Energy-Efficient Retrofit of Buildings by Interior Insulation offers readers worldwide a comprehensive coverage of the current research and practice in German Language Countries. The editors have invited specialists both in academia and industry to present their expert view on Materials, Methods and Tools to improve thermal comfort and health conditions in the indoor environment.

In the first chapter the editors provide an overview of the development of energy efficiency for building retrofit in German Speaking Countries and the role of internal insulation. The first part of the book covers materials with chapters on Brick, Wood, Plaster, Clay, and Natural Stone. The chapters explain the impact of internal insulation in those materials and how to cope with problems such as moisture build, mold and algae growth. Part two covers the construction procedures. The chapters provide practical advice on how to apply internal insulation in the most effective way, including Salt Efflorescence, Noise Protection, Fire Prevention, Water Uptake Measurement, and Plinth Waterproofing. The final part is devoted to the tools, including Energy Analysis, Health monitoring, Indoor Climate measurement, and Cost Analysis.

The practical approach of the book, with examples in all chapters, makes Energy-Efficient Retrofit of Buildings by Interior Insulation valuable for Civil and Architectural Engineers involved with building retrofit. The book may also be useful to researchers in the field of Building Physics due to the breadth of the coverage.
