Use of Renewable Energy Sources for Heat and Cooling Generation in Hospitals
Keywords:biomass, cooling, geothermal energy, heating, hospitals, renewable energies, solar energy, waste heat reuse
Use of sustainable energy sources is necessary for mitigating climate change that is the most important global environmental problem in our era. The use of renewable energies and low carbon emission technologies for heat and cooling generation in hospitals has been investigated. The existing literature has been reviewed and various successful applications worldwide have been identified although the current use of renewable energies in hospitals is rather limited. Solar energy, biomass and geothermal energy have been used so far providing heat and cooling in hospitals while they can cover part or all of their heat and cooling requirements. Their technologies are mature, reliable and cost efficient while their use results in many economic, environmental and social benefits. Taking into account that hospitals are large energy consumers the use of benign energy sources reduces significantly their carbon footprint contributing in climate change mitigation and in energy transition to low carbon economy. Our work indicates that the use of benign energy sources for heat and cooling generation in hospitals is beneficial and it should be promoted.
