Building Systems Commissioning can provide Building Managers very beneficial rewards; especially when they include building systems services to critical facilities, such as data centers or other 24 hour services.
Following are highlights of an effective commissioning plan to assist maintenance management in making the demonstration as effective as possible:
Interruption of electrical service is the most common source of operating crises for most businesses; thus, the most reliable demonstration of the building system status is a “Whole Building Shut-Down”; which establishes the performance of all equipment and systems under emergency power AND, AS IMPORTANT, how the systems respond to the return of utility power.

Nature of the Work
HVAC Jobs provide services to building heating and air-conditioning systems; to control the temperature, humidity, and the total air quality in buildings. Refrigeration systems may be part of the building system, or can serve freezers and coolers that support specialty areas of the facility, such as food service and machines that require direct cooling.
Heating, air-conditioning, and refrigeration service mechanics and installers—also called HVACR Techs—install, maintain, and repair such systems.
Heating, air-conditioning, and refrigeration systems consist of many mechanical, electrical, and electronic components, such as motors, compressors, pumps, fans, ducts, pipes, thermostats, and switches. In central forced air heating systems, for example, a furnace heats air, which is then distributed through a system of metal or fiberglass ducts. Technicians maintain, diagnose, and correct problems throughout the entire system. To do this, they adjust system controls to recommended settings and test the performance of the system using special tools and test equipment.
Technicians may specialize in doing heating work or air-conditioning or refrigeration work. Some specialize in one type of equipment—for example, hydronics (water-based heating systems), solar panels, or commercial refrigeration. [click to continue…]
