This case study explores the effects of retrofitting building systems on operational efficiency and employee productivity in the contemporary office environment. As concerns over sustainability and the well-being of employees are now at the forefront of modern workplace design, the retrofitting of outmoded building systems has been seen as an option to enhance energy efficiency and occupant satisfaction. This research paper focuses on the recently retrofitted Performance Contracting office building in Benicia, California. As heating and ventilation systems, and lighting are two big contributors to energy consumption in buildings and comfort, analyzing these systems provided insight into its building performance. This paper applies a qualitative and quantitative analysis looking at key metrics such as system performance, indoor air quality, and employee feedback on their productivity and comfort post-retrofit. Research findings indicated that the building retrofit improved employee efficiency, productivity, and comfort.
