Most buildings in Estonia are energy inefficient. The average annual heating energy used in the buildings today is about 200 kWh/m2 compared to the industrial nations with a similar climate which is about 150- 230 kWh/m2. Energy refurbishment loans for citizens, in particular multi-family apartment buildings, are available in Estonia since 2002. In 2009, a KredEx Revolving Fund was set up by KredEx - a financing institution that operates as a private company but is owned and governed by the national government – Ministry of Economic Affairs and Communications. KredEx Revolving Fund provides soft loans for multi- family apartment building owners who wish to reduce energy consumption and increase energy efficiency of their homes. Further financial sources, coming in particular from the EU structural funds (ERDF) and the sale of CO2 emissions allowances are available for the owners in form of grants.
