HVAC Inspections Commissioning – Building & Energy Codes

HVAC Inspections and Commissioning - Building & Energy CodesHVAC Inspections Commissioning - How often have you heard someone complain about inspectors or code officials whose job it is to inspect mechanical, electrical, plumbing, and other trades work for safety and quality workmanship?

One could argue that workmanship or even design can be horrible even if the work passes a code inspection. However, chances are if the trades have any integrity they want the job to look good whether it is for the inspector or whether it is for pride and quality of work. (more…)

Chilled Water System Efficiency

Carrier Chiller w/Air Source Condenser

Chilled Water System Efficiency - Chilled water systems in HVAC are common in large commercial applications utilizing chillers to chill the water, a pumping system to pump the water (water and glycol systems are common), and chilled water coils inside air handlers or ductwork to exchange heat from the air that is distributed throughout the building for conditioning.

Direct Digital Controls DDC | HVAC Control

Direct Digital Controls DDC or DDC Systems offer a high level of control for building mechanical and electrical systems. Additionally, the modern state-of-the-art direct digital controls have the ability to offers trends of data points of HVAC/Electrical equipment. Trending can be used to increase efficiency and troubleshoot problems with mechanical equipment. DDC integration can occur with any type of mechanical or electrical system in the building.

Additionally, the system can communicate via the internet for remote monitoring and control. Alternative names are building automation systems, building management systems, and energy management systems. (more…)

Proper HVAC Fan Maintenance and Control can Save Energy Dollars

Fan Maintenance Energy Savings - According to the Department of Energy fans consume nearly 80 billion kilowatts of energy per year. Optimizing how fans work functionally in mechanical applications can reduce energy use and save energy dollars for end users.

Assuming the design engineer selected the proper fan and proper installation in the well-designed system what can a facility manager do to save energy dollars and increase performance by looking at the fan systems in their building(s)? To make a good evaluation you need to look at several different factors in fan operation.

  • Fan Control
  • Fan Performance
  • Installation
  • Ductwork
  • Fan Maintenance
