It wasn’t long ago that green building was held up because clients weren’t demanding it. That seems to have changed according to an American Institute of Architects survey.
The 2007 Autodesk/AIA Green Index, an annual survey, shows that green building has taken a firm hold on the industry and has captured the attention of both architects and their clients. The survey reports 70% of architects say client demand is the leading driver of green building and that the primary reason these owners and developers are demanding greener buildings is for reduced operating costs. Architects are responding by significantly increasing their use of sustainable elements such as high-efficiency HVAC systems, recycled building materials and using software to model energy usage.
Today’s Green Building Landscape
According to the Autodesk/AIA Green Index, less than half of architects were incorporating sustainable design practices into their projects five years ago. However, this number is quickly rising with 90% of architects expecting to incorporate some sustainable elements by 2012. When asked to cite a reason behind clients’ push toward green building, 64% of respondents cited the reduced operating costs that can be obtained through sustainable design as the cause.
"Buildings are the leading provider of greenhouse emissions, and in 2005 the AIA set a goal to reduce carbon emissions from buildings by 50% by 2010 and to achieve carbon neutrality by 2030," said AIA EVP/CEO Christine McEntee. "The results of the survey are encouraging, but there needs to be a greater sense of urgency to make sustainable design the norm in the profession. To that end, we will be releasing additional resources in 2008 to better educate both architects and clients on best practices and benefits of green buildings."
The survey also shows that architects are making significant strides to meet their client demand for green building. Working to develop their sustainable design skills, 88% of respondents have received training or continuing education focused on green building. This year’s Green Index also shows a significant increase in the practice of sustainable design since 2002. According to this year’s survey, the industry has seen a 25% increase in the number of architects utilizing high-efficiency HVAC systems in their projects over the past five years. Other areas of growth include the use of highly reflective roofing materials, which has jumped 18% since 2002, and the adoption of energy modeling and baseline analysis, which has seen a 17% increase in that same period.
Moving the Industry Forward
While almost 75% of Green Index respondents believe that the building industry is headed in the right direction regarding climate change, and 54% believe architects are responsible for developing and implementing solutions to this issue, the survey also shows that there is still significant opportunity for architects to deliver on green building practices. Although 50% of architects reported having clients inquire about green building on the majority of their projects, only 30% of architects actually implemented green building elements in their projects. In addition, only 10% of architects are currently measuring the carbon footprint of their projects.
When asked what green building efforts they expect to adopt in the next five years, over half the respondents said they will be using tools to enable the prediction and evaluation of the environmental impact and lifecycle of the building materials used in their projects, a 36% increase from today. 56% of respondents also stated that they will be using design software to evaluate and explore alternative building materials to maximize energy performance and minimize their environmental footprint.
