CABA - Continental Automated Buildings Association

Continental Automated Buildings Association (CABA) is a not-for-profit industry association dedicated to the advancement of intelligent building technologies in North America.


The organization is supported by an international membership of nearly 400 companies involved in the design, manufacture, installation and retailing of products relating to building automation systems.


CABA's mandate includes providing its members with networking and market research opportunities. CABA also encourages the development of industry standards and protocols, and leads cross-industry initiatives.


The organization was originally founded in 1988 as the Canadian Automated Buildings Association.



Celsius is a scale and unit of measurement for temperature. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale two years before his death.


Scientific unit of temperature.

Conversion from
kelvins degrees Celsius °C = K − 273.15
degrees Celsius kelvins K = °C + 273.15
kelvins degrees Fahrenheit °F = K × 1.8 − 459.67
degrees Fahrenheit kelvins K = (°F + 459.67) / 1.8

Chilled Beam

Type of convection HVAC system designed to heat or cool buildings. Pipes of water are passed through a "beam" (heat exchanger) which is suspended a short distance from the ceiling. As the beam chills the air around it, the air becomes denser and falls to the floor. It is replaced by warmer air moving up from below, causing a constant flow of convection and cooling the room.


Types of Chill Beams:

        Passive Chilled Beams are similar to finned/tube radiators and are typically positioned within the ceiling cavity. Perforations allow warm air to flow from the occupied space up to and inside the beam. Operated completely by free convection, the warm air rises to the beam, is cooled, and then descends naturally without any fans.


        Active Chilled Beams use ventilation air, supplied through ducting in the beam, and provide ventilation air through induction nozzles which create a pressure differential across a cooling coil, inducing air flow across the coil and supplying cool air back to the occupied space. Because they use powered air movement, active beams can also be used for heating by supplying hot water to the heat exchanger.


        Multi-Service Chilled Beams are an extension of the active chilled beam concept that may also act as a conduit to supply other building services such as lighting, network wiring, fire protection, Building Automation System sensors, etc.



Wiring path for electricity, including conductors, load and circuit protection.


Circulator pump

A type of pump used to circulate gases, liquids, or slurries in a closed circuit. They are commonly found circulating water in a hydronic heating or cooling system.


Circuit Breaker

Resettable safety device to prevent current flow or prevent excess current flow.


Circular pump

A specific type of pump used to circulate gases, liquids, or slurries in a closed circuit. Circular pumps are commonly found circulating water in a hydronic heating or cooling system. Because they only circulate liquid within a closed circuit, they only need to overcome the friction of a piping system. Circulator pumps as used in hydronic systems are usually electrically powered centrifugal pumps.



An application or device acting as a requestor or user of data in networked systems.


Commercial Energy Codes

Click to Launch Building Energy Code Tool [flash]Building codes are a set of rules that specify the minimum acceptable level of safety for constructed objects such as buildings and structures. The main purpose of the building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures.


Building codes are generally intended to be applied by architects and engineers, but are also used for various purposes by safety inspectors,, commercial developers, contractors and subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants, etc...

A cooling tower is used to discarding heat from a chiller. Water-cooled chillers are normally more energy efficient than air-cooled chillers due to heat rejection to tower water at or near wet-bulb temperatures. Large office buildings, hospitals, and schools typically use one or more cooling towers as part of their air conditioning systems.
