Interconnected Wiring Systems Connect a Few Electrical Devices to Many, Thereby Minimising Resource and Energy Consumption in Modern High-Rise Buildings

The primary aim of modern/innovative buildings is to reduce resource usage and increase energy efficiency, especially in specific instances, thereby contributing to minimised Carbon Dioxide (CO2) emissions. Hence, it is one of the methods to tackle the rising price of fuel oils. However, contrary to the vision of sustainable building design practice, smart or innovative buildings currently lag in resource minimisation and initial construction costs. Instead, both incurred additional resources to upgrade them into modern ones. For instance, high-rise complex buildings employ several lifts that operate and are controlled by a Variable Speed Drive (VSD), also known as a Variable Frequency Drive (VFD). The VSD controls the electrical machines’ circuit, which involves electronic switches like IGBTs, MOSFETs, GTOs, Pulse width modulation (PWM), and voltage-sourced converters (VSC) components. These components are wisely used to power asynchronous machines, replacing the traditional starting and controlling of electrical machines’ motors/actuators, and with advanced control strategies such as field-oriented control or direct torque control, efficiency is significantly enhanced through the precise regulation of energy consumption. However, despite these benefits, the approach entails higher initial costs and non-resource minimisation investments. Thus, this study proposes an alternative method that addresses these issues. The proposed study uses an interconnected, combined multiplexing method for an alternative solution to reduce initial and operational expenses, including maintenance costs.
