Residential Energy Efficiency Credit Line

Eligibility criteria for windows to be financed under the REECL Programme

Definition:

Energy efficient windows comprise of:

•
glazing: factory made sealed units, consisting of two or more panes, separated all round by a spacer, with a gap between the panes filled with air or argon;
•
frame: made from wood, PVC or aluminium.

Eligibility Criteria:

Maximum U-value for the whole window: <2 W/m²K as per EN ISO 10077-1 and Bulgarian Building Codes

If a certified U-value for the whole window is not available, the minimum set of criteria laid out in the table below applies.
