Evaluation of the energy impact of PCM tiles in an Airport Terminal Departure hall [PDF]

open access: yes, 2013
Copyright @ 2013 CIBSEIn most past studies, passive PCM (phase change materials) systems have been tested for relatively small office spaces where the airflow is of minimal consequence in the overall energy consumption of the space.
