In addition to "monprojetrenov", an innovative retrofitting scheme for individual houses has been developed. It includes the insulation of attics, walls and the installations of smart thermostats in combination with hybrid solar systems. The geographic scope of this action comprises Ile de Nantes and its southern neighbourhoods. This scheme demonstrates the feasibility of introducing new technologies such as intelligent thermostats combined with solar hybrid systems in single-family homes. As part of the scheme, ten individual houses are being retrofitted and tested for further replication.
