UNION INTERNATIONALE DE LA PROPRIETE IMMOBILIERE

Their core work

UIPI is the International Union of Property Owners, a Brussels-based European association representing the interests of private property owners across EU member states. In H2020 projects, they bring the property owner perspective to building energy renovation initiatives — ensuring that retrofit solutions, financing models, and policy frameworks actually work for the people who own and manage the buildings. Their role is to bridge the gap between technical renovation solutions and the real-world decisions, incentives, and barriers faced by homeowners and landlords across Europe.

What they specialise in

How they've shifted over time

UIPI's early H2020 work (2016–2018) concentrated on the technical side of deep energy retrofitting — nearly zero-energy buildings, envelope improvements, PV integration, and decision-making tools for the existing housing stock (ABRACADABRA, RenoZEB). From 2019 onward, their focus shifted decisively toward the social, financial, and policy dimensions: energy poverty, split incentives in rental markets, one-stop-shop renovation hubs, homeowner engagement, circular renovation, and even blockchain-based energy communities. This evolution mirrors the broader EU policy shift from "how to renovate" to "how to get people to actually renovate."

UIPI is moving toward the human side of the renovation wave — expect future work on just transition, tenant protection, and scaling one-stop-shop models across member states.

How they like to work

UIPI always participates as a consortium partner, never as coordinator — consistent with their role as a policy and advocacy voice rather than a technical lead. With 101 unique partners across 20 countries in just 9 projects, they operate in large, diverse consortia (averaging 11+ partners per project). This broad network makes them a well-connected gateway to the European property owner community, useful for any consortium that needs end-user representation or policy dissemination.

UIPI has collaborated with 101 distinct partners across 20 countries in 9 projects, reflecting very broad European reach. As a Brussels-based association, they connect consortia to national property owner associations across the EU.

What sets them apart

UIPI occupies a rare niche: they are the organized voice of European private property owners in EU research projects. While most consortium partners bring technical, engineering, or academic expertise, UIPI brings direct access to the people who actually decide whether to renovate their buildings. For any project that needs real-world adoption by homeowners or landlords, UIPI provides legitimacy, policy insight, and a dissemination channel to millions of property owners across Europe.

Highlights from their portfolio

• ABRACADABRA
  Their highest-funded project (EUR 171,219) and earliest H2020 involvement, focused on a creative volumetric addition approach to deep retrofitting of existing buildings.
• NRG2peers
  Represents a strategic pivot from building renovation into peer-to-peer energy communities, blockchain, and gamification — showing UIPI expanding beyond traditional property management concerns.
• ENPOR
  Directly tackles the politically sensitive split-incentive problem between landlords and tenants in energy poverty — a core issue for UIPI's constituency.
