How a Small Net-Zero Energy Library Got the World’s Attention

How a Small Net-Zero Energy Library Got the World’s Attention | Sustain Our Earth | Scoop.it

The Valatie Free Library is a small library with plans to make a big difference. The threshold for defining a “small library” in the United States, according to LJ’s Best Small Library in America Award, is a library serving fewer than 25,000 people. The Valatie Free Library serves just over 4300 people and currently does so in a 750 square foot library building. Now that’s small!

Hungary's Odooproject prefab home produces twice the amount of energy it consumes

The prominent south-facing wall features a considerably large surface area that is entirely fitted with photovoltaic panels. During the summer months when the sun is high, solar energy is produced by the roof panels, while during the cooler months when the sun is lower, energy is produced by the south-facing wall. “Ultimately, owing to this system, the house generates twice as much energy in Hungarian conditions and three times as much in Madrid as the house itself spends,” the Odooproject team states. “This amount is able to serve two other house’s needs, or provide a 70-kilometer (43.5-mile) long travel distance – daily – for an electric car.”

Builders aim for super-energy-efficient homes

Builders aim for super-energy-efficient homes | Sustain Our Earth | Scoop.it

Crowned with three gables and painted in hues of gray and white, the suburban home in Lake Forest doesn't look much like the domicile of the future.

But as summer heat radiates off the fresh asphalt outside, the home runs comfortably at full tilt indoors. Recessed lights shine, radios blare and air-conditioned splendor greets hot skin. Despite all systems going, the property is producing more electricity than it can consume on a warm summer day — and that's the goal.
