heat use efficiency

For testing different engineering solutions for energy-efficient buildings, a low-energy building was built at the University of Tokyo as a pilot project. In this building, a radiant heating/cooling ceiling panel system is used. This study aims to not only clarify the system performance but also to share our experience and results for them to serve as a reference for other similar projects. Here, the system performance in relation to its heating/cooling capacity and thermal comfort has been evaluated.
