The European Court of Auditors (ECA) has identified weaknesses in the design and monitoring of residential energy renovation measures in Cyprus, Belgium, Italy, and Lithuania that were financed through the Recovery and Resilience Facility (RRF), according to a special report published on Tuesday in Luxembourg. The findings concerning Cyprus cast doubt on the reported energy-saving benefits, as they point to low levels of energy savings achieved through measures that, in practice, do not reduce a building's actual energy consumption.
