Certain systems and methods herein are directed to features of accessing and/or improving building system efficiency and supporting linear asset networks, including aspects involving IoT (the Internet of things). For example, some embodiments may include ways to measure occupant comfort, ways to conserve energy in heating and cooling linear asset networks, measure the efficiency of linear assets for energy and water delivery and consumption, improve machine efficiency by increasing maintenance effectiveness and many others. The safe fusion of sensor data from human devices, machines, linear assets and space provides a new correlated collection of data for analysis and optimization of building control systems. Innovations herein may pertain, inter alia, to water, gases, liquids, and buildings including commercial, homes, industrial and transportation-oriented spaces such as ships, trains, airplanes, mobile homes.
