Description

• Projects in this scope area may include: installing new central heating plants, ground or air source heat pumps, or high-efficiency gas boilers; decoupling of space and water heating systems; installing circulating, condensing, and other pumps, or fan coils for heat exchange; replacing distribution piping, valves, and traps; and replacing and/or removing apartment radiators. The full, detailed scope of work for this project including any additional work areas will be updated here after alignment with project stakeholders through scoping and design activities.

Baseline

• Hot water boilers that supply heat to the building through one- or two-pipe heating systems must have controls as mandated by regulating Codes. [COMPMOD]

Stretch

• Install new high-efficiency gas-fired condensing boilers. [COMPMOD]
  • Provide a preliminary cost estimate for hydronic conversion for steam systems where applicable.
  • Provide a preliminary cost estimate for decentralizing where applicable.
  • For sites that have recent or ongoing boiler replacement work, as identified in each development’s Modernization Report, teams can additionally price a scenario assuming retaining these existing boilers and give an estimate for remaining repairs-in-kind to other components of the existing heating system (assuming items and quantities identified in the PNA). If this option is pursued, teams should identify a path to electrification including a timeline. Highlight in your narrative response all costs associated with repairs-in-kind as well as costs associated with electrification-ready infrastructure anticipating future electrification. Include Remaining Useful Life estimates for all items to be repaired in kind.
• Assume one programmable thermostat in each unit. [COMPMOD]
