UNIVERSITY OF PENNSYLVANIA GATEWAY COMPLEX PHILADELPHIA, PA

The need for increased chilled-water capacity to serve a growing campus prompted the University of Pennsylvania to plan a new facility in a highly visible location in West Philadelphia along the Schuylkill River at the University Avenue Bridge. The site, previously used for athletic fields, was one of the few remaining open spaces on campus large enough to accommodate the new structure. The design concept of the new Mod VII Chiller Plant encompasses both the building and site. A continuous perforated stainless steel screen wall in a fluid elliptical form wraps the chiller plant. The shape echoes the curves of the river and roads, and the material resonates with nearby industrial structures along the river. The perforated corrugated stainless steel screen veils the building, making it a shimmering, silvery object by day, and reveals the rooftop chillers above. By night, the building becomes a translucent glowing object, partially exposing the equipment within. PHASE I AND PHASE I-A The 60,000 SF footprint of the 30,000-ton chiller-plant equipment building and the specific shape and orientation of the baseball field required a combined building and site concept. The compact elliptical form adjusts to the curves of the river and roads with no distinct “face,” following along the site boundary to make room for the baseball field. By extending the screen enclosure beyond the boundaries of the plant itself, vehicle service areas are contained at the two ends of the structure and the plant inside can be built in phases. The two large elements are thus nested together within the constraints of the parcel to create an optimal setting for each. PHASE II With construction recently compeleted, the second phase of the project adds an additional 22,750 GSF and 10,000 tons of chilled water to the existing facility. The facility addition is entirely contained within the original metal screen wall from Phase I. Another 10,000 tons of chilled water equipment can be located within the building and on the roof in the future.

“Art and utility meet—a simple screening device transforms a utility plant into a major sculptural element in the landscape / cityscape / highwayscape, perfectly scaled for its location.” - Charlie Newman University Architect University of Pennsylvania

THE OHIO STATE UNIVERSITY EAST REGIONAL CHILLED WATER PLANT COLUMBUS, OH

This iconic new structure introduces a large, critically important infrastructure facility to a mature campus, preserves an important green space at the campus edge, and frames the gateway for a new campus entry. A sculptural solution for the 15,000 ton chilled water plant is integrated into the arts sculpture green area along the university’s east campus edge. The result is an elegant approach that fits well with the urban site and its surrounding context. The gem-like structure’s scale, which responds to the older brick buildings around it, is modulated by its composition of two offset volumes — a lower, two-story, glazed rectangular volume that is veiled and diaphanous on the exterior, with semi-transparent views from the interior looking out. The upper level; a lifted square volume, open to the sky, uses perforated metal walls of resin-based, coated aluminum to provide a cost-effective water cooling tower enclosure. The walls are designed with two perforated densities, and together with narrow open slots achieve the combined 50% open area for ventilation required for the equipment. The perforated copper-colored aluminum enclosure serves as a new interpretation of the brick used prolifically on this and many other US college campuses, adding aesthetic variety to its built surroundings. Designed to support the densely packed equipment layout, both the upper and lower volume respond to unique engineering requirements, creating zones of machine activity. A linear zone is created within the lower, two-story enclosed rectangular volume with mezzanine, and a squared zone within the upper screened volume. Both volumes are gently illuminated at night to provide site lighting for the surrounding pedestrian zones and to continue the dialogue between the forms and their contrasting materials. The glowing crystalline lower volume is illuminated from the inside. The repeating pattern of clear glass and translucent fritted glass in three frit densities and four sizes offers a consistent variability. The new LEED Certified chilled water plant will significantly improve overall campus central plant efficiency.

OHIO UNIVERSITY CHILLED WATER PLANT #3 ATHENS, OH

On a prominent site between campus and athletic fields, the new facility is located in an area highly visible to both the University and the community, and in proximity to mid-rise housing and recreation activities. The new chilled water plant provides up to 7,500 tons of chilled water capacity on the Ohio University campus, and importantly with immediate connection of student residences. It also provides the campus with electrical circuitry and switchgear for a new looped electric service and new feed point. The facility design provides an economical building aesthetic, and addresses environmental issues such as potential flooding, noise and plume factors. The plan building’s straightforward rectangular form and copper-colored insulated metal panel system blends with the neighborhood context in height, color and alignment. Two copper-colored colors and two textures of the metal panel system animate the exterior. Glass with opaque ceramic frit or clear glass on each elevation is inset to relieve the flatness of the panel system. The interior workspaces are thus all infused with natural light for workplace safety and well being. Roof-top perforated screening gives additional dimensional interest and proportional balance to the facility. For resiliency the main equipment floor is raised about nine feet above the floodplain; this also allows an efficient ventilation system for the main floor. A ramp provides vehicular access to the elevated main floor, and glazed bifold doors allow chiller maintenance and installation of future large equipment at the the main level. An effective acoustical sound wall with screened enclosure at the roof provides noise protection for nearby residential complexes, and rooftop cooling towers were selected to minimize plume issues.

UNIVERSITY OF MASSACHUSETTS NORTH CHILLER PLANT AMHERST, MA

The new North Chiller Plant is a new campus landmark, combining the university’s commitment to sustainability with an emphasis on increased student engagement. Located within the engineering quadrant of UMass, Amherst, the North Chiller Plant is a new campus landmark, combining the university’s commitment to sustainability with an emphasis on increased student engagement. The new North Chiller Plant and associated new campus distribution piping will increase chilled water capacity and support future expansion of the chilled water distribution system to serve additional campus buildings with an efficient loop system. A district energy network is a major contributor to campus sustainability goals since it combines the energy needs of many buildings, thus allowing an economy of scale that facilitates an investment in energy technologies that would not be feasible on an individual building basis. The North Chiller Plant building itself is currently tracking LEED Silver (USA, Sustainability rating.) The new North Chiller Plant replaces a smaller chilled water plant and enhances the Campus Master Plan by moving the energy plant out of a view corridor that extends from the center of campus out towards the Berkshire hills. Reconceiving the typical rectangular orientation of the chillers as an “angled parking” layout suggested the parallelogram footprint that makes maximum use of the narrow site beside the view corridor while continuing the campus grid layout. The geometry of the building further frames continuous pedestrian flows and views from the Engineering Lab building to the surrounding landscape. The parallelogram plan allows for optimum use of the space with vehicular access through 14-foot high bi-fold airplane hangar doors throughout the length of the building. The geometrical language of the building plan is also translated into the elevation. A continuous dynamic wrapper is constructed of energy-efficient insulated metal panels at the upper level that elegantly disguise the roofmounted cooling towers. Punctuated at the upper level with channel glass strips that illuminate the upper equipment platform, the silvery panels with their syncopated rhythm of joints float above a transparent base of curtain wall. The glazed base is highest on the north to allow vehicle access; the glazing head slopes along the east, south and west for reduced solar gain on those orientations. The transparent ground floor promotes the idea of “technology on display” by exhibiting the color-coded piping and equipment, thus transforming the building into an engaging visual learning element for the engineering community at UMass, Amherst.

PRINCETON UNIVERSITY CHILLED WATER PLANT EXPANSION PRINCETON, NJ

Princeton University required an expansion of their existing chilled water plant at a highly visible location along Elm Drive on the major vehicular entrance to the center of campus. The University also wished to include a large thermal energy storage tank in an appropriate setting. Our Chilled Water Plant Expansion and Thermal Energy Master Plan documented the proposed changes required to increase the physical plant’s capacity to service several new projects planned for the main campus in the next twenty years. A three phased plan of expansion was developed that would bring additional capacity on line incrementally. Elements included an eventual three new chillers within the plant expansion, an eventual ten to twelve new cooling towers, an eventual additional new chiller within the existing plant, and a large thermal energy storage tank. Siting was developed to consolidate required piping for the overall project and to minimize the impact of large new structures on the campus. The new chilled water plant connects to the existing plant and existing electrical mezzanine. The new plant uses the scope of the site to connect to grade at both the ground floor chiller equipment level and the office mezzanine. A new control room to service both the existing and new buildings has been constructed within the existing building and immediately adjacent to the new building to provide visual oversight from a single location. The new structure includes an upper floor to contain requisite pump and heat exchange equipment as well as electrical equipment. The new chiller plant building brings natural light into each equipment floor from both the north and the south sides through a system of translucent and fritted clear glass panels in a strong contrast to the long uninterrupted enclosure wall of local stone along Elm Drive. The building massing screens the rooftop cooling towers beyond and provides an aesthetically strong corner to the larger service precinct.

HARVARD UNIVERSITY DISTRICT ENERGY FACILITY BOSTON, MA

The new 56,000 sf District Energy Facility (DEF) sets the stage for a state-of-the-art, cost effective, and sustainable utility generation and distribution system for Harvard’s Allston campus that also makes a significant contribution to its urban design. The building’s compact cubic form with rounded corners allows for maximum flexibility of future development around it while maintaining a singular bold and refined presence. A wrapper of metal fins forms a screen around the facility, with petal-like elements set at varying degrees of openness to reveal or conceal the various equipment areas within. The exterior fins are most open at the structure’s corner entry and the round thermal energy storage tank, and most closed on its service sides. On the public face of the building, the fins are raised above the ground to reveal the main equipment hall to passersby. In addition to the many benefits of a district energy facility, the construction of the new DEF contributes to the design of infrastructure in the urban and campus form. Formerly relegated to the “backyard” of a campus with little visibility, today’s infrastructure plants are more centrally located to serve multiple buildings in a district and therefore face the pressures of relating in scale to nearby structures as well as mitigating noise and air quality. An innovative approach is required to celebrate their energy and robust beauty and to make them a good neighbor. The DEF was the first new building to be completed on the Allston campus, therefore carrying the responsibility of setting a high standard of quality and design as well as of creating a visible demonstration of sustainable practice in building, landscape, and storm water management. Flexibility and innovation were key goals for the design of the project, which provides chilled water, hot water, and electricity to the new campus. Resiliency is a key feature, with equipment elevated above flood levels, black-start cogeneration, and micro-grid integrations. A thermal energy storage tank supports efficient equipment use. The DEF began providing utilities to the new Science and Engineering Center in 2019, before its completion. The DEF’s site, at a pivotal location in the development area south of Western Avenue, makes the facility a highly visible presence from all sides. As a permanent support facility, its building and site design complements future campus evolution, including open space, academic buildings, and research and development spaces.

TUFTS UNIVERSITY CENTRAL ENERGY PLANT BOSTON, MA

Set into a dramatically sloping hillside at the edge of the campus, the new Central Energy Plant puts tri-generation energy efficiencies on display. The low ground form building integrates building and landscape to reduce the apparent mass of the large infrastructure installation in its prominent location. Two solid flanking walls of grey/beige brick emerge from the treed hillside and frame a transparent wall to the street revealing the chilled water, steam, hot water, and electrical power equipment within. On the downhill side, service vehicles have access to the building from the city street. On the uphill side, the campus driveway is at the elevation of the building roof which will be developed as a green space with spectacular views of the city and distant landscape below. Neighborhood concerns for sound pollution prompted careful attention to acoustical control. In addition to sound separation and attenuation within the plant, the upper part of the street façade is constructed as a metal panel acoustical baffle which reduces equipment sound, allows airflow to the rooftop cooling towers, and partially screens the equipment from view. Sustainable features include: •

A cogeneration plant, which provides 4 MWs of power, reduce energy costs for the Medford campus by approximately 20%. The university is taking a fresh approach to greenhouse emission analysis to be posted in the near future.

•

3 new high-efficiency steam boilers, capable of 50,000 to 90,000 lb/h will replace the less efficient boilers in the existing plant to be demolished.

•

Efficient chillers and cooling towers, 3,000 tons at full buildout, will provide air conditioning to the new Science and Engineering Complex, Tisch, and can be expanded to serve additional buildings in the future.

•

Increased reliability of the electrical power supply to the Medford campus.

•

Landscaping with native plants.

The location of the Campus Energy Plant in the campus Science and Technology Corridor facing a main city street maximizes the opportunity to convey the University’s commitment to sustainability to the city and the campus. Interpretive elements will highlight the energy savings features of the building and celebrate this important infrastructure element as a positive contribution to its environment.

MEDICAL CENTER COMPANY COMBINED HEAT & POWER PLANT CLEVELAND, OH

At a gateway location on campus, the highly-energyefficient / low-emission combined heat and power plant (CHP) is technically state-of-the-art and architecturally bold. The Medical Center Company (MCCo) is a not-for-profit shared district utility infrastructure that provides steam, chilled water and electricity to its member base including Case Western Reserve University, the University Hospitals of Cleveland Case Medical Center and others at reduced cost. The new plant will be constructed over the basement of an existing coal fired plant to provide connection to nearby cooling towers and an electrical substation. Consolidating the energy source to one primary supplier helps use fuel efficiently, saves money through economies of scale, allows for more effective equipment maintenance, and frees up space in each of the buildings that would have required separate heating and cooling supply sources. A district energy system optimizes the use of fuels, power and resources within the community, saving money and operating in a more environmentally friendly manner. Developing a new plant building of proper scale, proportion and material was the architectural design challenge for this project. As the entire MCCo site will be developed over two or more distinct phases, it is important to create a unified concept that facilitates future additions while retaining appropriate scale and site distribution. The site of the MCCo existing facility is quite prominent. Fronting on the corner of Adelbert Road and Circle Drive, the site is visible from the Cornell Road Bridge, Adelbert Bridge, the Murray Hill neighborhood, the nearby Case Western Reserve University recreational fields and more distant resident halls in the Murray Hill neighborhood. The site is also visible from the rail line and the RTA University Circle Station at Cedar Glen Parkway. Given the prominence of the site, and its position as a gateway to the campus, the architecture is educational and transparent. Capacity: Cogen - 15 to 30 MW initial 45 MW full build out. 65,000 lb/h of 150 PSI saturated steam capacity, Steam driven chiller at 2,700 tons

THE OHIO STATE UNIVERSITY ELECTRICAL SUBSTATION ENCLOSURE STUDY COLUMBUS, OH

This iconic new structure will visually shield a large electrical substation located at a newly developing area of campus near a busy public street, playing fields, parking and research development. A graphic solution for the approximately 16 feet high by 1700 feet long total enclosure is integrated into the green open space along Kelly Street. The enclosure is constructed with controlled rusting COR-TEN steel in a series of carefully developed patterns using solid plate, perforated plate, and 16’ long zones of vertical pipe. The result is an approach that animates the large enclosure. The material and patterns refer back to the long farming history of the site near the river. The new enclosure will be expanded from and initial 1500 feet to its final full length, phased to allow planned extension of the substation, a further 100 feet to the east.
