Modern Dream Home is Energy-Positive

May 21, 2015 | Climate Zone 4C, Seattle, Washington

A Seattle couple spent two years searching for their dream home before deciding to build a new custom home. They turned to zero-energy-home builder Ted Clifton, Jr., who built them a modern two-story house with a mother-in-law suite and views of Lake Washington from the rooftop deck.

Clifton, the owner of of TC Legend Homes, calls the home a “positive energy home” — one that produces more energy than the home itself consumes. In fact, the home should produce enough electricity to power an electric car with the charging station set up in the garage.

New California Home Meets the Passivhaus Standard

Apr 27, 2015 | Climate Zone 4, San Jose, California

This energy-efficient house in San Jose, California, not only produces enough solar electricity to meet its annual energy needs, it also complies with the stringent PassivhausA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. Developed in the early 1990s by Bo Adamson and Wolfgang Feist, the standard is now promoted by the Passivhaus Institut in Darmstadt, Germany. To meet the standard, a home must have an infiltration rate no greater than 0.60 AC/H @ 50 pascals, a maximum annual heating energy use of 15 kWh per square meter (4,755 Btu per square foot), a maximum annual cooling energy use of 15 kWh per square meter (1.39 kWh per square foot), and maximum source energy use for all purposes of 120 kWh per square meter (11.1 kWh per square foot). The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.14. The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates. standard.

High-End Green in the Hamptons

Dec 9, 2014 | Climate Zone 4, Sagaponack, New York

By Richard Stott

The Hamptons are flush with poorly built, energy hog spec homes on an acre or two. Many of these homes have huge lawns, pools, tennis courts, and koi ponds. Most are thankfully hidden by tall privet hedges. Of course, the Hamptons are also known for some of the most extravagant and well-built residences in the world. All of these estates, well-built or not, require an army of maintenance workers to keep them tidy and presentable.

A Passive Solar Home from the 1980s

Feb 25, 2014 | Boulder, Colorado

Back in the early 1980s, I built a 1,480-square-foot passive solar home in Boulder, Colorado. There have been substantial improvements in active solar equipment since then. But today’s passive solar design principles are quite similar to the principles preached in the early 1980s. Solar energy provides almost all the winter heating and hot water for this home. The cost savings I achieved by eliminating a central heating system were invested in thermal massHeavy, high-heat-capacity material that can absorb and store a significant amount of heat; used in passive solar heating to keep the house warm at night. , additional insulation, and better glazingWhen referring to windows or doors, the transparent or translucent layer that transmits light. High-performance glazing may include multiple layers of glass or plastic, low-e coatings, and low-conductivity gas fill., so no additional construction costs were incurred compared to conventional construction.
