Implementation of sustainable design practices is increasing, largely driven by client requests for green building, according to the 2008 Autodesk/AIA Green Index, released earlier this month.
Some two-thirds of the architects responding to the survey said client demand is the leading influence on their practice of green building, the report states. Architects said they believe that client interest in green building is mostly driven by the reduced operating costs associated with sustainable design.
Over the past twelve months, nearly half architects agree that clients are implementing green designs on more than half of their design projects.
When asked to rate the importance of a list of green design elements, architects placed high-efficiency HVAC systems high on the list.
"High-efficiency HVAC systems maintain the highest perceived importance among architects for the second consecutive year," the report found. Some 73%, "selected high-efficiency HVAC systems as one of the five most important techniques in the design of green buildings. Additionally, it was the first or second choice of 44% of architects."
