Increasing energy efficiency in socially relevant buildings

Plovdiv, Bulgaria’s second-largest city, has evolved from an industrial hub to a centre for business, culture, and history.  With over 18,800 residential buildings, 59% of its energy consumption and 66% of CO2 emissions stem from the residential sector.

The project focuses on the neighbourhood of Trakia which has a strong need for energy renovation due to its outdated infrastructure that exacerbated CO2 emissions. While mainly comprised of private multi-family residential buildings, the area also has kindergartens, schools and other socially relevant facilities.

Plovdiv underscores the need for informed decisions to streamline renovation processes and the need to support city authorities in expanding renovation efforts to more buildings.
