PROJECT ZERO A/S

Their core work

Project Zero A/S is a Danish climate initiative company based in Sønderborg that drives the energy transition in the built environment — specifically in housing, neighborhoods, and municipal energy planning. They specialize in mobilizing housing associations and tenants to invest in energy renovation, designing financing models for building upgrades, and orchestrating citizen engagement around zero-emission goals. Their practical focus is on turning climate ambitions into concrete investment decisions at the community and housing-district level.

What they specialise in

How they've shifted over time

In 2015-2018, Project Zero focused on building renovation market development (REFURB) and smart city decarbonization (SmartEnCity) — essentially the technical and urban-planning side of energy efficiency. From 2018 onward, their focus shifted decisively toward the human and financial dimensions: tenant engagement, housing association decision-making, social acceptance, and innovative financing (HAPPI, MISTRAL, ARV). Their most recent work integrates circular economy thinking and community-scale climate action, moving beyond individual buildings to whole neighborhoods.

Project Zero is moving from technical energy efficiency toward integrated community-scale climate solutions that combine circular economy, citizen participation, and green financing — a valuable trajectory for anyone building district-level decarbonization projects.

How they like to work

Project Zero mostly participates as a partner rather than leading consortia, having coordinated only one project (HAPPI) out of five. However, their network is remarkably broad for an SME — 117 unique partners across 16 countries — suggesting they are a trusted contributor who gets invited into large demonstration and innovation consortia. They bring practical, on-the-ground implementation capacity from Sønderborg rather than research infrastructure, making them a strong local deployment partner.

With 117 consortium partners across 16 countries, Project Zero has built a wide European network despite being a small Danish SME. Their connections span smart city consortia (SmartEnCity) and climate-positive community projects (ARV), giving them links to municipalities, housing organizations, and energy agencies across Northern and Western Europe.

What sets them apart

Project Zero sits at the rare intersection of housing-sector expertise and climate action — they understand both the technical side of building energy renovation and the social dynamics of convincing tenants and housing boards to invest. Most energy SMEs focus on technology; Project Zero focuses on the decision-making process that gets technology adopted. For any consortium needing a partner who can demonstrate real-world deployment in a living community (Sønderborg's 3,440+ homes), they offer proven engagement methods and financing models.

Highlights from their portfolio

• SmartEnCity
  Largest project by far (EUR 1.4M to Project Zero), a flagship Smart Zero CO2 Cities demonstration across Europe with a 6-year timeline.
• HAPPI
  Their only coordinated project, directly reflecting their core mission: energy efficiency investment planning for housing associations managing 3,440 homes.
• ARV
  Most recent and forward-looking project (2022-2026), combining circular economy, zero-emission neighbourhoods, and green digital financing — signals their strategic direction.
