John began his energy career in the late 1970s conducting hands-on workshops building solar greenhouses and solar collectors for the Alternative Energy Research Organization (AERO) and the National Center for Appropriate Technology (NCAT). While working at NCAT, he learned the publishing business, working as a writer, art director, and project manager on around 15 publications. He founded Target Energy Savers in 1981, a small energy service company, providing diverse energy-conservation services for residential and light commercial buildings. He sold Target in 1988, and the company still operates successfully in Helena, Montana.
In 1987, John founded Saturn Resource Management and began publishing books on energy conservation and energy efficiency for buildings. Since then, he has authored or co-authored dozens of energy publications. The best known on these are Residential Energy: Cost Savings and Comfort for Existing Buildings, Your Mobile Home: Energy and Repair Guide for Manufactured Housing, and Saturn’s popular weatherization field guides, which are used by approximately 32 state weatherization programs.
John recently spent three years in the Czech Republic, where he investigated European construction and retrofit techniques. His research included hydronic heating efficiency, insulation methods, air sealing techniques, and moisture control for multifamily masonry buildings.
John has extensive experience researching and developing energy-related publications for technicians, government officials, industry representatives, and the general public. He is the author or co-author of 8 books and approximately 40 shorter publications on energy efficiency. He is also a technical illustrator, photographer, and desktop publisher. Some publication titles appear below.

John Krigger is a nationally recognized expert in the field of energy conservation for buildings. He combines lifelong experience in energy-conservation technology with the ability to communicate effectively. For more than 20 years, he has produced publications, developed curriculum, and presented seminars and on energy efficiency. John is co-developer of the Comprehensive Home Energy Curriculum (CHEC), which is now Saturn Online. John Krigger and Chris Dorsi have also created hours of video training for Saturn Online.
Currently, John instructs energy raters and analysts at Saturn Online through videos, narrated slide shows and written communication on electronic forums. From 1979 to 2007, John trained technicians in the Weatherization Assistance Program, Home Performance with Energy Star, and the utility energy conservation programs of 25 states to perform energy audits, insulate, service heating systems, reduce cooling costs, and seal air leaks in homes.
John has served as a consultant to the U.S. Department of Energy, over 30 State government agencies, Pacific Gas and Electric, National Renewable Energy Lab, Oak Ridge National Lab, the National Rural Electric Cooperative Association, Energy Ideas Clearinghouse, E-Source, KEMA Consulting, Conservation Services Group, the Northwest Regional Technical Forum, RESNET, the Building Performance Institute, and the Electric Power Research Institute.
The following is a selection of real-life experience from John’s long career in energy efficiency.
