HYBUILD is an EU Horizon 2020-funded project, coordinated by COMSA CORPORACIÓN, which will develop two innovative compact hybrid electrical/thermal storage systems for stand-alone and district connected buildings.

HYBUILD aims at developing cost-effective and environmental-friendly solutions, while ensuring comfort conditions in residential buildings located in two different climates: Mediterranean climate where cooling is critical; and Continental climate where a stronger focus is put on heating demand.

Funded by the European Union

The HYBUILD project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement n° 768824.

Horizon 2020 is the financial instrument implementing the Innovation Union, a Europe 2020 flagship initiative aimed at securing Europe’s global competitiveness. It is the biggest EU Research and Innovation programme ever. It promises more breakthroughs, discoveries and world-firsts by taking great ideas from the lab to the market. 


Integration of a compact two fluid PCM heat exchanger into the hot superheated section of an air source heat pump cycle for optimized DHW generation

A new HYBUILD conference paper was presented at the 25th IIR International Congress of Refrigeration, Montreal, Canada, August 24−30, 2019. This contribution presents a concept for the direct integration of a refrigerant/water Heat Exchanger (HEX) with a Phase Change Material (PCM) in the hot superheated section of an R32 – air source compression Heat Pump …

Phenomenological modelling of phase transitions with hysteresis in solid/liquid PCM

A new HYBUILD paper has been released in the Journal of Building Performance Simulation. Technical-grade and mixed solid/liquid phase change materials (PCM) typically melt and solidify over a temperature range, sometimes exhibiting thermal hysteresis. Three phenomenological phase transition models are presented which are directly parametrized using data from complete melting and solidification experiments. They predict …

FRESNEX collectors installed at the HYBUILD Spanish demo site

At the HYBUILD Spanish demo site located in Almatret, solar collectors provided by FRESNEX have just been successfully installed. Local stakeholders, in particular from the town of Almatret and from University of Lleida, have been trained on the overall system functioning and on its control / tracking system. During the upcoming months, this system will be …
