Washington, DC

Located in the heart of downtown, the Washington, DC Design Studio serves the nation’s capital as well as the Eastern United States. The local team regularly  incorporates state-of-the-art design features to reduce energy usage in projects across the US.

The office holds a LEED Gold rating and uses 43% less lighting energy than a typical US office building of its size. The team is committed to recycling and fitness and encourages long walks and using the fitness center available during the lunch hour. Many gather together for lunch and with the District of Columbia close by, there is always a grand variety of things to do after work and on the weekends.

  • Managing Principal, Washington, DC

    Sara’s extensive project management expertise is demonstrated through her dedication to clients and her ability to manage at all levels of complexity. She builds a strong relationship with each client that she works with to not only makes the project more enjoyable, but it is also an essential part of ensuring a project’s success. Her electrical engineering expertise ensures that power systems are precisely designed and properly constructed in the field. Sara’s design focus is to incorporate sustainability into every project, from daylighting strategies to the design of photovoltaic systems for on-site power generation. Her background in lighting design allows her to apply the highest aesthetic standards, so that the lighting reflect the building’s character to enhance it, not overpower it.

  • Principal, Washington, DC

    Bill has been a passionate advocate for climate, green building and environmental policy for decades, and is recognized as a national leader in green building, urban sustainable development and climate planning and programs. Bill has a diverse career background—including spearheading green building and climate policy for the District of Columbia government, project management for a renewable energy company, construction management for a deep green design/build firm, sales for a green building supply company, and, in the early part of his career, environmental journalism for two national magazines. This uniquely varied background has allowed Bill to gain expertise in sustainability and climate planning, programs, and policy development, green building strategies and solutions, and renewable energy deployment. Having worked in all sectors—private, government and non-profit—he understands the challenges of budgets, time limitations, and the need for effective and efficient project delivery.

    Bill’s extensive work on green building, energy, and climate mitigation and adaptation has earned him multiple awards including a Living Building Challenge Hero Award (from the International Living Future Institute) and a BOLD Award at Greenbuild in 2015. Bill has substantial technical knowledge in green building, climate change, and neighborhood-scale sustainable development, but also thrives on the softer skills of project management, visionary big picture thinking, writing, and public outreach and communication. He uses this suite of skills to translate technical knowledge and information into plans and policies that citizens can understand and use to promote the greater well-being of people and our planet.
