These guidelines dispel the confusion about matching variable frequency drives (VFD) and motors to fans and pumps that are typically encountered in commercial building applications. While the motivation to increase energy efficiency could be financial (reduced energy costs) or ethical (reduce greenhouse gas emissions associated with power production), it is taken for granted that VFDs are an easy way to improve energy efficiency in a motor application. And with these noble intentions in mind, the engineer will specify a VFD for his client. Oftentimes, that isn't the end of the story for the engineer.
A better understanding of power factor, harmonics, electrical distribution systems, and the utility’s billing practices will help reduce electric bills.
Here are practical evaluation criteria for selecting LED lighting for indoor, ambient applications.
Building officials from across the nation voted to support historic gains in the energy efficiency of building energy codes at the Final Action Hearings for the 2012 International Energy Conservation Code (IECC). As a result, the energy efficiency of America’s 2012 model energy code for new homes and commercial buildings will likely achieve the 30% boost sought by the U.S. Dept. of Energy, the U.S. Conference of Mayors, the National Assn. of State Energy Officials, Congress, and the broad-based Energy Efficient Codes Coalition (EECC).
The 2010 MEP Giants provide insight on the state of the engineering industry and what to look for in 2011.
The Seattle area’s new, high-capacity next generation South Hill North Data Center in Puyallup, Wash., has received the Technology Development of the Year Award from NAIOP.
In 2010, engineering firms focus on energy-efficiency initiatives this year, while investing heavily in the continued development of their in-house engineers.
An “almost perfect” firestopping system isn’t good enough when a fire starts in a building. There are several reasons for providing firestopping for wires and cables. It may be a requirement of the building code, or of an insurance carrier or a building owner that wants to minimize the risk associated with fire spreading from one part of the building to another.
This video covers retrocommissioning best practices and the keys to an energy-efficient commercial building.
Suppose you are a generator service organization, maintaining customers’ equipment scattered across your state. Let’s further suppose you have extensive knowledge of the historical performance of every machine and know the battery voltage, fuel level, and controls condition of each generator, and that information is always current. Armed with that information, a well-trained technician could readily identify the machines that are at risk of operational failures, and prioritize the replacement of weak batteries or call in fuel where needed, to avoid the failure that is certain to happen without his proactive intervention.
