Consulting-Specifying Engineer Top 5 most read articles online, for Oct. 20-26, covered selecting pumps and circulators, building energy modeling, ongoing commissioning and energy efficiency, commissioning giants, and lighting controls increasing energy performance. 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. 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. 

3. Ongoing commissioning ensures energy efficiency

Mechanical, electrical, plumbing, and fire protection systems must be engineered and commissioned so that the Dept. of Veterans Affairs has control over the system and so continuous measurement and verification are possible. 

4. Cx Giants make their mark

The 2014 Commissioning Giants had several new entries this year. The 15 firms reported a total of more than $351 million in revenue dedicated to commissioning new buildings or retro-commissioning existing buildings. 

5. Lighting controls increase energy performance

Engineers should look at the specific lighting control requirements in the latest versions of ASHRAE Standard 90.1 and IECC and review some best practices and insights on how incorporating lighting controls influences a building's energy performance.

The list was developed using CFE Media's web analytics for stories viewed on, October 20-26, for articles published within the last two months.
