Abstract
In Pakistan, data for household electricity consumption are available in the form of monthly electricity bills only, and, therefore, are not helpful in establishing appliance-wise consumption. Further, it does not help in establishing the relationship among the household electricity consumption and various driving factors. This study aimed to unlock the household electricity consumption in Pakistan by analyzing electricity bills and investigating the impact of various socioeconomic, demographic, and dwelling parameters and usage of different appliances. The methodology adopted in this study was survey-based data collection of the residential sector. For this purpose, data were collected from 523 dwellings through surveys and interviews in Mirpur city. The results of the data analysis revealed that the average household electricity consumption is 2469 kWh/year with an average family size of seven and an average floor area of 78.91 m2. Based on possession of various appliances, the households were categorized into four types and their consumption patterns were established and compared. Air Conditioned (AC) houses consume 44% more electricity compared to the non-AC houses, whereas an Uninterrupted Power Supply (UPS) consumes electricity equivalent to an AC. The research findings are useful for policy makers and building designers and are discussed in the conclusion section.
Highlights
Energy is often regarded as the backbone of a country’s economic and human development [1]
Annual electricity consumption was analyzed in detail and its benchmarks in the form of kWh/m2 and kWh/person were established and discussed for the Air Conditioned (AC) and non-AC homes
A survey-based study attempted to unlock the details of annual electricity consumption of residential buildings of Pakistan
Summary
Energy is often regarded as the backbone of a country’s economic and human development [1]. Global energy demand has been increasing exponentially at a yearly average rate of 2.2% since 1965. The world energy outlook has already predicted it to increase by 30%. Between today and 2040 [2,3]. 30–40% percent of the total energy is consumed in the building sector, of which residential buildings consume three-fourths of the total buildings’ consumption [4]. The varying climatic conditions with increasing population, economic development, and human growth have resulted in an increased demand for energy in the building sector. Energy-efficient and sustainable buildings are imperative to build an equilibrium between the present and future energy demands of a country
