Wisconsin Home Powered by Solar, Wind and Geothermal

This home on 40 acres in Wisconsin is designed to provide power and water off the grid for its needs. The design incorporates sustainable principles, including solar hot water, a wind turbine, geothermal heating, passive solar, and natural ventilation. Rainwater runoff is collected into a pond that is integrated into the geothermal system. Sustainable materials throughout the home include concrete floors and countertops that are durable, easy to maintain with non-toxic cleaners and provide thermal mass for utilizing passive design principles.

Poland Embraces CO2 Saver Home

The CO2 Saver House in Lake Laka Poland weathers subzero winter winds and 90-degree summer heat. The home uses a solar water heater above the atrium for hot water that provides 30 to 40 percent in winter and 100 percent in summer. The orientation of the house is specifically designed to expose 80 percent of the structure to light and warmth through the sun’s daily arc. (The total surface area in a conventional building available for solar gain is typically about 65 percent.) The long side of the wedge on the CO2 Saver means there is more surface area to absorb solar energy, plus most of the roof slopes north to south, and all sides of the house have the potential to harvest power.

Floating House Captures Sun for Daylighting

Architect Robert Oshatz is well known for his unique approach to design and architecture. His creations are expressions of identity and form and this house boat comes as no exception. Oshatz wanted to design a house that would only function if it were situated on water, not something that could work equally well on land. The actual construction of the home had to occur offsite, on the connected Columbia River, then pulled by barge to its mooring. Also, moorings on either side were less than 10 feet away, so the house had to provide privacy despite the close proximity to neighbors.
