dc.description.abstract | The increase in demand for energy has given huge importance to energy saving and utilization worldwide. Construction-related industries consume 40% of the world′s energy, and the general public is more concerned about comfortable living such as thermal comfort, visual comfort and indoor quality, which leads to the increase in energy consumption. Therefore, an in-depth research on building comfort and energy saving is vital. This research aims to design a low energy building with thermal comfort and indoor air quality at National Central University. Also, the space comfort and energy consumption analysis of this building will be investigated. First, the local climatic conditions in the locality of the building in various seasons is collected and then the ANSYS Fluent flow field simulation analysis is performed for the indoor and outdoor flow field spaces to understand the normal distribution of outdoor flow fields in different seasons. The outdoor flow field simulation results show that the normal wind direction around the target building is northerly in all seasons, and this is used as a reference for the indoor natural ventilation boundary setting. After verifying the indoor flow field model, it was found that the relative error was less than 3%, indicating that the flow field simulations results are accurate and a relationship between the indoor and outdoor flow fields is explored. Further, the simulation and analysis of the indoor flow field in spring, fall and winter seasons shows that the normal indoor thermal comfort and air quality standards in the building can be maintained by opening the windows of the building. But have to rely on air conditioners in the summer for indoor thermal comfort. So for the indoor comfort analysis in the air conditioning mode, the flow field simulation results show that the position of air conditioning has to be decided according to the indoor space, shape and the air outlet of the building to make the overall space more comfortable. Finally, it is found in the energy consumption simulation that the development of energy efficient lighting technology can save a lot of energy, and the energy consumption of the target building is about 17.2% lower than the electricity reference index announced by the Energy Bureau. This strategical approach followed in this research concludes that natural ventilation can be used for indoor comforts in different seasons depending upon the local climatic conditions. This research could be a reference for construction industry that position of indoor thermal comfort equipment plays a key role for efficient maintenance of thermal comfort inside building. This research is helpful in designing an energy efficient and low energy building. | en_US |
