The document discusses BUILD UPON, a Horizon 2020 project aimed at helping European countries design and implement strong, long-term national strategies for renovating existing buildings. It will do this by (1) mapping key stakeholders and initiatives in each participating country, (2) creating an online "RenoWiki" tool with information on renovation initiatives in each country, and (3) facilitating workshops to bring together stakeholders to collaborate on developing updated national renovation strategies due in 2017. The project involves 13 countries and aims to lower CO2 emissions, create jobs, and improve existing buildings across Europe.
