Consulting-Specifying Engineer’s top 5 most read articles online for Jun. 18-24 covered future-proofing a chilled-water system, VRF challenges, 40 Under 40, clean agent suppression systems, and NFPA 92. Link to each article below.

1. Future-proofing a chilled-water system

Chilled-water system design often focuses on the proper initial operation of the system. However, understanding—and planning for—changes that occur as the system ages is critical to designing a chilled-water system that will operate properly for years to come.

2. VRF: Overcoming challenges to achieve high efficiency

Variable refrigerant flow systems can result in effective, high-efficiency HVAC designs, but care must be taken to achieve proper ventilation, humidity control, and compliance with ASHRAE Standard 15.

3. 40 Under 40 winners shine

The 2018 40 Under 40 winners are full of knowledge, innovation, and exceptional dedication to buildings and engineering. 

4. Selecting the correct clean agent suppression system

Clean agent fire suppression systems are used to protect facilities with high value per volume. They work on a total flooding concept, causing quick extinguishment of a detected fire, limiting damage to the protected space and its contents.

5. NFPA 92 guides smoke control system design

NFPA 92 is the starting point for any smoke control system, but too frequently it is assumed to be the only standard by which to judge smoke control calculations.
