Port of Portland Headquarters & Parking 2 – Portland, Oregon

PDX HQ2P2

This project consists of a long-term parking garage with a new Port of Portland headquarters on top filling 205,000 square feet; the building has many green features and was designed to meet LEED, gold certification standards.

The facility uses 75 percent less water and 36 percent less energy . Underneath the building, more than 200 pipes provide ground source heating and cooling in a closed loop system, serving the passive radiant ceiling panel heating and cooling inside. This is the first coupling of these heating and cooling systems in the United States.

HVAC System & Efficiency:

The heart of the HVAC system features Multistack heat recovery chillers. The chillers are ground coupled via a closed loop system, and provide 100% of the heating and cooling needs of the facility, without the need for boilers or towers. The benefit of using Multistack for heat recovery is their ability to provide simultaneous heating and cooling at all load conditions. The chillers feature modulating valves for variable flow on both the chilled water and hot water loops, providing additional energy savings.

In addition, the job includes 10 Haakon custom air handlers to provide conditioned ventilation air and filtration, Team Air units for the data center, and 42 Trane fan coil units for individual zone controls.

Providence Health System, Newberg, Oregon

Award: LEED® Gold Rating—the first for a hospital on the west coast

The Building: Providence Newberg Medical Center,175,500 square feet

Scope of Work: A Trane Tracer Summit system was fully integrated with the hospital and office building for improving air quality, and monitoring the hospital’s isolation room pressure control system and medical gas systems via a Lonworks interface. Tracer Summit provides extensive energy use documentation, which was necessary to achieve the LEED Gold rating.

The HVAC System: Two Trane, CenTraVac chillers, variable-flow chilled water system, eight Haakon custom air-handling units, and more than 300 Trane air-terminal units. Providence Newberg Case Study

Wieden + Kennedy, Portland, OregonWieden + Kennedy

The Building: Six-story office, 185,000 square feet (loft style). Remodeled from a cold storage warehouse. The overall feeling of the building is a bright, natural and comfortable place for creative thought and efficient administration.

The HVAC System: Trane Tracer Summit Integrated Comfort System comprised of six Trane

Signature Series water-cooled, self-contained units provide heating, ventilation and air conditioning. A cooling tower on the building roof provides heat rejection for the water-cooled units.

Efficiency: The interior of three of the floors uses a low-pressure, under-floor air distribution system (UAD). Conditioned air is provided to a raised floor plenum at around 65 degrees and occupants adjust their personal diffusers for comfort as needed. When tenant improvement changes are needed, the building manager is able to perform the relocation of wall panels, electrical, communication and HVAC distribution in a matter of hours. As the system has extremely low static pressures, less fan energy is consumed. The cost premium for the raised floor was justified by the elimination of a drop ceiling, ductwork savings, and control savings from fewer automatic controlled zones. Wieden & Kennedy Case Study

American Honda Motor Company, Portland, OregonAmerican Honda

Award: LEED® Gold Rating—the first mixed-use industrial building in the country to achieve this rating

The Building: The American Honda Northwest Regional Facility totals 218,000 square feet, which includes an office, common area, training center and a warehouse. The training and warehouse areas are high-bay, single-story design, and the office and common area are single-story.

The HVAC System: Air is supplied to this area through a Trane T-Series Climate Changer unit that features precise ventilation control and complete mixing of conditioned air. Three rooftop air handlers receive chilled water from a single Trane 80-ton Series R Model RTWA helical-rotary chiller. The entire facility is controlled by a Trane Tracer Summit System, with NIST-traceable sensors and 1,400 data collection points.

Efficiency: Extensive commitment to energy efficiency and to environmentally sensitive engineering. Warehouse has 120 skylights and reflective white insulation on walls to maximize the use of

daylight. In the warehouse minimal energy input is needed for heating or cooling because of the high level of building insulation. American Honda Case Study

Fox Tower, Portland, OregonFox Tower

The Building: 29-floor high-rise office building with retail and cinemas

Scope of Work: Cooling is handled by two high-efficiency Trane Centrifugal chillers, with an additional 100-ton rotary chiller used for swing loads. Trane’s high-efficiency water-source heat pumps are used for the retail levels and cinemas.

The HVAC System: This EarthWise design has a built-up air handler that delivers 42 degrees F, leaving air temperature to the Trane series fan-powered VAV boxes. Trane Tracer Summit controls the system with a BACnet(TM) interface to the fire/life/safety system.

Efficiency: The EarthWise design allowed the mechanical engineer to reduce the size of the supply duct to accommodate a lower-than-standard floor-to-floor height, resulting in substantial savings in overall construction costs. Fox Tower Case Study

Grants Pass High School, Grants Pass, OregonGrants Pass High School

The Building: This project was modeled after a college campus to support a strong sense of educational excellence and tradition. The campus is joined by large open plazas that link nine buildings and provides a visual connection between facilities. Its 260,000 square-feet is spread over 30 acres and accommodates 1,500 students.

The HVAC System: Combined, the buildings consist of 23 IntelliPak units (50, 70, 25, 30 and 60 tons), 8 Voyagers (20, 17 and 5 tons), Trane VAV boxes, Varitrac and force flow heaters. The building controls are Tracer Summit System.

Three Rivers Community Hospital, Grants Pass, Oregon

The Building: Three-story hospital building, 206,000 square feet. Includes 98 inpatient beds, 6 operating rooms, nuclear medicine department, light-speed x-ray facility, MRI and CAT scan capabilities. Also includes a 300-foot-long, two-story lobby with registration, gift shop and coffee shop.

Scope of Work: Design-build partner in the development through commissioning of a complete mechanical system. TraneOregon produced an entire mechanical system by working with the owner, general contractor, and consulting engineer through the building cycle—from pre-design to commissioning and building occupation.

The HVAC System: Trane Tracer Summit Integrated Comfort SystemTM comprised of two 650-ton CentraVacTM centrifugal chillers, four Haakon custom air-handling units, Trane VariTrane VAV boxes, a Systecon wire-to-waterTM packaged primary, secondary, and condenser water pumping system, and complete integrated controls with advanced energy-saving optimizer software.

Wells Fargo, Portland, OregonWells Fargo

The Building: 39-story high-rise office building and bank.

Scope of Work: The purpose of the project was to replace existing 30-year-old Trane chillers. The challenges were that the existing chillers are on the 39th floor, and the building has no air-side economizers. Since the new chillers could not be brought up through the building, a crane was built on the roof. Although the change-out was required due to the condition of the existing machines, the job was designed to save a significant amount of energy. It incorporates an RTHC chiller and two CenTraVacs.

The HVAC System: The RTHC chiller is piped into the return water line so it can serve as the base chiller and is used for heat recovery. The two centrifugals are piped in parallel and have VFDs to reduce energy consumption at part load. All air handlers are retrofitted with two-way, pressure independent Delta P control valves to avoid a “low delta T” situation with the chillers. VFDs have also been added to the air handlers. All new controls were part of the retrofit.

Efficiency: The EarthWise design allowed the mechanical engineer to reduce the size of the supply duct to accommodate a lower-than-standard floor-to-floor height, resulting in substantial savings in overall construction costs. Wells Fargo Case Study
