Chapter Energy:

Energy supply appears to be one of the major problems because it has a considerable impact on the climate and there are worries about future energy shortage that can result in political instability. Is finding a solution to the energy problem the solution of all environmental troubles? In the 60s, the energy demand was calculated by linear equation that results in immense energy demand and expensive atomic energy programmes with well-known problems such as cost, risks, uranium resources and rods. Even today, there are inconsistent extrapolations regarding energy costs and resources. Securing the power supply only via renewable energies seems to be far from the reality at hand. Cost calculations are not always realistic. Even the degree of impact on the world climate could be scrutinised.
The chapter “Energy” describes the topics state of affairs with its influence on the building sector as a basis for guiding objectives. Today, problems concerning civil engineering could, to a large extent, be solved by expert knowledge. There are a variety of possible solutions and useful procedures when making initial calculations. The chapter demonstrates how to develop energy concepts and how to plan high-quality low-energy houses.
