OUR APPROACH
WHAT IS LEEDÂŽ?
CASE STUDIES
Ayers Saint Gross applies a high level of commitment to environmentally design all of our work. We are driven by the belief that high-quality built environments can be realized without depleting our natural resources. All of our projects endeavor to facilitate our clients mission, respect the history and context of the environments within which we work, and to provide a humanfriendly and efficient working and living space.
LEED stands for Leadership in Energy and Environmental Design and is a rating system developed by the United States Green Building Council (USGBC) to measure building sustainability. LEED promotes a sustainable approach in five key areas: Sustainable Sites, Water Efficiency, Energy Performance, Materials Selection, and Indoor Environmental Quality.
These case studies highlight the variety of sustainable design features used in each of Ayers Saint Gross’ LEED certified projects. They include general information about each job, credit category specific data, along with totals achieved in various key areas.

Most debris was diverted from landfills during construction and where possible project materials were locally sourced or included recycled content. Forest Stewardship Council certified wood was used for the majority of the project’s wood products.
WE: Water 3/5 The landscaping irrigation system uses only captured rainwater to minimize water use. Low-flow water closets, urinal, lavatory faucets, showers, and sinks decrease water use inside the buildings.
EA: Energy 4/17 To optimize energy performance, the project employs an improved thermal envelope, reduced interior lighting power density, and district heating and cooling strategies. The energy systems were commissioned to ensure compliance with the owner’s project requirements and refrigerants have been chosen to minimize contributions to ozone depletion and global warming.
IEQ: Indoor 8/15 Indoor air quality management began during construction. The installation of low-emitting adhesives, sealants, paints, coatings, and carpet systems means fewer VOCs will off-gas into the indoor environment during occupancy. The lighting system allows many occupants to adjust lighting to suit their individual needs and a thermal comfort survey was administered to ensure the building’s design provides appropriate temperature control to users.
ID: Innovation 4/5 The project earned exemplary performance for maximizing space, and achieved the pilot credit for walkable streets. In addition, the project team included a LEED Accredited Professional and the lighting design minimizes the need for mercury in lamps.
