The facility will serve students, building operators, building energy auditors, and will be used to support the development of new business ventures in energy efficiency.The Consortium for Building Energy Innovation (CBEI)—formerly the Energy Efficient Buildings Hub—at Philadelphia’s Navy Yard, is a research initiative funded by the Department of Energy and led by Penn State University that seeks to reduce the energy usage of commercial buildings to 50% by 2020. KieranTimberlake, a Philadelphia-based firm located three miles from Navy Yard, was selected by Penn State to renovate a 1940’s Georgian-style brick building to be a living laboratory for advanced energy retrofit technology. Included in the brief was an addition to the building, which evolved into a new stand-alone building across the street on Lot 7R, which aptly became the name of the building. The new 7R building, literally tied to the ground with groundwater-sourced heat pumps, is also formally and tectonically organized around passive solar strategies. A number of daylighting studies drove a re-shape of the building. An initial four-story cube was introduced in Robert A.M. Stern and Associates’ masterplan for the site, but became a long linear east-west oriented low-lying building. This configuration maximizes daylighting while minimizing over-shadowing on the site, establishing a framework for campus growth. 7R is loaded with environmental features including a green roof, a gray water reuse system, integrated daylighting strategies, and geothermal wells. These environmental priorities influenced an approach to building envelope design that balances performance with overriding aesthetics and compositional goals. David Riz, a partner at KieranTimberlake, says the composition of the facade is integral to the siting of the building: “In a large number of our projects, we accentuate the orientation of our buildings with facade treatments.” Brick, chosen for its relationship to a historic Navy Yard context, is utilized as a ‘solar shade,’ opening and closing along the south facade to manage direct heat gain, while eliminating the need for mechanized shades. ‘Rips’ in the brick fabric reveal a transparent glazing system adorned with horizontal sun shade louvers. To the north, the building visually connects to adjacent League Island Park by maximizing glazing along an elevated second floor ‘tree-top’ interior walkway. Arguably the most significant feature of the building envelope is a twin-wall assembly of insulated translucent panels, seen prominently along the length of the north facade, allowing the architects to maximize the level of daylight. David Riz says the panels are notably used both performatively and compositionally, spanning 19’ tall from the plenum to the roof coping: “We wanted to create syncopation in the patterning. We were trying to get a dual read on a long linear building introducing key moments as your eye moves along the building.” The panels are incorporated into the west facade as a primary material to help manage a harsh late-afternoon sun in the large auditorium’s break out space. Riz celebrates the success of the facade in managing a difficult western orientation through diffusing harsh sunlight into a soft glow: “When you’re in the break out space, you simultaneously sense the daylight from the west, a view to the north park, and also a view through the flying brick screen to the south. That’s where it all comes together.” Riz considers the quality of daylight filtering through the building envelope to be one of the project’s greatest strengths: “There are very nice moments as you walk through the building because its so narrow where you experience a simultaneity of the south facade and the north facade: a hint of the brick screen through the classrooms, and bays of transparent panels to the other direction.” KieranTimberlake, who recently received an award for Innovative Research at ACADIA 2015, continues to monitor for thermal performance and storm water analysis. In this regard, the 7R building is a blend between high tech data monitoring, paired with low-tech passive strategies and off-the-shelf products. The project, completed within the last year, will be utilized by Penn State for various research programs.
A high-performance building prototype which shares energy with a natural-gas-powered hybrid electric vehicle.A cross-disciplinary team at Oak Ridge National Laboratory (ORNL) have designed an innovative single-room building module to demonstrate new manufacturing and building technology pathways. The research project, named Additive Manufacturing Integrated Energy (AMIE), leverages rapid innovation through additive manufacturing, commonly known as ‘3d printing,’ to connect a natural-gas-powered hybrid electric vehicle to a high-performance building designed to produce, consume, and store renewable energy. The vehicle and building were developed concurrently as part of the AMIE project. The goal of AMIE was twofold according to Dr. Roderick Jackson, Group Leader of Building Envelope Systems Research and Project Lead for the AMIE project at ORNL: “First, how do we integrate two separate strains of energy: buildings and vehicles; and secondly, how do we use additive manufacturing as a way to create a framework for rapid innovation while not becoming constrained by the resources of today?” Additive manufacturing contributed to formal expression of the building envelope structure and offered efficiencies in material usage while significantly reducing construction waste. Jackson says the design and manufacturing process became embedded into the ‘rapid innovation’ spirit of the project. “The architects at SOM worked hand in hand with the manufacturing process, sharing the building model with the 3d printers in the same way that the vehicle shares power with building. For example, within the course of less than a week, between the manufacturer, the material supplier, the 3d printers, and the architects, we were able to work together to reduce the print time by more than 40%.” In total, the AMIE project – from research, through design, manufacturing, and assembly – took 9 months. The building incorporates low-cost vacuum insulated panels into an additively manufactured shell, printed in 2’ widths in half ring profiles, assembled at Clayton Homes, the nation’s largest manufactured home builder. The vacuum insulated panels consist of Acrylonitrile butadiene styrene (ABS) with 20% carbon fiber reinforcement, a material which serves as a “starting point” for Jackson and his team: “We wanted to open up the door for people to say ‘what if?’ What if we used a non-traditional material to construct a building? I see this product as a ‘gateway.’ This might not be the final material we’ll end up using to construct buildings in the future. We’ll need to find locally available materials and utilize more cost-saving techniques. But we had to start somewhere. The ABS product will open the door for a conversation.” The project emerged out of fundamental questions concerning access to, and use of energy. Climate change, an increasing demand for renewable energy sources, and uncertainty in the balance of centralized versus distributed energy resources all impact the grid. In addition, more than 1.3 billion people worldwide have no access to an electric grid, and for an additional billion people, grid access is unreliable. AMIE will doubly function in the near future as an educational showcase to both the public who will learn of its story, and ORNL researchers who will continue to monitor how energy is generated, used, and stored. Will there be an AMIE 2.0? Jackson responds: “We don’t look at this as a one hit wonder. We really want this research to be the first stone thrown in the water that causes a ripple throughout the disciplines involved. Not only for us, but throughout the world. We want to put this out there so other smart people can look at it and brainstorm. If the end of the next project looks anything like AMIE 1.0, then we’ve missed the boat.”
In support of the historic effort underway to protect, improve, and restore the National Mall, the Department of Energy, in conjunction with the National Park Service, has decided to seek a new site for the U.S. Department of Energy Solar Decathlon 2011.And much to the chagrin of students, who have already substantially designed their buildings,the DOE hasn't yet named an alternative site. Students will soon be finalizing construction documents and building their houses for a fall exhibition, wherever that might be. One distraught student has created a petition to President Obama to reinstate the National Mall as this year's venue and over three thousand signatures have already been collected:
With only eight months remaining until the competition, we will face an insurmountable challenge to alter the designs, already in advanced stages, for installation in an as-yet unknown location. In addition, the considerable effort made to source materials and equipment for our solar-powered homes from local manufacturers and, in some cases, to engage the D.C. community in the afterlife of the structures may be for naught.There's also a Facebook page dedicated to keeping the Decathlon on the Mall, including email addresses for Secretary of Energy Steven Chu and Secretary of the Interior Ken Salazar. "We've been working on this project for over a year and a half," Reed Finlay, Project Manager of SCI-Arc and Caltech's entry, told AN's Sam Lubell. Their project, CHIP 2011, which includes a snug wrapping of vinyl over cellulose insulation, canted rooftop PV panels, and a sloping cantilever (previously) meant to highlight a view of the Washington Monument, has involved 60 students and over $100,000 in donations. "The Mall gives exposure and credibility to what we're doing... They don't know who they're messing with," he added. "I think they'll be surprised with the backlash."
