Most houses being built today are not as energy efficient as they could be. Every builder, if asked, "Do you build energy efficient houses?" will persuasively answer, "Yes." Without studying energy efficient housing in an objective way, most homebuyers will believe the builder's answer. Yet studies and tests prove otherwise. After reading the eighteen clearly defined principles in this book, the reader will have a basis for understanding and comparing the efficiency of one house to another and one builder to another. The eighteen easy-to-implement principles are based on tried and proven solutions for conservation and clean renewable energy generation. Homes that are built to be "holistically green" are economical and maintain their value. And by saving energy and improving indoor quality, they are environmentally responsible and provide a healthier place to live. Building an energy-conscious home is smart--a smart financial investment, a smart approach to our energy and environmental challenges, and "the right thing to do." The benefits of planning for and building based on the Eighteen Principles in total are greater than the sum of the individual principles. References are made in the text--from principle to principle--that will be helpful in understanding how each one is dependent in some way on the other. Economic and financial considerations are discussed based on examples and case studies. The studies show that, while it does cost more to build a house that is energy efficient, environmentally friendly and responsible, structurally stronger, and resistant to the challenges of time, a well designed, efficient home can be more economical to live in--beginning with the first month that utility bills are received. And it is a better investment because of the higher resale value and reduced maintenance. This book will educate and instill confidence in consumers with regard to their largest personal investment: their home. They will understand what specifics to look for to get an energy efficient, healthy home that will save them money and have a positive impact on energy conservation, energy generation, and climate change.
