The book focuses on no-cost and low cost projects for buildings of any type. The projects are arranged within each chapter in order of increasing complexity. The first ones begin with projects that, say will apply to any building (including residences), then they get increasingly complex. So there are projects for any budget and any type of facility. In fact, the emphasis is on those that can be done as part of regular maintenance!

The intended audience is not strictly engineering design professionals as you might expect from the title, but also architects, designers, facility managers, realtors, and small business owners.

Finally, there is a form in the book by which you can request some software (available free from my web site) to evaluate the projects featured in the book. Energy analysis of buildings is a complicated business and it is very educational to have a simple computer routine to study an actual building. The software compliments the projects nicely, allowing many potential projects to be evaluated easily. For example, changing roof color or window shading or operating hours.
