DTERBIM partner Hellenic Passive House Institute (HPHI) took to the stage at the 28th International Passive House Conference, where researchers Ilektra Mancini and Dimitris Pallantzas presented HPHI’s study on energy poverty in metropolitan cities.

The ongoing research combines district energy and comfort simulations with extensive fieldwork, including questionnaires, monitoring, energy studies, and thermography, across more than 100 buildings in Greece. The aim is to calibrate digital modelling with real-time data to build a more accurate picture of how energy poverty manifests at the urban scale.

At DTERBIM, we will play a key role in the next stages of this research. Our early design and assessment tools, together with our BIM models, will provide guidance to decision-makers and policymakers.

About the Hellenic Passive House Institute

The Hellenic Passive House Institute supports stakeholders across the building sector and the wider public by providing impartial, comprehensive information on the design and implementation of Passivhaus buildings.

Its activities include producing informational materials, conducting seminars and scientific research, and certifying completed Passivhaus projects. HPHI also delivers advanced training, supports the design and construction of new and existing buildings, and actively contributes to national and EU policy dialogue, promoting energy efficiency as a cornerstone of climate action.

In DTERBIM, HPHI leads the Greek pilot in Pallini, Athens, which will house a kindergarten and an elementary school, both designed and built as certified Passivhaus and Positive Energy Buildings.

Working closely with Greek partners Urban Soul Project and SmartFlex, HPHI bridges digital design and real-world construction by integrating BIM and Passive House methodologies. Under its coordination, approximately 80% of the pilot’s design will be developed through BIM and DTERBIM digital tools. HPHI also contributes to the development of our Early Design Tool, supporting data-driven design optimisation and digital innovation for educational buildings.
