Those small windows & no balconies seem like they could be concerning as far as being comfortable units to live in potentially(?). Just thinking of the heat island effect and during shoulder months (spring & autumn) when CAC isn't turned on, some units (in other buildings elsewhere at least) have reached ~80 to 85+F / 27 to 29C.
This would be true for those buildings configured with a two-pipe (supply and return) fan coil equipment heating and cooling system - which can only operate one way at a time, either heating for the entire building, or cooling, but not both at the same time.
Two other options are a four pipe (independent hot and cold water supply and return) fan coil system, or a heat pump based system. While the initial construction capital costs are greater, a four pipe system provides much greater flexibility for buildings (such as ours) which have either a cold side (long northern exposure facing), or would be subject to areas of increased solar gain in the winter. In such buildings, both the heating and cooling systems can operate year round.
The heat pump option involves a building wide water loop which is maintained at a constant temperature year round. The individual units have thermostat controlled heat pumps, which can either heat or cool the unit at the resident's choice, at any time of the year. When heating is required, the heat pump extracts heat from the water loop, heating the room. When cooling is required, the heat pump extracts heat from the air, and rejects it into the water loop. The main building heating / cooling system is used to maintain the constant year round temperature of the water loop.
The main disadvantages of the heat pump system would be that as part of the unit, it is the unit owners responsibility to maintain, repair or replace as required - they are far more expensive than a fan coil unit, and secondarily, they use far more electricity than fan coil units. So while maintenance fees would be reduced (not having to pay for the greater energy consumption of the building wide heating and cooling systems), the unit's electricity consumption costs would be increased over a comparable fan coil heated / cooled unit.
My guess would be that the Mirvish Village buildings may be using heat pumps, which if so would provide the necessary cooling capacity.
