Based on asset data regarding the building and on corresponding performance data, improvement measures related to a consumable resource in the one or more buildings are determined using a computer system configured for analyzing the asset data and the respective corresponding performance data based on internal and/or external key performance indicators and rules provided by a database.
Various embodiments may include a method and/or arrangement for assigning the spatial position to a device, in particular in the context of the commissioning of the device (e.g. field device, actuator, sensor), wherein a positioning system is used to determine the spatial position of a mobile communication terminal located in the spatial vicinity of the device. The mobile communication terminal (e.g. smartphone) is configured to transmit the spatial position to the device and such that the transmission of the spatial position from the mobile communication terminal to the device only takes place when the device has been identified as an authorized receiver prior to transmission.

Building device having an address programming interface
A building device with a front accessible address programming interface is provided. The building device includes a mounting base having front and rear surfaces. The front surface defines two connector channels extending towards the rear surface. The connector channels are spaced apart and sized to each receive a respective prong of a programming device connector plug. The building device further includes external terminals disposed on the rear surface, internal terminals, a group of normally closed switches having a common control input, and an actuator. Each switch connects an external terminal to a respective internal terminal when the common control input is deactivated to provide a network connection. The actuator is connected to the common control input and disposed such that the connector plug engages the actuator to activate the common control input of the switches when each of the connector channels receive a respective prong of the connector plug.
