Microclimate and its impact on hotel building energy saving performance in tropical coastal city.

Microclimate is increasingly influencing urban buildings, energy use, and sustainability. Coastal tropical regions were almost affected by this phenomenon. A hotel building model is presented for a study of urban heat islands (UHIs) and urban thermal environment. There should be measures taken to reduce the energy demands of hotel buildings, which tend to consume more energy than other types of public buildings. In this paper, weather data analysis and building simulation are used to predict energy consumption based on microclimates. Using the example of an existing three-star hotel in Makassar, Indonesia, energy simulations were conducted using the eQuest software. The surface properties of building façades affect the thermal performance of buildings and might also affect the consumption of electricity. Results indicate that schedules of internal loads impact the accuracy of a hotel building's model most, followed by occupancy rate and coefficient of performance (COP) of chillers. According to our findings, Makassar microclimate variations should be taken into account when developing urban energy planning and building energy codes and standards.
