The Environment & Green Buildings


The Environment

Irwin & Leighton is committed to protection of the environment and conservation of resources in all its activities. The Company implements and maintains environmental standards on all project sites in order to comply with the requirements of the Federal Environmental Protection Agency and their delegated regional or local compliance organizations. Further, many customers have stringent programs for prevention of damage to the environment during construction.

Irwin & Leighton maintains a Stormwater Pollution Prevention Program (SWPPP) that is administered by a corporate committee. The SWPPP accomplishes compliance through the implementation and maintenance of Best Management Practices (BMPs) in accordance with our procedures and programs and any customer-specific programs.

Green Buildings

Sustainability is an integral part of Irwin & Leighton’s business as building owners become more conscious of the positive effects efficient energy and environmental design can have on society as well as their bottom line.

Sustainability is measured by The Leadership in Energy and Environmental Design Green Building Rating System™ otherwise known as LEED. Buildings are rated by LEED standards established by the U.S. Green Building Council (USGBC) which defines LEED as “the nationally accepted benchmark for the design, construction, and operation of high performance green buildings. LEED gives building owners and operators the tools they need to have an immediate and measurable impact on their buildings’ performance. LEED promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality.”

Irwin & Leighton is a member of the USGBC and a sustaining member of the Delaware Valley Green Building Council.
