Radiant Cooling System (Energy, Comfort and Cost Assessment)

Abstract

With an objective to provide thermal comfort, a well-planned and efficient HVAC system is of
foremost importance. HVAC being the highest contributor of power consumption in the
building (40% approximately), there is a need of a system which induce thermal comfort and
reduce the power consumption, thereby improving the indoor environmental quality. Radiant
system works on the transfer of heat through radiation which provides maximum thermal
comfort and reduces the consumption of electricity up to 50-60%. Hence, this paper focuses
on the working principles of a radiant system and an overall cost and quality assessment, its
comparison from VAV system, and drawing conclusions from case studies.
