Description

Heat4Cool proposed 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 developed, integrated and demonstrated 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.
This retrofitting solution together with a closer interaction between building monitoring, demand/respond supply to match, weather forecast and HVAC activation/control through a Self-Correcting Intelligent Building Energy Management Systems (SCI-BEMS) saved at least 10% of energy consumption.
The project implemented four benchmark retrofitting projects in four different European climates to achieve a reduction of at least 20% in energy consumption in a technically, socially, and financially feasible manner and demonstrate a return on investment of 8 years. The Heat4Cool consortium ensured the maximum replication potential of the Heat4Cool solution by continuous monitoring of technical and economic barriers during the development and validation phases in order to present the building owners and investors with clear energy and economic evidence of the value of implementing Heat4Cool solution.
A detailed business plan was developed at the beginning of the project to strengthen the exploitation plan of the retrofitting package and set the basis for a massive replication of the demonstrated concept across Europe.
