Feasibility Study on the implementation of room control automation to realize smart green buildings

Abstract

Currently, the level of carbon dioxide (CO2) emissions is at the highest level. One of the causes is the waste of electricity used. One of the most significant contributors to electrical energy consumption is in the High Rise Building (HRB) sector. This paper proposed an automation system in Heating, Ventilation, and Air Conditioning (HVAC) systems, lightings systems, and electronic systems, especially in the guest room area, where electrical energy consumption very much depends on the guest’s behavior. The purpose of the proposed system is to save energy and to realize smart green buildings. The result shows that the proposed system provided an average energy saving of 294.882 kWh per month. This system could save the cost of electricity bills by 21,38% each month. Those results confirmed that the implementation of a room control automation system is feasible to realize smart green buildings.
