Systems Summary
The location of the house is remote and can only be found using global positioning system (GPS)
coordinates: 54o 57” N by 85o 28” W. The house is a 15452’ raised bungalow with an east facing
basement walk out and an attached unheated three car shop/garage (see appendix C).
There are many variables involved to successfully design an off grid home and it all starts with
the heat loss and electrical demand. With this information decided the next step is the compilation of
all mechanical systems necessary to supply your house with energy to meet all daily demands
regardless of the weather or time of year.
The energy generation will incorporate both wind energy and Solar Photovoltaic (PV)
generation. This balance between both will provide enough energy to maintain comfort in the home
whether there is no wind or sun, the wind or solar PV will supply enough energy to make up for the
short comings of the other. The energy you generate will be stored in a battery bank that is located in
the battery room which is built inside the mechanical room.
There are other daily living needs we have to address such as the heating and cooling for the
building and domestic hot water generation. The heating and cooling for the house will be a ground
source water to air geothermal furnace. The hot water generation will be accomplished through three
solar thermal flat plate collectors and a desuperheater added to the geothermal water to air furnace
which takes advantage of wasted heat from the compressor.
The completion of the design portion of your off grid build is timed perfect for this upcoming
spring/summer construction season to build your dream home. Comfort will be optimal in your new
off grid build and in the following descriptions you will find all the different systems and steps
necessary to build your dream home.

STRUCTURE AND LOCATION
The house chosen for this design is a 15452’ raised bungalow with an east facing basement
walk out and an attached unheated three car garage (see drawings below).
The location of the house is remote and can only be found using global positioning system
(GPS) coordinates: 54o 57” N by 85o 28” W or with the postal code of the nearest town, Peawanuck
ON P0L 2H0. The property is located just 5km south of Peawanuck on the Winsk River. It will face
west with the west roof housing solar PV panels and the south garage roof the solar thermal DHW
system (see appendix C). (Google Earth, 2015) The house is located on a drumlin, which provides us
with excellent thermal conductivity for a horizontal geothermal system, this will provide better wind
energy production with the towers being approximately 45m above the river.

ELECTRICAL ASSESSMENT
There has been a significant decrease in your hydro demand with reductions in many areas,
the final electrical demand is 34448kWh (Don Rowe, 2000-2016) per day during the critical demand
month (see spread sheet below). This has been reduced from the original design at 152432kWh
(Hydro One, 2009) and further reductions will only improve the outcome. Some large energy hogs
such as the electric stove, electric clothes dryer, and even the curling iron and hair dryers have been
reduced and/or eliminated from the original electrical assessment and this will reduce the costs of
ancillary systems as well. The use of power bars to reduce phantom power loss through electronics
while they are off will also decrease energy demand, every energy management system you can
install now will only save in future expenses for your systems. The energy decrease will generate
savings and where this is first evident will be the reduction of eight batteries to 24.
The drastic reduction of over 50% in hydro demand reduced the solar PV, wind and battery bank
sizes and all have been recalculated to reflect the new electrical demand.

HEAT LOSS CALCULATIONS
The calculations for heat loss were derived from Hot 2K software (see generation report
appendix B) for building heat loss (Natural Resources Canada, 2016) as well as comparing this result
to the Looplink software used to size the geothermal furnace (Lop Link Geo-Connections, Inc.,
2016). The heat loss numbers were almost the same so this confirms our initial heat loss calculations
to be correct. The lower than average heating load can be attributed to the extensive sealing and
insulating of the building envelope. This keeps the heat loss extremely low at just 58% of a
comparable R-2000 home found today. The total heating load is 41491.56MJ or 39.4MBtu. We need
to use Btu (British thermal units, imperial) or Joules (metric) in order to compare the amount of heat
losses and gains there are in the house versus the amount of heat/cooling needed to sustain a
comfortable standard of living (see appendix C for mechanical room design).

SOLAR THERMAL SYSTEM
Lowering the electrical energy demand for off grid living is important, as we have learned,
and with the addition of solar thermal water heaters the electrical demand is reduced significantly.
The location for the panels will be on the south facing garage roof (see appendix C). The solar
thermal system is designed to produce 4.79MMBtu, which is 73% of your domestic hot water needs
for the whole year. Below in the solar assessment information (see appendix B), you can see this new
solar thermal system is going to supplement your domestic hot water demand 100% of the time
through all but a few winter months when there is less sun and much lower temperatures.
The electrical demand for this system will be low, approximately 690W per day for
circulation pumps, compared to thousands of watts a day for electric hot water. This system will
reduce the run time of the electric hot water tank by 73% or 96kW which is equivalent to 1.5hrs a day
instead of 6 or more hours, this will save over 420.4kWh of energy daily. The efficiency of the solar
thermal system is 74.3% according to the manufacturer’s specification sheets which is a higher
efficiency than most other flat plate solar thermal panels. The remaining hot water needs will be off
set again with a desuperheater attached to the compressor of the geothermal furnace capturing waste
heat from the compressor operation to heat hot water (see Appendix A). Some small part (approx.
2%) of the hot water needed will be electrically generated during the month of December only
otherwise the solar thermal system in conjunction with the Desuperheater will supply all the demand.
10. RENW-4004-P01 – Final Design
BY:GORDON LEE 9
BATTERY STORAGE SYSTEM
With the electrical demand greatly reduced to 34.448kW for the new electrical load There
will have to be 24 batteries, that is 8 batteries joined in a series connection, positive to negative and
so on for all 8 batteries this increases the voltage and 3 sets of 8 joined in parallel to increase the
amperage (see appendix C). They will be connected to 4 - 8kW (34kW/day demand) charge
controller/inverters. These will be used for wind and PV energy harvesting and subsequent storage
as well (Don Rowe, 2000-2016). A depth of discharge (DOD) of 60% will add years to the life span
to these batteries, this means more than 1400 charge cycles. Compared to 80% DOD which would
mean less batteries now but would equal just half the number of charge cycles and this means half the
life compared to a the recommended 60% DOD (see battery spread sheet below).
The battery room ventilation system will consist of an exhaust fan and a fresh outdoor air
supply both piped through the wall of the garage requiring two holes to be cored through the
basement wall and two more in the exterior of the garage wall (see appendix C). A hydrogen gas
detector will be used to run the fan as little as possible to maximise energy savings due to exfiltration,
compared to running a fan to equal 1-3 air changes per hour which would be much more expensive.

SOLAR PHOTOVOLTAIC SYSTEM
The solar photovoltaic, or PV, power system for your home is designed similar to a residential
“Micro-Fit” system (10kW) (Ministry of Energy, 2015), it will be sized just a bit larger to utilise all
the roof space available (see generation report appendix B). There will be a total of 11,553kW or
forty 315W panels; these will be installed on the west roof since the solar thermal system is installed
on the south garage roof (see appendix C).
This system will not be capable of providing all the energy you require for daily use
throughout the entire year. We will rely on wind power for the balance of your electrical needs
especially during the winter months. During the darkest winter months, there is not enough radiant
energy from the sun to produce the daily generation requirements to keep your home truly off grid.
December is the critical design month, which is the worst possible situation for solar PV with the
least amount of sunshine, it will only provide 12% of the daily-required energy during the critical
design month. Wind will be the main energy generation during these months, whereas solar PV will
be used in the summer and both will supply the main energy generation for the shoulder seasons
(spring and fall) power demands. There is a distinct lack of large trees at the proposed site; this will
ensure maximum solar gain in both thermal (water/heat energy) and PV (electrical energy)
installations. Keeping trees trimmed as maintaining a clear path from the sun to the panels and clean
panels will keep maximum energy hitting the panels at all times.
13. RENW-4004-P01 – Final Design

WIND TURBINE SYSTEM DESIGN
The main energy generation for your home will be wind, located near the southern shore of
Hudson’s bay there is plenty of wind to provide for all base energy needs. The amount of solar PV
generation is 55% average during the critical design month, or almost 55% of the total daily demand
from the electrical load during the month of December (Hydro One, 2009). This leaves a total
demand of 20.9kWh per day average and this will require two 7.5kW wind turbines (see appendix A)
(Event Horizon Solar, 2016), this will account for the coldest and darkest days when there will be no
solar PV generation (ATPeResources Photo Voltaic Systems, 2010), potentially up to 7 days or more
without sun can happen especially at this time of year and in your build location. The sun may be
behind clouds but the wind will be blowing strong off Hudson Bay and will generate enough
electricity to compensate for the lack of sun. There are wind roses for direction and wind speed
averages for the build site below and in appendix C you can find a layout for all systems in relation to
the house and mechanical room design.
15. RENW-4004-P01 – Final Design

GEOTHERMAL ENERGY SYSTEM
The furnace will be sized using the latest version of Loop Link Software (Lop Link Geo-
Connections, Inc., 2016) (see appendix B) to attain accurate heat loss calculations for this build. We
found with this software 36,500BTU/h (British Thermal Units) of energy used in this house. The
geothermal system will be capable of providing you with optimal comfort with very little use of the
electric supplemental heat that will need to provide 16 kWh per year which can be provided by a
5kW electric heater. The furnace was chosen based on building size and deep earth temperatures. It
will run at an efficiency factor of 3.7 COP (coefficient of performance), this works out to 370%
efficient, you might say wow but this is because of the thermal transfer during fluid circulation
compared to the earth’s temperature (40-50 degrees Fahrenheit). Unless there is a concession made
for fire wood geothermal is the best option to remain completely autonomous and labour free.
