oBIX (for open building information exchange) is a standard for REST full web services based interfaces to building control systems.

1. BIX

2.  oBIX (for open building information exchange) is a standard for REST full web
services based interfaces to building control systems.
 Building control systems include those electrical and mechanical systems that
operate inside a building.
 Including heating and cooling, security, power management , safety alarms, A/V
event management, theatre lighting, medical gas distribution and many others.

3.  oBIX is a web services interface because it does not necessarily allow deep
interactions with the underlying control systems.
 This interface can enable communication between enterprise applications
and embedded building systems as well as between two embedded building
systems.
 Facilities and their operations to be manages as full participants in
knowledge based businesses.

4.  oBIX is being developed within OASIS.
 The organization for the advancement of structured information standards.
 Version 1.0 was completed as a committee standards in December 2006.

5.  oBIX provides a publicly available web services interface specification that can be
used to obtain data in a simple and secure manner from.
 HVAC
 Access control
 Utilities and
 Other building automation systems
 And to provide data exchange between facility systems and enterprise
applications

6.  Points: representing a single scalar value and it’s status – typically these map to
sensors, actuators, or configuration variables like a set points.
 Alarming: modelling, routing, and acknowledgment of alarms. Alarms indicates
a condition which requires notification of either a user or another application.
 Histories: modelling and querying of time sampled point data. Typically edge
devices collect a time stamped history off point values which can be fed into
higher level applications for analysis.

7. To keep a public space open in the evening may require a range of a calls to different
organizations within a buildings, each initiating an interaction with a separate building control system.
To schedule a public meeting tonight from7:00 to 9:00, the organisation may have to:
 Call security to warn the guard, and keep the
o Access control system working in day-time mode until 9:30.
o The guard may also need to disable.

8.  Call maintenance to make sure the room’s
o Environmental controls are set properly for the event.
o This may include over-cooling (or heating) the room in advance to make sure that the room
will be comfortable when filled with the anticipated numbers of callers.

9.  Call the media support group to make sure the
o A/V event management system is properly warmed up before the event.

10.  In an oBIX-enabled building, these features are accomplished by instead sending an
calendar meeting invitation to the room and/or its support systems.
