EVALUATING HARDWARE BUI LDI NG CONTROL I N THE CLOUD

Proceedings of BauSIM

Abstract

Many energy inefficiencies in buildings can be attributed to errors in control logic. This may be because of faulty hardware or incorrect programming. Within the context of a framework for testing building control, this paper evaluates controller operation using only monitored data. For a real building in operation, the performance of its control is analyzed with KPIs, and the causes of control errors are investigated automatically in the cloud. Possible improvements are suggested and the control code is updated using components from the open-source automation library AixOCAT. The process results in a better understanding of system behavior for the user.
