Abstract
PCM wallboards were used in combination with PCM underfloor heating system.Price-based method was experimentally used to perform peak load shifting.Solar irradiation was used to minimize energy consumption.A cost and energy saving up to 35% and 44.4%, respectively, were achieved. Phase change materials (PCMs) are used with various building materials to increase their thermal mass. This research is on the application of PCM in the form of DuPont Energain® wallboards in combination with an underfloor heating system incorporating PCMs. 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.
