U.S. architects call for more use of renewable energies in buildings

WASHINGTON, DC, US, January 11, 2006 (Refocus Weekly)

Architects in the United States want renewables to help reduce consumption of fossil fuels by 50% by 2010.

The American Institute of Architects (AIA) wants to promote sustainable design and resource conservation, with a goal of reducing current consumption level for fossil fuels for construction and operation of buildings by at least 50% by 2010. An adopted position statement commits to work with other groups, scientific researchers and public health officials to “develop and promote the integration of sustainability into the curriculum for the education of architects and architecture students, so that this core principle becomes a guiding mindset for current and future architects.”

“Buildings account for 48% of U.S. energy consumption and generate far more greenhouse gas emissions than any other sector,” says R.K. Stewart of AIA’s Sustainability Summit Task Force. “As architects, we must accept responsibility for our role in creating the built environment.”

“We feel it is incumbent upon the architecture profession to alter our actions and encourage both our clients and the entire design and construction industry to join us in plotting a course of measurable changes that will improve the quality of life for everyone,” he explains, and the AIA will support development of rating systems and standards which promote the “design and construction of communities and buildings that contribute to a more sustainable and environmentally conscious future.”

The undertaking will require a concentrated effort over the next 10 to 15 years, especially in educating clients about their role in the effort. “The time has come to require specific goals for significant reductions in energy use, with enhanced performance assured through commissioning of building systems.”

“To truly make an impact, there needs to be far greater use of renewable energy sources and the use of innovative design principles that will dramatically improve environmental performance in the built environment,” Stewart adds. “Because energy consumption reductions will be realized over the entire life of a building, we need to look beyond the first impacts associated with constructing a facility and really consider what happens over the many decades that the facility will be used.”

“The AIA recognizes a growing body of evidence that demonstrates current planning, design, construction and real estate practices contribute to patterns of resource consumption that seriously jeopardize the future of the earth’s population,” the statement explains. “Altering current practices of design and construction to realize significant reductions in the use of natural resources, non-renewable energy sources, and waste production and promote regeneration of natural resources will require a multiple-year effort in conjunction with clients, industry partners, and concerned organizations.”

The goal is to reduce current levels of fossil fuel consumption by at least 50% for new and renovated buildings by 2010, and to promote further reductions of remaining fossil fuel consumption by at least 10% in each of the following five years. As part of its support for rating systems and standards, the AIA wants such systems to require “specific goals for significant reductions in energy use, especially non-renewable energy sources, with enhanced performance assured through commissioning of building systems,” and to “promote the use of renewable energy sources.”

It wants the systems to require reduced use of non-renewable natural resources through the reuse of existing structures and materials, reductions in construction waste, promotion of recycled content materials, and use of materials independently certified as from sustainable sources, and to require specific goals for improved indoor environmental quality through enhanced indoor air quality, thermal comfort, acoustics, daylighting, and pollutant source control and use low emission materials and building system controls.

Standards should promote development and application of innovative designs to improve environmental performance, and recognize the lifecycle value of a project in addition to construction first costs, including assessment of impact on climate change. The data on lifecycle assessment should be used as the basis for design and construction decision making.
