  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 of each type. Modeling household energy consumption is
the first step in exploring the possible demand response and load reduction
opportunities under the smart grid initiative. Residential electricity load
profiling includes the details on the electrical appliances, its energy
requirement, and consumption pattern. The model is generated with a bottom-up
load model. Simulation is performed for daily load profiles of 1 or 2 rooms, 3
rooms, 4 rooms and 5 rooms public housing. The simulated load profile is
successfully validated against the measured electricity consumption data, using
a web-based Customer Energy Portal (CEP) at the campus housings of Nanyang
Technological University, Singapore.
