Princeton University – Steam to Hot Water Conversion Group 3

Princeton University tasked Precis with the sizing and specification of systems required to convert existing steam heating and humidification systems to work with new campus low-temperature hot water distribution for the Shultz and Moffett Laboratory buildings and the Scully Hall dormitory. Precis worked with Princeton’s construction management partner under a design-build contract to generate conceptual designs, including architectural renderings and shadow analysis, and cost estimates for various rooftop and mechanical penthouse air-handling and heat-transfer system configurations and options that would accommodate construction phasing, future system expansion, redundancy, architectural screening, and maintenance access requirements.

The new systems include heat exchangers for low-temperature heating hot water and domestic hot water along with associated pumps, coil replacements, valence unit replacements, piping distribution, controls, and modifications to the existing steam systems. The design also required coordination of the project scope with a number of other ongoing projects in the Schultz and Moffett Laboratory buildings, including enabling work for the new Schmidt Hall building, an emergency/standby generator, and associated power system upgrade.
