If you want an inexpensive, environmentally sound source of energy for your home, you need look no further than the sun. Solar heat is not subject to rate increases, is totally renewable, pollution free and requires little or no technology. It is here for you today, and can easily provide up to 50% of your space and water heating requirements. This is a book that simply and clearly explains the principles of using solar energy to heat your home. Anyone building a new home, or renovating an old one can incorporate one or several aspects of solar energy into their design. Taking you through the process of designing a solar home from the ground up this manual is also a basic course in conservation and sustainable house design. If you live in a 'heating' climate, meaning if you have space heating requirements for most of the year then this is an invaluable resource. A house is the biggest single investment most of us will make in our lives - the way it is built and how it operates can reflect a long term investment in both the building and the planet.

The use of solar collectors for domestic hot water over the past 20 years has demonstrated that solar heating systems are now founded on a reliable and mature technology. However, the development of similar, but more complex, systems to provide both domestic hot water and space heating (solar combisystems) resulted in a diverse range of different designs that were not carefully optimized to reflect local climate and practice. Application of energy-efficient building strategies such as improved thermal insulation and use of low temperature heat supply systems is becoming increasingly common. This trend, combined with growing environmental awareness and the subsidies available in certain countries, favours an increase in market share for solar combisystems. The need for guidelines in selecting the appropriate system and designing this system according to the specific needs of the building and the local environment is therefore now increasingly pressing. This book fills that need.

This manual was prepared primarily for use in conducting a practical training course on the design of solar heating and cooling systems for residential and small office buildings, but may also be useful as a general reference text. Only active solar systems are described in this manual. Other books are available for passive designs. Liquid and air-heating solar systems for combined space and service water heating or service water heating only are included in this manual. Furthermore, only systems with proven experience are discussed to any extent. This manual was developed by the staff of the Solar Energy Applications Laboratory and vocational education specialists at Colorado State University in cooperation with the NAHB Research Foundation. A national advisory committee selected from various sectors of the home-building industry, university sources, private practice, and government, was established to provide advice and general guidance.
