Hospitals face significant expenses in maintaining the optimal indoor climate needed for patient care. By integrating advanced thermal systems—such as solar thermal collectors and waste heat recovery—facilities can capture renewable energy and store it for later use. This approach not only reduces reliance on conventional fuels but also helps lower operating costs by making heating and cooling processes more efficient.

Seasonal thermal storage plays a key role in this strategy by banking excess heat during low-demand periods and releasing it when temperatures drop or demand spikes. This system stabilizes energy expenses, enhances indoor comfort for patients and staff, and frees up resources that can be reinvested into critical healthcare services.
