Couple Builds Energy Efficient Passive Solar Home – Green Building



hey everyone is danielle from exploring alternatives as you know we usually share stories about people living in really small spaces like tiny houses and vans and sailboats in this video though we're going to show you this massive house it's 4,000 square feet and you might be wondering how is this alternative well it was designed and built using sustainable materials and cutting-edge technologies that could be applied to a house of any size and that's why we think it's really cool it's also fossil fuel free so there are no fossil fuels being used to power or heat this house and it's also a passive house and Natasha and Casey who built and live in this home will be explaining more about what passive house means so let's go inside and meet them and talk about their house and their conscious living project we want to build something that we were proud of and that we felt good about that we felt was doing our part and living the way we like to live which is a preventative lifestyle started doing research on Passivhaus and that's when I decided that was direction we wanted to go in terms of performance and then everything else just kind of fell into place in terms of materials and just being in line with what we believe the best way to get to passive house standards is through a super-insulated a envelope a extremely airtight home and orientation so then you orient your house so that you can maximize the sun exposure it's a building standard that's focused on energy consumption this whole back of the house is facing directly south so this house is designed for a passive house standards and the idea is that we get the solar heat gain from the Sun so we have overhangs outside that block the Sun in the summer when the Sun is nice and high and in the winter when it starts to drop then it drops below the overhang and we get all the heat from the south and this glass on the south side has a higher solar heat gain coefficient than the rest of the glass and so what it does is allows the heat to come in lower our value but gives us that heat when the Sun is out this is our bio ethanol fireplace this is how we fill it basically we wanted bio ethanol because it doesn't need to be vented bio ethanol now actually burns extremely clean and odorless so it does start off and visible and it takes about ten minutes and then the flame will really show up the code built house which is basically the worst house that you're allowed to build by law is really the most expensive house to own long run because once you factor in all of your utility costs and and maintenance and things that you're gonna have to down the road it's it ends up being the most expensive home because utility costs are not going down in twenty years from now what's that house gonna be costing somebody – it's gonna be a mortgage payment to heat and cool that house it's cheaper to do it sooner than it is to do it later this is a model of our whole wall assembly and we chose to go with rocks all insulation so this is about 20 inches whereas typical walls nowadays will be about six to eight and depending on what you're putting on it and we chose to go with rocks all also instead of fiberglass rock cells more expensive but it's also it's it's better for the environment it was actually manufactured close to where we are and it also has less pollutants in it so this here is called a drain water heat recovery and what this does is that it takes the water from your shower in this case we have it installed below our ensuite shower and as the hot water goes down the drain which is just lost energy basically the water goes down the drain and then you have a cold water line that runs through this pipe you can see top and bottom there's an inlet and outlet and the cold water goes around the pipe as the hot water is going down so the cold water gets preheated and you can set it up one of two ways you can either set it up so that you preheat the cold water going to your shower so you use less hot water or you preheat the cold water going to your hot water tank so you don't have to heat up as much water after either way it does the same thing and it it's a way to just not lose all that hot water going down your drain if you have about four or five kids this is probably the same a lot of money well the conscious builder only recently came in so it's part of this whole conscious group of companies that we're building so the conscious builder we have this podcast that Natasha and I do the conscious living podcast we're starting an online store called the conscious store which is going to sell environmentally friendly and health-conscious products people understand what conscious means means it awake you know being aware so being aware of the decision so when you decide to put to build a certain way or to use a certain product you're aware of all the implications that that product has so it can be anything from where the product comes from to how the products mate how the workers are treated so this is a cut out of our window it's actually aluminum clad on the outside and fiberglass on the inside with insulated frames triple-glazed obviously and our part of our windows depending on where you go in our house we have some windows that are triple glazed with Krypton gas and some that are triple glazed with argon gas so a big part of a passive house is that it obviously needs to be extremely airtight so if anybody ever says all you need your walls to breathe yes you need your walls to breathe in the sense that you want vapor to be able to travel through it but you don't want air to be able to travel through it so you want your house to be as tight as possible and you want to mechanically control the air coming and going through your house so this is what we put in are you we have to air for hota units as these run 24/7 so it's constantly bringing fresh air into our house and constantly getting rid of stale air from our house and as it's doing that filtering the air so we have fresh air and we're only losing 8 percent of the energy so that means these are 92 percent efficient so this huge thing is our hot water tank it's actually an ADA gal hot water tank but once again because we're fossil fuel free we had to figure out the most efficient way to heat our water and we found this air source heat pump cool thing about this is that it's an air source heat pump so it takes the hot air from the room and heats the water so it's more efficient but in the summer it actually helps cool the house as well in the winter what we'll do is we'll turn off the heat pump part of it and we'll just run full electric so it'll just be an element just like every other electric tank so yes we use more electricity in the winter but it's offset by the savings in the summer so this here is the inverter for our solar panel system we have 10 kilowatt system and we're part of the micro fit program here in Ontario so the cool thing about that is that we just sell electricity back to the grid we're not off the grid and we're not using any electricity directly from our solar panels so we actually basically turned our our roof into a rental unit so where this all started for me was or it hit me is when we had Sullivan that's when it hit me that it's not just about you it's about leaving this earth better than it was I started thinking about what we can do we live what can we do to change what can we change it in the business and then you started thinking about all everything that I see on the job sites and all the stuff that we throw out and all the stuff we put into the houses and you know just from off gassing from the VOCs from different products and laminate products countertops we put all the money at this point into the envelope of our home because it's a lot harder to change that than it is to change to change the aesthetics if we wanted to do it later it's a concrete countertop with an epoxy finish so it's done about an hour away it's better than stone being cut out of the side of a mountain and shipped overseas and cut again and polished and all that so as a obviously concrete's not the best for the environment either but it was the better option for us at this point the floors are all for most farther than the few spots real fine tile is all reclaimed wood and the nice thing about the reclaimed wood first of all we're not cutting down any trees to put this it's all trees that are already down anyways we have the podcast called the conscious living podcast and then kids with Casey's listen Tasha the website is Casey Plus Natasha comm it gives us the opportunity to reach out to people who inspire us and learn from them and figure out how they got from where they were to where they are now really what we want to do is just provide a platform to empower people and educate people and inspire people in all facets of life one of the things that Casey and I always say is lead by example and we try to preach it and to ourselves we are still training ourselves literally to to shop differently for example so we don't necessarily buy brand new we're not into this whole what is it called fast fashion we're literally products are just you know turned over within like weeks so we buy a lot of second hand and consignment and and the food that we eat we try to eat you know locally and organic so we're not you know inducing our bodies with chemicals so we're try to really apply this lead by example to all facets of our life and we're not perfect either right and it's in like I said it's a daily practice we all we can do is the best we can do so that's it I hope you enjoyed learning more about these Green Building Technologies and sustainable materials give this video a thumbs up if you liked it and subscribe to see more like it

    I like this video a lot. I like the whole idea of Green Sustainable housing and development. That is something that I want to do and think it is great. Thanks for the video.

    Why did they not include a solar hot water heater and schedule taking showers and other high volume uses of hot water for late afternoon and early evening when water in the tank is hottest?

    Go for it if you really need a 4,000 square foot house with two-story cathedral ceilings.

    Go for it if you really want, and can afford, a 4,000 square foot house with two-story cathedral ceilings. It is your money.

    That doesn't change that the most cost effective way to be energy efficient is to use less energy. That is most easily done by using only as much space and material as needed to house the occupants. For many, that means a house 1/3rd the size of this house or smaller.

    Consider designing the south-facing wall to facilitate use and storage of pop-in insulation panels to be placed in the window openings at night and other times when solar heat gain is unavailable.

    Four inches of rigid foam has an R-value of 20 or more. Another alternative is operable insulating shutters on the outside which, ideally, can be closed without going outside.

    Heat recovery from a hot water drain can be enhanced by increasing the time that the drain water takes to go down the drain. The drain water will flow quickly through that four inch drain. It will not have a chance to give up most of its heat before it reaches the sewer line.

    Drain into a tank in which the water will sit until it has a chance to cool. The capacity of the tank should be larger than the amount of water used. Cool water will be displaced by new hot water coming in. Heat lost through the sides of the tank heats the room in which the tank is located.

    The inlet to the tank should be at the top of the tank and be designed to maintain stratification of hotter water at the top of the tank. The outlet should be at the bottom of the tank, The heat exchanger should be at the top of the tank.

    The simplest form of heat recovery is to allow water to collect in the bath tub. Pull the stopper only after the water has cooled and given up its heat to the room. Of course, this is not optimal if two or more take baths or showers in quick succession.

    The pipe wrapped around the drain pipe looks good but is unlikely to be optimally effective.

    A plethora of expensive toxic proprietary products stuffed into an airtight spacesuit with tinted windows to obstruct views. Video full of the kind of misinformation weekend warriors regurgitate ad nauseum.

    the funny thing about a house like that, where they are so proud of it, and not disturbing the envirament is…
    HOW MANY TREES THEY TOKE DOWN to build the house (even if you plant new trees!)
    Show the area before the house been builded, would you?

    Can any type of solar ever make financial sense that far north? Was there night insulation for the windows?

    What you do is good but not going to apply to most Canadians. There are more traditional ways to do passive solar without so much equipment. You deserve credit for thinking of others and spending the money in the right places. By the way, what do you drive? That 10 kw system should keep and EV on the road too.

    I take cold showers. I dont need a hot water drain. When you live somewhere where its 110 degrees out. You want to stay away from anything hot

    Nice house, most people won't be able to afford one like it … EVER.
    It must be nice to have money to piss away.
    Being in construction, I'd give an estimate of $1,500,000.
    Not very affordable, even in Canada.

    why not give us a cost analysis, I assume this house seems really viable once you factor the savings over 2 decades, but probably still not as cheap as a really cheap house.

    Confusion between passivhaus / passive house with passive solar design, they are different

    My favorite part was the waste water heat reclaimer (hope I said that right). Never thought of all the energy was going down the drain. Water yes but heat is never thought about.

    Thanks for sharing. Casey really knows his stuff House orientation and air tightness for a passive house. 10kW solar power panels what I would install for that latitude. However, Casey fell for that climate change bolony which has been comprehensively debunked and his ethanol fireplace is horribly inefficient when you take into account the energy used to create the fuel

    The whole idea behind the tinyhouse/vanlife/alternative lifestyle is to have alternatives for those who cant/dont want to spend a fuckton of money just to live. I'm sure warren buffet could build an even fancier crib than these clowns.

    Wahoo there so much high technology and so much taping plastic/Polymere wrap in this house you must have spicy contract with your labours to maintain this plastic wrap efficient beyond the 20 years warranty of most of the components you use.
    So much technology and at the end there is a high electricity consumption.
    That is not saving the planet, that is emphasise fossil industry there is more oil based products stored in the make up of this house than fossil fuel which this house could have consume during its entire life style.
    In 50 years what will you do of all this junk rubbish.
