Were you out last week? Miss something? You can catch up here.


Consulting-Specifying Engineer's Top 5 most read articles online, for Jul. 4-10 covered 40 Under 40, noise and vibration control, combined heat and power systems, NFPA 99, and regulation of commercial, industrial fan efficiency. Link to each article below.

1. 40 Under 40

Consulting-Specifying Engineer magazine wants to shape the future of young engineers, and will do so by recognizing and encouraging them through mentoring articles in the magazine, young engineer networking events, and the 40 Under 40 program.

2. Noise and vibration control in building design

The acoustical environment in a building-good or bad-is the result of design. For optimal occupant comfort and facility functionality, attention to noise and vibration issues should be included early and throughout the building design and construction process.

3. Applying combined heat and power systems

Cogeneration systems, often referred to as combined heat and power (CHP) systems, generate both electricity and thermal energy. As they become more common in the United States, engineers must understand the nuances and design strategies for successful application.

4. NFPA 99: Electrical changes to the 2015 edition

NFPA 99: Health Care Facilities Code (2015 edition) covers a broad range of criteria for health care facilities. Electrical engineers need details about the changes to the electrical portion of the code.

5. Regulation of commercial, industrial fan efficiency

The new proposed Department of Energy standard will drive changes on how engineers design air systems for peak fan efficiency.

The list was developed using CFE Media's web analytics for stories viewed on, July 4-10, for articles published within the last two months.
