The New Net Zero

Leading-Edge Design and Construction of Homes and Buildings for a Renewable Energy Future

The new threshold for green building is not just low energy, it’s net-zero energy. In The New Net Zero, sustainable architect Bill Maclay charts the path for designers and builders interested in exploring green design’s new frontier net-zero-energy structures that produce as much energy as they consume and are carbon neutral.

 In a nation where traditional buildings use roughly 40 percent of the total fossil energy, the interest in net-zero building is growing enormously–among both designers interested in addressing climate change and consumers interested in energy efficiency and long-term savings. Maclay, an award-winning net-zero designer whose buildings have achieved high-performance goals at affordable costs, makes the case for a net-zero future; explains net-zero building metrics, integrated design practices, and renewable energy options; and shares his lessons learned on net-zero teambuilding.

Designers and builders will find a wealth of state-of-the-art information on such considerations as air, water, and vapor barriers; embodied energy; residential and commercial net-zero standards; monitoring and commissioning; insulation options; costs; and more.

The comprehensive overview is accompanied by several case studies, which include institutional buildings, commercial projects, and residences.  Both new-building and renovation projects are covered in detail. 

The New Net Zero is geared toward professionals exploring net-zero design, but also suitable for nonprofessionals seeking ideas and strategies on net-zero options that are beautiful and renewably powered.


"Design is the first signal of human intention. Thoreau once wrote, 'What's the use of a fine house if you haven't got a tolerable planet to put it on?” Bill Maclay thoroughly describes an intentional architect’s Platonic search for truth in beauty and Aristotelian search for truth in science with a Hippocratic oath to seek to 'do no harm.'  With this fine book he provides a robust foundation for buildings that can rise up to become beneficial to people, place and planet."--William McDonough, coauthor of Cradle to Cradle and The Upcycle, founder of Cradle to Cradle Products Innovation Institute

“This book will become a game changer at a pivotal point in history. The New Net Zero is a technical manifesto that brings together engineering, ecology, architecture, energy, the construction industry, transportation, and design into a coherent whole. Its goal is to transform the built environment into landscapes that heal, while reversing climate change. Immensely practical, thorough, and technologically comprehensive: it is a masterful job.”--John Todd, founder, John Todd Ecological Designs

"The New Net Zero is a thorough philosophical and technical rendering of the subject. What makes it exciting and meaningful is that it is not just about the details and technology, it also demonstrates how it is essential to build on human and other natural-system relationships to succeed. There is hope in these pages; this book goes a long way to prove that a sustainable future is possible and practical."--Bill Reed, coauthor of The Integrative Design Guide to Green Building and president of the Integrative Design Collaborative

"The New Net Zero is a treasure trove of design and construction knowledge gleaned over a 40-year career in creating leading-edge, net-zero-energy and near-net-zero-energy buildings of all types and sizes. Detailed, practical information on design is interspersed with beautifully illustrated case studies of Maclay's projects. If I could recommend only one book on low-energy, green building today, this would be it."--Alex Wilson, founder of BuildingGreen, Inc. and president of the Resilient Design Institute 

"The New Net Zero is comprehensive, authoritative, beautifully written, well illustrated, and incredibly timely. With the effects of climate change escalating rapidly, moving away from fossil-fuel energy has become desperately necessary. The good news is that it has now become possible to cost effectively power our buildings entirely with renewable energy sources, and this is the best book yet about why and how to build net-zero buildings. Maclay and his team have long been leaders in proving the net-zero proposition, and he has gracefully delivered a detailed manual for the big design and building breakthrough that can happen now."--Tedd Benson, founder of Bensonwood & Unity Homes and author of Building the Timber Frame House, The Timber-Frame Home, and Timberframe
