Abstract

This paper looks at low temperature hot water distribution and heat recovery as an approach that can be used in health care and laboratory applications to reduce the energy intensity of the HVAC reheat and preheat process. The concepts presented could easily be applied to reheat and preheat processes in other applications such as semiconductor and pharmaceutical clean rooms. The paper also looks at radiant slabs as an opportunity to use low temperature hot water for comfort heating applications in new construction. A case study of an application in a health care environment is included.
