Heating & Ventilation System
- Fresh air to each dwelling unit is supplied from a central, roof mounted, natural gas fired, warm air furnace.
- Outside air is drawn into the furnace where it is filtered and heated.
- A central duct from this furnace drops down through the building and spiders out horizontally on each floor.
- A branch duct from this spider network enters each dwelling unit and supplies air to a grille located near the entrance door.
- Within each dwelling unit a vertical hybrid heat pump circulates air to all rooms within the unit.
- The heat pump has within it a filter, fan, hot water heating coil and a refrigerant cooling coil with a water cooled compressor.
- The intent is that the fan runs at a low speed continuously to circulate air to all spaces. By doing this continuous circulation the fresh air that is provided near the entrance door is evenly distributed to all spaces.
- When there is a call for heating a zone valve within the heat pump opens and admits warm water to the heating coil. The water is not “hot” in the sense of normal heating water temperatures, it ranges in temperature from 100F to 120F.
- If the call for heating is not satisfied within 5 minutes the fan in the heat pump ramps up to a higher speed. By doing this the heating coil will provide more heat. It will remain at this higher speed until the thermostat is satisfied at which point it will slow down again.
- Hot water to supply the heating coil comes from the central boiler plant that provides all heating and domestic hot water requirements for the entire building.
- When there is a call for cooling a different valve in the heat pump opens and admits warm water to the heat pump compressor. The heat pump compressor is cooled by the “warm” water and in return produces refrigerant which provides cooling to the refrigerant coil.
- When the heat pump goes into the cooling mode the fan speed automatically increases to the high speed.
- When the cooling requirement is satisfied the fan slows down.
- A single loop of water circulates through the building and is connected to all heat pumps.
- The temperature of the water ranges from 90F to 120F. It is at the lower temperature during mild weather, spring and fall and at the higher temperature in winter and summer. The temperature is warmer in the summer because it is removing all of the air conditioning heat.
- When the loop temperature falls below the required temperature the central boiler plant will inject heat to raise the temperature.
- When the loop temperature rises above the desired temperature a “fluid cooler” located on the roof rejects heat to the atmosphere.
- Since the fluid cooler is located on the roof it is exposed to freezing conditions in the winter. For this reason there is a heat exchanger that isolates the fluid cooler from the inside water loop. The loop to the fluid cooler is filled with propylene glycol to prevent freezing.
- Corridors are supplied with outside air, heating and cooling from two roof mounted packaged air conditioning units.
- Washrooms within dwelling units are equipped with bathroom fans that exhaust directly to outdoors.
- Kitchen are equipped with microwave range hoods that exhaust directly to outdoors.
- Driers are exhausted directly to outdoors.
Alderney Landing Community Cultural Centre
Alderney Landing is a convention centre, art gallery, market, and theatre facility on the Dartmouth waterfront. It was opened in May, 1999. The theatre hosts many concerts, conventions and other events, and is also the home of the Eastern Front Theatre. The Craig Gallery provides an important opportunity for amateur and established artists to display their works. Painters, sculptors, and interactive multi-media artists have exhibited their works in the Gallery to date.
The following amenities can be found at Alderney Landing; art gallery, banquet seating, catering, event planning, fresh produce year round, meeting/convention space, Metro Transit ferry, Nova Scotia Liquor Commission store, outdoor eating area, outdoor stage, professional theatre, farmer’s market, seafood restaurant, meeting & seminar space, and a ticketpro box office.
