Restoring The Low Limit For Indoor Relative Humidity

Engineered Systems, Feb. 2014, by Gary L. Berlin.
http://www.esmagazine.com/articles/96370-restoring-the-low-limit-for-indoor-relative-humidity

"Industry leaders realized hundreds of years ago that their processes and machines operate best when the indoor relative humidity is maintained at an optimum level for their process. They found it was necessary to use energy to increase productivity, lower scrap and environment impacts, maintain profits, and maintain costs to their customer. It does not matter if their process is related to food, woodworking, textiles, printing, pharmaceuticals, electronics, automotive, laboratories, or maintaining and preserving artifacts in museums and libraries. Controlling the indoor humidity was and is still critical for their applications."

"In its latest effort in an ongoing program to green its campus in South Portland, Southern Maine Community College (SMCC) turned to an innovative way to heat and cool one campus building: seawater.

Tapping into nearby Casco Bay, the seawater-based system uses a variable refrigerant flow (VRF) configuration with geothermal heat pumps to heat and cool the 3,250-sq-ft Lighthouse Building, which houses the school’s arts program and offices for The Foundation for Maine’s Community Colleges."

Is Your Building Conducive to the Installation of a Green Roof?

"Despite the potential, installing a green roof is not a decision to be taken lightly. There are several structural and site/location considerations to take into account. The most recent news of a probable green roof collapse at a Latvian supermarket should give one pause. Before allocating the time and resources, facility owners and managers should weigh the pros and cons of a green roof and what to keep in mind during the planning stages."

"Realizing the fundamental intent of commissioning requires an inherent understanding of a facility, the procedures/operations within, and the integration of building systems. This reaches far beyond documents and is where the value in commissioning is found."


VFD, Motor Strategies for Energy Efficiency

Consulting-Specifying Engineer, Jan./Feb. 2014, by John Yoon, PE, LEED AP.
http://www.csemag.com/single-article/vfd-motor-strategies-for-energy-efficiency/5d507c13fed1f2680da1f419b85cefa6.html

"A variable frequency drive (VFD) often is specified to save money by reducing energy consumption in pumps, fans, compressors, or any other motor loads that may be found in a typical building. These best practices will provide the engineer with information on how to specify a VFD to meet load conditions while achieving efficiency."

Don't Blow Your Money on a Steam Trap

"Steam and condensate leaks cost buildings and industrial plants millions of dollars in lost energy, while increasing emissions from boilers due to increased operation, creating potential safety hazards, and lowering the reliability of operations. This article will review the many factors that impact the reliability, performance, longevity, and maintenance requirements for condensate return piping systems."
