Innovative technologies. Experiences from new buildings

The move towards Nearly Zero-Energy Buildings (NZEB) in the Member States has allowed for innovative technologies to be steadily introduced into the building markets over the last few years. The purpose of this factsheet is to collect and present initial experiences with new technologies in the Member States. Information has also been gathered on how Member States incorporate these technologies into their national Energy Performance (EP) calculation methods. The innovative technologies discussed in this context are demand-controlled ventilation, home-automation systems, reversible heat pumps (for cooling in summer), and advanced solar-shading systems. Considering all four technologies, system variations, how commonly they are used, and in which types of buildings, differ widely among the participating countries. Also, the system's impact on the building energy use is calculated differently from country to country and from technology to technology. An exchange of viewpoints between countries, as well as with the ""European Committee for Standardization"" (CEN), is expected to contribute to the broader use of innovative technologies.
