HVAC Design Intent:

  • The HVAC system selection and design intent is based on the processes outlined in ASHRAE Handbook 2020 chapter 1 HVAC System Analysis and Selection and include the following:
    • Owner project requirements (OPR): building program goals and additional goals
    • Incorporate the university’s deferred maintenance 10-year plan with the university’s new decarbonization and electrification master plan
    • Introduction of two solar panel fields, one wind farm, and a 50-megawatt battery storage facility
    • Expand the university’s building automation system (BAS) to include new system automatic controls to monitor utility electrical and fossil fuel consumption to benchmark data in the transition process to manage the utility costs, decarbonization, and electrification process monthly
    • Populating new equipment data into the existing computerized maintenance management software (CMMS) System to replace deferred maintenance equipment and systems
  • Program and Project Goals:
    • Budget Goals: Life cycle cost and electrical operating cost and electrical demand
    • Timeline Goals: Phased in decarbonization and electrification each year, spanning 10 years
    • Management Goals: Measure decarbonization through software and phase out deferred maintenance equipment powered by fossil fuel sources
    • Replacement existing HVAC systems with ground source heat pumps, waste heat recovery systems, etc.
  • Utility Availabilities: Electricity, BAS system, the fuel oil systems, and a natural gas distribution system
  • Existing Conditions:
    • Decentralized HVAC systems and fossil fuel support systems
    • Decentralized plumbing systems and associated fossil fuel support systems


  • The HVAC design criteria shall be in sync with the project delivery method and owner’s project requirements noted above
  • The HVAC design criteria, as well as the campus-wide systems design criteria and associated processes, e.g., shall be transitions to electrical systems in the next 10 years, phasing out fossil fuel generated systems campus-wide in sync with the project delivery method and owner’s project requirements noted above
  • Become electrically self-sufficient through the introduction of solar panels, windmills, and battery storage
  • The design criteria shall be based on ASHRAE 90.1 and state energy code compliance
  • The new automatic controls shall interface decarbonization and electrification software and DOE software tools with the existing BAS system
  • The existing central fossil fuel plant shall be phased out
  • With each new replaced mechanical systems, replacing fossil fuel powered systems shall include IPD Conceptual/Schematic Phase General Climate transition consultant and consulting engineers shall provide system flow diagrams with these three documents (OPR, DID, and BOD), along with sequences of phasing, operation, and maintenance
  • The existing university 10-year building program master plan shall be updated to incorporate the 10-Year Plan to phase out fossil fuel generated systems
  • The existing deferred maintenance master plan shall be updated with the removal of specific mechanical and electrical equipment and systems and replaced with new mechanical and electrical equipment systems
