  • KVNF Regional Newscast: October 28, 2021

    Basalt Vista is the first net-zero affordable housing project in Colorado, based in Basalt. The homes are constructed in partnership with the county, the school district, and Habitat for Humanity. The homes are lined with solar panels and operate using only electricity. They produce, on average, all the energy that they consume and the utility costs to the residents are basically zero once the production begins to generate credits. Rather than prioritizing keeping building costs as cheap as possible, net-zero homes prioritize keeping the costs to maintain the home low.

  • How Zurich Blazed a Trail for Recycled Concrete

    Zurich, Switzerland's largest city, is paving the way for sustainable building. Concrete is a major contributor of climate change due to the process it requires to make it.

  • Pour Flush Toilets Eradicate Typhoid in Katunguru Village

    Katunguru village reduced Cholera and Typhoid outbreaks by building and transitioning to pour flush toilets rather than pit latrines. Pour flush toilets require just a five-foot pit, so waste water doesn’t mix with drinking water and are inexpensive to maintain. A user pours in water to flush the toilet through an S-shaped pipe. In addition to stopping disease outbreaks, residues from filled pits are used as manure and ash from kitchens are sprinkled inside after each use to prevent odors and dry up waste residues. Pour flush toilets are not constructed with wood, so they also minimize local deforestation.

    In many cities, rainwater is drained through "grey infrastructure" things like pipes, streets, etc. In some cities, this system is combined with the sewage system. Rainwater drains into the sewage system, is then cleaned, then emptied into the river. However, with strong storms some sewage systems overflow. A problem that will worsen with climate change. In Harrisburg, Pennsylvania, rain gardens are one solution to overflowing sewage systems. Cities like Harrisburg are turning to green infrastructure, things like rain gardens, roofs with gardens, and parks, to ease the burden on gray infrastructure.
