Abstract
To promote efficient use of electrical energy, technology-based solutions, along with their corresponding user acceptance assessments, have been seen to facilitate goal fulfillment concerning desired functionality and expected benefits, in an open innovation fashion. This paper simultaneously develops an electrical energy consumption monitoring system (EECMS) device that shall monitor and control the use of energy in real-time and assesses its acceptability to users according to the extended technology acceptance model (TAM) approach. This proposed EECMS device is tested in an academic institution in the Philippines, and it is found that the device can function as desired as well as render a significant favor from its users according to additional key constructs. As such, future developments of the device are encouraged to enhance key constructs identified as suitable for future adoption.
Highlights
The use of energy has become an integral part of growing an economy [1]
EECMS device is designed to be a low cost, user-friendly electrical energy consumption monitoring system composed of hardware and software which can measure, transmit, record, and store real-time electricity consumption via the internet using Google spreadsheet as its data backend
The need to manage energy consumption, in academic institutions, has become an urgent concern for policymakers to simultaneously optimize energy efficiency and maintain satisfaction among users. Such effort on energy optimization is addressed by introducing technology-based devices that can support the monitoring and control of energy consumption or by investigating the factors that influence the adoption and acceptance of technology-based devices
Summary
The use of energy has become an integral part of growing an economy [1]. As increasingly new energy sources are explored along with the open innovation of energy industry technology, macroeconomic growth is understood to rise [2]. With the favorable shift of economic status, the process of urbanization, standards of living, and even climate change perspectives have prompted the variation in energy consumption [3]. This premise holds, especially in the case of developing countries where rural household energy consumption takes up a significant portion of total energy consumption. There are different opportunities for reducing electricity consumption in buildings, but identifying and quantifying them is often regarded as time-consuming or expensive, in single-family households [36]. Neither option can track the changes in energy (electric) usage of the individual appliances as well as the aggregated load over time, not to mention its relatively expensive acquisition cost
