This report is part of the California Energy Commission (CEC) EPIC project (EPIC-14-009), Optimizing Radiant Systems for Energy Efficiency and Comfort. The main goal of this research was to determine the building characteristics of projects with radiant heating and cooling and assess their real world energy use compared to standard benchmarks for building energy performance. The energy use was self-reported through surveys and utility data and is based on whole building site energy use for a minimum of 12 months. The report describes the general building characteristics including type, size, location and climate zone of 23 buildings in North America with radiant distribution systems for both heating and cooling the predominant area of the building. The study found that almost all of the 23 buildings outperformed peer buildings and national benchmarks, suggesting that radiant systems are part of the integrated approach that can lead to low energy consumption in commercial buildings. Some operator perspectives from the survey are included to inform design and operation factors regarding radiant systems.
