Decarbonization Site Audits

Precis performed a decarbonization study of four of the client’s 15 highest carbon-generating sites. These sites consisted of pharmaceutical manufacturing, laboratories, warehouses, offices, and central utility plants comprising of over 3.1 million sf of occupiable space.

Precis performed detailed energy analyses to help the company achieve its decarbonization goals, with measures specifically tailored for decarbonization including renewable energy generation, electrification, and thermal energy/battery storage. Precis evaluated all energy-consuming systems at each facility including water-cooled HVAC chilled water systems; process chilled water systems; high- and low-pressure steam boiler systems; central cogeneration facility; air-handling systems for manufacturing, laboratory, and office spaces; exhaust systems; clean utilities including water for injection (WFI) and clean steam; compressed air; and lighting.

Precis identified over 375 viable opportunities across the four campuses with annual cost savings opportunities across all facilities totaling over $4.4 million. This resulted in a nearly 40 percent carbon reduction at the sites with the greatest opportunity. Strategic recommendations were made at each site to eliminate Scope 1 emissions in their entirety. Detailed energy savings calculations, cost estimates, payback analysis, and narrative to support a business case for implementing over 103 projects were also provided. Following the study, the client engaged Precis for the design of several opportunities relating to cogeneration feasibility, chilled water optimization, and boiler replacement.
