Redesign and Analysis of Mechanical Options at Research & Development Complex “X”

This report outlines the mechanical options and redesign analyses for the Research & Development Complex "X", located in the Baltimore/DC area. The facility, which includes five buildings covering 1.5 million square feet, is focused on innovative office and laboratory spaces. The analysis covers mechanical systems such as VAV setups, underfloor air distribution, and a central utility plant featuring combined heat and power systems. The potential impacts on costs, lifecycle, indoor air quality, and environmental factors are discussed, along with strategies for optimizing energy efficiency and operational schedules.
