This thesis investigates whether the use of TMA is suitable for and of benefit to the Norwegian building industry. Power House One plans to use the same heating technology as the Sparebank1 building in Trondheim. This building uses ventilation to distribute thermal energy to the end of activating the thermal mass. The purpose of this thesis was therefore to determine whether it is more efficient to use water rather than air to distribute thermal energy. Water has a higher volumetric heat capacity than air and therefore water-carrying pipes embedded in the thermal mass should be more efficient in distributing thermal…

Thermal comfort is one of the most important factors for the success of design. Many investigations have been made since people realized the importance of energy conservation in a building. PCM is an example of such innovation in building material that helps to maintain the thermal comfort in building and also lessen the energy demand. PCM works on a principle of latent heat storage in which the material is capable of storing the heat while it reaches melting and later releases this heat in useful form. This thesis looks into the behavior of PCM when applied on different building component…
