With the energetic renovation of their existing properties, builders can make a significant contribution to climate protection while also reducing heating and operating costs. But which insulation measures are effective? Are building permits required? Are there funding options available? These questions must be answered individually for each building. The authors cover all the necessary fundamentals for renovation planning and provide decision-making aids for selecting appropriate restoration concepts. Step by step, they explain which preliminary investigations are necessary for the structure and which calculation methods are used to assess the energetic condition of individual components. Using real renovation examples, they demonstrate possibilities and pitfalls in implementing different energy concepts in existing buildings. In addition to technical aspects, they consistently focus on the profitability and proportionality of renovation measures. The book is suitable for getting acquainted with the complex topic of energetic renovation. It is aimed at planners, contractors, and interested builders.
