Modern design shapes award-winning high performance home
A high performance home that incorporates three of the top green building certifications generates more energy than it uses.
Designed by Holst Architecture and built by Hammer & Hand, the Karuna House exemplifies the role of high design in high performance home building. Perched on a hilltop overlooking the vineyards of Yamhill County, Oregon, the home is the first green building in the world to earn Passive House (PHIUS+), Minergie-P-ECO, and LEED for Homes Platinum certifications.
In January 2015, the National Institute of Building Sciences gave the homebuilder a Beyond GreenTM Merit Award on behalf of the Karuna House and its project team. One of just four Beyond Green Awards granted by the Institute and its Sustainable Building Industry Council this year, Karuna House's award recognizes the home's role as a national exemplar of high performance green building.
The client, a leading proponent of smart climate policy, pursued the project as a case study to compare the world’s most ambitious green building standards.
To achieve the three certifications and meet its net positive energy goals, the Karuna House combines an advanced building enclosure with optimized solar design to drive energy loads to very low levels. Remaining energy needs, including the charging of the client’s electric car, are readily provided by a solar photovoltaic array of less than 10 kilowatts. The project’s laser focus on energy performance (guided by its Passive House and Minergie-P components) is complemented by the broad sustainability and human health goals required by LEED and Minergie-ECO.
The home’s clean modernism and restrained palette help prove that high performance structures can rival the beauty of any building. Karuna House is the recipient of the 2030 Challenge Design Award: Excellence in Residential Net-Zero (AIA Portland, 2013), and the Green Home of the Year Award: Best Building Science (Green Builder magazine, 2014).
