• Boilers and HVAC Building Automation Systems
  Source: http://knol.google.com/k/julian-arhire/boilers-and-hvac-building-automation/2p0090difr5q/3# With the newest state-of-the-art sensors, direct digital controls and computer driven expert systems, buildings now can be completely automated and remotely controlled. This article will review what such systems and their operators can and cannot do, what new risks can be created for the boilers in such buildings, and how to reduce and control those risks. Benefits of automation Intelligent buildings today use a building automation system (BAS) and other systems to operate HVAC, boilers, chillers, lights, elevators, building access fire protection and other systems to achieve the twin goals of efficiency and comfort. A BAS is defined here as a system of sen

• The Benefits Of An HVAC Audit
  HVAC audits can be quite complex and involve dedicated personnel, or they can be less formal and folded into a preventive maintenance (PM) program. Focusing first on the biggest energy users — chillers, boilers and fan motors — maintenance and engineering managers can develop an audit program that locates substantial savings in energy costs, savings that often will pay for any additional maintenance burden created by conducting the audits.
