The built environment offers us unlimited potential for a future of health and abundance. Sustainable design benefits the human community and natural ecosystems around us. It provides tools to create optimally resource efficient buildings, industrial facilities, utilities, airports, roads, and bridges.

Throughout our fifty plus years in the business, CHA has led the way with innovative green designs. From our early work on America’s Most Scenic Highways to our recent award-winning Smart Growth projects, we’ve helped set the standard that others follow today.

LEED® Professionals

Developed by the U.S. Green Building Council (USGC), LEED (Leadership in Energy and Environmental Design) is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings. Achieving LEED certification may qualify your project for certain tax rebates, zoning allowances, and other incentives.

CHA is a registered member of the U.S. Green Building Council and employs a staff of LEED Accredited Professionals, including landscape architects, engineers, and professional planners. From the initial planning stages to the achievement of certification, our experienced LEED® Accredited Professionals will be there to help set goals, guide progress, document construction practices, and interface with the U.S. Green Building Council.

Sustainability services

Smart Growth

We’ll energize your community with a plan for an appreciating tax base, new transportation options, walkable streets, and green spaces that will be around for our children’s children.

Energy Services

Our energy auditing and building commissioning professionals will help boost your energy efficiency and trim your costs. We can even help secure funding to make the recommended improvements.

Geothermal Heating and Cooling

With no fossil fuels burned, geothermal is one of the most efficient and reliable HVAC technologies available. CHA’s award winning designs earn LEED credits and can potentially help secure grant funding. We’ve designed systems from single heat pumps to applications for large commercial operations.

Wind Power Development

Wind power brings reliable energy with profound environmental and financial benefits. Our capabilities span the full project cycle, from wind resource analysis and wildlife habitat studies to full service design and construction.

Brownfield Redevelopment

We’ve helped many communities and private developers with creative brownfield redevelopment plans that are tailored to their unique economic goals.

Airport Sustainability

CHA helped pioneer a new model of aviation sustainability that takes an integrated and interrelated approach to design, construction management, and operations.

Green Infrastructure

By incorporating features like natural bio-retention areas, porous pavement, and vegetated swales to absorb rainfall, we can dramatically reduce stormwater runoff and the potential for combined sewer overflows.

Photovoltaic Systems

CHA supports companies that pursue renewable energy initiatives. Our project management expertise, efficient production methods, and fast-track project scheduling enables us to quickly and effectively plan, permit, design, and assist with the installation of PV systems.
