Solar Heating

Our innovative use of earth tubes and heat recovery devices reduce energy for heating and cooling by 20% to 60%. While we have been involved with several Net-zero projects, we prefer the simple and economical projects that are easy to maintain. Our first solar heating project was constructed in 1975 and since then we have learned what is efficient and practical. We have innovative designs that significantly reduce the cost of solar heating by simply using a metal roof that also functions as a solar collector. Unlike other designers, many of our projects include provisions for monitoring to provide data that substantiate our performance claims.
