EcoPlusHome in Bathurst- GT, SE
Outstanding Energy Efficiency Project: Residential New Construction, EcoPlusHome (Bathurst) Put simply, the EcoPlusHome is the most energy efficient home on record with Efficiency NB’s New Homes Program. The home was built this year in Bathurst through the collaboration and partnership of a number of companies who were brought together by Axel Lerche of marketing firm Tight Lines Production Ltd. The goal with the EcoPlusHome was to create a smart home environment in which the occupants did not rely on fossil fuels for electricity and heating needs. The home was designed as a complete system which began with site selection and …
Geothermal Heat Pump & Fireplace Insert in Cornhill- GT
The family who enjoys this geothermal heating system decided to use renewable earth energy back in 1986. Their experience since then has proven the reliability and comfort afforded by geothermal heat pumps. When their original pump in required replacement in 2010, there was no question of whether they would install geothermal again or not. The performance of the geothermal heat pump in their home also led to the installation of a large geothermal heating system on their farm. …
Geothermal Heat Pump in Petitcodiac- GT
A testament to the quality and durability of heat pumps. This 20-year old open-loop geothermal heat pump has provided consistent heat without any major problems during its lifetime. Four employees enjoy the warm in-floor radiant (hydronic) heating throughout the heating season. The 297 m2 (3200 sq. ft.) floors are heated to 22.2 °C (72 °F) for most of the winter by water from a well, which is heated by surrounding rock beneath the surface, and then circulated through ten in-floor radiant heat loops, and discharged into another well. Although the store doors are opened and closed all day long, which allows for plenty of cold …
Geothermal, Solar Air, & Hot Water in Midgic- GT, SE
The benefits of installing renewable energy have always made sense to the owners of this home. The family of four has installed three different systems, and see renewable energy technology as a great way to save money. Having a large home, they reduce their electrical bills by harnessing renewable heat from the sun and earth. They would have also installed a wind turbine, except they would have needed two, and the cost was too high, so they decided to wait and see how their friend’s turbine worked. By the time they saw how well it worked, the demand and price …
Geothermal & Solar Hot Water in Edmundston- GT, SE
This apartment owner has decided that ground source heat pumps (GSHP) are an excellent investment, and the right environmental choice for lowering emissions. Since GSHPs work best in larger structures, such as this 26-unit, 2044 m2 (22000 sq. ft.) apartment complex, this building is ideally suited for such a system. Also, combined with the fact that this GSHP also integrates solar hot water (SHW), the system is very cost effective as a result, and easily meets all of the building’s heating and cooling needs throughout the year. …
Passive Solar Home with Geothermal Heat Pump in Kingston Peninsula- PS, GT
The owners wanted to build a home that would have low long-term costs, be comfortable, and modern. They decided to build a passive solar home because it met these criteria. They find the home to be very comfortable, and are happy with their choice. They also chose very energy efficient appliances, and used recycled or very durable materials where they could. For instance, they used HardiePlank siding on their building exterior, as it is very durable and shouldn’t have to be replaced as long as the owners occupy the building. …
Government Building seeking LEED certification in Rexton- GT, PS
This LEED (Leadership in Energy and Environmental Design) office complex has recently been completed and has yet to be evaluated and rated to the LEED standard Specifications. …
Geothermal Heat Pump in Loggieville- GT
The installer underestimated the size needed for this house and therefore it took much longer and cost more than initially estimated. Initially a 1.8 t (2 tons) heat pump was required, but in the end a 2.7 t (3 tons) was installed. Also, 2 horizontal loops (152 m (499′) each) in yard were planned, but more heat was needed so 2 vertical holes were later drilled (45 m (148′) each). Plastic piping with glycol was used for all 4 loops. The house (255 m2 (2743 sq. ft.), 2-storey) was previously heated with an oil furnace, therefore duct work already existed in house. The oil heat used to be inconsistent, …
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, …
5.4 t (6 ton) Geothermal in Saint John- GT
This house was originally built as a beach side cottage in 1905 on the west side of the City of Saint John. This project was a major conversion of an oil fired hot water boiler system to an in ground vertical heat pump of 5.4 t (6 ton) capacity. The owner researched and directed much of the work himself and called upon the best-known local and regional experts available to install the wells, piping and heat pump equipment. The heat pump is rated at 5.4 t (6 ton) and is at least twice the capacity required for a house of this size. A key …
