Abstract

Hotel buildings are currently among the largest energy consumers in the world. Heating, ventilation, and air conditioning are the most energy-intensive building systems, accounting for more than half of total energy consumption. An energy audit is used to predict the weak points of a building’s energy use system. Various factors influence building energy consumption, which can be modified to achieve more energy-efficient strategies. In this study, an existing hotel building in Central Taiwan is evaluated by simulating several scenarios using energy modeling over a year. Energy modeling is conducted by using Autodesk Revit 2025. It was discovered from the results that arranging the lighting schedule based on the ASHRAE Standard 90.1 could save up to 8.22% of energy consumption. And then the results also revealed that changing the glazing of the building into double-layer low-emissivity glass could reduce energy consumption by 14.58%. While the energy consumption of the building could also be decreased to 7.20% by changing the building orientation to the north. Meanwhile, moving the building location to Northern Taiwan could also minimize the energy consumption of the building by 3.23%. The results revealed that the double layer offers better thermal insulation, and low-emissivity glass can lower energy consumption, electricity costs, and CO2 emissions by up to 15.27% annually. While adjusting orientation and location can enhance energy performance, this approach is impractical for existing buildings, but this could be considered for designing new buildings. The results showed the relevancy of energy performance to CO2 emission production and electricity expenses.
