Your Sustainable Tiny Home – Insulation

Posted on

One of the best ways to make your tiny home sustainable, and comfortable to live in, is to insulate it properly.  For the houses we build, we include as part of our standard packages a combination of spray foam insulation and fiberglass insulation.  We also recommend adding a cost-efficient mini-split to heat/cool your home.  In most climates, this works well.

Planning on regular travel with your movable home? Nathan, Tiny SMART House, CEO and Founder, suggests upgrading to spray foam as it weighs much less than fiberglass.  An added benefit its rigidity to withstand the impact of travel.

The benefits of spray foam insulation abound:

  • It creates a vapor lock so that condensation is not an issue
  • Since it repels water, mold is not an issue
  • A wide range of air pollutants are sealed out
  • It reduces noise
  • Critters don’t like to make a home in spray foam
  • It improves R-value and reduces energy costs up to 30%

The Greenest Upgrade

Last winter, we toured the Havelock Wool factory in Reno, NV.  It was exciting to learn about their insulation as it is all-natural (no chance of getting itchy as you do if you’re not careful with fiberglass!). For tiny houses on wheels, it offers a lighter weight and compares well efficiency and cost-wise to other insulation.  We heard about a 44’ gooseneck being insulated before going to a customer in Alaska.

One benefit of sheep’s wool insulation is its breathability and moisture control properties. Sheep’s wool can absorb moisture in the air without compromising its insulation abilities. Natural keratin makes it naturally resistant to mold and mildew.  Wool will not support a flame below 1100F.  Havelock Wool conforms to Class A of the ASTM E84 test (the fire rating). Besides not having to worry about off-gassing, wool can even filter and improve your air quality.

The wool comes from sheep raised in the rain-fed, grass fields of New Zealand.  Farmers care for their flocks, and are known as the best when it comes to sheering and cleaning practices.  If you so choose, you could recycle or compost your wool insulation – a benefit none of the other types offer!

Potty Questions – Composting Toilets

Posted on

One of the easiest off-grid living options is using compost toilets.  Fresh water is becoming a scarce resource in many areas, and if living off-grid (even temporarily), you may want to explore options that use no water.  Having one installed in your tiny house on wheels means you could even eliminate having a black tank, and not have to worry about hooking up to a septic system.

Nathan, Tiny SMART House’s President & CEO, recommends the newer type of compost toilets as they are better for dealing with humanure.  Nature’s Head and Separett have urine diverting designs, and are the ones we use and recommend to our clients.  This means that the relative lack of fluids in the storage tanks help eliminate odor and enhance the complete and rapid composting of the solid waste.  Older composting designs hold urine and solids in one tank, and need heat and rotation to help liquids evaporate.  Since there is usually more liquid than can evaporate quickly, you need to add peat moss, coconut fiber, compost starter or sawdust.  (Which means storing the sawdust, etc.  Do you want to use valuable storage space on that?)

Composting toilets require almost no maintenance and are impossible to plug.  Fans are used to dry out the contents, and are usually very quiet.  Ventilation is required, and we make sure that the pipes are properly vented to the outside so you never smell anything inside your tiny home!  Depending on the type of composting toilet you have, and how many people using it, it can be several weeks (or more!) for the solids bin to fill up.

If you decide to use your humanure as compost, be sure to learn how to take care of it properly.  Solid human waste can pollute water. Don’t use it on any edible plants.  Do use it on your pretty flowers! Lime will drastically reduce the time your compost needs to sit. Pee is easy, as (at the household level) it can be used directly (or slightly diluted) as fertilizer safely.  Urine can go into a gray water system (with the shower or sink water), or it can be drained into a rock pit. To learn more about composting and how to properly compost humanure, Nathan recommends these two articles: “Hot Composting How-To Guide” and “How to Safely Compost Human Waste”

If, after using your compost toilet for a while, you decide it’s not for you – don’t worry!  Here at Tiny SMART House we install a flange in case later you want (or need) to install a flush toilet.

Potty Questions – Incinerating Toilets

Posted on

incinolet toilet

There are so many options when it comes to what kind of toilet to have in your tiny house, you must have lots of potty questions. To help answer them, here’s another option for dealing with your bathroom business – the incinerator toilet systems. If you are not familiar with these, the idea behind them is that your excrement is heated until all that remains is sterile and harmless ash. Typically taking around 6 minutes to process wet matter and 45 minutes to an hour to process solids. Typically costing around $2,000 they are an investment and newer models can be used in tiny houses that are frequently moved.  

The big thing to consider if opting for an incinerator toilet system is your power source and building to accommodate the bulky disposal unit. Brands such as Incinolet and Ecojohn offer units that can be electric, propane or solar. These units will use a fair amount of energy to operate and the type of power source will affect your out of pocket. You will only have ashes to deal with and that may very well make this an investment that has its own rewards.

Potty Questions – RV Flush Toilets

Posted on

RV Flush toilet

When considering the management of waste in your tiny house, one almost immediately thinks of the toilet. Perhaps the most daunting waste to manage and the least pleasant to entertain thoughts on. If you have the ability to connect to a septic system (meaning where you’re parking your tiny house is hooked up to a sewer system or has a septic tank you can splice into) you can install a flushing toilet.

However if you are  unable to access or install a septic, then you may want to consider using a black water tank. When the black tank is full, it will need to be dumped in a specified locations. Often chemicals are recommended to keep odors down. If you are going off grid your options are fairly tricky.  This is why many who boondock or live off-grid use alternative toilets.

The expense of the toilet unit with using a septic or tank is the same ranging from around $100+ for a Dometic plastic RV commode, all the way up to a very high-end Toto Neorest .  Here at Tiny SMART House we offer a standard option of a porcelain home toilet.

The great thing about flushable toilets is the ability to retrofit the tank with a sink, like Sink Positives. The cost for black tanks themselves will depend upon capacity,  typically  around $250. Septic systems vary immensely for cost of installation. Variations can depend on location and if they are often compatible with the differing types of terrain.

Permaculture- Composting

Posted on

We’re honored to bring you this guest blog from Tiny SMART House owner and founder – the man, the myth, the legend, Nathan Watson. 

iNTRO TO pERMACULTURE

Everyone has heard the term “Permaculture.” But what is it? The short answer is that it is the utilization of local resources to benefit the local community. Semantics aside, it’s the philosophy of making do with what you have on hand. When there is a surplus, it is redistributed for the greatest benefit to the land and people. Everything has connections that can be utilized. For me permaculture is the process of finding better ways to live. Ingenuity is the corner stone.  

With the resurgence of sustainable living, there seems, to me, to be too much information out there. There are certificate courses available if you are so inclined, but personally I have a more casual outlook on permaculture itself. How do we start the transition to sustainable living? What are some of the things I, as an individual, can do with limited resources? Let’s jump into a few ideas that will reduce negative input and/or create positive output, preferably, both. Once you embark on the road to sustainability, your life will become your project. More than that though, “You” become the project. After all, you are the most important member of the system you live in. You can have a good impact, simply by moving away from conventional ideas. 

Composting 

This is more than using your food scraps or composting toilet to make fertilizer. Compost can be used to build healthier soil, help water retention and even heat your home. Compost for me is anything organic that can’t be fed to animals. Chickens and pigs will eat just about everything.  What’s left is basically, manure, eggshells, coffee grounds, branches and yard clippings and the like. These things need a little time to make them more useful. Healthy compost will have reached a temperature that kills any pathogens and breaks down complex compounds into simpler ones. Regardless what your thoughts are about humanure, there is a use for it everyone can live with. While it is safe, if composted correctly, it can be used to feed fruit trees and for horticulture projects. It can be used to grow plants that attract birds and bees. Compost has been used to heat homes. By using the heat generated from composting to heat air or water, the energy can then be pumped to heat living space. A pile of branches, manure and plant material on top of poly water lines can heat a home. 

I like paper towels. For good or bad, that’s my reality. Those paper towels make great worm beds. Worms help make your plants healthier. Healthier plants produce more and resist pests. Happy plants taste better. Worms attract birds. Birds eat pests. And birds are cool. They are the sound most of us associate with nature. Connections. They are everywhere. Worm casting are key to a lush garden. Worms are pretty easy to grow. They pretty much run on autopilot and you can eat them if you get hungry enough. Or sell them.  

As tiny house living goes, the hardest part has been accomplished. A small living space minimizes energy requirements and materials used to create it. When planning a life like this, outdoor spaces are utilized more and these spaces tend to get more attention. Sit outside, observe nature, plan around the findings from these observations. Make the area nearest your door the most intensive. Mid-size project should be integrated with nature outside that and the farther reaches are minimal care. Slowly adapt your space over time, leaving room for modifications and unforeseen projects. A well thought out project will integrate every resource in the system. A reasonable project will utilize the most plentiful resources first and with time adapt to integrate more and more of them. A simple project is dumping the composting toilet in to a rose garden or building a small wetland gray water system. Some projects will fail or become obsolete or too cumbersome, being replaced with new ones. Just try to help the system work better.  

Any of these ideas can be found in books, articles and the internet. If you’re just curious, working on something or committed to the idea, permaculture is more than a science. It’s a way of living with the natural world. Some people find this idea appealing and some feel it is necessary for their happiness. I am a nomad. I don’t have a piece of property to cultivate. What I do is spread the ideas around and help people develop ideas and projects. All over the world people are moving toward a more sustainable life. There are countless demonstration retreats and farms in every country. If you look you can find one near you. Go look at what people are actually doing and you’ll see healthy people and plants living the way they are meant to. Every project is different and tends to take on the personality of the creator.  A lot can be called life art and are some of the most beautiful places on this planet.
