Top Consulting-Specifying Engineer Articles, August 2011

Most visited articles at during August 2011 included getting to know the new lighting code, using geothermal systems to obtain net zero, chiller plants in humid zones, engineering smart hospitals, and MEP project profiles from the 2011 MEP Giants.


August 2011’s leading Consulting-Specifying Engineer online stories include:

Know the newest lighting code - Justin Schultz and Michael Chow explain the new ANSI/ASHRAE/IESNA 90.1-2010 lighting and lighting control changes. Figure 5: Exterior lighting zones are shown. Defined zones allow for differentiation between building sites to allow more lighting in well-lit zones and less lighting in dim-lit zones. Courtesy: Dept. of Energy Building Energy Codes Program

Achieving net zero with geothermal systems - In order to meet the most stringent definition of a net zero building, a building must have net zero energy and water usage, and waste production; geothermal systems are one way to meet those Five condenser water pumps were installed with variable frequency drives for soft start and stop.

Using chiller plants in humid zones - In this article, using chiller plants in humid zones is discussed; including an example of dual chiller plants achieving energy efficiency for a federal office building in Washington, D.C. 

MEP Giants Project Profiles - As part of the 2011 program, MEP Giants submitted project profiles detailing the variety of projects across the globe, with 50 of the 100 responding, there’s quite a lot to see.

Smart hospital engineering - In Consulting-Specifying Engineer August, expert engineers offered advice on engineering hospital systems intelligently, from HVAC to fire/life safety.
