Renew

This Boulder, Colorado remodel by fuentesdesign demonstrates the possibility of renewal in American suburbs, and Passive House design principles. Once an inefficient single story 1,000 square-foot ranch house with a forced air furnace, has been transformed into a two-story, solar powered 2500 square-foot three bedroom home ready for the next generation.

During the coldest part of the Colorado winter, a wood stove for ambiance and low carbon back up heat creates a special place in both the living and kitchen area, and upstairs loft. This ultra energy efficient home relies on extremely high levels of insulation, air-tight detailing and construction, and the implementation of high performance, custom made European windows and doors by Zola Windows. Zola’s ThermoPlus Clad line, which boasts R-11 triple glazing and is thermally broken with a layer of patented German Purenit®, was selected for the project.

With air-tight construction, this home meets the Passive House Retrofit (EnerPHit) air-tightness standard of
