This is the good practice's implementation level. It can be national, regional or local.
About this good practice
The area where this action has taken place (called “El Rancho”) is considered vulnerable, which causes many households to be in a situation of energy poverty.
The Andalusian Regional Government, through its Housing and Rehabilitation Agency (AVRA), carries out rehabilitation interventions in areas of this type, especially in social housing. Within these rehabilitations, energy improvements play a relevant role, including renewable energy. Specifically, in this good practice, equipment has been installed to produce sanitary hot water using solar energy, which supplies 149 social houses (besides other energy efficiency actions). In addition, this solar equipment includes an on-line, real-time monitoring system that allows to know the operation of the system at all times, allowing to analyse the consumption and performance of the solar energy installations.
The beneficiaries of this good practice are the users of social housing.
Throughout the process of preparation and execution of the works, permanent contact was maintained with the neighbours, informing them about the works and managing the incidents that occurred with very satisfactory results. For this, several meetings were held with the neighbours and all the particular queries that arose were attended to.

Resources needed
The investment made in this action amounts to 1,440,507€ (80% ERDF Funds) and the employment generated is estimated at 72 jobs.
Evidence of success
The energy rating of the homes has improved from E to D.
Neighbours perceive that the thermal comfort of their homes has improved, and they save approximately one butane cylinder a month and still have more hot water for other uses (such as cleaning the home).
Finalist in the Official College of Architects of Seville awards in 2019, disseminated in international conferences and visited by a group of Chilean government technicians interested in learning about good practices in the energy field.

Potential for learning or transfer
The intervention includes a specific test plan to control energy measures, before, during and after the works, measuring the air tightness parameters of the houses. In addition, the solar thermal energy production facility has an on-line, real-time monitoring system that allows to know the operation of the system at all times, allowing to analyse the consumption and performance of the installation in each building.
The set of these data will be very useful for the analysis of the operation of this type of facilities with a view to the future application of these systems in other interventions and for the transfer of knowledge to other entities and regions.
