The US Department of Energy's (DOE) National Nuclear Security Administration (NNSA) ensures the nation's nuclear security. Comprised of eight science and manufacturing campuses covering 36 million square feet of facilities, NNSA is the heart of the US nuclear deterrence and non-proliferation missions. Its unique capabilities, from supercomputing to laser science, and workforce of upwards of 40,000, together consume 9.1 trillion BTU's per year. NNSA is challenged to invest in its workforce and specialized functions, while repairing and replacing old facilities--54% are over 40 years old. The newly expanded Asset Management Program (AMP), which on average is funded at $20-30M per year, uses a systems approach to invest in infrastructure to include roofs and cooling and heating equipment.By using an asset management approach, an organization can flexibly define and target performance goals, such as sustainability. The roof program, in place for more than a decade, has implemented a white roof, high insulation roof standard pre-dating several mandatory code dates. The cooling and heating program, currently in a pilot phase, drives sustainability throughout design. The differences between the systems have affected implementation of sustainability.Even with rigorous attention to sustainability, not all decisions are as sustainable as technically possible. Challenges to sustainability correspond closely with a triple bottom line model people/culture, economic costs/benefits, and sustainability performance. The roof and heating and cooling program have collected several lessons learned and best practices that could benefit others.
