Applied Research and Development Building
The Applied Research and Development Building (ARD) showcases
the latest innovations in high-performance construction technology, energy-efficient
design, and use of renewable energy.
It earned 60 points out of a possible 69 to meet the highest
rating—Platinum—from the U.S. Green Building Council’s Leadership in Energy and Environmental Design
(LEED) system. It is the greenest building in Arizona and has the third-highest
LEED point total in the world.
Achieving LEED Platinum
- 90 percent of waste materials generated from building
construction were recycled instead of sent to the landfill.
- About 30 percent of the materials used came from
recycled products, including insulation made from recycled denim jeans.
- 57 percent of the materials used were produced,
manufactured, or harvested locally.
- Wood used in the building was harvested from a
certified renewable forest in Arizona.
- The building’s concrete contains 40 percent fly
ash (waste from coal-fired electric plants), keeping this material out of landfills
and reducing the need for cement, the manufacturing of which is a significant
source of greenhouse gas emissions.
Energy-efficient practices reduce energy needs by 60
- A 160-kilowatt photovoltaic system donated by
Arizona Public Service (APS) provides up to 20 percent of the electricity for
- A back-up heating system uses roof-mounted solar
- Unique “enthalpy wheels” installed in the
air-handling units extract heat from the exhaust air to pre-heat fresh air from
the outside, capturing heat from the building that otherwise would be lost.
- Sunlight provides more than 75 percent of the
lighting for occupied spaces.
- Light-harvesting technology adjusts office
lighting by reading the brightness of the room.
- Automated shade controls regulate solar gain to
keep building temperatures within a comfortable range.
Reduced building impact
- Landscaping is designed to collect and filter
- The living or “green” roof on the conference
unit is designed to insulate the building, reduce the “heat island” effect
typical of large roofs, and maintain a native vegetation cover that requires
little or no supplemental irrigation after initial establishment.
- Indigenous landscaping reduces irrigation
requirements by 50 percent.
- Reclaimed water replaces potable water for
landscaping irrigation and flushing toilets.
- Low-pressure faucets, waterless urinals, and
low-volume toilets reduce water needs by 60 percent.
