Karuna House, a single family residence which stands on the hilltops of Yamhill County, Oregon has received the Passive House (PHUIS+), Minergie-P-ECO and LEED for Homes Platinum certifications. It is the only house in the world to receive all these hallmark certifications of green building. The house was designed by Holst Architecture and built by the company Hammer & Hand.
Last week, the Zero Net Energy (ZNE) house was unveiled in Clovis, California. The three-bedroom, two-bathroom home has a living area of 2,064 square-feet and was built as a join effort between BIRAenergy Consulting and De Young Properties. Pacific Gas and Electric (PG&E) offered technical assistance to the builders in trying to find ways of getting the home to use only one-third of the energy needed for a house built to minimum code. ZNE House was built to become a model for future net zero homes in the area.
The house features numerous energy-efficiency improvements, which are in accordance with California’s Long-Term Energy Efficiency Strategic Plan. This plan stipulates that all new residential construction in California will be net-zero by the year 2020. The house will not be made available for purchase yet, as it will serve as a prototype to study how well it functions and what improvements have yet to be made.
Last week the judges of the 2013 Solar Decathlon announced this year’s winner. The award went to Team Austria’s LISI House, which was a clear leader all along, having already won the Communications, Market Appeal and Energy Balance competitions. With LISI house, Team Austria sought to create a home, which seamlessly combines indoor and outdoor living, and can be built anywhere, be it in the Alpine forests of Austria or the temperate regions of California.
Team Middlebury is one of the twenty teams chosen to compete in this year’s US Department of Energy Solar Decathlon competition and their entry is the design and building of a socially and environmentally sustainable house called the InSite house. The team is made up of more than 100 Middlebury College undergraduate students from over 25 different academic disciplines. The finished two bedroom and one bathroom house will measure 956 square feet, while the building costs are $250,000.
The first team from the Czech Republic to enter the Solar Decathlon is Team CTU, made up of 26 students who set their sights on designing and building a prototype for future housing while raising awareness of solar energy, energy efficiency, and Czech architecture and engineering.
Their submission in the Solar Decathlon 2013, for which judging takes place in October 2013 in Irvine, California, is AIR House, which stands for Affordable – Innovative – Recyclable. Utilizing energy effective materials and technologies, AIR House provides a comfortable environment for older generations that appeals to the senses and respects the environment.
Recognizing a housing crisis in New England, where many renters and homeowners pay over a third of their income on housing, much of which includes homes that were built before 1950 and are extremely inefficient, the ∆T90 team at Norwich University in Vermont designed a high performance, affordable solution that has been accepted in the Solar Decathlon 2013 that takes place in October 2013 in Irvine, California.
Addressing concerns that include inefficient heating systems, insufficient insulation, and leaky construction of door and window assemblies that contribute to fuel costs that are sometimes equivalent to mortgage payments, the ∆T90 team took “an unapologetic design position” to deliver a modular home that is tailored to the northeastern region of the United States.
