The Smith home : a net zero, net metered house in Sackville, NB

April 14 2016, 12:36 PM

The Smith home

Blaine and Heather Smith had a vision when they searched for the perfect spot to build their home near Sackville, NB, back in 1988. The vision was of a sun-filled home with a very small energy footprint. To realize this dream, they chose a house plan with many east and south facing windows to passively heat the home. They installed high levels of insulation throughout and made it air-tight by carefully considering all the construction details to make sure the home would have very low air leakage rates.  

Fast forward to 2012 when the Smiths decided to take this vision one step further and turned their home “net zero.” First Heather and Blaine installed:

  • an air source heat pump;
  • a solar hot water system;
  • a drain water heat recovery system
  • added R-40 insulation in the ceiling

 The cherry on top – of the home, in this case- was the array of solar panels set up on the roof to offset their electricity consumption.  

Thanks to the careful attention to detail and energy efficiency in the construction of the home, the Smiths’ pre-upgrade EnerGuide rating was not bad at 78, but the upgrades resulted in an impressive post-upgrade assessment rating of 90. Orienting their home for sun-filled rooms back in 1988 also paid off -- that decision made their home ‘solar ready.’ It was well positioned to add solar panels and generate energy onsite.

After installing 24 Solar World SW235 Mono V2.0 panels, combining for a total of 5.6 kilowatts capacity, the home now produces as much energy as it uses from the solar panels (on a yearly basis.) This makes it a net zero home. In addition to being net zero, the home is net metered with NB Power for the times when the panels don’t produce enough energy to meet current demand. Credits accumulate for the homeowners when a surplus of power is generated and put back on the grid.

The Smiths were smart to take a whole home approach and to carry out energy efficient upgrades first. It lowered their baseline energy use, making it easier for their solar panel system to meet their energy demands in the run of an average day. By choosing to net-meter with NB Power, they could size the solar system to meet their average daily usage, rather than on a peak energy use day.

For the Smiths, that’s the great benefit to being “grid tied” --their solar panel system is sized for average usage, rather than their peak.

 “We like knowing that 100 per cent of the excess power we produce is used within our neighbourhood,” the Smiths said. ”Aside from the money saved, it is satisfying to do what you can as an individual towards the reduction of greenhouse gas emissions

“Our experience with the net metering program has raised our awareness of our energy consumption and the potential to generate electricity through the seasons,” said Blaine and Heather Smith. “NB Power and our installer (Fundy Solar) led us through the process.” 

“We all use energy daily,” said Heather. “Getting started with meeting your own energy needs is exciting and empowering.”

First Nations field monitor Austin Paul reports from the Saint John River

First Nations field monitor Austin Paul reports from the Saint John River

Austin Paul is an anthropology student at the University of New Brunswick and works with NB Power on the Mactaquac Project. In this guest blog post, Austin will describe more of the activities he was involved in as the First Nations Liaison Field Monitor from writing summary reports for NB Power and First Nations communities to tagging fish with the Canadian Rivers Institute.

During the summer of 2015, I spent most of my days outdoors and worked closely with the Canadian Rivers Institute who conducts various studies in and along the river, this included tagging fish for active and passive fish monitoring.

For active monitoring, the Canadian Rivers Institute scientists place hydrophones in the water that detect tagged fish, which are identified with a unique identification number. For passive monitoring, the scientists have also placed electronic receivers throughout the Saint John River that record where tagged fish pass by. All this collected data will be analyzed and included in NB Power’s Comparative Environmental Review.

To tag a fish, the caught fish is sedated in a solution of fresh water, clove oil and ethanol. Once it is unresponsive to touch, we measure and weigh it. We would also collect scale samples and fin clips for genetic studies. Through a small sterilized surgery, tags are inserted in its stomach cavity and below the dorsal fin. The fish is then placed back into a recovery tank with fresh water before being released back into the river. 

The Wolastoq (Saint John) River is exceedingly important to the First Nations communities.  The river was a natural highway linking many communities throughout the province.  The Wolastoq is greatly respected and thought of as the blood of mother earth. It nourishes the soil and provides sustenance to the people who inhabit the river valley. We are intimately linked to the river.   

For thousands of years, the First Nations people have used the river as a means of travel and established communities along its banks.  Many traces of these communities remain present on the landscape in the form of archaeological sites.  Nearly every river junction and island is host to archaeological sites both large and small.  Many of the artifacts that erode out of the river banks show evidence of excellent craftsmanship and are often made from material that is non-local, demonstrating a vast interaction sphere.  People acquired tool stone from as far north as Ramah Bay Labrador and as far south as the Ohio River Valley. 

These archaeological sites are sacred to the Wolastoqiyik people. When studied, the sites provide a glimpse into the distant past that allows us to form a clearer picture of the ancient way of life and cultural changes over time.  The evidence seems to demonstrate that First Nations communities were highly adaptable to the ever changing environment and enjoyed a rich culture.

 

The information attained through archaeological record is invaluable.  First Nations communities were decimated by diseases brought from Europe, of which the Native population had little immunity.  A great deal of the oral history that had been passed down from generation to generation was lost as many of the elders perished.  It is now through the study of archaeological sites that we are able to gain an appreciation of the remote past.

NB Power’s First Nation engagement commitments are based on inclusion, responsiveness and respect.

As a first Nations Liaison Field Monitor, it is also my responsibility to identify potential First Nations concerns in terms of land use, resource sites and archeological sites. I created a communications plan with the local First Nations to ensure that the information collected is available to those who are interested in it and supported the Mactaquac Project team at the various open house sessions that have been hosted in towns and First Nation communities. 

These sessions were designed to provide further opportunities for community members to voice their concerns and ideas regarding the Mactaquac Project.

Mactaquac and the New Brunswick power grid

Mactaquac and the New Brunswick power grid

We have a big decision to make about the future of the Mactaquac Generating Station. The station is nearing the end of its life, and NB Power is considering what to do next. Whatever is decided will have a big impact on the environment and the people who live and work near the station. That’s why NB Power is working with experts and the public to find out what those impacts might be, and how to lessen them. NB Power will recommend a path forward in 2016. In this week’s blog post, we’ll take you through how Mactaquac fits into New Brunswick’s energy mix and why this decision is so important.

Why was Mactaquac built in the first place?

Mactaquac was built between 1965 and 1968. At the time, the Mactaquac Generating Station was the largest single engineering project in the history of New Brunswick. The project promised more energy on the grid, more jobs through increased productivity of businesses and more outdoor recreational area around the newly created headpond. When it was built, the station was expected to last 100 years.

How important is Mactaquac for the New Brunswick grid?

The Mactaquac Generating Station can produce approximately 670 megawatts of electricity for New Brunswick homes and businesses, which is about 12 % of all the electricity NB Power provides annually. For NB Power, Mactaquac is more than a generating station. It delivers essential services that support a safe, reliable and diverse power grid. In the unlikely event of all stations going offline, Mactaquac’s generators can deliver enough power to kick-start the grid. The headpond also acts as a reserve in case NB Power needs extra load to meet peak demands. NB Power’s 7 hydro stations that over the course of a year generate renewable energy that equates to about 25 % of what is consumed in New Brunswick.


Why did NB Power choose these three options as they are?

The station’s anticipated end of service life is around 2030. NB Power is looking at 3 options: repower, retaining the headpond (no power) and river restoration. These options were chosen for consideration because they are considered technically achievable, and they provide a long-term solution to problems facing the current station. While the options are being studied, NB Power continues to investigate whether new strategies can be adopted to prolong the station’s life and at what cost.

Why don’t you just repower?

As a public utility, NB Power understands that any course of action regarding Mactaquac had far-reaching consequences for all New Brunswickers. There are cost, environmental, social, and engineering impacts to be considered. This is why NB Power is consulting with the public and experts on the choices ahead.

 

Is your home leaking money?

Is your home leaking money?

Older, drafty homes – and in particular, homes built before 1945 that were constructed with little to no insulation – have the biggest potential when it comes to saving money through energy efficiency upgrades. And one of the most overlooked upgrades for homes is insulation.

Insulation: it’s not as sexy as a new granite countertop, but the savings realized through your upgrades might just pay for one. Many homeowners don’t realize that adding insulation is one of the best ‘bang for your buck’ upgrades they can carry out.

You probably already know your home needs additional insulation and/or air sealing if:

  • the walls are cold to touch;
  • you have problems with mold on walls;
  • the floors are cold;
  • you can feel drafts;
  • you have high winter heating bills.

If you experience some, or all, of these problems, your home could benefit from NB Power’s Home Insulation Energy Savings Program. The program offers information and incentives to homeowners to help reduce their energy consumption through targeted air sealing and insulation upgrades.

Participating is easy! Just follow these 5 steps:

1-      Register. Go to www.nbpower.com/homeinsulation and complete the online registration form. If you do not have internet access you may call 1 800 663-6272 (select option 5).

2-      Energy Evaluation. A representative will contact you to set up your Pre-Upgrade Evaluation. This evaluation will identify the upgrades to your home that may be eligible for incentives. The fee for the evaluation is $210+HST.

3-      Receive approval. After the evaluation, you’ll receive a list of recommended upgrades and a pre-approval form. You have 30 days to identify which of those upgrades you wish to complete and return the form to us.

4-      Complete upgrades. Once we have confirmed your participation in this program, you will have nine months to finish your planned upgrades.

5-      Have Post-Upgrade Evaluation and receive incentives. As soon as you’re finished your upgrades (or before the nine month deadline), call us at 1 800 663-6272 to book a Post-Upgrade Evaluation (no cost)
