Cost-Effective Energy Efficient Methods for Refurbishment and Retrofitting of Buildings: Materials, Technologies, Optimization, and Case Studies provides up-to-date knowledge on this important research field. Divided over three key parts, the book's chapters cover materials and innovative technologies, optimization strategies, and actual case study applications that highlight the impact of different climatic conditions, social factors, and the economic specifications of each retrofit process. Emphasis is placed on cost efficiency, which is key in any energy retrofit process. Taking into consideration key changes in the Energy Performance of Buildings Directive-EPBD and the European Union Green Deal on Refurbishment and Renovation, this book will be a valuable reference resource for materials scientists, architects, civil engineers, and all those working on cost-effective and energy efficient retrofitting and building refurbishment.
