Bottom line was to replace the existing natural gas furnace and electric air conditioner.<P>

Our total investment of $50K will take about fifteen years to achieve some balance. But, that was not our goal. Our goal was to show that it could be done today.

To build a custom home that is sustainable and the most efficient that we can do at this time within reason. Geothermal HVAC, Foam Insulation, Low-E windows, Walkout basement and Water Reclamation.

We broke ground May 6th 2008 and hope to be completed by mid Nov 2008.
6000 Sq Ft home with a walkout basement. We are installing 2-5Ton WaterFurnace open loop water to air units into 5 zones. We drilled a 300' water well in the front yard and can pump 18GPM at 68 degrees.
The Geo waste water will be dumped into a 2000 septic tank only for this water and reused for irrigation. Any left over water will overflow into the natural creek on our site.

Performance of my PV system and details to consider when planning a PV system are described at:
http://milo-scientific.com/pers/PV_system/

Located in Dartmouth Nova Scotia, Thermo Dynamics Ltd. manufactures liquid flat plate solar collectors, solar systems, solar pumps.

Our 10,000-square foot factory is heated by thirty (30) G32-P solar collectors located on the south wall of the building, and a small natural gas boiler. Our heating costs for the past 6 years has been about $1,000 per year.

100 Thermo-Dynamics 3x8 Flat-Plate Solar COllectors. System installed by Doctor Solar of Scotian Renewables Inc.

Likewise, where radiant heating was quoted at between $30,000 and $ 45,000, we got a very detailed design and the complete installation kit from the great folks at www.nrt.com and installed it with a bit of help from the plumber. The result is a 6 zone radiant system operated by a Climate Master 5 ton (turns out to be much more than we needed, typical HVAC oversizing...see graphs) water to water Geothermal Heat pump operating off our domestic water well. First year ran just over $ 1,200 for both heat and hot water. We expect to do better next year, since we're fixing all the sloppy air infiltration our awful builder didn't do properly.

This is a test case for a potential wider scale implementation of WEL for monitoring the performance of a number of home energy efficiency retrofits.

Large south oriented windows provide enough passive solar to completely heat house from 10am to sunset on sunny winter days above 30 degrees. There is 6'' thick exterior stone on southern walls to maintain heat into evening. Deep roof overhang shields sun in summer.

HAI intellegent staging thermostats used to maintain the more efficient low speed HP operation as much as possible. They only add stage 2 when user specified heat rise rate is not being met in stage 1.

Loop one has 6 vertical wells connected to two 3-ton AC systems

Loop two has 3 vertical wells connectedd to one 2-ton AC system

Only ground loop temperature sensors installed thus far.
System installed by Palace Geothermal, South Jordan, UT.

Also recently added a GE 50 gal. heat pump water heater with an 80 gal. tempering tank. This is an excellent combinatin that has reduced the electric power cost for domestic hot water by more than 60%.

-Pool heating
-In-floor radiant pre-heating
-Solar domestic hot-water pre-heating

2 Collectors pre-heating the domestic hot water.

It works great - when the sun shines it heats water. There is nothing for the homeowner to adjust, no annual maintenance and no reliance on grid electricity. It will not overheat or freeze-up; it just works.

The primary purpose of this implementation is to understand the WEL's serial logging capabilities and to illustrate control applications by interfacing 3rd party products to the WEL.

We also have a Marathon (MR50245) 50 Gallon 4500 Watts Electric Water heater.

Our house was built in 2002. The house is 2500 square feet with 2'' by 6'' framing on exterior walls and R19 insulation. The attic has R30 insulation. The house has Andersen Windows with high performance glass.

The geothermal heat pump replaced an inefficient Hallmark oil fired furnace. The Marathon water heater replaced a Bock oil water heater. We have cut our dependency on fossil fuels as we no longer need oil to heat our home or our domestic hot water.

We have been researching the WEL for awhile. We are hoping to get a better understanding of how our system is performing and monitor in greater detail our temperature sensor data and monthly heating and cooling costs.

(Posting since 2010)

I hope to monitor the behavior of the the geothermal unit,
and validate that it does not use the backup electric element too much.

As I am going to do some monitoring, I also intend to monitor many points in the house to see how well the whole setup is balanced.

Finally, I am also monitoring the electric current at many points, and I want to correlate all this.

Started operation in may, 2011. First logging setup completed in march, 2012.

The gas water heater is on a timer that only allows it to fire up 5pm-6pm, and 3am-4am. So when we use water in the morning, the solar system has a chance to reheat it before the gas kicks in, and if the tank is not still warm after the evening usage, the gas comes on in the early AM so we have hot water in the morning. This appears to reduce the gas operation by quite a bit, over and above the savings from not having a pilot light.

In mid-2011, I installed a BSSI DeltaT+ controller that turns off the PV-powered pump if the collector is not warm enough. This avoids almost all energy losses from circulation in the morning or evening when the collector is cold.

23 May 2012: I installed a sensor so I can now measure and record output from the solar electric (PV) system as well as the solar hot water system. The sensor cost about $10 in parts.

Note...

Temp sensors on Tank and Hot Flow are not accurate living data, still a building site.

Outside temp accurate

Other sensors are not accurate, still a building site

Hot tank heated by spare PV power with auto divert switch on output when house load is less than PV output. Power diverted to 3Kw immersion.

The ''Cottage'' was built in 2005 using 2x6 Walls (R21)and R44 Ceiling. Lakeside has lots of windows and we originally used a 90-plus propane furnace to heat the 4350 square ft of living space. Geothermal was installed Sept 2011 with the propane furnace being left in place for emergency heat.
A Honeywell TZ-4 Controls the Zone Dampers used to divide the heat load in half (Upstairs Zone2, Downstairs Zone1). Smart-House technology was installed using a HAI(Home Automation,Inc) controller with associated alarm, relays and sensors.

The ClimateMaster TT27 6 ton unit, non-pressurized (QT) system is supported by a closed loop (3 trenches each300 ft long), using a 6 pipe configuration in two of them, and a 4 pipe configuration in the third. The 4800 foot of 3/4'' pipe has an average depth of 8 ft in saturated clay (standing water table equalized with the lake bed).

We are Andrew, Julien, Josh and Kevin and we are Team 3 of Dalhousie's mechanical engineering design class! We are designing a completely autonomous system which will use the output power of several solar panels to heat domestic hot water. When the water is up to temperature, the excess power will be used to charge a bank of batteries. In theory, with PV panels, every kWh of energy can be used.

System will also contain three ducted zones w/thermostats, a de-superheater loop to a two-tank DHW system, timed circulation to hot water use points, heat recovery ventilator, electronic air filter, and humidifier.

All electric home in a 13¢/kwh environment at 5852 heating degree days. ASHRAE winter design temperature for this Sierra Nevada 3500' mountain location is +10°F. Projected total cost in January is $170 or less for heat, hot water, lights, refrigeration, cooking, and laundry. That's $5.20/100sf/month.

Rather than building a traditional ''Energy-Hog'' home, or even a non-traditional Energy-Efficient home, our new home is a unique fusion of energy efficient techniques, and environmental sanity.

Our goal was to create a home that uses the sun, earth and water to create a pleasant living environment where we can enjoy the wildlife, and which also reduces our demands on non-sustainable resources.
