Efficient Design Analysis for Research & Development Complex 'X'

This detailed analysis, conducted by Jim Gawthrop, explores options for redesigning the mechanical systems in a 5-building research and development complex in Baltimore/DC. The study focuses on reducing plant loads, centralizing utilities, and investigating combined heat and power strategies to optimize efficiency and sustainability. Key aspects such as initial costs, lifecycle expenses, indoor air quality, and environmental impacts are thoroughly evaluated to propose effective solutions. The integration of innovative technologies like underfloor air distribution, hydronic radiant ceiling panels, and active chilled beams is considered to enhance office airside operations. By scrutinizing power distribution strategies and their schedule impacts, this analysis aims to streamline operations and maintenance for long-term cost savings and operational efficiency. Overall, the goal is to provide recommendations that balance efficiency gains with practical implementation for the complex's mechanical systems.
