AGU headquarters rendering<\/p><\/div>\n

Is it possible for an urban office building renovation to achieve net zero energy? The American Geophysical Union is proving it is. Its overhauled 62,000-square-foot headquarters in the Dupont Circle neighborhood of Washington, D.C., is currently producing 3-5 percent more energy on site\u2014without using combustibles\u2014than it is requires.<\/p>\n

The cutting-edge redo was the topic of a session titled \u201cMission Zero: Scientists’ NZE Retrofit Fights Climate Change\u201d at the Greenbuild conference in Chicago. Chris McEntee, AGU\u2019s executive director & CEO, presented the project from the owner-occupant perspective. Yolanda Hickock, senior principal & owner of Hickock Cole Architects, represented the project\u2019s architecture & design firm. Roger Frechette, managing principal of Interface Engineering, discussed the sustainable strategies that his firm brought to the project.<\/p>\n

Built in the 1990s, AGU\u2019s iconic, triangular-shaped home base was no longer serving the society\u2019s needs. Many of the building systems were wearing out, the roof was leaking and its many closed-in offices reduced light and made the space out of date for today\u2019s working world. AGU wanted a building that was more collaborative and more reflective of their commitment to science, environment and humanity. And, in terms of sustainability, they wanted a building that would serve as a model for other projects that address the threat of climate change.<\/p>\n

\u201cIf we continue with business as usual, life is going to be pretty unpleasant for whatever life is left on the planet,\u201d said McEntee.<\/p>\n

Involving All Stakeholders<\/h2>\n

After deciding on a renovation versus a move, AGU gathered the designers, researchers and, even, policymakers into study groups to devise the ideal solution for AGU\u2019s constituents, the environment and the city.<\/p>\n

\u201cThat collaborative spirit has carried us throughout this,\u201d said McEntee.<\/p>\n

With a design in place, AGU moved out in February 2017. All the furniture and fixtures were removed from the building and were donated or refurbished to be used in the new space. (The toilets, for example, were used to create terrazzo wall tiles in the new space.)<\/p>\n

Hickok Cole\u2019s design included: Adding more windows to the exterior of the building to allow in more light and permit the building to be a showcase for the organization; creating a vertical link (staircase) in the center of the interior to allow for easy collaboration and easy movement throughout the building; installing more open work spaces with some smaller spaces for \u201cheads-down\u201d work; and creating a rooftop terrace with working and social spaces.<\/p>\n

\u201cThis is really about the people inside the building,\u201d said Hickok.<\/p>\n

Selecting Sustainable Systems<\/h2>\n

Frechette said that it was easier to find examples of sustainable renovations in more spacious areas than in cities where they are \u201ccritical.\u201d The team prioritized their search for the appropriate combination of sustainable strategies across four categories: first, reduction; second, reclamation; third, absorption; and, fourth, renewables. Among the sustainable systems Frechette\u2019s team settled on are:<\/p>\n

Solar photovoltaic array:<\/strong> The roof of the building was raised to accommodate an array of 696 solar PV panels, which produce all of the electricity needed in the building.<\/p>\n

Rainwater capture & reuse:<\/strong> A water reclamation cistern collects rainwater, filters it and chemically cleans it for all uses, except drinking water.<\/p>\n

Sewer heat exchange:<\/strong> The building is tapping into a sewer line and harnessing the energy for heating and cooling.<\/p>\n

Radiant ceiling system: <\/strong>The system saves energy and is quiet and comfortable, Frechette said.<\/p>\n

Green or wet wall:<\/strong> Air inside the building is circulated through the root systems of live plants where it is cleaned and filtered<\/p>\n

Direct Current (DC) power grid<\/strong>: Two-by-two DC electrified grids in the ceiling will eliminate the need to convert AC power into more efficient DC power. DC power will be generated by the solar PVA.<\/p>\n

After the presentation, McEntee received congratulations and a number of questions from the audience. Did the net zero commitment cost a lot more? That is always the assumption, McEntee said. But, considering AGU was looking at $20 million renovation regardless, the net zero strategies did not cost that much more.<\/p>\n

How can AGU be sure the building will be successful? McEntee reminded the group that AGU is an organization of scientists and\u2014succeed or fail\u2014this is an experiment. Therefore, the organization is keeping copious records and all research<\/a> and making it public. \u00a0\u201cWe are very hopeful, but we are not na\u00efve to think that something that we anticipated will go well might not,\u201d she said.<\/p>\n

Is the building LEED certified? McEntee said the building already has 96 points toward a LEED designation, but they are focused on performance rather than points right now. \u201cWe didn\u2019t want points to drive the design,\u201d she said.<\/p>\n

McEntee noted that AGU has already had interest in leasing the building\u2019s unoccupied space at above market rents. But they will only lease to tenants that buy into the building\u2019s mission.<\/p>\n","protected":false},"excerpt":{"rendered":"
