Heat4Cool Project

heat4cool-logo-new-1In order to carry out energy efficient building retrofitting, new affordable breakthrough technologies and solutions at building and district scale are needed.

Heat4Cool proposes an innovative, efficient and cost-effective solution to optimize the integration of a set of rehabilitation systems in order to meet the net-zero energy standards. The project develops, integrates and demonstrates an easy to install and highly energy efficient solution for building retrofitting that begins from the Heat4Cool advanced decision-making tool (which addresses the building and district characteristics) and leads to the optimal solution combining:

(1) gas and solar thermally driven adsorption heat pumps, which permits the full integration with existing natural gas boilers to ensure efficient use of current equipment;

(2) solar PV assisted DC powered heat pump connected to an advanced modular PCM heat and cold storage system and

(3) energy recovery from sewage water with high performance heat exchangers.
