Before it was a buzzword, Langan was already leading the way in sustainable design.  Today, we proactively help clients, projects, and communities meet their triple bottom line.

We continue to push the envelope, promoting new approaches and sustainable design services, including:

  • Integrating bicycle and pedestrian infrastructure into greener, more Complete Streets
  • Designing innovative green stormwater management practices
  • LEED green building design
  • Wetland design and mitigation
  • Brownfield redevelopment and sustainable remediation

With over 100 Leadership in Energy and Environmental Design Accredited Professionals (LEED APs and GAs) and ENVISION Sustainability Professionals on staff, sustainable design weaves through all Langan experiences.

Our expertise allows us to make significant contributions in developing sustainable sites with an emphasis on stormwater management, low impact landscapes, brownfield redevelopment, materials recycling, energy conservation, and renewable energy design.
