Description	Radiant heating and cooling systems use convection and radiation to control temperature between the system and its environment.
Advantages	low energy consumption Excellent in hot and dry climates Efficient lifecycle costs
Disadvantages	Complex system when integrating zone control Cooling most important in humid climates which are unsuitable Heating most important in extremely cold climates which are unsuitable
Characteristic features
Application barriers	Environmental factors such as cold or humidity cause various performance problems
