Project of the Year: Case Middle School, Punahou School
The Case Middle School complex was lauded for use of photovoltaic technology to generate electricity, a chilled-water plant to serve air conditioning needs, architectural elements of sustainable design, lighting efficiencies, and the creative use of recycled components in the building’s construction.
Innovation in Design (New Construction): Case Middle School, Punahou School
The combination of green design and conservation practices beyond energy use also earned the Case Middle School honors as the Innovation in Design winner for new construction, a new category this year.
Innovation in Design (Renovation): HMSA Building
The HMSA Building on Keeaumoku Street improved its HVAC (heating, ventilation and air-conditioning) system and installed advanced lighting which improved energy efficiency and safety while reducing maintenance time and expense.
Trade Ally of the Year: Energy Industries, Inc.
A new category this year, the Trade Ally of the Year recognizes exceptional leadership and commitment in the trade ally community. Honolulu-based Energy Industries provides energy consulting, project engineering and contracting services to hotels, business, schools and organizations to help them save energy, reduce their utility bills and take advantage of utility rebate programs such as HECO’s Energy$olutionssm for Business. From a one-person shop, Energy Industries has grown to nearly 200 employees assisting clients in Hawaii and around the globe to improve their energy efficiency.
Commercial (New Construction): The Honolulu Advertiser - Kapolei Production Facility
The Honolulu Advertiser installed numerous energy technologies including two, 275-ton centrifugal chillers, two cooling towers, a Variprime Package pumping system, three chilled water pumps, three condenser water pumps, variable frequency drive (VFD) controls for air distribution, and premium efficiency motors in the air handling units. Annual energy savings total $162,058 and the HECO rebate was $57,859.
Commercial (Renovation): Ohana Waikiki Malia Hotel
The 327-room hotel in Waikiki hotel replaced its three (60, 75 & 100-ton) chillers with two 160-ton high-efficiency water-cooled screw chillers; replaced condenser and chilled water pumps, added variable frequency drives on their premium efficiency motors, and also incorporated an energy management system. In addition to energy efficiency improvements, the hotel’s savvy financing strategy was recognized.
Institutional (New Construction): University of Hawaii, John A. Burns School of Medicine
The new University of Hawaii John A. Burns School of Medicine in Kaka’ako was designed to incorporate energy efficiency and state-of-the-art innovations in both its laboratories and office facilities. The complex encompasses 507,651 square feet built on 10 acres. Technological innovations include features such as a flywheel system, use of cold seawater in the cooling system, and light shelves. The 500 kilo volt ampere flywheel provides 15-20 seconds of power when there are brief electrical interruptions. This keeps power flowing to critical systems while emergency generators are activated. The facility’s annual energy savings total $230,000 and the HECO rebate was $213,756.
Institutional (Renovation): The Queen’s Medical Center
The 505-bed facility’s renovation project is noteworthy because it demonstrates that energy savings can be found by applying the latest advancements in technology to supplement a continuing program of energy vigilance. Many energy efficiency features already installed were upgraded to the take advantage of the latest technological improvements. Among the upgrades include window tinting to reduce heat gain, the latest generation T8 lamps and ballasts, occupancy sensors, and OccuSmart fixtures in stairwells. Other improvements were made to the cooling system and a new automation system was installed to detect malfunctions of building equipment and prevent energy waste.
Military (New Construction): Hickam Air Force Base C-17 Flight Squadron
Hickam installed dual-pane, low-e windows; a HVAC system with variable frequency drives; a new digital-controlled energy management system, high efficiency lighting and occupancy sensors to minimize energy consumption; and solar water heating that featured an array of 10 solar panels. Technological innovations include carbon dioxide sensors to control outside air in the conference facility and ultra violet heaters to clean chilled water coils and improve indoor air quality. The facility’s annual energy savings total $43,500.
Military (Renovation): Tripler Army Medical Center
The 229-bed, multi-service facility redesigned its chilled water loop operation and air distribution system, and installed a new digital control energy management system and heat pump system. The result of Tripler’s efforts can be seen in energy savings of more than $230,000 annually.
Residential: Kaanapali Shores by ResortQuest
Kaanapali Shores installed a high efficiency, variable flow chiller; redesigned the chilled water distribution header; replaced chilled water and condenser pumps with high efficiency pumps and premium efficiency motors; installed variable frequency drives on the cooling towers; and a direct digital control energy management system. Annual energy savings total: $156,740.
Small Business: Bougainville Flooring Super Store
Located in Salt Lake, the retailer and distributor of high-quality carpet and flooring earned the honor by upgrading their 200 T-12 fixtures with magnetic ballasts to newer T-8 Fluorescents with electronic ballasts. The key to this retrofit was the attention to lighting quality. By using the newer technology, Bougainville was able to improve the lighting quality in the store while reducing their electric bill. Energy consumption dropped by 10 percent and the company saves nearly $9,000 annually on their electric bill.
Multiple Facilities: Sheraton Hotels
Sheraton, already recognized by HECO for its energy efficiencies, continued improvements on their four Waikiki properties with the installation of variable frequency drives (VFDs), guest room energy management systems (EMS), and efficient lighting. Annual energy savings total: $513,484.
