ASHRAE’s new global headquarters demonstrates how an old, existing three-story building built in the 1970’s can be transformed into a high- performing, net-zero ready, multi-use facility in a cost-effective way that offers a framework for others to replicate. The 66,700 square foot office building was completely renovated and retrofitted using innovative technologies, systems, integrated design, and sustainable materials to reduce energy use, water consumption, and carbon footprint. The new building pursuing LEED and ILFI Net Zero certifications exceeds all of ASHRAE’s own energy and indoor environmental standards to achieve a high-performing and environmentally sustainable building with inviting spaces to work, adaptable educational places, and shared communal areas for gathering.
