Northern Arizona University (NAU) Applied Research & Development

This project is ranked in the top one percent of all green buildings in the United States. The three-story $19 million 70,000-square-foot facility incorporates numerous earth-friendly design innovations, including fly ash in the concrete mix, which reduced the carbon footprint of the structure by 40 percent. At an elevation of 7,000 feet, this is the world’s greenest high-altitude building. The NAU research facility incorporated numerous environmentally responsible and sustainable design features. Schneider Structural Engineers introduced fly ash to the concrete mix, reducing the carbon footprint of the building by 40 percent. This innovative recycling of a by-product of coal burning also helps maintain temperature and reduce utility costs.
