Abstract: This paper proposes a modified energy saving glass (MESG) for energy management of air conditioning system and transmission improvement of in-service and applicable frequency bands. For a typical float glass, the transmission of IR signals is about 98.2% which diminishes to 43% by the deployment of an ESG. Utilization of ESGs although yields energy consumption reduction, but simultane...
