Description

• Work scopes in this 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.

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]
