Consulting-Specifying Engineer Top 5 most read articles online, for May 11-17, covered the 2015 40 Under 40 winners, leveraging the BAS, CHW system design, lighting and HVAC integration, and webcast questions and answers on arc flash reduction. Link to each article below.

1. 2015 40 Under 40 Winners

Despite the diversity in their backgrounds and career paths, the 2015 40 Under 40 winners have many leadership attributes in common. 

2. Leveraging the BAS

By using the building automation system (BAS) to its fullest extent, a school district was able to control its HVAC, electrical, and lighting systems. 

3. CHW system design

Chilled water (CHW) systems are cooling systems that circulate CHW throughout a building for cooling and dehumidifying a building's air. They come in all shapes, sizes, and configurations. 

4. Integration: Lighting and HVAC systems

By considering the first principles of radiative energy, engineers can determine how to balance daylight, electric light, and HVAC systems, particularly considering various options for daylight control and the advent of LEDs. 

5. Your questions answered: Electrical Systems: Arc Flash Reduction and NEC 240.87 Requirements

James A. Smith, senior offer specialist at Schneider Electric, and Antony Parsons, PhD, PE, senior staff engineer at Schneider Electric, tackled unanswered questions from the May 6, 2015, webcast on arc flash reduction and NEC 240.87 requirements. 

The list was developed using CFE Media's web analytics for stories viewed on, May 11-17, for articles published within the last two months.
