Ray Armstrong’s mountain home in Colorado Springs is a sprawling 5,500 square foot structure, with the living space extending outdoors where the owner’s fish ponds and water gardens are located. Armstrong is an award-winning koi fish enthusiast, and his home uses even more energy since the ponds and tanks, where his fish are, require precise temperature and water regulation. Since such a large home also consumes vast amounts of energy, Armstrong enlisted the help of David Bednarski, owner of Bestway Mechanical in Colorado Springs, to help him install the necessary solar and other technologies to reduce this footprint.
Solar ovens are a great way to cook sustainably, but they have the drawback of not working very well on cloudy days. However, the new SunFocus solar hybrid oven, made by Sun BD Corporation, takes care of that problem. And what’s more, you can even use this oven to cook at night. This is possible because the SunFocus oven has a hybrid solar and electric system, with the latter taking over once the sun sets or hides behind the clouds.
Harold Turner’s home near Concord, New Hampshire measures 3,370 square feet and was built using the ROSE construction method, which was created to build affordable net zero energy and cost effective homes in a wide variety of geographical locations and environments. R stands for “Renewable energy production,” O and S stand for “Owner driven spatial design,” and E is for “Energy efficient construction,” while the entire house is known as ROSE cottage and serves as a prototype and test bed for future homes to be built using this method. The entire home was built for $175 per square foot.
