SOCIEDAD MUNICIPAL ZARAGOZA VIVIENDA SL

Their core work

Zaragoza Vivienda is the municipal housing company of Zaragoza, Spain, responsible for managing public and social housing stock on behalf of the city. In EU research projects, they function as an end-user and real-world pilot site — their managed buildings serve as living laboratories for testing energy efficiency interventions. They contribute operational knowledge of building portfolios, tenant relationships, and municipal procurement processes that academic or technology partners cannot replicate. Their value to research consortia is grounded access to actual occupied buildings and the institutional mandate to implement energy upgrades at scale.

What they specialise in

How they've shifted over time

Their first project (TRIBE, 2015–2018) focused on the human side of energy efficiency — changing occupant behaviour in public buildings through digital tools and gamification. Their second project (BuildHEAT, 2015–2020) shifted sharply toward the technical side: deep retrofits involving heat pumps, active façades, and district-scale thermal systems. This suggests the organisation moved from soft interventions toward hard infrastructure upgrades, possibly reflecting lessons that behaviour change alone is insufficient without technical system overhauls. Both tracks remain relevant, and the combination — buildings they manage, tenants they can engage, and systems they can retrofit — makes them a distinctive end-user partner.

Zaragoza Vivienda is moving toward deep technical decarbonisation of their housing stock — future collaborations around district heating, heat pump deployment, or large-scale façade renovation would be a natural fit.

How they like to work

Zaragoza Vivienda has participated in both their H2020 projects as a consortium partner, never as coordinator — consistent with an end-user organisation that provides access and operational context rather than scientific leadership. With 26 unique partners across 9 countries spread over just 2 projects, they work in large, diverse consortia. This signals they are comfortable operating within complex multi-partner structures and contribute a clearly defined role: building access, municipal authority, and on-the-ground implementation capacity.

They have built connections with 26 partners across 9 countries through only 2 projects, indicating engagement in large international consortia. Their network spans Southern and Central Europe, typical of building energy projects coordinated by Spanish or German research institutions.

What sets them apart

Most building energy research lacks credible end-users with real managed housing portfolios — Zaragoza Vivienda fills that gap as a public authority with direct control over residential and public buildings in a mid-sized Spanish city. For any consortium that needs a municipal housing operator to validate, pilot, or demonstrate solutions in occupied social housing, they offer both the buildings and the institutional legitimacy. Their dual exposure to behavioural and technical energy interventions makes them more rounded than a pure pilot-site partner.

Highlights from their portfolio

• BuildHEAT
  The largest of their two projects (EUR 483,175 EC funding, 5-year duration) tackled full systemic building retrofit including heat pumps, active façades, and district-level thermal control — representing their deepest technical engagement.
• TRIBE
  An unusual combination of serious games and ICT tools applied to energy behaviour in public buildings, showing their willingness to test unconventional human-centred approaches in real municipal settings.
