Abstract

This paper describes the pattern of electricity consumption from total and selected domestic appliances at a typical terrace house in Malaysia. The measured appliances can be classified into four groups on the basis of pattern of use which are ‘standby’ (TV), ‘active’ (massage chair, charger of hand phone, laptop and power bank, washing machine, air-conditioners, iron, standing fan, shower heaters, rice cooker, toaster, microwave), ‘cold’ (refrigerator) and ‘cold and hot’ (water dispenser). The major contribution of monthly electricity consumption comes from ‘cold’ appliances that consume 118.8 kWh/month followed by ‘active’ appliances that consume 87.8 kWh/month and ‘cold and hot’ appliance with 52.5 kWh/month. ‘Standby’ appliances shown a small contribution to the total electricity with 0.9 kWh/month. The amount of energy consumed depends on time-of-use, power characteristics of particular appliances as well as occupancy period.

Highlights

Energy demand in Malaysia continues to surge due to rapid infrastructure development and economic growth
RESEARCH METHOD The field measurement was conducted in a two-storey terrace house from middle-income of five family members that located in Selangor, Malaysia from September 2016 to August 2017 for 365 days
The reliability of the measured data was confirmed through comparison with monthly electricity consumption from the energy meter of electricity supply in Malaysia known as Tenaga National Berhad (TNB)

Summary

Introduction

Energy demand in Malaysia continues to surge due to rapid infrastructure development and economic growth. The energy consumption was recorded increase to 7.5% in 2012 and was foreseen to rise for the upcoming years [1]. It indicates that the power sector alone has come up with 54.8% of the total CO2 emissions in 2013 [2]. In Malaysia, residential buildings are responsible for 21% of total electricity consumption [4]. On the basis of these findings, comparative study in [5] concluded that electricity consumption without space and water heating will have an impact on the appliances ownership and socio-demographics. The authors from [6] in their study stated that specific appliances as one of the determinants that significantly impact the usage with higher consumption
