sustainability

Langan services have always had a tendency toward sustainability.
Today, we proactively help clients and project stakeholders meet their triple bottom lines.

Langan is a leader in providing sustainable engineering services on urban infill, brownfield, and landfill development projects. These projects help clients and communities reuse impacted lands and combat urban sprawl by allowing communities to densify from within instead of expanding. The sustainability benefits to our communities are many – from reducing traffic, lowering reliance on cars, preserving undeveloped open space, reducing pollution and carbon emissions, and promoting health and quality of life. 

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 services.

Our diverse portfolio of intelligent site planning, design, and engineering coupled with our brownfield and site remediation expertise places us at the forefront of the sustainable design movement. Langan has been an instrumental player on hundreds of LEED and sustainable design projects.

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.
