9 kW and 500 W photovoltaic system in Mount Carleton- SE
Mount Carleton Provincial Park has relied upon propane and diesel fuel to provide power to its facility, as it is too far from the electricity grid. However, in recent years, the price of these fuels has been steadily rising, leading to increasing costs for the park. As a way to simultaneously reduce long-term energy costs and meet environmental sustainability goals, the Park has decided to invest in solar energy. …
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. …

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 …
Off Grid Carbon Neutral Living at Interpretative Centre in Heron Wood- BE, PS, SE
The Laforge Holstein plant is a biomass system set on 400 hectares (1000 acres) of land that uses organic materials such as potato peels, fries, pizza dough and tomato sauce, mixed with manure and chicken grease residue for biodigestion (anaerobic decomposition). The system has 2 mixing tanks that hold the organic material: tank 1 is used as an energy source and tank 2 is used as a protein source. These tanks are linked to the biodigester using a regular feeding schedule run by a computer program that is linked to all the machinery. The ideal pumping ratio of organic material or feed …
Solar Hot Water in Cape Jourimain- SE
In 2006, Cape Jourimain Nature Centre, at the foot of the Confederation Bridge, installed a 1.2 × 2.4 m (4 × 8′) solar panel (Thermo Dynamics Ltd.) to preheat some of the hot water needed for the restaurant. In order to reduce the amount of electricity used to heat water for the kitchen, a solar hot water panel pre-heats the water used in the kitchen whenever the sun shines. The system started operating in May, 2006, and we would need a few more panels to cover the entire hot water needs for the kitchen! A closed loop of glycol absorbs the heat from the sun, …
60 W Photovoltaic Panel at Cape Jourimain- SE
In 2006, Cape Jourimain Nature Centre, at the foot of the Confederation Bridge, installed a small photovoltaic panel to run the water pump for a demonstration water fountain. Cape Jourimain’s 60 W photovoltaic panel generates electricity when the sun is out. The current flows in one direction (like a battery) and thus the electricity generated is termed direct current (DC). There is no battery to store electricity. Even minor shading will cut the circuit and stop the pump from running. …
Geothermal in Cape Jourimain- GT
In 2001, Cape Jourimain Nature Centre, at the foot of the Confederation Bridge, installed a geothermal system to heat the buildings in the winter, and help cool them in summer. …
