We investigate data-driven, simple-to-implement residential environmental models that can serve as the basis for energy saving algorithms in both retrofits and new designs of buildings. Despite nonlinearity underlying dynamics, using Koopman operator theory framework this study we show a linear second order model embedding, captures physics occur inside single or multi zone space does well when...

A control-oriented quality modeling approach is proposed for sewer networks, which can represent dynamics using simple equations in order to optimize pollution load from combined overflows large scale network real time. Total suspended solid has been selected as the indicator, regarding it easy be estimated through measuring turbidity and correlated with other indicators. The model are independ...
