Air and Water Heat Pumps in Fredericton- GT, PS
An air-to-air heat pump (with electric element backup) was installed as part of the construction of this new home, in 2008. The owner proceeded to add a backup by using a water to refrigerant heat exchanger to improve the efficiency of the system. The addition draws water from their deep well, runs it through the heat pump and dumps the water into a shallow well, so as to recharge the aquifer, creating an open loop system. The water to refrigerant addition takes over for the air-to-air component when the temperature dips below 0 °C (32.0 °F). This temperature will be slowly raised, …
Passive Solar Home in Bristol- PS
This new, passive solar home is built with a South-Southwest orientation, which is best for collecting heat and light from the sun. This home has large, efficient windows (double pane, low e) gathering heat all day, which is trapped by this highly efficient house (lots of insulation and tight building envelope). This makes the home very comfortable, with it being hot inside on days of −30 °C (−22 °F) or lower. On cold days with no sun, a wood pellet stove provides backup heating. …
Passive Solar & Masonry Heater in Bocabec- BE, PS
A number of features have been added to the house to make it more efficient, such as the use of strapping (to reduce thermal bridging), putting insulation on the exterior of the concrete foundation (so as to maximize thermal mass), and lots of insulation in the walls and ceiling. The house is also somewhat submerged in a hill, so as to provide extra protection from the elements. Local materials were used for constructing the house, such as local harvested trees cut at a local, water powered mill. Bricks for the masonry heater came from Lewiston, Maine, the closest source for …
Passive Solar in St. Andrews- PS
A number of features have been added to the house to make it more efficient, such as the use of strapping (to reduce thermal bridging), insulating foil as a vapour barrier, and lots of insulation in the walls and ceiling. Local materials were used for constructing the house, and no trees were cut down in order to accommodate its construction. …
Passive Solar Sun Room in Saint John- PS
The passive solar sun porch is a main feature of the original design as a beach house. The solar face of the house is situated slightly west of true south. All the restoration work on the exterior of the house including the windows is being done using natural materials, replacing wood with wood, and the storm windows are being replaced with new wooden framed windows of the original design. …
Passive Solar Home with Air-to-Air Heat Pump in Fredericton- PS
This passive solar house is situated in a residential area and blends into the surrounding mixed forest environment being adjacent to a city woodlot. The high insulation levels of ICF (insulated concrete form) construction, R-30 to R-50, are key to the passive solar heating. The generating element of the passive solar heat is the 2-storey south wall of 80% glass made up of EnergyStar rated high performance windows with triple glazing. …
Solar Wall Hot Air Circulation in the City of Saint John- GT, PS
The solar wall is located on the south side of 1.4 hectare (3.5 acre), 11150 m2 (120000 sq. ft.) building which serves as the City of Saint John’s Transit Centre bus garage or bus barn. Along with several other energy saving and environmentally sustainable features this building has earned a LEED Silver standard and has received several environmental awards. …
Passive Solar System in Fredericton- PS
The incorporation of the solar system and components had the advantage of being installed during a complete renovation of the 2-storey sun porch. Recycled materials were used for all of these projects, including insulation, double paned glass, and copper sheet and piping. The thermal-siphoning air panel (TAP) solar unit is built into the sun porch wall, which has been further modified to maximize passive solar potential. The sun porch is well insulated, ventilated and has duct work that connects the two levels, and which also circulates extra heat into thermal mass (concrete and crushed rock) below the porch, helping regulate …
Passive Solar Home in St. Andrews- PS
This passive solar house is built in an almost rural setting within the town of St. Andrews with a view of Chamcook Harbour and Passamaquoddy Bay on the north and east side. The north to northwest side is sheltered by a grove of softwood trees. The solar face of the house is facing basically true south and is made up of 50% glass. The windows are EnergyStar rated high performance windows with double glazing. The floor surfaces are masonry heat sink absorbing materials, that store heat during the day, and release it during the night. The roof overhang is designed …
