What is Building Retrofitting

Green retrofitting and housing energy efficiency are some of the most debated topics nowadays. They contribute to lower costs for the involved households and more efficient sources of energies, which lead to a cleaner environment. The number of methods and devices for increasing the energy efficiency of housing ranges from very simple methods to complex ones. In spite of the fact that in the research there is high interest for the development of energy-efficient housing systems, it is also important to inform the consumer about the existence of such devices and to convince them to use these types of systems more frequently. The objective of the chapter is to give an overview of the popularity and the interest of the consumers towards different forms of housing energy efficiency systems and green retrofitting methods.
