The logical solution

• The systems principle of operation

• The advantages of geothermal systems

• Anticipated profits for you and your customers

7
Principle of operation

• The ground is like
• a humid sponge
• We can extract
• water from it
• It can absorb
• water

In the same way, the ground can provide us with
heat and it can absorb it.
8

• The ground temperature remains constant
  throughout the year.

Compressor 1 KW
T 8C Énergie non-exploitable
4.6 KW
T 45C Usable energy

• For each KW of energy furhished by a compressor,
  we obtain 4.6 KW of usable energy

11

• Studies show that close to 70 of the energy used
  by a geothermal system proves to be
• renewable
• energy
• comming
• from the
• ground

12

• Geothermal systems circulate an aqueous solution
  through pipes hidden under ground forming a
  system of loops .

13

• The geothermic system is not at all influenced by
  the outside temperature. The geothermic heat pump
  will function even at the extreme temperatures of
  summer and winter.

14

• During winter, it is easier to recover heat
  below ground at a temperature of 8C. than above
  ground where the surrounding air is at a
  temperature
• of -17 C.

15

• Operation principle of a geothermic heat pump
• In heating mode, the cold circulating liquid
  absorbs heat from the ground. This heat is
  recovered by the heat pump.

16

• In summer, the cooler ground absorbs the
  surplus heat from houses and buildings more
  efficiently than the hot air above ground.

17

• Operation principle of a geothermic heat pump
• In air-conditioning mode, the hot liquid
  disperses its heat in the ground and returns from
  the underground
• loop at a
• lower
• temperature.

18

• Electrical power is used to concentrate heat and
  to move it from one place to another. By
  comparison with a traditional system, the energy
  consumption is reduced by 30 to 70 in heating
  mode and by 20 to 95 in air-conditioning mode.

19

-Lower air T

• Air not as dry during the
• winter

• We do not have to worry about varying outside
  temperatures.

• During the summer, the system acts as a central
  dehumidifying air-conditioner

22

• No chimney

• No odors

• No danger of smoke or fire.

23
Noise and Esthetics

• The units are installed inside the building.

• Reduced maintenance and security fees

• Increased security against vandalisme

• The buildings appearance remains
• unaltered

• No noisy equipement outside the building.

• The equipement is silent

24

• Other advantages of geothermal systems.

• Reduced space requirements

• The system may be entirely electrique

• No connection to gas services

• No fuel reservoir

• Small mecanical room

25

• Other advantages
• Maintenance fee savings

• The interior units are not exposed to weathering,
  saline or acid environments.

• Units have much longer
• life spans (above 20 yrs.)

• Unit replacement fees are greatly reduced.

• No need for costly cooling or heating units.

26
Savings due to energy efficiency

• Geothermal systems are high efficiency systems
  requiring less energy than conventional systems.
  (COP from 3.6 to 6)

• No high peak demand system require in heating
  mode.

• Annual electricity, gas or oil savings greatly
  compensate for the higher inital cost of the
  system.

• A geothermal system can even generate a positive
  cash flow, if the system is financed with the
  savings it provides.

27
Savings due to energy efficiency

• Reduced high point demand

• The use of a controling system may even eliminate
  the high point.

• The period of return on your surplus
  investissement, relative to a conventional
  system, varies from 0.5 to 5 years and is normaly
  within 3 years.

  According to the US EPA (Environmental
Protection Agency) and the MNR (Minister of
Nutural Ressources)

• geothermal systems can reduce the energy
  consumption by 40 compared to a conventional
  heat pump

• and by up to 70 compared to an electrical
  resistance heating system.

28
Environment

• A geothermal system releases no C02, one of the
  major contributors to air pollution. We use the
  earths natural energy, a renewable resource that
  Mother Nature graciously provides us with.
• Using geothermal systems substantialy reduces the
  quantities of green house gases released in the
  atmorsphere when replacing fossil fuel
• based systems.

• Coupled with other renewable energy sources
  (hydroelectricity, wind mill produced energy,
  photovoltaic energy), the use of geothermal
  systems is an advantageous and sensable choice
  for society.

37
Financial incentives

• The MNR via Canmet offers incentives to permit
  the introduction of geothermal systems in
  building design.
• Following are two of the main available programs

• Energy Innovators Initiative

• Commercial building incentive programs (CBIP)

38
Energy Innovators Initiative

• This program aims at improving existing buildings
  whose energy expenses are at least 100,000.00
• Planning
• Refund 50 , or up to 25,000.00, of project
  elaboration and planning fees
• Acceptable activities
• Energy requirement evaluations
• Feasibility studies
• Energy management plans
• Other project elaboration services

39
Energy Innovators Initiative

• Building improvement (3 or less)

• Only projects with 5 000 GigaJoules per year (1.4
  MKWh) of projected savings are admissible.

• Admissible commercial enterprises or public
  institutions can receive 7.50 per saved
  GigaJoule up to a total of 250,000.00 or 25
  of the admissible project costs.

• It is necessary to prepare an exhaustive energy
  management plan and to have been registered with
  the programs

• We must re-examine all the energy saving aspects
  of the buildings such as lighting, fenestration,
  heating-air-conditioning, water-heaters, engines,
  the training and sensibilization of employees,
  etc.)

40
Energy Innovators Initiative

• Building improvement (3 or less)

• Example 
• A 15 000 m2 (161,000 ft2) building for which the
  annual energy consumption and invoice amount
  respectively to 25 000 GJ (6.9 million kWh) and
  to 300,000.00.

• By means of the efficiency improvement project
  whose cost is 300,000.00, you forsee reducing
  your consumption by 20 and saving 5 000 GJ or
  60,000.00 per annum.

• Support is determined as follows
• 7.50/GJ X 5 000 GJ 37,500.00

• The project will thus have cost 262,500.00 and
  one will obtain a return on the investment in
  4.38 years through energy savings. Thereafter,
  these improvements will produce a minimum economy
  of 1.2 M for the next 20 years without taking
  into account energy cost variations.

41
New commercial building incentive programs (CBIP)

• This program offers a financial incentive for the
  integration of econergetic characteristics in the
  design of commercial and institutional buildings.
  The owners whose buildings respect the CBIP
  standards will receive a financial incentive
  which can reach 60,000.00
•  
• The building plans must show a reduction in
  energy consumption of at least 25 compared to
  the MNECB standards (Model National Energy Code
  for Buildings)
• The program is offered until the March 31, 2004.
• The IBIP program extends the CBIP to the
  industrial sector where the contributions can
  reach 80,000.00. This program is valid until
  March 31, 2006.

42
New commercial building incentive programs (CBIP)

• The contribution is twice the difference between
  the forseen annual energy costs according to the
  MNECB and the approved econergetic design.

• Example 
• Forseen energy costs according to MNECB
  100,000.00
• Minus the forseen costs according to
• the CBIP design 75,000.00
• Forseen energy savings 25,000.00
•   CBIP grant 25,000 X 2 50,000.00

• Econergetic buildings procure long-term energy
  savings. Lower exploitation costs increase the
  resale value of the building and comprise a
  competitive advantage in rental capacity compared
  to traditional buildings.

43
RETScreen Software

• We recommend the use of the RETScreen software
  which is provided free of charge by Natural
  Resources Canada and CANMET. This software is a
  decision-making aid center in renewable energy.
•  
• The software permits the analysis of projects and
  of the application of various technologies like
• -o       wind mills,
• o       small hydroelectric plants,
• o       photovoltaic cells,
• o       solar heating,
• o       biomass heating,
• o       solar heating of water,
• o       passive solar heating and
• o       geothermal heat pumps.
•  
• The software also gives access to weather data
  and data on the equipment available for all
  technologies.

• DX SYSTEM Principle of operation
• 1. The coolant penetrates in the interior
  serpentine (evaporator) during the process of
  air-conditioning. While entering the serpentine,
  the temperature of the cooling agent ranges
  between 40 and 50 F.
• 2. As the hot and humid air circulates around the
  serpentine, the cooling agent absorbs the heat.
• 3. The air becomes colder
• and dryer and is then
• recirculated in the
• room by means of a
• ventilator.  

45

• DX SYSTEM Principle of operation (continued)
•  4. The cooling agent moves in the compressor
  (pump) which increases the pressure and allows it
  to circulate in the system. The increase in
  pressure caused by the compressor leads the
  cooling agent to be heated to a temperature of
  approximately 120 to 140 F, now in the form of
  vapor.
• 5. The hot vapor circulates in the condenser (the
  underground loop) where the cooling agent
  releases its heat to the colder ground and
  condenses again to liquid form.
•  
• 6. When the cooling agent
• leaves the compressor, it
• is under high pressure and
• remains so until it reaches
• the expansion valve. At this
• time, the pressure is reduced.
• 7. The cycle is completed
• when the low temperature coolant enters the
  evaporator and again collects heat from the air
  in the room.
