Application of PCM underfloor heating in combination with PCM wallboards for space heating using price based control system

Phase change materials are used with various building materials in order to increase their thermal mass. This research is on the application of phase change material in the form of DuPont Energain® wallboards in combination with an underfloor heating system incorporating phase change materials. An experimental study was carried out using two identical test huts at the Tamaki Campus, University of Auckland. Results using a price-based method showed electricity savings in both consumption and cost of up to 35% and 44.4% respectively.
