Top 5 Consulting-Specifying Engineer articles, June 23-29

Articles about commissioning electrical and power systems, eco mode in UPS systems, dc power distribution alternatives, glazing systems, and NFPA 99 were Consulting-Specifying Engineer’s five most clicked articles from last week, June 23-29. Were you out last week? Miss something. You can catch up here.


1. Commissioning electrical and power systems

Essential/standby power equipment and system components are some of the most critical electrical systems to be commissioned in nonresidential buildings.

2. Using eco mode in UPS systems

Saving energy is the ultimate goal when implementing UPS eco mode.

3. Exploring dc power distribution alternatives

Engineers should know when and where the use of dc power distribution is appropriate, and when it is not. In applications where redundancy, immediate transfer capability, high availability, and energy storage are design criteria, direct current power solutions are beneficial.

4. Glazing systems: Considerations for the mechanical engineer

Window glazing and shading or louvers have a direct impact on the HVAC load of a building. Mechanical engineers often are tasked with specifying window and shading systems. Know about building envelope, and how it can be managed/altered by window system selection.

5. NFPA 99: Health care facilities code overview

Here’s a basic overview of the 2012 edition of NFPA 99, along with a review of the information covered in the new chapters.

The list was developed using CFE Media's web analytics for stories viewed on, June 23-29, for articles published within the last two months.
