The objective of this project was to study the operational control strategies for mixed-mode buildings, with a focus on: 1) developing a framework for understanding issues that guide the decision-making process that informs mixed-mode buildings, and 2) identifying and documenting example control algorithms used in existing buildings. We examined buildings that use a combination of manual and automatic control of windows and mechanical system components and the indoor and/or outdoor environmental conditions used as inputs into their control algorithms.
