Articles about selecting pumps and circulators, mitigating arc flash hazards, active and passive fire protection, specifying passive firestop systems, and building energy modeling were Consulting-Specifying Engineer’s five most clicked articles from last week, October 27 to November 2. Were you out last week? Miss something? You can catch up here.


Consulting-Specifying Engineer Top 5 most read articles online, for Oct. 27 to Nov. 2, covered selecting pumps and circulators, mitigating arc flash hazards, active and passive fire protection, specifying passive firestop systems, and building energy modeling. Link to each article below.

1. Sizing, selecting pumps and circulators

By making correct pump and piping selections, a hydronic system can operate at or near peak efficiency, avoiding cavitation and vibration. Here's a look at relevant codes and best practices. 

2. Mitigating arc flash hazards

Engineers should know about selecting the appropriate risk-reducing strategies to help their clients ensure compliance with NEC, NFPA 70E, and OSHA. 

3. Balancing active and passive fire protection

Fire protection engineers can and should consider the building's construction, fire suppression systems, and smoke control when designing fire protection systems. 

4. Specifying passive firestop systems

Fire-rated wall assemblies and passive firestop systems are key elements to the design of all commercial buildings. 

5. Applying building energy modeling

Whole building energy modeling techniques and software are crucial for designing code-compliant buildings. At the same time, this near-mandatory exercise introduces opportunities for engineers to add significant value to projects.

The list was developed using CFE Media's web analytics for stories viewed on, October 27 to November 2, for articles published within the last two months.
