In many existing buildings, energy conservation measures have significantly reduced the demands for heat supply. In new buildings, advances in a wide range of technologies have led to even greater reductions. On the other hand, demands for electrical energy have risen noticeably. Unfortunately, it now seems that the use of both heat and electrical energy is starting to increase, especially in non residential buildings, and without any corresponding increase in the quality of the indoor climate. In this book, the authors present a systematic and holistic approach to both conserving energy and ensuring good indoor climate when designing new buildings or renovating existing ones. In their opinion, the harmonization of the design of a building and its HVAC systems is fundamental to these issues. The authors of Buildings and Energy – a systematic approach wish to share their knowledge and experience in this field with developers, planners and builders. The book is also available in Swedish ISBN 9789154060207.
