The new Energy Saving Ordinance (EnEV) imposes high demands on roofers and carpenters. The 4th revised edition of the title "Thermal and Moisture Protection in Roof and Timber Construction" supports you in planning and executing energetically safe constructions. How can the new Energy Saving Ordinance (EnEV) be best implemented in practice? How can legal issues be avoided? What financial savings can be achieved through thermal insulation? What funding is available? This specialized book answers these questions in an easily understandable and practical manner using current project examples. In addition to the building physics fundamentals of thermal and moisture protection, it addresses the practical impacts of thermal bridges and air leaks, as well as component-related calculations such as U-values or condensation risk assessments. The application of the current Energy Saving Ordinance is explained using specific construction projects.
