Klopf Architecture studio have designed the Net Zero Energy Modern House located in Cupertino, California.
Built in a cul-de-sac lot, this lovely Eichler-inspired residence was completed in 2011.
Description by Klopf Architecture:
The owners both work from home, and wanted this to be their “final” residence, so we needed a larger-than-normal home to suit their lifestyle needs. Instead of adding a second story on top (which would’ve annoyed the neighbors) they opted for a partially-submerged lower level, which we designed to seem as little like a basement as possible (with a pulled-back floor plate, a light-filled “atrium” and a lower level light well).
To preserve privacy, bring in light while minimizing unwanted solar heat gain, and provide connection to nature, we oriented a large window wall north to the back yard, sloping the ceiling of the great room up to increase the light and connection to nature in that space. The sloping roof also provides a surface suitable for mounting the 13.4 kW PV system. Other building faces have smaller, punched windows that maximize privacy.
The owners were very concerned about the environment, specifically about energy and resource efficiency. They directed us to use materials that would last as long as possible while avoiding “food for termites” and designing a high-performance sustainable home. So in conjunction with our Mechanical Engineer we designed a net-zero energy home featuring insulated concrete forms (ICFs), structural insulated panels (SIPs), high-performance windows, cementitious siding, and an 13.4 kW solar Photovoltaic (PV) system sized to cover all the energy use in the house. No natural gas will be used in the home, with the possible exception of a backyard BBQ.
