Geothermal System Advantages
Geothermal is a proven technology with millions of units installed world-wide in commercial and residential applications. Geo-thermal is simply the most energy efficient and
environmentally friendly HVAC system that is widely available. Most notably, Geothermal eliminates the need for fossil fuel,
service lines, flues, outside air intake, improvers safety and eliminates carbon emissions.
Other benefits of a geothermal systems include the utilization of diversity within a building, allowing for superior efficiency gains. Mechanical rooms are much smaller, providing square footage gain and results in little or no HVAC equipment on the roof. Self contained compacts units provide a better aesthetic by
eliminating outdoor condensing units, all with a much greater equipment lifespan than traditional systems.
Green Energy Mechanical installs full Mechanical Systems and can provide a wide range of services from full turn-key design and build to small projects and maintenance services.
Consulting, energy modelling and feasibility studies on systems upgrades and retrofit options to improved green technologies can be provided. Green Energy’s wide range of experience,
collaborative design, and wide range of service offerings
allows for a streamlined installation, start-up and maintenance process of even the most advanced energy efficient, water
conserving and green systems. Green Energy’s expertise in
current building and energy codes, energy and water harvesting technologies, grants and green technologies gives their clients a leading edge.

Geothermal Work

1. What is a ground coupled heat pump (GCHP) system?
Animals and people have been taking advantage of energy stored in the ground for along time. Deep earth temperature is about the same temperature as annual average air temperature of the area. In the north earth can be frozen...in a hot climate it can be as high as 27°C
arrow_downward
3. Absorbs energy from buildings in summer
Temperature of the earth is constant. When cooling is needed in our buildings therelatively cool ground easily absorbs heat removed from our buildings
arrow_downward
5. Ground temp is more constant than air temp.
Even when heat is extracted from and rejected to the ground, the temperature variation through the year is much less than the air temperature. Average air temperature range in this area is 21°C, while temperature of fluid from the ground varies only about -1°C
between summer and winter.

7. Heat pumps take advantage of energy stored in the earth
When the temperature of the earth is not high enough to heat the home or buildingdirectly, heat pumps are used to increase the temperature...typically using vapor compression heat pumps to produce warm air or hot water. Heat pumps can also be reversed to provide chilled water or cool air and reject heat back to the earth.

9. Heat pump cools the building and produces hot water
...when cooling the building.

11. Decision to install GCHP system is economic
Most building owners make their decision to install a geothermal system based on economics. Even if they want to do the right thing for whatever reason, it’s difficult to justify installing a geo system if the payback is 50 years.

2. Stored solar energy is extracted in winter
The constant temperature of the earth provides a stable energy source for our buildingsin winter. The ground a few feet down is a constant temperature even though the outdoor temperature drops to -37°C.
arrow_downward
4. Ground heat exchanger transfers energy from ground
By burying plastic pipe in the earth around our buildings and circulating liquid through it,we can access the constant temperature of the earth.
arrow_downward
6. Think of the ground as a storage medium.
One project uses a vertical GHX to store solar energy
collectedby solar thermal panels on 52 homes. The ground
temperature at the end of winter isover 40°C (104°F). Warm water from the ground circulates through fan coil units in the home and provides day or night, summer or winter, with no backup

8. Heat pump heats the building and produces hot water
Adding a desuperheater immediately after the compressor
discharge allows a portion ofthe hottest refrigerant to produce domestic hot water, either when heating the building,
or …

10. Reduced energy consumption
A GCHP system uses less energy than virtually any other conventional HVAC system.Evaluation of the systems in the ASHRAE headquarters, in Atlanta, GA, by Oklahoma State University & Oak Ridge National Laboratory showed the VRF system used 41% more energy in the cooling season (May – September) and 172% more in winter & shoulder seasons (October – April)

12. System construction
The design of the GHX must take into account the site conditions and the availability ofcontractors familiar with the requirements of GHX installation. Site meetings and appropriate quality control / quality assurance inspections during construction of the GHX will pay dividends in the operation and efficiency of the system.

Why Care?
Why Care About
Heating, Water & Cooling?
Why care so much about heating, hot water and cooling? Well because heating, cooling, and hot water uses the most energy in a home, up to 65% of your utilities.
According EnergyStar, “The average household spends more than $2,200 (USD) a year on energy bills, with nearly half of this going to heating and cooling costs.”
