As an exercise in green design, this LEED Platinum–certified house puts a check in every column: passive solar, active solar, rainwater collection, natural daylighting and ventilation, energy-efficient electrical and mechanical systems, resource-conserving materials, a tight building envelope, low-VOC finishes, and no-irrigation landscaping. What got the attention of our judges, though, was that its environmental ethos also yields a thoroughly pleasing aesthetic experience.
