Building BIOS Architecture

Resource Availability Services represent the presence, quality, capacity, and operational status of resources required by building systems.

Resources may include:

electrical power;

backup power;

potable water;

drainage capacity;

ventilation air;

heating and cooling capacity;

communication bandwidth;

computing capacity;

data storage;

time synchronization;

structural support capacity;

emergency resources;

human or robotic service access.

Each Resource Record shall identify:

resource type;

provider;

consumers;

available capacity;

committed capacity;

reserve capacity;

quality parameters;

current state;

expected duration;

redundancy;

limitations;

affected location.

The BIOS shall distinguish between:

nominal installed capacity;

certified capacity;

currently available capacity;

allocated capacity;

remaining capacity;

degraded capacity;

unavailable capacity.

Resource allocation shall respect priority. Safety and emergency functions shall receive priority over comfort, optimization, or optional services where applicable.

Resource Availability Services shall not replace physical protective devices or utility controllers. They provide coordinated information and permissions to authorized systems.

Loss or degradation of a resource shall trigger dependency analysis and state transitions for affected consumers.
