Greek non-profit specializing in building renovation roadmaps, energy poverty programs, and smart financing for energy-efficient buildings across Europe.
INZEB is a Greek non-profit organization focused on accelerating building energy renovation across Europe. They specialize in developing practical tools and methodologies — such as individual building renovation roadmaps, digital building logbooks, and renovation passports — that help building owners plan and finance step-by-step energy upgrades. They also work on energy poverty, supporting citizens through energy cooperatives, mentoring programs, and smart financing schemes for energy-efficient buildings in the Balkans and beyond.
iBROAD developed individual building renovation roadmaps with step-by-step recommendations, and iBRoad2EPC extended this into formal Building Renovation Passports integrated with Energy Performance Certificates.
POWERPOOR focused on empowering energy-poor citizens through energy cooperatives, crowd funding, ICT tools, and mentoring programs across cities and regions.
SMAFIN targeted smart financing implementation for energy-efficient buildings specifically in the Balkan region.
iBRoad2EPC introduced the digital building logbook concept, signaling a move toward digitized building energy documentation.
INZEB began with hands-on building renovation planning — creating customized roadmaps for individual buildings, training professionals, and field testing renovation approaches (iBROAD, 2017). By 2020-2023, their scope broadened to include the social dimension of energy transitions (energy poverty, citizen cooperatives) and regional financing mechanisms for the Balkans. Most recently (2021-2024), they moved toward policy integration and digitization, working to embed renovation passports into official EU energy certification schemes.
INZEB is moving from technical renovation tools toward policy-level integration and digital infrastructure for building energy data, positioning them for work on the EU Renovation Wave and Energy Performance of Buildings Directive implementation.
INZEB operates exclusively as a consortium participant, never leading projects, which is typical for a focused non-profit contributing domain expertise rather than managing large initiatives. With 32 unique partners across 15 countries from just 4 projects, they work in medium-to-large consortia and maintain a broad European network. Their consistent return to building renovation themes suggests they are a trusted specialist that coordinators seek out for this specific domain.
INZEB has built a network of 32 partners across 15 countries through 4 projects — a strong spread for a small organization. Their connections span Southern, Central, and Eastern Europe, with particular relevance to Balkan energy efficiency markets.
INZEB occupies a specific niche at the intersection of building renovation planning, energy poverty, and policy tools — a combination few organizations cover. As a Greek non-profit with strong Balkan connections, they bring Southern and Eastern European perspectives to building energy projects, which is valuable for consortia needing geographic balance. Their progression from iBROAD to iBRoad2EPC shows they can sustain and deepen expertise across consecutive project generations.
