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.
Architect Virge Temme of Sturgeon Bay, Wisconsin recently received the LEED Platinum for Homes certification for a private residence she designed near Gills Rock. The home was built by Bay Lakes Builders, and the plans were based on the collaboration of all members of the construction and design team so as to ensure proper integration of all systems. The electric and fuel bills for this 2,600-square-foot house were less than $30 per month on average during its first year. This is only the seventh home in Wisconsin to receive the LEED Platinum certification.
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.
