Consulting-Specifying Engineer Top 5 most read articles online, for Mar. 2-8, covered driving data center design, optimizing genset sizing, VFD and motor strategies for energy efficiency, HVAC controls trends for 2015, and an alternative HVAC systems Q&A. Link to each article below.

1. Driving data center design

In the information age, data centers can be the beating heart of not just a building, but an entire global corporation. Engineers with experience working on data centers offer advice on their complex design and getting all the various aspects to compute. 

2. Optimizing genset sizing

When designing generator systems, consulting engineers must ensure that the generators and the building electrical systems they support are appropriate for the specific application. 

3. VFD, motor strategies for energy efficiency

A variable frequency drive (VFD) often is specified to reduce operational cost for pumps, fans, compressors, or any similar equipment with variable load profiles that may be found in a typical building. Here's how to specify a VFD to meet load conditions while achieving efficiency. 

4. Top HVAC controls trends for 2015

As the world becomes more concerned about carbon emissions and energy consumption, the overall efficiency of commercial buildings will remain a key area of focus. 

5. Alternative HVAC systems Q&A

Unaddressed questions from the Feb. 26, 2015, webcast on alternative heating/cooling systems include topics like variable refrigerant flow, energy modeling, and natural ventilation. 

The list was developed using CFE Media's web analytics for stories viewed on, March 2-8, for articles published within the last two months.
