Emily Niehaus was working as a loan officer when she see realized that there was a need for affordable, sustainable housing options in her community. So she founded Community Rebuilds – a nonprofit that teaches people to build affordable homes out of “dirt cheap” materials like clay , straw and soil . Interns participate in a 5-month program, completing two homes from foundation to finish using sustainable living principles. Community Rebuilds started in Moab, UT as a way to ease the financial strains of people living in the community. Since then, the project has spread to southwestern Colorado and the Hopi Reservation in Arizona. The initiative has constructed 25 homes in four communities with the goal of expanding knowledge about valuable natural building skills across the US. Homes are built out of natural materials like straw, soil and clay using passive design techniques. They are equipped with green tech like solar arrays and sustainable features like adobe floors, earthen plasters and greywater systems.

Interns build two homes from the ground up. In exchange for their labor they get housing, food and an invaluable education in sustainable building. + Community Rebuilds

Designed by Santiago-based B+V Architects , the Folding House in Las Cabras, Chile was strategically wrapped with a wooden “flap” to give the owners optimal temperature control. The unique feature prevents excessive solar radiation during the searing hot summer months while inviting the heat in winter. In addition to providing year-round temperature control, the responsive design element pulls double duty as a sun-streaming cover for the rooftop deck, which offers spectacular lake side views. The stunning 900-square-meter home was tucked into a steep incline, exposing it to the area’s high temperatures. To create a responsive design that wouldn’t sacrifice aesthetics, the architects added the double-ventilated wooden façade as an attractive and protective element. The feature allows the homeowners to enjoy the amazing lake views year-round from the comfort of the outdoor deck, without overheating in the summer months.

In summer, the wooden facade acts as an eave that protects the home from excessive solar radiation . During winter, on the other hand, the wooden envelope allows heat to enter the interior, which is stabilized by high-quality insulation , as well as elimination of all thermal bridges. For additional heating on cloudy days, a small wood-burning stove can be fired up. On the interior, large floor-to-ceiling windows flood the home with natural light and also enhance cross ventilation when opened. A large open courtyard sits in the center of the interior, seamlessly connecting the exterior with the interior. + B+V Architects Via FlipBoard Photography by Rodolfo Lagos Berardi Images via B+V Architects

Wind energy supplied all of Denmark’s power needs one day last week

Comments Off on Wind energy supplied all of Denmark’s power needs one day last week

Renewable energy can generate enough power for entire countries–a fact Denmark can confirm. Last week on Wednesday, the nation met all of its power needs via wind energy , according to information from wind power trade organization WindEurope . The group said the energy Denmark produced from onshore and offshore wind was sufficient to power 10 million European Union (EU) households. Denmark produced 27 GWh via offshore wind and 70 gigawatt-hours (GWh) via onshore wind on February 23, according to WindEurope. This isn’t the first time wind power has achieved renewable energy feats in the country; 2015 saw several big days for wind energy. By the end of that year, 1,271 megawatts (MW) of offshore wind and 3,799 MW of onshore wind was installed in Denmark, amounting to a little over five gigawatts (GW) of wind energy. Related: Germany generated so much renewable energy last weekend electric prices went negative The industry did experience a slight slump in 2016, owing mainly to low winds. Before that year, Danish Wind Industry Association CEO Jan Hylleberg said since 2008 they’d “experienced continuous growth in the wind energy production and each year set a new world record.” Although the industry expected the trend wouldn’t continue in 2016, Hylleberg said the fact they didn’t maintain that upward movement was frustrating, but it appears 2017 is off to a soaring start. MHI Vestas Offshore Wind ‘s new nine MW wind turbine already smashed the record for energy generation in a 24 hour period during testing at a test field off Denmark’s coast. Hylleberg described Denmark as world champions at harnessing wind. But the Nordic country wasn’t the only nation to obtain a large amount of power via wind energy last week. WindEurope also reported Germany and Ireland respectively met 52 and 42 percent of their electricity needs with wind. According to the organization, “Wind power in the EU as a whole covered almost 19 percent of the bloc’s electricity needs.” Via CleanTechnica Images via Wikimedia Commons ( 1 , 2 )
