A model for efficient consumption of electricity in residential buildings

Abstract

Abstract This paper reviews various applications of Radio Frequency Identification (RFID) technology and proposes electricity-saving power switch enhancement model to control the operation of electrical appliances in residential buildings using radio frequency identification (RFID) system. Estimation was made on the consumption of electricity in a private apartment in Pretoria, Gauteng Province, South Africa and compared with when the RFID card-reader system is deployed. The percentage energy saving in a year was calculated to be approximately 29 %. The possible energy savings for a period of 30years is estimated and the return on investment (ROI) determined. The authors concluded by making a case for a state policy on RFID energy efficiency technology.
