Top 5 Consulting-Specifying Engineer articles, April 27 to May 4

Were you out last week? Miss something? Here are the Consulting-Specifying Engineer ’s five most-clicked articles from last week, April 27 to May 4, including articles about data center tier classifications, designing a sustainable sports venue, arc flash protection, preventing arc flash with codes and standards, and generators for data centers.


1. Data center tier classifications

Both ANSI (ANSI TIA-942 Standard) and the Uptime Institute have established tier classifications as guidelines for designing topologies that deliver data center availability and reliability. These resources further explain the differences between types of mission critical facilities. The following list explains the tier classifications:

2. Designing a winning sports venue: Sustainability

Sports and entertainment arenas are more than just seats and a playing field; they are highly complex structures bringing in thousands of fans—and millions of dollars—every year. Sustainability and energy efficiency are key factors.

3. Criteria for selecting arc flash protection techniques, Part 3

A variety of arc flash mitigation systems and active arc flash resistant switchgear are available to boost protection against arc flash incident energy.

4. How will you meet new code requirements for arc reduction?: Q&A Session

Arc flash incidents occur all too often and impact many lives. To address the problem in the industry, NEC 240.87 was developed to ensure arc flash safety in the electrical industry. Three industry experts weigh in through an extensive Q & A.

5. Generator ratings and the implications for data centers

Understanding how generator ratings are determined is quite simple, but there is a long list of variables to consider. This reviews the fundamentals of generator ratings and a recent industry discussion about specific ratings for generators in data centers.

The list was developed using CFE Media's web analytics for stories viewed on, April 27 to May 4, for articles published within the last two months.
