RADIANT SLAB COOLING: A CASE STUDY OF BUILDING ENERGY PERFORMANCE

Zhen Tian, James Love, Ph Candidate

Abstract: This paper introduces a case study of an existing multifloor radiant slab cooling system through simulation and field measurements. EnergyPlus was selected based on a review of currently-available simulation programs. Real weather data were used and the model was calibrated with metered energy data. Simulated energy uses and indoor thermal conditions were compared with measured data to evaluate comfort conditions and operations. The exercise revealed problems in the existing EnergyPlus low-temperature radiant cooling/heating module and some uncertainties in the simulation model. Major problems in the control of the HVAC systems were identified, and remedial measures are proposed.
