When: November 9, 10:30AM to 1:30PM

Where: Glen’s Garden Market, 2001 S St NW, Washington DC 20009

  • 11-foot-6-inch high solar rooftop photovoltaic (PV) array to help generate on-site renewable energy
  • Municipal sewer heat exchange system to recover thermal energy from wastewater beneath Florida Avenue
  • Green wall to help reduce energy loads and improve indoor air quality
  • Water cistern to collect rainwater from the roof, as well as condensate water from the dedicated outdoor air system, to produce all the water needed for flushing low-flow toilets and irrigating on-site
  • Direct current (DC) electrified grid with DC LED lighting, which will allow the building to be more energy efficient and use power generated by the solar PV array 
  • A radiant cooling system that circulates chilled water through a network of pipes and uses less energy than a traditional forced-air system
  • Enhanced building envelope insulation, dynamic glass shading, and triple-pane glazing, among other interior and exterior high-performance strategies. 

     The project goes well beyond net-zero energy usage to include other sustainability elements by reusing unique architectural elements, 

     repurposing existing building materials, and offsite recycling of demolition and construction debris.

Roger Frechette, III PE, LEED AP, Managing Principal, Interface Engineering

 Roger’s impressive resume covers two decades of design experience, including sustainable/energy master planning and many significant iconic buildings. The Burj Khalifa, Dubai; Greenland Tower, Wuhan; Plot 16. Moscow; BBVA, Mexico City; and the Pearl River Tower, Guangzhou are just a sampling of his recent work. In 2004, he was recognized by the US Congress for his work in sustainability, and he is a current Senior Fellow with the Design Futures Council.

Cristine Gibney, Net Zero Energy Intern 

As a Master of Sustainable Design (MSSD) and Master of City and Regional Planning (MCRP) student, Ms. Gibney endeavors to make the planet a better place through sustainable practices in the built environment. She is interested in high performing buildings and passionate about exploring behavioral economics for post-occupancy follow-through.  Working with AGU on its headquarters renovation is providing valuable experience to allow her the opportunity to be a leader in the next generation of net-zero building implementation experts.

Matt Boyd, AGU Facilities Manager

Leading by example The American Geophysical Union (AGU) has renovated its existing 62,000-square-foot headquarters building to become the first-ever net-zero energy renovation of an existing commercial building in the District.  Net-zero is defined for this project as the total amount of energy used yearly by a building 
being equal to or less than the amount of energy created on-site through the use of innovative technologies and renewable power generation. Mr. Boyd is responsible for implementing AGU’s net-zero goals, implementing a variety of innovative geothermal, solar, HVAC, energy efficiency and green wall strategies and operate a flagship green building. 

Tour leaders:

AGU has renovated its existing 62,000-square-foot headquarters building to become the first-ever net-zero energy renovation of an existing commercial building in the District, and we are excited to invite you to join AEE for a tour of this facility on November 9th. Due to space limitations, we will be hosting registration & lunch nearby at Glen’s Garden Market (2001 S St NW, Washington DC 20009), so make sure to wear comfortable shoes and bring an umbrella if the weather doesn’t cooperate. We will be splitting the tour into two groups with one group starting with lunch and presentation at Glens Market while the other group tours the building.  Both groups begin by reporting to Glen’s.

AGU is an organization dedicated to advancing science and ensuring a sustainable future. Recognizing that the aging building and infrastructure would require a major renovation after 20 years of service, AGU seized upon an opportunity to lead by example. In addition to creating a welcoming and collaborative space for its members and the D.C. community that would facilitate the understanding of Earth and space science, the organization chose to design and engineer the modernization of the building to meet net zero goals. In so doing, AGU will be able to showcase real-world scientific advancement through innovative sustainable technology. Net- zero energy will be achieved through a variety of architectural, engineering, and advanced  technology methods which reduce, reclaim, absorb, or generate energy or water, including:
