Application of Radiant Heating and Cooling in Plus-Energy Houses

Radiant heating and cooling systems present several advantages over other heating and cooling systems in terms of thermal indoor environment and energy. One of the benefits of radiant systems is that they enable integration of renewable energy resources (ground, night-time radiative cooling, etc.) into the heating and cooling systems in buildings. These advantages of radiant systems make them particularly attractive to be used in plus-energy houses. This presentation summarizes the design, simulation and year-round measured performance of two plus-energy houses equipped with radiant systems. Different performance aspects of the houses will be covered and improvement suggestions will be provided.
