In Turin, Italy, when such an assessment was undertaken it came to light that one building segment, multifamily, high-rise buildings constructed before 1980 accounted for more than 70% of total residential floor area and about 70% of total energy consumption for heating (IEA, 2016a). This information allowed for better targeted energy saving measures. Also, In Paris, an energy information advisor has been providing support to building pennit applicants for energy saving projects since 2008 covering issues on sustainable building renovation (Maine de Paris, 2012).
