This paper aims to identify the potential for industrial-scale solar thermal (ST) systems for the integration into a hospital’s ventilation reheat systems. It describes the design, performance, and economics of a solar thermal-assisted heating application into a hospital’s ventilation reheat system in California, offsetting the use of common petroleum-burning boilers to produce the hydronic heating for ventilation reheat in a hospital. Healthcare facilities need to meet a set of standard ventilation requirements and air change per hour hates – typically higher than those found in most other buildings – and their large heating, ventilation, air conditioning (HVAC) and water heating systems consume a substantial amount of energy. This conditioning is commonly referred to in the industry as “reheat” and is accomplished from the on-site combustion of natural gas. Research uncovered that one of the biggest end-uses of energy within hospitals is re-heat, which can account for 42 percent of a hospital’s energy consumption. A solar thermal heating system supplies heat energy to the ventilation reheat system for a 150 bed community hospital. The solar thermal collector field with 2,520m2 gross area provides an annual solar yield of 2,286 MWhth. With the available roof space for collector placement, the solar fraction is 33% and the payback time of the system is <6 years. Normalized figures of solar yield, economics, energy savings, and CO2 reductions are being presented which can be applied as a more ecological alternative to ventilation reheat in other healthcare facilities.
