Abstract
This paper provides a thorough examination of Radiant Heating and Cooling (RHC) systems in the context of sustainable building practices. It covers the evolution, theoretical foundations, technological advancements, financial considerations, and practical uses of RHC systems. A comprehensive historical overview, tracing the evolution of RHC from ancient times to its current state, highlighting significant innovations that have greatly influenced its application in modern architecture. The scientific principles of thermal comfort, including Mean Radiant Temperature (MRT) and thermal asymmetry, which play a crucial role in the design and effectiveness of RHC systems has been explored. This article delves into recent technological advancements in RHC systems, including advanced control strategies and integration with Displacement Ventilation (DV) systems, enhancing both thermal comfort and energy efficiency in sustainable architecture. One important discovery is the substantial energy savings that can be achieved with RHC systems. Studies conducted by Lawrence Berkeley National Laboratory (LBNL) have shown that RHC systems can lead to energy savings of up to 30%, depending on the climate zone, with greater reductions (up to 42%) observed in hot, dry regions. Significant savings were observed in cool, humid regions, with reductions of 17%. In hot, dry areas, even greater reductions of up to 42% could be achieved. The financial analysis uncovers the cost-effectiveness of RHC systems, showcasing their potential for long-term savings despite the higher initial installation costs compared to traditional HVAC systems. The paper concludes by emphasising the importance of RHC systems in promoting energy-efficient, sustainable building practices and their substantial impact on reducing greenhouse gas emissions and achieving net-zero energy goals. This comprehensive exploration of historical context, theoretical analysis, technological exploration, and practical application offers a well-rounded perspective on RHC systems as a fundamental aspect of contemporary sustainable architecture.
