Building Energy Management And Consumption Are Receiving More Attention As A Result Of The Depletion Of Energy Resources And Rising Energy Demand. To Track And Manage Energy Use, A Variety Of Building Energy Management (BEM) Software Platforms Are Offered For Sale. The Performance Of These Platforms Is Restricted By The Hardware Specs Because They Are Housed On The Actual Hardware Inside The Building. Cloud Computing Arose As A Solution To This Constraint, Enabling The Deployment Of Software At A Remote Site With Scalable Hardware Resources. Such A Cloud Platform Can Be Used By Traditional BEM Software To Provide Scalable And Maintenance-free Installation. BEM Software Needs A Device That Supports Remote Accessibility Since It Lacks Direct Communication To Building Sensors And Controllers When It Is Hosted On A Remote Cloud Platform. Since Most Devices Are Connected To Local Area Networks, Network Address Translation (NAT)-Traversal Requires An Extra Functional Layer To Be Placed On Top Of The Communication Stack. This Feature Is Built Into Scalable Software That Connects To Network Devices And Serves As A Gateway For Cloud-based BEM Software To Access Local Area Network Devices. This Gateway Translates Any Message Provided To It Into The Appropriate Device Protocol.
