Existing treated floor area (usable floor space): 
559.00 m²
Original situation: 

San Roque Social Housing is a four floors building with 10 apartments and a common area. The thermal envelope has not insulation at all. Ventilation is natural, using opening window sections. Original windows and shutters are made of timber with single glazing, but some owners have replaced them during the years. The poor façade condition, which is made of load bearing bricks, force to the owners to take measures after a compulsory technical inspection.  The roof is built with timber and was improved on 1994.

Modernisation proposal: 


The retrofit works that have been undertaken within EuroPHit include the first step of the refurbishment plan:

Step 1:            Top floor ceiling insulation and airtightness improvement

The next step of the refurbishment plan will be:

Step 2:            ETICS installation

                        New PH windows

                        Airtightness improvement on the outside

                        Mechanical ventilation with HR installation

Step 3:            PV panels


Architects: Albrecht Otxoa-Errarte

Current situation: 

Nowadays, the first step, which includes top ceiling insulation with 160 mm of rock wool over OSB boards as airtightness layer, is being implemented.

Following steps will be implemented when the community get the amount of money that allows them to start the works.

Challenges of the project: 
The main challenge of the project is getting the money that allows them to develop the whole refurbishment works. Neighbourhood association is looking for an alternative funding. The project has been submitted to PAREER CRECE program and other autonomics ones. However, at the moment it is not yet approved.
