This part of ISO/IEC 14543 presents methods for overall building management of the home electronic system (HES) architecture. The interaction of building and home control systems requires a demarcation between building manager versus tenant responsibilities.
A method for implementing agreements between building managers and tenants regarding user access to and control of applications via a firewall is specified.
This technical report augments series ISO/IEC 14543, the architecture of HES (Home Electronic System), in order to accommodate both home and building automation in a mixed use building. Both systems may coexist in a building with shops, offices and apartments. Some systems are applicable to the whole building versus the systems which are applicable to individual apartments and offices only. In some cases these systems need to interact.
This technical report proposes a logical model for linking building and home control systems even if the two use different physical arrangements of components.
The basic recommendations are:
- allow for distinct and separate building and home automation control systems, possibly supplied by different manufacturers;
- define clear points of connection between building and home control systems;
- limit the number of points of connection between building and home control systems, preferably to one per home system;
- accommodate systems that provide building tenants with user control of local systems. This favors an architecture where products can be designed for the user to override control decisions within parameters agreed with building management. Such actions are exercised by the building automation system and affect local systems. This enhances user safety and user privacy.
- provide seamless links between systems that are based on different architectures, that incorporate different communications protocols, and that may be purchased from different manufacturers.
