Heating, Ventilating and Air-conditioning systems have a significant share in the energy consumed by buildings. Development of a highly accurate thermal model is the first step in designing an efficient air-conditioning system. In this regard, this paper proposes a semi-nonlinear thermal model — ordinary differential equation with parameters as nonlinear functions of ambient temperature and cooling...
Building energy efficiency has increasing focus worldwide. The heating, ventilation, air-conditioning (HVAC) devices account for highest energy consumption in buildings in Singapore. Multipoint sensing information in the various scenario is critical to optimize the HVAC operation, and increase the energy efficiency of the air-conditioning. A software called FloVENT® is used for simulation of room...
Building load profiling plays an important part in the development of optimal energy management systems. Heating, Ventilation, Air Conditioning (HVAC) systems consume around 40% to 50% of the total energy consumed by buildings. Using this load data, optimal operation scheduling can be determined to reduce the peak energy requirement and minimize the overall energy consumption. In this paper, EnergyPlus...
The demand of electricity keeps increasing in this modern society and the behavior of customers vary greatly from time to time, city to city, type to type, etc. Generally, buildings are classified into residential, commercial and industrial. This study is aimed to distinguish the types of residential buildings in Singapore and establish a mathematical model to represent and model the load profile...

This paper carries out load profiling of Singapore housing units and office buildings using bottom-up method for peak load reduction through optimization. Housing units in Singapore are classified according to the number of rooms, ranging from one to five. Average daily, monthly and yearly electrical usage of all these units is obtained. To explore the strategies for peak load reduction, a mathematical...
