In The New Net Zero, sustainable architect Bill Maclay charts the path for designers and builders interested in exploring green designís new frontier net-zero-energy structures that produce as much energy as they consume and are carbon neutral. Geared toward professionals exploring net-zero design, the book will enlighten nonprofessionals seeking time-tested ideas and strategies.
