Lofty Energy Saving and Eco Design Goals

A building project is a long series of design choices. Some are prescribed and imposed by regulations but many come down to personal preference and often a little bit of off-the-beaten path exploration.

A key component of a community for tiny houses on wheels, perhaps ironically, is the presence of a structural dwelling on foundation. For Big Calm, this is the completion of a pre-existing, unfinished post-and-beam barn-loft we call the Shangri-loft.

In restoring it, we’ve been mindful to use safe materials (like low VOC paints) and to integrate several generally-available eco-friendly or energy-saving innovations. Here are some of them:

Handful of washed sand

Septic System

Behold the elusive Type 2 septic field special sand blend! We never thought we would be so happy to see sand but after a months-long delay it finally arrived just before winter! We chose to build a Type 2 community septic system because it takes up half the footprint and produces much cleaner effluent, compared with standard (Type 1) systems.

Insulation

It may not look like much – just spray foam on a ceiling – but we waited for this spray foam for months. What a relief to finally complete the Shangri-loft’s insulation in the midst of supply chain delays!

The barn ceiling required spray foam, rather than the R50 rock wool batt insulation we used for the rest of the building. Always trying to make the best choice for our community members’ health as well as the health of the environment, we opted for a spray foam with an environmental product declaration demonstrating it has one of the lowest global warming potential impacts of any insulation product. It is low VOC (Volatile Organic Compounds) and contains 22% recycled plastic and renewable soya oil. Worth the wait. 🙂🌎

Heat Pump

We’ve built the Shangri-loft to meet the BC Energy Step Code level 4, meaning the Shangri-loft will be 40% more efficient than the EnerGuide Rating System’s reference house. We’ll be heating (and cooling) the Shangri-loft with an Energy Star-rated Bosch heat pump, which can transfer 2-3 times the energy it consumes!

Drain Pipe

This shiny coil is a ThermoDrain, an ingenious heat recovery pipe made by Canadian company EcoInnovation. Installed in the mechanical room beneath the Shangri-loft’s bathroom, it uses the heat from wastewater to de-cool the fresh mountain water coming in to the hot water heater. The overall saving is up to 40% on the cost of heating water.

(Also built into this mechanical room is a connection for a Portable Electric 2k or 5k Voltstack battery generator, a backup for power outages.)

A tile of black Marmoleum Click flooring

Flooring

We agonized over what flooring to put in the Shangri-loft. We wanted something durable, easy to clean, and of course, environmentally friendly. Enter Forbo Flooring System’s Marmoleum Click (it’s the new linoleum): made from 97% natural materials, 70% of which are rapidly renewable, and made of 43% of recycled content. It’s also carbon neutral. And it doesn’t look to shabby either! 😉

Lastly, some of the simplest things anyone can do is to buy local (as we’re doing with the baseboards and window/door casing) and to re-use materials. Perhaps our sentimental favourite item was to salvage a big steel heat shield from the original homesteader cabin on-site and place it above a cute new TN10 wood stove. Old and new together.

Project Update (Year-end 2021)

2021 wasn’t an easy year in which to build a project like Big Calm. Slow bureaucrats, busy contractors, wildfire evacuation (just as crews mobilized), supply chain hold-ups (from septic field sand and insulation to doors and appliances), and, oh yeah, that persistent pandemic thing.

Despite all that, we’ve made good progress on the project. Here are some photos of the work done to date.

Power, water, and tech lines were trenched out to the Shangri-loft (which will eventually serve as the shared community space). This includes stubs for a well and future solar array.

Septic tanks were placed at the Shangri-loft and the Type 2 community septic field was excavated and, with the long awaited delivery of sand, partially activated. This is the biggest component of the whole project.

Earthworks were also completed on two fully serviced tiny house pads – one by the old homesteader cabin and one by the Shangri-loft. The former is now home to The Pocket Getaway and the latter is reserved for the arrival of our first long-term renter this spring.

Much of our focus this fall has been on the Shangri-loft itself; renovating a beautiful, unfinished post-and-bean barn-loft that will be Big Calm‘s centrepiece common area (laundry, bike/ski storage, social space). Work included shoring up its foundation, framing in a bathroom and kitchen upstairs and a laundry room downstairs, and, currently, implementing various electrical and mechanical systems.

We’ve been part of Starlink’s beta rollout since March and have been very pleased with internet connectivity on-site.

The fiery summer stunted some of our permaculture plans – at least those in the garden. Nonetheless, we enjoyed a tasty harvest of potatoes, carrots, and Jerusalem artichokes. And we had time to observe – where the water flows, the wind blows, the plants grow, and the animals roam.

So what’s next? In 2022, we plan to grade the access road, extend earthworks out to the community pad sites, install the well, and finish the remaining phases of the septic system. We are working on investment financing to accelerate the buildout to meet the very high level of renter interest.

We’re optimistic for the new year and are looking forward to the community starting to take shape. Be sure to sign up to our newsletter and follow us online for continued updates.

The Bigger Picture on Tiny Homesteads

When we first contemplated building a tiny home community in the Slocan Valley, we thought a lot about how it would impact, and ideally, benefit both the land and the larger community.

Environmental Impact

Earlier this year, I was working on a project to support the region’s licensed cannabis producers, and had the honour and privilege to participate in cultural sensitivity training by members of the Sinixt First Nation, on whose land we work and reside. I learned of Whuplak’n, a Sinixt law that guides us to take care of the land, water, air and all living things. If we take care of the land, it takes care of us: all decisions should be informed through this process of what is in the best interest of all living things. 

Big Calm is aligned with this law. We want to take care of the land so it takes care of us.

Minimal Development, Modest Community

We purchased the property we call Big Calm because it was already ideal for a pocket neighbourhood, with no clearing or major earthworks required. The only development work needed involves smoothing the driveway, drilling a groundwater well, servicing each (gravel) tiny home pad, and installing a septic system. Despite the significant cost, we opted for a Type 2 septic system, which has half the footprint of a Type 1 system and generates much cleaner effluent. In this case, as in many others, eco-minded choices come at a higher cost, but to us, it’s worth it. 

The community will be situated on roughly three of our 30+ acres. Guidelines for RV park developments recommend 10 units per acre, which translates to 30 units for our community space. We decided on only 10. Water is our most precious resource, and after consulting with a civil engineer, we determined that 10 tiny homes is both conservative as well as sustainable. Of course, the other benefit of having only 10 pads is that we can truly offer tiny homesteads, with plenty of space and privacy, with the comfort of a community not too far away.

Tiny Home Living

It’s intuitive that tiny homes take up a smaller footprint than conventional homes and generally use less electricity and water, of which the average Canadian uses 330 litres per day. Tiny house dweller and blogger Joshua Engberg determined that his daily water use was just over 66 litres, about 20% of the average Canadian’s use. In terms of electricity, the average Canadian uses 13,891 kWh per year, while a tiny home uses only 1,515 kWh per year, or about 11% the national per capita average. Based on these statistics, 10 tiny homes would use roughly the same amount of water as two conventional homes and about the same amount of electricity as one conventional home.

And, that doesn’t take into account the electricity- and water-saving measures we, and future tiny homesteaders, plan to employ. Not surprisingly, the majority of individuals interested in living at Big Calm also plan to install solar panels on their tiny homes, which will complement the large solar array we plan to install in the mid-term. Even though tiny homes have a small water catchment area, prospective tiny homesteaders still want to harvest as much water as they can. We’ve also heard from folks planning to have compost toilets in their tiny home, which can save more than 25,000 litres of water per person per year!

Maria Saxton, a doctor of environmental design and planning, conducted a study to measure how downsizing to a tiny home influences downstream environmental impacts. She found that the average ecological footprint required to support a tiny home dweller for one year was about 9.5 acres, compared with 17.3 acres for an individual living in a conventional home, a decrease of 45%. She adds that the impacts are even further-reaching:

“On average, every major component of downsizers’ lifestyles, including food, transportation, and consumption of goods and services, was positively influenced.

 

As a whole, I found that after downsizing, people were more likely to eat less energy-intensive food products and adopt more environmentally conscious eating habits, such as eating more locally and growing more of their own food. Participants traveled less by car, motorcycle, bus, train, and airplane, and drove more fuel-efficient cars than they did before downsizing.

 

They also purchased substantially fewer items, recycled more plastic and paper, and generated less trash. In sum, I found that downsizing was an important step toward reducing ecological footprints and encouraging pro-environmental behaviors.”

Permaculture-Guided

Climate change is an overwhelming issue for everybody. What I love about permaculture is that it is a way for individuals to do their part to care for the earth. Permaculture doesn’t aim to be merely sustainable, it aims to be regenerative. It builds soil, captures carbon, promotes biodiversity and produces food in a way that isn’t destructive. 

We have grand permaculture-related plans for Big Calm. We envision pollinator gardens, a food forest and a greenhouse to extend the growing season. Permaculture is a means by which we can give back to the land, become more self reliant and create community bonds. We are thrilled that everyone we’ve spoken to can’t wait to get their hands dirty!

Community Impact

When we first conceived the concept of Big Calm, we wanted to ensure that it would have a positive impact on the larger community. Affordable housing in this part of BC is a complex issue that will require institutional support and substantial funding to address, and is not an affordable undertaking by us regular folks, unfortunately. 

In an article on the investment needed for dedicated affordable housing Marc Lee, Senior Economist at the Canadian Centre for Policy Alternatives, says:

“A housing commitment to build 11,400 units a year for a decade translates into an annual public investment of about $3 billion ($250,000 per unit construction and related cost), assuming public land owned by local governments or the provincial government is contributed.”

Despite not having the substantial capital required to take on the issue of affordable housing, Big Calm can still have a positive impact. In an article in The Tyee, Guy Dauncey, author of Journey to the Future: A Better World is Possible, posed eight solutions to Canada’s housing crisis. One of them was the development of new villages. He says:

“Many younger people want more than an affordable home. They also want to live sustainably with a strong sense of community. They want to build a sharing economy, with a lighter footprint on the Earth. They want to build their own eco-villages and tiny home villages.

 

An eco-village places more emphasis on sociable, pedestrian-friendly designs, habitat protection and solar energy and passive homes than a conventional development. We should train people how to become their own developers, forming eco-village development co-operatives, raising the money needed and navigating the complex world of zoning and development approval.”

My only gripe with this is that it’s not just younger people, it’s people of all ages, including families, independents, and a large proportion of individuals who are retired or planning to retire soon and want to live a more sustainable lifestyle.

Because Big Calm is attracting remote workers–who will bring their jobs with them–to new residential units, we will not exacerbate the issue of lack of affordable housing. We believe we can have a positive economic impact on the community: we hope our modest project–which is being developed by local contractors; tradespeople; and civil, structural and geotechnical engineers–will potentially relieve some pressure on the middle-market. Not to mention that the Big Calm community will volunteer at local events and support businesses by shopping locally.

“More people are now wanting to relocate to the valley, recognizing it for the gem that it is.” 
– Slocan Valley Economic Development coordinator (Valley Voice, October 8, 2020)

We are thrilled with the calibre and diversity of individuals interested in Big Calm, as well as their desire to contribute not just to the Big Calm community, but to the larger community as well. We’ve heard from individuals who want to share their knowledge of / expertise in laughter yoga, leadership, mindfulness, movement, art, group building, positive therapy, meditation/guided visualization, permaculture, gardening, photography/videography, presentation development, detoxing, raw vegan cuisine, mental wellness, and close community living. We’ve had the pleasure to meet a semi-retired midwife, financial analyst, insurance underwriter, soil scientist, leadership coach and yoga instructor, among others. A desire to live sustainably, care for the land and be part of a supportive community is the common thread that unites them.  

Do you have any other ideas that would help us positively impact the environment, the community and the larger Slocan Valley Community? Please share them with us at hello@bigcalm.ca.
