Two Case Studies in Centralized Vs. Decentralized Energy Approach

Centralized energy systems supply steam, chilled water and/or hot water to multiple buildings on a campus.  Decentralized energy systems supply utilities to a smaller group of buildings.  Key factors that need to be considered when determining if a centralized or decentralized energy approach should be used for a multi building campus are: Existing Building Systems. Existing Central Plant Equipment. Existing Campus Distribution. Campus Thermal Profile. Capital, Operating and Maintenance Costs. Future Campus Building Expansion Plans. Carbon and Energy Footprint. Life Cycle Cost Analysis. The presentation will present two case studies with a comparison of a centralized vs. decentralized energy approach.
