Can we learn from heritage buildings to achieve nearly zero energy building and thermal comfort? A case study in a hot climate

ABSTRACT

Heritage buildings were built in a period when energy equipment for cooling and heating did not exist. This research focuses on the way in which we could benefit from such constructions to impact today's buildings and society. The investigation will consider a number of elements such as thermal mass, day-lighting and thermal comfort in comparison with a new simulated building which has the same design as the Heritage one. The research was conducted using the energy simulation tool TAS EDSL and on site measurement. In addition to that, an advanced thermal imaging camera was used in the study of physical characteristics of the building. The study revealed that applying methods of Heritage buildings to modern buildings, such as the use of thermal mass and natural ventilation, can have a considerable impact on energy consumption and thermal comfort for users. It can reduce indoor temperature up to 5°C. It was also found that the use of natural ventilation is linked to indoor thermal comfort. Large area of glazing is recommended to be used in such region when it is applied in the proper way.
