NextEnergy's national headquarters is located in Elmira, Ontario and is a showpiece of the use of geothermal technology.
Our headquarters,located in Elmira, Ontario, is a showpiece of the power of geothermal technology.
Our headquarters combines energy efficient construction with geothermal technology and renewable electricity to create an inspiring "green building". We produce ZERO greenhouse gas emissions and still maintain an indoor environment that is the ultimate in comfort.
Our building operates so efficiently that even with the incremental capital costs of the geothermal system, which includes efficiency upgrades and wind-generated electricity, we still have a lower life-cycle cost than other buildings with conventional systems.
Information gathered from the operation of our building helps us with the design and implementation of creating holistic buildings. Our findings will help make wind/geothermal energy hybrid buildings less expensive on the first day of occupancy than any building using a conventional source of energy. These buildings will produce very low and predictable increases in energy costs, which provide owners with a "renewable energy insurance policy" against increasing energy bills and future fuel concerns.
- The floor is a cooling sink for office cooling loads.
- 50% of all energy used in domestic hot water production is recycled.
- De-superheaters and on-demand geothermal from NextEnergy heat pumps supply the majority of the domestic hot water used.
- Large 50' X 6' skylight and translucent loading dock doors allow sunlight in to help warm the building and reduce the need for artificial light during the day.
- On-site "Weather Station" collects weather data in real time to facilitate an on-demand heat loss/gain profile to show energy generation from the earth loop and wind turbines.
- 10" pipe runs underground and into the building for fresh air supply, which is connected to an 85% efficient heat recovery ventilator.
- Ground loop can operate in series with in-floor to provide passive cooling combined with forced air humidity control. This lowers energy consumption (cooling) by approximately 80%!
- 25,000 sq. ft. building heated and cooled using geothermal energy.
- Ground source loop made of 25,000 ft. of 3/4" geothermal pipe.
- 100% of electric energy consumed in the building is purchased from Select Power and generated by Sky Generation, a wind turbine located on the Bruce Peninsula.
- Like the warehouse, offices have efficient in-floor heating and cooling via water-to-water geothermal heat pumps.
- Office flooring made with pre-cast foam insulated concrete to help with in-floor heating process giving a R20+ insulation value between floors.
- Co-efficient of Performance (COP) approaches five in the office and six in the warehouse.
- ClimateMaster Tranquility 27 heat pumps with ClimaDry reheat/passive cooling coils allow for passive cooling with forced air dehumidification.
- Lighting provided by T8 instant-on, high-efficiency lights. Smart occupancy sensors turn off lights when no one is in the room.
- Zero combustion within the building creates an offset of greenhouse gas emissions equivalent to approximately 75 cars annually.
- Insulation is a combination of cellulose, fiberglass and Styrofoam: R46 in the ceiling, R36 in the walls throughout and R14 under the floor.
- Systems are controlled by a web-based program that monitors, manages and displays instantaneous energy produced by the geothermal loop and wind power. This data shows real time loads and consumption of all components in the building.
- Time-of-use electrical rates are optimized by scaling down our energy consumption during high energy cost periods without adversely affecting building temperatures and climate comfort.
- A heat recovery ventilation system uses fresh air supplied through a 100 foot long earth duct to temper incoming air all year.
