Consulting-Specifying Engineer Top 5 most read articles online, for Feb. 22-28, covered designing with NFPA 101-2015, lighting system design, updates to ASHRAE 90.1, motors, drives, and HVAC efficiency, and designs for pumping technologies. Link to each article below.

1. Designing with NFPA 101-2015

NFPA 101: Life Safety Code dictates a great deal for all building types, including egress, features of fire protection, sprinkler systems, alarms, emergency lighting, smoke barriers, and special hazard protection.

2. Lighting system design

Lighting designers must consider eight key factors when specifying lighting systems for nonresidential buildings. In addition to considering the type of lighting fixture (LED, fluorescent, etc.), they must also take into account daylighting, lighting controls, codes and standards, and other factors.

3. Updates to ASHRAE 90.1

An update of ASHRAE Standard 90.1 looks at building envelope, HVAC, plumbing, lighting, and elevators and escalators. The bulk of the article will focus on the 2013 edition, with a look at 2016 addenda that are already approved.

4. Motors, drives, and HVAC efficiency

Engineers must understand how the components in the HVAC systems they design use power and how they can be optimized without compromising traditional design values. Motors and drives are shown in relation to the design of HVAC systems.

5. Designs for pumping technologies

By making correct pump and piping selections, systems can operate at or near peak efficiency, avoid cavitation, and maintain a long service life. With each system type a multitude of options are available to a designer or engineer; but within these, the best option must be selected for a given application.

The list was developed using CFE Media's web analytics for stories viewed on, February 22-28, for articles published within the last two months.
