Figure 4. Portion of fuel-based heating apartment units using gas and oil. Cooling System Types Most multifamily building cooling systems do not use fuel-based systems for cooling. In this sense, cooling is already electrified. Unlike fuel-based heating systems, heat pump-based heating systems have cooling capabilities built in. A summary of cooling types for fuel-heated buildings is shown in Figure 5. In this chart, “Central A/C” is whole-apartment cooling via a split system with a condenser unit located outside. Figure 5. Cooling types in different climates. A substantial portion of buildings in the Marine climate do not have cooling of any type and may not need to consider adding one as part of a heat pump retrofit. However, most mixed-humid and cold climate buildings already have some type of cooling, which could be upgraded through a heat pump retrofit of the heating system. Steam or hot water heating systems have a separate cooling system, mostly room-by-room but a small amount of central cooling systems. Marine climates may not have a need for cooling equipment, relying instead on fresh air ventilation and a small number of window AC units where desired. Furnace heating systems may be combined heating/cooling systems with a condenser unit feeding the same ductwork in most cases, except perhaps in very cold climates where not much cooling is needed. Where there are room or unit heaters, such devices often provide cooling as well (as with PTACs). If room heaters do not include cooling, cooling may be provided separately by window ACs. Space Heating and Cooling Retrofit Strategies Each system type can move to be more centralized or less centralized (more distributed). The direction to take depends partly on the technical difficulty of the transition and partly on the desired level of control by occupants and/or building owners and staff. A centralized system is more dependent on the building owners and staff, Steven Winter Associates,Inc. 13PDF Image | HEAT PUMP RETROFIT STRATEGIES FOR MULTIFAMILY BUILDINGS
