Zero Energy Casita

// 1,051 sf

Project Overview

The Zero Energy Casita is an example of a balancing act. It tells the story of a family looking to lessen their second home’s carrying cost and energy dependence, while creating a healthy, efficient environment in which to raise their small family.

The home is designed and situated on the lot to frame the view of a nearby lake while integrating naturally into the site through its rustic design and variety of reclaimed materials. The native trees surrounding the house provide shade and protection from the hot summer sun, while the 100' bluff on top of which the house sits provides a great location for the wind-powered generator that produces 100% of the home’s electricity.

This home is Builders Challenge Certified and NGBS Certified to the Emerald Level.
