| Abstract |
The purpose of a building is to create shelter, and for that reason energy is then used for space heating or cooling. Improving the thermal comfort of a building without the excessive use of artificial means is an important step towards the mitigation of climate change and reducing energy consumption. Although better construction designs and innovations have been made throughout the years, there are still many concerns regarding energy leakage through the building envelope, especially when using conventional construction materials. In this work, an investigation on whether the Polyblocks can improve the overall thermal performance of a building system was performed. The heat transfer to the structure as well as the indoor and outdoor thermal bridging performances were examined via a thermal camera. The results indicated that the thermal resistance of the Polyblock is greater than the minimum required in the South African National Standard (SANS 204 and SANS 10 400 Part XA) for external masonry and non- masonry wall. Moreover the energy efficiency of the building would be poorer without the Polyblock as the energy required to maintain thermal comfort would be higher. This was assessed by obtaining the thermal conductivity of the Polyblock. The Polyblocks, an innovative green technology of interlocking bricks that does not required water or cement proved that energy bridging occurred where bricks come together as anticipated. |
