The project involves a new nursery school designed with energy-saving criteria, including a highly efficient building envelope, an underground ventilation shaft system, and the installation of solar thermal panels.

Solar thermal energy captures the sun’s radiation to generate heat for domestic hot water or space heating. These systems are typically closed-loop. An antifreeze liquid circulates through tubes inside the collectors and is heated by solar radiation. The hot liquid then flows through the primary hydraulic circuit to a storage tank, where it transfers heat to the building’s system through a heat exchanger.

Solar thermal energy is generally used as a supplementary source for heating or domestic hot water.
