Sarah Widder joined PNNL in 2009. She focuses on sustainable design, energy efficiency, and green house gas management work. Specifically, she concentrates on the application of technology, standards, and regulation to meet these goals.

Ms. Widder is currently involved in using whole building performance metrics to analyze the impact and effectiveness of current sustainable design trends. Sarah is also involved in helping interested parties meet energy and carbon management goals by recommending design and operation solutions that conserve energy, water, and carbon on both an individual building and general building type level and creating federal standards to encourage the use of new energy efficient technologies.

Before joining PNNL Sarah's research interests included the effect of stove and fuel type on indoor air quality in rural China, the anthropological effects of scientific research on rural communities, and some geological survey work. She also participated in an internship program in Washington DC writing policy recommendations concerning nuclear waste management and researching the economic and technical metric of reprocessing and recycling spent nuclear fuel.
