Dear Readers,
The Clivus Multrum composting toilet is kinda cool in that its name gives the bases of how it works in two words. ‘Clivus’ is Latin for ‘incline,’ and ‘multrum’ is Swedish for ‘compost room.’ And, in essence, the Clivus Multrum composting toilet is a toilet (basically a hole) that lets waste fall into an inclined composting room. Bam. Boom. Blog is basically done.
Ha! Kidding. To give justice to the simplistic yet holistically functional toilet system, it deserves a slightly more in-depth explanation. I promise, this will be simpler than the blog about wastewater treatment facilities…
Their toilets are much more sophisticated looking than a dark, deep hole you squat or stand over. They actually look like a real toilet! Some even use a small amount of foamy, soapy water (no more than 6 ounces) to clean the bowl when you use the flush mechanism…it’s like you would never know that you just sat on top of, and contributed to, compost.
When you donate your waste as tribute to earth fertilizer, it falls down into that inclined chamber. This incline is super important: it is what keeps the urine and the poop from being one, large, smelly, conglomeration. Gravity forces the urine to filtrate downward through the solid wastes, allowing the solid waste to remain dry (and unsmelly). However, when the urine gets to the bottom of the chamber…it is no longer urine…like a butterfly, the caterpillar has gone through metamorphosis!
Wanna know the secret to changing your urine to something else (maybe not necessarily as pretty as a butterfly…)? I sure did…

Dear Readers,
Our bodies need nutrients to survive. As we consume, we produce waste. This waste is processed. Occasionally, the processed poop ends up as fertilizer and provides nutrients to our nutrients. We then consume said fertilized nutrients…and set them free again! ‘Tis more than the Cycle of Poop. In truth (a deeper more philosophical existential sense…), it is the cycle of life~ where every living being, plant to animal, has a purpose…and even its demise results in a form of rebirth and a giving of life to another. Poop has a Purpose.
In a much more scientific and detailed manner, I am now going to explain to you, dear readers, the step by step processes for how city people take care of their waste (Centralized Wastewater Collection and Treatment) and how country folk take care of their waste (Decentralized Wastewater Collection and Treatment). I will attempt to keep it concise and organized (and all existential crises excluded)…as cleaning poop can be a messy endeavor.

One look at the “unfolding module process diagram” or the “sketched section of folding roof” may result in some gawking, coffee-spitting, guffaws, and perhaps even the closing of this blog. All understandable!
If you have, however, continued to read this blog despite the drool that dripped from your gapping, gawking mouth…and despite the coffee that is now splattered on your screen and maybe keyboard…and despite the awkward stares you received from your side-splitting guffaws…thanks! We are crazy, we know.
So, here is a quick, simplified explanation as to some of the gibberish we’ve got running around in our brains…
Axonometric Sketch of Home
Our home will by no means be a ‘tiny’ home, but it will be a rather small-ish home! It will be 36’ long by 26’ wide on its first floor. The loft space will be about 23’ by 16’ and go above only the bedroom, bathroom, and mudroom areas. The total square footage is estimated to be about 1,304 square feet.
As you can see in the axonometric sketch (such a big word…) we really want to incorporate a high usage of windows…perhaps too many. But that fact is to be soon determined as we currently are also undergoing some cost analyses. All windows would have to have high R-values and be made by a Passive House certified window manufacturer- which also adds to the immediate price tag.
The skylights would illuminate the loft space, bedrooms, and the back section of the ‘great room’ (‘great room’ just sounds so pompous…). We would use what are called ‘solar tubes’ to bring natural light into the bathroom and mudroom area. Solar tubes are neat in that they are literally a tube in which the entering sunlight bounces around before it fills the larger living space, thereby creating a more even distribution of light.
Our home will be small. And depending on how many children we have, it is only going to get smaller. The ‘window walls’ you see at the front of the ‘great room’ are not stationary, allowing our small space to get larger. They can fold to allow the home to be made almost entirely open to the outdoors. The windows above the sink and kitchen area will also be foldable- thereby creating an open bar to the deck outside. A great example of how these guys work is to take a look at Zola’s “BreezePanel Folding Walls” (William drools everytime he watches the video).

In many relationships there comes a time when things get, well…boring. You and your spouse have a routine, and it works. All in all, in a day, things get done while there still exists room for some excitement. You love them, they love you, life is moving forward. It is all a happy kind of ‘mhm.’ Well, William and I decided to spice things up a bit.
We did an experiment.
For 24 hours we measured the exact amount of water we used…washing our hands, brushing our teeth, doing the dishes, laundry, flushing the toilet…it was enlightening! I highly recommend it for any couple who finds themselves in a state of blissful ‘mhm.’
But in all seriousness, we wanted to know what our daily water usage was so that we can accurately size our Rainwater Pillow to fulfill all of our H2O necessities. Beginning at 12 am on a Monday morning when both of us had the opportunity to stay home all day, William and I diligently recorded the amount of water we used when we…..
Flushed the toilet
Washed our hands
Brushed our teeth
Did a load of laundry
Did dishes
Gave water to the chickens and dogs
Grabbed a glass of water to drink or cook with
Took a shower

Dear Readers,
In addition to our future home, The Seed, being designed upon pins and with super thick, crazy well-sealed walls, we want all of the water that we use to be gathered from precipitation and stored in a pillow. This pillow will be stored within our building envelope (so that it is insulated) and underneath our floor. Imagine a giant waterbed in your basement that’s purpose is to provide you with showers and clean drinking water. That’s it.
The rainwater collection system we intend to use is called The Original Rainwater Pillow, created and sold by a gentleman named Jim Harrington. Based in Georgia, he was inspired to develop the rainwater pillow in 2008 during a period of intense drought in his area. Six years later, in 2014, his Original Rainwater Pillow won the U.S. Green Building Council’s (USGBC) Best of Building award for Best Product for Water Efficiency! We are excited to test out the Original Rainwater Pillow in The Seed…but first, how does it work??
How it works:
The Pillow tanks are specifically built horizontally to fit into ‘wasted spaces.’ Think crawl spaces, under decks or porches, basements…that way, the need for excavation for cisterns or a giant tank in the yard is eliminated. And what is additionally so genius about the Pillows, is that they are relatively easy to install- like a deflated air mattress, they are easy to transport and lighter to move around (which is wonderful for prefabrication mind-sets). We intend to keep our Pillow within the thermally controlled building envelope of our home: above the pins and right below our floor.
Rainwater harvesting all begins with rain and a roof. Your roof is kind of like your ‘rain catcher’…the larger the square footage that your roof covers, the more potential you have for more water. As the rain runs from your roof to the gutter system, it will travel to your downspouts and then go through a pre-filter. The pre-filter is intentionally ‘coarse.’ It allows water to move quickly through it during heavy downpours, while simultaneously separating leaves or other large debris.

Dear Readers,
William and I had the opportunity to listen in on a webinar provided by the Passive House Institute of the United States (PHIUS) on limiting embodied carbon in buildings: “Spaghetti Carbon-Era: Disentangling Operational and Embodied Carbon.” Admittedly, I just got the pun of the title…which is all the more humorous if you were to have seen their intro presenting page being that of pasta in a white sauce with bacon.
This seminar was very helpful in reiterating the importance of taking a holistically sustainable approach in home building and living. Not only should the home be environmentally friendly and energy efficient during its usage, but also in its construction and sourcing of materials. The ‘environmentally friendliness’ here is measured by the amount of carbon a home is responsible for emitting. PHIUS standards make a home accountable for its carbon footprint in its operation alone: as in, how much energy the home needs to function once it is already built. This they call “operational carbon” or, “OCO2e.” In the webinar, they expressed that the home has an even larger carbon footprint when its “embodied carbon” or, “ECO2e” is taken into account. Embodied carbon is the amount of carbon that is emitted in the overall construction of the home: from the harvesting, manufacturing, and transportation processes of all of the home’s required building materials. That pink fluffy fiberglass insulation and wooden studs and concrete foundation and drywall has to be made out of something and transported from somewhere…all of the materials have their own carbon footprints which then contribute to the home’s overall embodied carbon.
Two of the presenters, Ilka Cassidy and Steve Hessler, founded a business called “Holzraum System, LLC.” Within their business, they did their own study of how much of a home’s carbon footprint is operational and how much of it is embodied. They used five different homes as case studies.
Home One: built to meet 2009 building code
Home Two: built to meet 2009 building code with high performance systems
Home Three: built to meet Passive House standards, but with a high usage of foam
Home Four: built to meet Passive House standards, but with a low usage of foam
Home Five: built to meet Passive House standards, but with no foam.
