Another Look at Optimizing Pump Hydraulics

Pumps & Systems, Nov. 2016, by Lev Nelik.
http://www.pumpsandsystems.com/pumps/november-2016-another-look-optimizing-pump-hydraulics

"This column will provide feedback on a quiz published in my August 2016 Pumps & Systems column titled “Optimizing Pump Hydraulics: When Is It Important?” (Read it here) Readers were asked to estimate the amount of energy that would be saved by using a variable frequency drive (VFD) with a small centrifugal pump and to compare those savings to the energy used by a pump specifically designed for the required conditions (100 gallons per minute [gpm], 15 feet)."

Fan Selections and Their Energy Impacts, Part 2 of 2

HPAC Engineering, Oct. 2016, by Khalil Kairouz.

"Fans and fan systems can be significant consumers of energy in commercial applications and the greatest consumer in industrial ones. Concerned about underperformance, designers tend to compensate for uncertainties by adding capacity to fans. Oversizing fan systems creates problems that can increase costs and decrease reliability. This article explains how to evaluate fans and fan systems and their impact on operating costs."

Four Ways To Capture The Benefits Of Thermal Storage

Engineered Systems, Oct. 2016, by Khalil Kairouz, Vincent Priolo, and Safaa Al Musawi.

"In our world of growing concerns with global warming, utility companies across the world are making energy storage more cost effective for energy users. Initially, energy storage was developed to reduce the energy cost to the customer. However, there are many more issues which now benefit the utility companies, hence the rebate and incentive programs offered to get customers to implement energy storage."

Chiller Plant Optimization: The Role Of Controls

Engineered Systems, Oct. 2016, by Carlos Petty.

"Properly selected automated controls to minimize chiller plant energy, power consumption, and the cost of operations are essential for overarching chiller plant performance. Effective plant managers are driven to operate their plants at the lowest life cycle costs possible. This begins with the initial first cost of construction and recurring plant lifecycle operating costs, while still accounting for all the complexities and interaction among major plant equipment components."

Heat from Beneath the Ground – Working to Advance Deep Direct-Use Geothermal

U.S. Dept. of Energy, EERE, Nov. 15, 2016, by Timothy Patrick Reinhardt.

"Beneath our feet lies a source of geothermal heat that can be tapped to provide heating and cooling to both residential and commercial buildings, manufacturing processes, greenhouses and aquaculture ponds. Deep direct-use (DDU) systems are an emerging technology area in the geothermal sector that draw on lower temperature geothermal resources. Deeper than geothermal heat pumps and other conventional direct-use systems, DDU is deployable at a similar temperature range—between 100°F and 300°F—but at a much larger scale. DDU maximizes system efficiencies and return on investment."

Get Ready for New Federal Pump Efficiency Rules

Pumps & Systems, Oct. 2016, by Gary Wamsley.
http://www.pumpsandsystems.com/pumps/october-2016-get-ready-new-federal-pump-efficiency-rules

"The U.S. Department of Energy (DOE) earlier this year published a request to industry for assistance in developing new efficiency standards for pump systems. The federal notice (81 FR 5658) will lead to new federal regulations aimed at improving reliability and further reducing energy consumption nationwide in pumps, including circulator pumps."

The Internet of Things and Intelligent Facilities Management

HPAC Engineering, Nov. 7, 2016, Leroy Walden.

"The application of intelligent-building and IoT technology should support three important goals: reduce costs, reduce risk, and improve the occupant experience."

A Road Map for Optimized Maintenance

Flow Control, Nov. 1, 2016, by Michael J. Trainor.
http://www.flowcontrolnetwork.com/a-road-map-for-optimized-maintenance

"Unexpected failure of machinery is never a welcomed option for any plant, especially in the case of critical assets. Productivity may take a big hit when an asset goes down for emergency fixes. Could a developing problem have been detected earlier? Could the failure have been prevented or even predicted? An operation’s maintenance strategy — or lack of one — holds the key."

IIoT and the Smart Grid Connection

Automation World, Nov. 3, 2016, by David Greenfield.

"As different as the energy industry is from the manufacturing and processing industries, there are increasing connection points between the two when it comes to Internet of Things technology deployments and the benefits that can be derived from them."

ASHRAE Standard 90.4: First Look at Energy Standard for Data Centers

ASHRAE Journal, Oct. 2016, by Ron Jarnagin.
http://tinyurl.com/h9om44n

"Standard 90.4 is a code-intended energy standard designed to work in concert with Standard 90.1. In developing Standard 90.4, the basic structure matched that of Standard 90.1, which enables Standard 90.4 to simply refer to Standard 90.1 for requirements such as envelope, lighting and service water heating, which are within the scope of Standard 90.4 but are already well-covered by Standard 90.1. Standard 90.4 also references Standard 90.1 for mechanical equipment efficiencies, some of which are linked to U.S. Department of Energy legislation. So, if you are building or expanding a data center, you need to use both standards."
