Prefab Home kits are ideal for Passive House or LEED certified homes
Écohabitationthe French language Quebec affiliates of EcoHome, in conjunction with experienced Architects & Kit home manufacturers, have launched a series of stylish & affordable prefabricated sustainable green kit homesthat are able tomeet Passive House certification standards in North Americaand attainLEED V4 Platinum Certificationin cold climates like Ontario, New York, Vermont, Maine or New Hampshire.
在加拿大魁北克省蒙特利尔2019年世博会上，第一个预制套件房屋模型被剪下了彩带，Eco-Habitat S1600模型(由Ecohome联合创始人Emmanuel Cosgrove所有)在蒙特利尔体育场整体组装，让游客可以穿过并体验预制建筑师设计的LEED /被动式住宅面板住宅的质量和风格。有一系列不同的高性能工具包家庭模型可供选择，还有更多正在开发中-我们在EcoHome正在勤奋地工作，建立关于这些特殊和负担得起的房屋的所有英文信息……
This high performance sustainable kit home model was designed by PARA-SOL Architects, built by Bâtiment Pré-Fab, and assembled by NG3 Construction with the collaboration of the EcoHome & Écohabitation engineers.
The design of the Eco-Habitat S1600 prefab Passive House & LEED standard kit home is optimized for performance & energy efficiency, but to ensure sustainability also meets rigorous environmental standards to provide a high efficiency home with a low environmental footprint, along with a comfortable and healthy non-toxic indoor air quality & environment for the home-owners and their families.
Below is a list of the sustainable & high-performance kit house components & features that Emmanuel chose for his prefab LEED & Passive House home kit - These prefab home kits are configured to individual building lots & owner preferences:
Insulated Slab-on-grade Prefab kit
In it's final destination in the cold climate of Wakefield Quebec, the finishedEco-Habitat S1600 modern green kit housesits on aslab on grade form kit from Legalett在平板下面和外部垂直表面有6英寸的无缝隔热层。As the ground beneath this prefab kit house is expansive clay, a raftslab-on-grade design with solar radiant heatingwas chosen to avoid the costly process of soil remediation that would have been required to build a standard footing and frost wall, or the expense and complication ofbuilding and insulating a basement properly. Raft slabs distribute the weight evenly over the entire surface of the floor rather than having the weight rest entirely on the perimiter footing; this allows for more affordable foundation construction on problem soils like expansive clay or peat.
Chosen Slab-on-Grade Form Kit Brand :
Legalett frost-protected shallow foundation forms- with solar heated radiant floor - see this one go together here:

High-efficiency top-up heating systems
There are three high-efficiency top-up heating systems in thisLEED, Passive House & Zero Energy Ready rated kit house, because as much as this high performance home is designed usingPassive Solar design principlesthere are always periods of the year in cold northern US States like New York, Vermont, Maine or New Hampshire and in Canada in Quebec & Ontario where the sun doesn't shine and we need to keep warm. As this kit house is also a test model for EcoHome, we took the opportunity to try out the following high efficiency heating options so we can measure their efficiency and write about them, but chances are your kit home will only need one of these heat sources:
- An air-heated radiant floor systemfrom Legalett with an estimated 60-70% of the total heat load being provided bysolar air heating panels, which also act to pre-heat domestic hot water in the summer.
- A heat pumpthat operates down to -25 °C that can triple the heat generated per kWh与其他电阻热源相比，消耗的电力(300%效率)。热泵包括一个空调模式。
- High-efficiency wood stove: Wood is a renewable and affordable source of heat in Quebec & North America, which also provides auxiliary heating for resiliency to ensure the home remains habitable during prolonged power outages. Thewood stove combustion is in accordance with EPA requirementslimiting the emission of fine particles.
*See our how-to installation video of the solar air heated floor that this house will rest on
Chosen High Efficiency Heating Brands :
Legalett Solar Air-Heated Slab-on-Grade Form Kits
Powrmatic heat pumps
DF-Jade House, (Pacific Energy Fireplaces & Stove), Wood Stove and (The Grill Bowl), Grill
High-efficiency plumbing and water fixtures
Clean water is essential for life, but most people in North America don't think much about the water they use for drinking, food preparation, and sanitation. Freshwater scarcity manifests itself in the depletion of groundwater, and the drying up of rivers and lakes upon which people depend for irrigation to grow their food. The intersection of water scarcity, food security, and a changing climate on top of it all raises a suite of water concerns for our futures that careful choices of plumbing fixtures and fittings can contribute to help improve the sustainability of our homes.
- Water-efficient fixturesin EcoHome prefab kit homes use only 50% of equivalent new homes in North America
- High efficiency washing machine
- Condensing dryerthat does not exhaust heat to the outside and avoids the need for a dryer vent
- Gray water heat recovery unit: Waste water from the upstairs shower preheats cold water destined for the water heater and recovers approximately 50% of energy with passive operation that requires no maintenance and has no moving parts.
Chosen High Efficiency Low Flow Plumbing Brands :
American Standard, DXV, Grohe, faucet
Germain Larivière, washer and dryer
Ecodrain, gray water heat recovery
Healthy, durable & eco-friendly flooring materials
Back to internal air quality, flooring materials have been chosen for ease of keeping clean and allergen free, while being toxin-free also to avoid off-gassing into the home.

Hello Mike,
然而，喜欢被动家居的想法，有一些基本的问题吗?
1. Aside from purchasing a lot, where would someone begin?
2. Do I understand correctly that I would purchase a kit and have to then arrange for a builder on my own?
3. What is the roundabout cost to purchase the kit? to build? and how long approximately?
Maria
Any responses to the questions above? I have similar questions as well and interested in building a Living Building, Passive and Net Zero cottage in Ontario. Information about cost and flexibility in designs would be most appreciated as I've already designed them and also a Sustainability consultant and LBC Ambassador.
Hi Maria and Lydia
For clarity I have included your questions above, here in bold:
然而，喜欢被动家居的想法，有一些基本的问题吗?除了大量购买，人们会从哪里开始呢?
This page is your best starting place for learning all about passive house –
A certified Passive House in North America & Canada can be certified by the Passive House Institute PHI or PHIUS, the US certification system. Discover the differences to decide which Passive House certification is best for you.
我是否理解正确，我将购买一个套件，然后必须安排一个建设者自己?
是的，你自己会有很多组织工作要做，或者你会需要帮助。即使是一个交钥匙完成的预制组件房，也需要管理安装工作，否则你将需要找到一个项目经理。
安装预制套件屋需要多少额外帮助取决于您选择的包的完成程度。不同的套件屋制造商提供不同完成程度的墙壁组件(例如，安装或不安装外墙板和窗户)。他们可能会为您提供粗糙的框架墙，并简单地提供在现场安装的装饰材料。
并不是所有的总承包商都知道如何成功地提高装备屋的墙壁，所以制造商可能会在你的价格中包含提高墙壁的价格，并将工作分包给他们熟悉的承包商。
购买套件的费用是多少?建立?大概多长时间?
I'll first address timing - that would be based on model size, complexity and level of completion. But for the quickest ones, you could feasibly have one delivered, installed, and be sitting in your brand new living room possibly in as little as 8-10 weeks with certain manufacturers.
The overall cost of a prefab kit house can be pretty much about the same as a site built house, if maybe a bit lower even, but that depends a lot on the package you choose and the local labor rates where you are building. While ‘cost’ may be about the same, it is likely that the ‘value’ is greater, so in that way it is actually cheaper for a truly comparable-quality site-built house.
By value we mean, that these are homes designed by an architect, and that service alone can easily run you 30-40k, with a kit house it is a built-in cost, ergo a bit cheaper than going it alone.
There are fixed costs that will have nothing to do with the kit house itself, like the following, and this is what you would need help from a general contractor with:
For the complete model as seen above (the S1600), you would first contactLegalett for an air heated slab on grade prefab kit, as this house sits on a solar air heated radiant slab on grade floor. And for the house, click on the banner above (at the bottom of this article) to get a quote, and then you will be in our system, so as more info and models become available you will get an email notice. If you run into any other hurdles, you can also drop us a line at[email protected]and we will get you on the right track!
This looks amazing. Exactly what I am looking for in Ontario.
