Sustaining Energy Efficiency
By JIM HANNA; Optimum Energy LLC; Seattle, Wash.

Although HVAC typically represents 40 percent of a commercial building's total energy use, energy efficiency historically has taken a back seat to occupant comfort in commercial-building HVAC design. With energy prices on the rise and commercial-building owners searching for ways to be more competitive, satisfy corporate social-responsibility objectives, and meet new government mandates, however, energy efficiency is becoming a greater and greater priority.

USGBC Releases Guidance for Multiple-Building LEED Certification

New guidance to help project teams get multiple projects at one site or campus certified under the Leadership in Energy and Environmental Design (LEED) Green Building Rating System is available. The "2010 Application Guide for Multiple Buildings and On-Campus Building Projects" was created to provide guidance when applying LEED rating systems to multiple-building and on-campus projects that are on a shared site under the control of a single entity, such as a commercial or educational campus or government installation.

USGBC Testifies on Capitol Hill

Sellen Sustainability, a U.S. Green Building Council (USGBC) member company, recently testified before Congress on the USGBC's behalf regarding the local business and community impacts of the federal government's investment in high-performance green buildings and other infrastructure. [More]

ASHRAE’s BEAP Recognizes Auditing and Analyzing Abilities

With the growing emphasis on energy-consumption reduction and cost savings, there is a recognized need for credible information to help in the assessment and modeling of building energy use. A new certification program from the American Society of Heating, Refrigerating and Air-Conditioning Engineering (ASHRAE) will help fill that need, recognizing individuals’ ability to audit and analyze residential, commercial, and industrial buildings. [More]

USGBC Opens Board Meeting to Membership

Each year, the U.S. Green Building Council Board of Directors invites members to attend a portion of the annual board meeting held in conjunction with Greenbuild. Any interested member may attend the meeting between 1 and 3:30 p.m. on Monday, Nov. 15, at the Art Institute of Chicago. [More]

Rooftop Units Reducing School’s Operating Costs, Environmental Impact
At Eagle Mountain Elementary School in Fort Worth, Texas, older HVAC units were noisy and not very energy-efficient. AAON provided 60 RQ Series (available from 2 to 6 tons) and six RN Series (available from 6 to 70 tons) geothermal-heat-pump rooftop units to Eagle Mountain Elementary School. [More]

Commercial-refrigeration-application motors
The Green Choice brand of motors is designed to address current environmental concerns. JuggerNaut, iMotor, and 3-in-1 motors are designed for commercial refrigeration applications and save energy by reducing the amount of electricity needed, resulting in thousands of dollars in energy savings for a typical supermarket.

Energy-usage meters
The Badger Meter Series 380 Btu meter is an all-in-one energy-usage package for monitoring hydronic heating or cooling systems. The units accurately measure flow and temperature differential to compute energy. They can measure cold-service fluid temperatures from -20 to 60°C and hot-service fluid temperatures from 4 to 125°C. [More]

Cooling-tower motor-and-drive system
Baldor has introduced new direct-drive technology for the cooling-tower industry that improves reliability, reduces maintenance, runs more quietly, and saves energy. By combining the technologies of the field-proven laminated-finned-frame RPM AC motor with a high-performance permanent-magnet salient pole rotor design, Baldor offers an energy-efficient, power-dense product that can directly replace the right-angle gearbox and jack-shaft installation in many conventional cooling towers.

Hotel Operator Upgrades to High-Efficiency Screw Compressor in Chiller
For commercial-property owners forever on the lookout for ways to reduce their utility bills, a major opportunity arises when it is time to replace old compressors in HVAC systems. When Harrison Property Group, the owner of 10 hotels, needed to replace an aging 60-ton reciprocating compressor in its chiller at the Holiday Inn in Ocean City, Md., it turned to BITZER. [More]

Split geothermal systems
Tranquility split geothermal systems include the Tranquility outdoor split unit (TTP) and the Tranquility air handler (TAH). When combined, the pair has one of the highest efficiency ratings of any geothermal system on the market. The TTP, which comes in 26-, 38-, 49-, and 64-mbh capacities, has a built-in expansion tank to ensure stable loop pressure and a pre-charged compressor section with back-seating service valves for quick installation.

Energy-saving centrifugal fans
Energy-efficient RadiCal centrifugal fans are defining new standards in the field of centrifugal ventilation and air-conditioning technology. The RadiCal's fan blades are designed with an aerodynamically optimized hybrid construction that reduces noise by 50 percent and consumes 50- percent less energy compared with AC fans. [More]

Demand-Controlled Exhaust System Eliminates Noise Problem, Saves Thousands
Soon after Park Potomac Place, a luxury high-rise condominium in Potomac, Md., opened, residents started to complain about noise from the kitchen hoods and ducts. During troubleshooting, the traditional constant-speed exhaust systems were found to be exhausting large volumes of conditioned air to the outdoors. [More]

Thermal-imaging cameras
FLIR i5/i7 thermal-imaging cameras can be used to quickly diagnose problems, improve efficiency, and ensure worker safety. Ergonomically lightweight, the cameras are heavyweight performers. [More]

Oil, acid, and moisture purger, an energy-saving product
The OAM Purger is designed to remove oil, acid, and moisture from a chiller's refrigerant charge. Oil buildup occurs in all centrifugal chillers. Oil invariably finds its way into the evaporator, where it mixes with refrigerant, degrading system efficiency and capacity. [More]
--Redi Controls Inc.

Air-to-water reversible heat pump
By using natural gas as the primary energy source, GAHP-AR Series air-to-water reversible heat pumps supply hot water up to 140°F or chilled water down to 37.4°F. The same unit is suitable for heating or cooling by reversing the absorption cycle, using the outside air for heat rejection in cooling mode and as a heat source in heating mode. [More]
