ENVOLVENTES ARQUITECTONICAS ENAR SL

Their core work

ENAR is a Spanish SME whose name says exactly what they do: "Architectural Envelopes" — the external skin of buildings (facades, walls, roofs). Their practical expertise covers sustainable building envelope design and renovation, integrating renewable energy elements such as solar collectors and photovoltaic panels directly into building structures. They also work with digital building management systems (BEMS) and digital twin models to track and optimize energy performance. In EU projects, they contribute as a focused technical partner — bringing applied envelope construction knowledge within large multi-partner consortia tackling building renovation and sustainable construction challenges.

What they specialise in

How they've shifted over time

In their first H2020 project (starting 2019), ENAR worked on bio-based and circular construction — wood systems, rural development linkages, and environmental assessment of construction materials. By 2021, the focus shifted decisively toward the energy performance and digital management of building envelopes: zero energy buildings, solar integration, BEMS, and digital twins. The trajectory is a clear move from sustainable materials and rural construction toward smart building renovation and energy digitalization.

ENAR is heading toward smart building renovation — combining physical envelope retrofitting with digital monitoring and energy optimization — which positions them well for the EU Renovation Wave agenda and future calls targeting deep building decarbonization.

How they like to work

ENAR has participated exclusively as a consortium partner — never as project coordinator. With 56 unique partners across just two projects, they operate inside large, diverse international consortia averaging roughly 28 partners each. This pattern suggests they are a well-defined specialist contributor: they bring a focused technical piece (envelope design and construction expertise) to broader programs, rather than driving the overall research agenda.

ENAR has built a wide network of 56 unique partners across 18 countries through just two projects, reflecting the large multi-national consortia typical of Horizon 2020 Innovation Actions. Their partners likely span research institutes, construction companies, municipalities, and technology providers across Europe.

What sets them apart

ENAR occupies a precise niche: the building envelope, where energy performance, materials innovation, and digital integration all meet. Unlike general construction firms, they focus on the external building skin as a functional system — not just a structural element. Their dual track across bio-based rural construction (BASAJAUN) and high-tech digital renovation (ENSNARE) shows they can bridge low-tech sustainable materials with smart building management, which is rare for an SME of this size.

Highlights from their portfolio

• ENSNARE
  Directly aligned with ENAR's core identity — envelope systems — and their largest funded project (EUR 277,863), targeting the EU's key renovation challenge: retrofitting building envelopes with integrated solar generation and digital energy controls.
• BASAJAUN
  An unusual cross-sector project connecting rural timber supply chains with urban construction demand via circular models, demonstrating ENAR's reach beyond pure energy retrofitting into systemic construction innovation.
