live in the widespread (and government-supported) apartments, with solar panels on top and very thick, insulated walls that reduce the need for heating and cooling. (One resident tells NPR they don't even need an air conditioner because "It's not cold in winter times. It's not hot in summer times.") Vienna council member Nina Abrahamczik, who heads the climate and environment committee, says as the city transitions all of its buildings off planet-heating fossil fuels, they're starting with the roughly 420,000 housing units they already own or subsidize.... As Vienna makes an aggressive push to completely move away from climate-polluting natural gas by 2040, it's starting with much of this social housing, says Jürgen Czernohorszky, executive city councilor responsible for climate and environment. City-owned buildings are now switching from gas to massive electric heat pumps, and to geothermal, which involves probing into the ground to heat homes. Another massive geothermal project that drills even deeper into the earth to heat homes is also underway.

The city is also powering housing with solar energy. As of a year and a half ago, Vienna mandates all new buildings and building extensions to have rooftop solar. And Vienna's older apartment buildings are getting climate retrofits, says Veronika Iwanowski, spokesperson for Vienna's municipal housing company, Wiener Wohnen. That includes new insulation, doors and windows to prevent the city's wind from getting in the cracks. The increase in energy efficiency and switching from gas to renewables doesn't just have climate benefits from cutting fossil fuel use. It also means housing residents are paying less on electric bills...

With city-subsidized housing, housing developers can compete to get land and low-interest loans from the city. Officials say those competitions are a critical lever for climate action. "As we can control the contents of the competitions, we try to make them fit to the main goals of the city," says Kurt Hofstetter, city planner for Vienna, "which is of course also ecological...." Now the housing judges give out points for things like increased energy efficiency, green roofs and sustainable building materials... Now the climate innovations in subsidized housing are inspiring the private market as well, Hofstetter says...

The article notes that most of the city's funding is provided in the form of low-interest loans, according to a researcher at the Austrian Federation of Limited-Profit Housing Associations. (And the average social housing rents are about $700 for a large one-bedroom apartment, says Gerald Kössl, researcher at the Austrian Federation of Limited-Profit Housing Associations.)

    • No idea why this gets downvoted. In many parts of Europe, cities are becoming or have become uninhabitable for normal people because rents and real estate prices are absurdly high. In some places, rental housing is either so scarce or so expensive or both that someone who wants to move there would be better off buying a flat or a house, which again is impossible for normal earners. That's why more and more people are demanding to illegalize vacant rental apartments and banning Air BNB and similar businesses

          I'd like to run my next house off solar but based on my experiments over the last couple of years we'd need at least 60kWh of batteries to cover the cloudy days in winter and even then we'd need to limit non-essential power usage until the sun came back because some days we get negligible power from our existing panels for more than two days at a time.

        How on *earth* does solar end up being so absurdly priced? A UK house can get solar installed, soup to nuts, for well under $10k, including scaffolding (typically a significant part of the cost here in the UK). 65k USD would buy you enough for more than four houses! And 54k usd of batteries would be like a 90kWh battery here -- which is gigantic and totally unnecessary for a home setup.

          what fraction? A large NZ solar retailer claims around US$7k install cost for a 5kW system; a presumably neutral news site (rnz.co.nz) says it's about NZ$2k per kW currently so that roughly checks out.

          I'm quite surprised genuinely if these numbers are real. Having central AC, switching to a hot water heat pump last year, and probably buying an EV in next couple of years - with the retail price increasing - I've been thinking about this more and more...

            My fraction would be less than half what he is claiming. I forget the total, I did it in two steps. I think it was around NZD $80K in total for 12kW of panels, a pair of 5kW inverters and a pair of Gen 2 Tesla Powerwalls for 26kWh of storage. I went with more expensive solar panels as the cheaper ones where only rated for 160kmh wind and I'm near the west coast north of Wellington. The system was from Harrisons and should be significantly cheaper now.

The problem was that was a solar+battery system that would cost more than th

      It's not an on-off switch, though: the Viennese approach here becomes less effective in more extreme climates, but it doesn't become wholly ineffective in most climates. It's still better to use thick walls in almost every climate, midrise urban housing offers a great balance in almost all cities between density and liveability, and rooftop solar is spreading like wildfire in much hotter climates eg Pakistan, sub-Saharan Africa, because the economics are so compelling.

TFA is in Europe, so here is the situation here: car fuel is 2-3 times more expensive than in USA, entirely due to taxes. It's not an easy decision to increase further beyond, it is already understood as a tax on the poor (who can't get better cars).

      Pricing out the demand side of mobility is a great way of turning your city / country into a crime ridden hellhole. Nothing good has come from regressively punishing the poor for the whims of the rich. If you want to stop people driving ICE cars then the solution is not to tax ICE cars, but rather to build systems of transport that offer an alternative to owning the thing. Vienna didn't get to be on the top of most liveable cities list (continuously for the past two decades) by trying to tax away problems, they did it by investing in social systems, they did it by creating more pleasant walking spaces and cycling infrastructure, they did it by building on of the most comprehensive and best public transport systems in the world - the type where you are connected to the city regardless of how far out in the suburbs you live.

      My grandma literally used to live in the last house in Vienna, "am Arsch der Welt" (translated on the arse of the world) as we called it because at the end of her street was a sign saying Vienna with a red line through it. Yet every time I landed at Vienna airport (which fun fact is not even in the state of Vienna), I had zero difficulty hopping over there with public transport. She's passed now but I still have family there. Family like my cousin, who at 40 years old doesn't have a drivers license because he simply doesn't need one.

      That's how you can reduce car dependency.

      As for taxing flying, you're deluding yourself if you think that solves a problem. Flying now is cheaper than it ever has been, but even in the expensive days of old billions of people flew around the world every year. I'm flying to India shortly.
