Friday I raced to the prefab modern house, cleaned up, and met with a reporter. Then my family and friends arrived, and honeychile, we trashed the prefab house kit. Saturday we woke up and frantically cleaned up for the Prefab Open House, which was really fun! Thank you all who drove from so far to come visit us in the off grid prefab house kit, STILL with no systems! Then the Prefab Open House was over, and we promptly trashed the house, again. THEN Sunday we woke up and frantically cleaned, again! And a photographer came out. And then we trashed the house! Then I cleaned it again! I. Am. Pooped. It. Was. FUN. : ) We are very grateful to The Ault's Family Farm who not only let us take showers, but sent us back to the prefab passive solar house kit with cartons of gorgeous pullet eggs to give our guests!!! And, why yes, we *did* eat cake! : )
As we mentioned, it's not just about a cool modern, energy efficient prefab house. It's about purposely spec'ing for less systems, for off grid, doing more with less. It's the fun treasure hunt to Make Somethin' Outta Nothin' - note as you look at pictures of the prefab, that almost *everything* has been recycled and reused - from the passing-down of my grandmothers bed, to the bookcase found in a thrift store used and already reused within our own family in four different ways before finding its fifth use in the prefab house. A nice woman from Maryland asked me how we got into "green living." (And she is in wildlife management! She should be giving us advice! : ) ) The simple answer is... we grew up with land, feel connected to it, see the cause and effect in how people treat it. We grew up sailing, so understand the wind and sun and how to use it. We camp, so appreciate bringing this all together to preserve but also shelter and sustain our family, comfortably. Plus supa coolio modern design is really fun on a shoestring. I like the hunt!
Seriously, it just makes sense. Living carefully, purposely, frugally just. makes. sense. And is tons of fun.
Energy Audit #1, today's energy audit of the prefab modern house, is as we're at the "This is the modern house kit + cladding + the homeowner sealing around the windows stage", the second will be once we're "done, finished, kaput, as in done, done, done, done, don't ever want to think about anything construction related for at least another week DONE."
Our mission is to create tight, energy efficient, gorgeous passive solar house kits. I admire rated, certified, even more stringent approaches, like Passive House standards, maybe we'll do this in the future, but we achieve what we want in an energy efficient home while incorporating great modern design on an average, reasonable budget.
Some highly energy efficient homes incorporate two door chambers to prevent temperature loss.
I picture the way I live, and it is just too chaotic and messy to make such an entrance successful. Can you imagine a couple struggling with the stroller, dogs still on the leash, juggling a bag of groceries and a baby on one hip, getting the key in the door lock then screaming to the spouse...
"Quick honey, seal the chamber, we're losing LEED points!"
Obviously if you live in a severe climate, it makes sense. But we're in Normal Rest-o'-Tha-World here.
We're a muddy, raggedy bunch here... why do ya think we're bandits?
You can increase the thickness of the house kit panels, choose even more efficient doors and windows (our casa ti prefab green home is spec'd for Jeld-Wen and our, SIPs house kit with two stories, The R1 Residential, is spec'd for Marvin Integrity), seal it up even tighter... but my focus is on affordable energy efficiency in our prefab green homes, so we chose great solutions that fit within a moderate budget.
The average quote for the casa ti windows is currently about $9,000-$10,500. If you would like to spend more on windows to make 'em nano-crazy-efficient, go for it, we can adjust the shop drawings. But expect the added cost.
We hired energy rater Guy DuBois, of No Energy Loss, to come out and inspect the modern prefab house kit.
These are the notes I jotted down during his cell phone call to me en route from the land. Mr. DuBois will guest blog later this week with more real data, but here are his initial verbal impressions of the still-under-construction, still-not-completely-sealed house kit:
"Well, we certainly smoked up your house quite a bit, there was nowhere for it to go!"
(Copeland's note: Ummmm, I assume he means it was some kind of smoke air test thingy? I hope he didn't mean he smoked in mah house?!?)
Ok, on to Mr. DuBois:
"Those windows - they are worth the money, they were very well sealed."
Copeland's note: Handsome Husband also sealed around the frames... OK FINE I will just stop commenting and just TYPE what he said!
"Your husband did a good job of sealing around the windows... there are two areas he also could look at if he wanted to seal further- along the south eave and that back door threshold.
It is surprisingly tight. I don't know why I say surprising, but I guess I didn't expect it to be so tight, even though I should have."
[Copeland's note: Um, yeah, thanks Mr. DuBois... ; ) OK, OK I'll stop commenting!]
"I'll go back at completion and run more tests. This was a good time to go out there because if there were problems you could address them before everything was closed up.
As you know, it's so tight you really must have mechanical ventilation, which you will be installing (HRV), which is critical in these energy efficient homes. Most homes, most traditionally-built homes, leak willy-nilly so you don't ever have to worry about air quality, but in energy efficient homes like these they're so air-tight that air-exchange is imperative.
I saw very little air leakage... there is some thermal bridging you can address if you want but you certainly won't have a problem heating and maintaining good energy efficiency, that's for sure. How does it compare to a "normal" house? Superior!"
To continue to seal even further, concentrate on the areas where there is lumber vs. SIP (structural insulated panels)- the doorway header, add insulation around wooden framing, and if you're in really severe climates, you could add an exterior seal.
Mr. DuBois makes a good point:
"But you have to consider the climate- maybe if you're in Alaska or really south Florida you would want to consider that, but... we're in Virginia, how much gain will you really get by doing all that?!? You already know that with your off grid systems, comfort will never be an issue.
I will be punching in everything I did today and coming back with some data next week... you're not trying to get this house certified, so this is just more FYI info, but it will be cool to compare today with when you're done at the end of the project."
He also said that the amount of leakage currently (we're still not done sealing) in the prefab SIPs passive solar home is equivalent to about 6 x 6 inches, smaller than a basketball. Handsome Husband is chasing that number, with sealant in hand.
Later, Handsome Husband arrived home, and I had all these pictures and video to look at... and share with you now.
HOUSE KIT ENERGY AUDIT VIDEOS:
Mr. DuBois sets up...
They start do to the smoke test and pressurize the modern house kit. SUDDENLY, a clerestory window pops wide open! It had looked closed, but hadn't been closed totally, which certainly that had also contributed to our loss of temperature this winter at night! It is securely locked now... : )
And then....they freakin' fill mah house up with SMOKE!
Note the comment about the south edge- later they discovered that when the door was installed they didn't put any sealant under that south door. You as a home owner can seal that more if you live in a severe climate area. I knew the windows worked really well for our budget, but am pleased with how impressed he is! : )
NOTE:The next week Handsome Husband discovered they hadn't sealed pipes inside for the audit + we haven't added the foam *around* the foundation, contributing to temperature drop / leakage. Stay tuned for Energy Audit #2!
Check out what it looks like when they crack the door (and how hard it was to open because of the pressurization - because the house kit was so tight!).
"This wraps up the initial test of the house kit. We now know what simple steps we have left to optimize the envelope of the SIPs house, and we look forward to the final testing after construction is (finally) completed. The general goal and idea of the casa ti has passed Mr. DuBois's testing with flying colors, as we already suspected in the prefab house kit's performance over the last few weekends where the design and structure were able to give us relative comfort in a hostile climate.
The great thing about the delays in this project is that we're able to thoroughly test the house kit without further improvements, this allows us to confirm the performance a passive solar house kit built with SIPs."
It's that time of year again, when you collect the photos from the year and send 'em off to the far-flung great-aunts and uncles.
Looking over these months, I enjoyed seeing again our net zero prefab green home take shape. There's still much to do; but even before the interior is completed, the prefab SIPs house can be beautiful with its use of light, open spaces, and special touches.
Here are some pictures of the interior as it has evolved this year...(with a few exterior pics thrown in...)
We will be dragging out a *lot* more (most of it reused, recycled) furniture this month...
It's amazing how you really can make a home out of little recycled elements, and a lot of love and creativity. It is now also clear that my accessory and design elements incorporate... dogs.
Here's an idea: Instead of increasing landfills to accept more waste, how about if we get the construction industry to WASTE LESS?
"The landfill can currently accept a maximum of 900 tons of waste per day. The proposed modifications would allow up to 3,500 tons of waste per day and increase the capacity by about 25 percent to 2.6 million cubic yards."
The majority of the landfill's intake is construction and demolition waste. WHAT? What ever happened to
1. creating less (how about zero?) waste, and
2. re-purposing and reusing materials instead of just demolishing?
"In new construction, you can recycle leftover drywall, concrete, etcetera; there are a lot ways to recycle materials instead of putting it into a landfill. Better yet, don't buy and cut unnecessary materials.
There are standard material sizes. If you work within those dimensions, there is no need to cut or waste material. If there IS waste, often it can be reused on the same site or repurposed for something else. There's a whole section in LEED standards about reduction of construction waste.
Copeland's husband mentioned to me the door landings on their prefab house kit were built from the small pile of leftover wood that they reused for the prefab modern house! Even that pile of wood could have fit into the trunk of their car if they wanted to repurpose it elsewhere.
Do we need to tear down buildings to begin with? How often can we rehab and reuse buildings? Think of Habitat for Humanity's Restore Richmond or Caravati's - often there is someone looking for that exact material you want to throw away!
From a builders standpoint, it's a money-saving, good business decision."
We will begin to have guest bloggers (weren't you tired of listening to me anyhow?), people who know a heck of a lot more than I on the next steps of the prefab SIPs house kit as it goes from a modern house kit shell to a sustainable modern homestead in the years to come.
turning the page on sustainability and the sufficient garden...
Sustainability and landscape go hand in hand, but to really understand sustainability from a livable principal you must put form in the background and set the focus on function. The two do not have to live entirely separately, but the thing that has driven landscape design for centuries must become secondary to to the primary purpose of function. A sustainable landscape does not have to leave beauty out of the picture, but it is there for many more reasons than just aesthetics.
Let’s take green modern kits casa ti as a prototype for understanding the adaptation of the built object to the site rather than the normal process of site adaptation to accommodate the built object. casa ti is a melding of modern living principles with a centuries old notion of living with the land, off the land, and of the land. casa ti is sited in the middle of rural farmland in Virginia.
At first sight, it seems as though there is a modern box sitting in the middle of this soft, rolling earth...still viable earth that is now a repository for a very static looking building. Understanding modern sustainability will turn this perception on it’s ear. casa ti, a prefabricated green modern kit home is actually a very dynamic part of the earth and a living, breathing entity that sustains the land it inhabits. The landscape that surrounds casa ti becomes a fulcrum that allows the exchange between the site, the building and the family that lives on the land.
The past two weeks have been overwhelming, hence the silence, and aside from meetings, we haven't anything new to show regarding our own SIPs prefab house kit. [Now, about the *other* prefab house kits being built... (claps hands over mouth) Ahem, more on these later! : ) ]
Instead, we have spent time over the past weekends exploring Richmond's James River, which we never had access to until we bought a vintage Boston Whaler. It's amazing what a little river access can do for a family! We can now hook up the boat and in 15 minutes be at the river, watching bald eagles, blue heron, turtles and fish with our children.
Our original plan was to visit an artist's studio he built with structural insulated panels (SIP) but we digressed and instead sat outside watching the children play.... enjoyed the day and company of each other while discussing Woodstock documentaries, green living, and off grid net zero systems.
"casa-ti is a remarkable example of how far prefab residential architecture has come. this greenmodernkits kit home is located on 55 acres in a heritage area in the western portion of virginia. the most exciting yet challenging thing about the casa ti project is that it contradicts any idea that the landscape is a stayed design, or an anchor for the architecture. we are taking a very historical site contextually speaking and turning it on its ear...creating a post modern design that connects the home with it’s expansive environs. i think the opportunity to design a functionally sustainable, yet whimsical site plan for casa ti is a true honor and an evolutionary process. we are talking about the first kit / prefab modern home that is completely ‘off-grid’ / fully sustainable in the state of virginia.* this shows that the greenmodernkit home can translate anywhere, in any capacity. it is my job and again, opportunity, to create that threshold between the prefab sustainable home and the environs in which the owners choose to site it. this is a luxury for me. i can take a very simple form of architecture, which has it’s own inherent beauty in that it’s simple, and connect it to it’s site through the landscape architecture. whether it is urban, sub-urban, or farmland, the modern pre-fabricated homes that are greenmodernkit homes do, in fact speak the language of their location. and it’s a language that is very sensitive to the people living in it as well as the environment."
[ *Heather said we're the first off grid prefab in Virginia, I haven't heard of any others, but I don't know for sure if that's true... will research, but no, I haven't heard of any other modern prefabs that are off grid here... ]
Wow, Heather, I'm honored by your words! When Topos originally inquired into what our landscape architecture would be, I laughed and replied, "Um... a bush hogg, Handsome Husband and a shovel?"
I thank Topos immeasurably for giving OUR FAMILY the opportunity, through their experience, to turn an abandoned, briar-filled plot into, one day, a sustainable farm.
So... let's go through it:
Starting with field #1, Topos created a figure 8 access road which allows us to easily navigate the drive, house, and shed while maintaining the field. This eight acre field was previously farmed. By bush hogging it regularly we have been reducing the briars which had cropped up before we bought it, and will start planting cover crops to enrich the soil this fall. Wildlife such as quail will be encouraged through allowing patches to not be mowed but to create the habitat quail, turkey, and rabbits enjoy.
I also envision field #1 being used to grow potatoes and garlic...
Field #2 is downhill from the house kit. Rainwater will easily help irrigate it.
The area around the prefab house is geared for high traffic and fun... more on that in a minute!
Back to Field #2: Being downhill, rainwater will naturally run towards this plot, and if you can look closely Topos has created furrows and a collection area for water- which is the way they used to irrigate fields in times past.
Not only will we be using that existing field for crops but it will also harbor fruit and nut trees, and a berry hedge.
This area is surrounded by woods that had been cut-over twenty-ish years ago. Lots of pine, cedar, but a surprising amount of diversity in the trees- poplar, birch, hickory, walnut...
Ok, let's get to the prefab house kit area:
Pavers made with recycled fly ash for high-traffic areas in poor soil areas
Cisterns for rainwater collection
Baffle (you always wanted to know what a baffle was, didn't you?)
Root Cellar
Terrace for High Traffic Areas
Retention Pool (more on what this does later...)
Blueberry Hedge
Berm to lounge against while watching Casa Blanca projected onto the side of the prefab house like David Day always wanted to do with a bunch o' friends
Last night I went to see Food, Inc. In my opinion the movie did not have much new to say about Big Agribusiness but it was well worth seeing, to see how many key people in government that have determination over our national food policy have previous relationships with companies like Monsanto, as well as reaffirm the fragility consumers have over their food choices.
The panel discussion that followed the movie included friends Lisa Taranto of Tricycle Gardens and Lisa Dearden of The Center For Rural Culture and The Goochland's Farmer's Market. The audience participation was lively- I particularly liked a cardiologist who said, "Everyone complains about the high cost of eating better, but don't understand that the medicine to treat the ailments caused by poor health and not eating well are more expensive. We all need to understand that we, individuals, need to be responsible for our own health."
One question asked repeatedly was "How can we make good food affordable for those that need it most and can't afford it?"
We rely on the grocers, the farmers. We can vote with our purchase dollars, telling these businesses that we, as consumers, want humanely raised, pastured meat, and fresh, local vegetables. But what was not discussed was that not only should you take responsibility for your own personal health (eat well, work out, to prevent sickness and disease), but that each person should have the RIGHT to responsibly grow their own backyard (and front yard) veggies, that each person should have the RIGHT to responsibly have a few laying hens and mini-goats for (here's where I reel it back to economics) AFFORDABLE fresh eggs and milk for their family.
Address affordability, health, passing on a sense of connection to animals and land to our children while providing them exercise: If you have a back yard:
Get some chickens! : )
I promise you, your children will chase and play with those chickens allllllllllllll day long, while teaching them about animals and where their food comes from.
Chickens naturally want to be in the brush, scratching for grubs while being protected from predators. So in your average residential back yard, they will be eating the japanese beetles from underneath your rose bushes, hiding in the acuba, pecking through your ivy. Therefore, their "mess" remains in areas that are not trafficked by the rest of the family.
...If only the dogs behaved so!
Unfortunately, many counties and cities have forbidden responsible urban farming. Did you know that a pair of mini-goats, each about 50 pounds, can provide your family with a gallon of fresh milk a day? Both of my dogs are larger than that. My local zoning says I have have three dogs - so I could have three 200 pound mastiffs - yet won't allow a few laying hens in the same back yard?
This is where we, as consumers, need to not only buy locally, eat well, but tell our local government that it should be everyone's right to be sustainable, to have, if they choose, those affordable, healthy options for their family.
Well, it has been a crazy few weeks. We got my sister married off (and her husband's family is from Seattle so they came in early to spend time with their Virginia family here so it was not just a weekend but a nice time over awhile of the families coming together)... then I went to New York on business for about a week... (really, it was no fun *at all* ; ) ) Memorial Day Weekend appeared out o' nowhere, but finally, we were able to meet with Ron, our wonderful contractor, this weekend to plan the next phase of the prefab house kit: The Inside.
To finish the house, we need financing. The financing we did earlier was to refinance our current home loan because interest rates dropped so much. Now we need to consolidate the *land* loan and finish construction. We're increasing the *land* loan by the amount we need to finish construction since a traditional construction loan in Virginia does not understand or value green building or off grid construction / systems. Once construction is complete and we have a certificate of occupancy, we have been told by mortgage lender of our first house that they will consider refinancing the land *and* house. Because co-op interest rates are higher, Handsome Husband projects that once we have a traditional first mortgage, the monthly expenses will remain the same after the construction is financed. So we will be paying about the same, to do more, after having finished the project!
To get financing, we need to have a quote from our Fabulous Contractor, Ron Bernaldo of Giant Oaks Construction.
To get a quote from Ron, our Fabulous Contractor, my Handsome Husband needs to give Ron details, a list of systems (down to the model number) so that the electrician / plumber can give us an accurate estimate.
To get an estimate, we need to have the interior framing done.
To have the interior framing done, we have to give Ron the customized floor plan. (Yes, people, these house kits are made so you can work with your contractor to make 'em as you want! We didn't change much, just added more room for systems and a nook & cranny for a bookcase...)
If ONLY the rest of the personal decisions we make as a family were as easy as it was erecting the actual house kit! So yesterday Ron was given the floor plan, a list of systems is on its way, and he starts the interior framing next Tuesday.
In the meantime, I hope you enjoy pictures from this weekend's off grid prefab-ulous adventure at the end of this long and boring post.
We had some dear friends out, and it was amazing how *comfortable* the house kit was in the heat. Before, we rarely camped this time of year because the sun beating down on our little 1960's Scotty camper in the field was unbearable. In the house kit, it was breezy, comfortable, filled with natural light yet soothing and cool inside. In the winter, the dogs snuck into our beds; now they flopped, lazily collapsed on the concrete.
When I awoke last night to an unexpected thunderstorm, snuggled in my bed as it rolled, rumbling, in, I reflected how our visit in previous years would have ended first thing in the morning, packing up miserable muddy wet dogs and children in the rain. Instead, we contentedly listened to the rainfall as the children played together indoors while the adults slowly woke with steaming strong coffee.
In the house kit, the light was diffused and off the cement, not the sharp slants of light directly on the concrete as it is in winter. That was the first thing I noticed- that yes, the sun was not warming the floor but had moved higher in the sky, and thus prevented by the overhangs to heat. We opened the windows and let in a wonderful crossbreeze. The difference between lounging comfortably in the house kit to walking into the open field under the unsympathetic sun was palpatable- we all remarked on it.
Another thing I noticed was... how grateful I am I chose polished concrete. SO easy to sweep and keep clean. We also have recycled pallets at the doors which have been extremely useful to curtail the dirt- it looks coolio industrial, is recycled, and provides a great function.
We installed the screens, so we don't have to worry about uninvited animals/insects during the night entering from the open windows, and Handsome Husband and Mr. H stopped by the recycling center and plucked a nice tire to create a tire swing for the kids! We hung it off the old oak that shelters the picnic bench. Which, by the way, I picked up a *second* picnic bench for $5 at a yard sale so we can connect them end-to-end and have a fabulous banquet table for lots of guests.
And speaking of guests... we will have an open house in September!
So, next, we begin the interior framing. We install systems. We survive children out of school for the summer. ; ) AND some big family reunions scheduled... so June coverage might be a little spotty.
Even after the house is done, we continue crop tree release and increasing function-yet-preservation of the land, so that in a few short years we can be there sustainably full time.
P.s. This north middle window that will eventually be my daughter's room? The children discovered how to open it and then jumped from the sand pile into the house kit, in and out, in and out, in and out... hence my thankfulness on choosing the polished concrete, *again.* There must have been twenty times a day I was grateful for the concrete. Ah the spills. Oh the mud. Gee the sand. And the polished concrete took it, and looked gorgeous.
From the beginning, here are my thoughts about the land:
I love the fact we did not have to cut down ONE TREE for the home site.
However, we are big believers in crop tree release to help the woods become healthy. What that means, in short, is removing weed/competing trees to let the native, desirable trees grow strong and healthy. Along the field we have a mixture of poplar, hickory, oaks, walnut... mixed in with cedar, red bud, pine, a few dogwoods and... non-native evil ghetto palms! Ghetto palms, I'm out to get you!
The 8 acre field can be rotated with
cover crops of warm season grasses that encourage the quail habitat (as well as leaving strips here & there in the fields, and other quail / wildlife management practices)
potatoes, garlic, onions: With friends we can plant the field, then harvest it together, keeping enough for our families and donating the rest to the Society of St. Andrews. I mean, why glean (although I do look forward to doing that with my friend Peggy, what fun combined with hard work on a gorgeous weekend!) when you could actually plant a field for hunger? (Also note: store bought potatoes have one of the biggest carbon footprints as they often travel quite far to reach the consumer. They're so easy to grow, try growing your own in your back yard!)
There is a smaller field downhill from the home site we could irrigate with rainwater... we've tossed around ideas of growing some kind of crop there, like asparagus... but the reality is that as it is much deeper in the woods it will be much more accessible to wildlife... but it's something to think about...
I would love a root cellar in which to store food.
...and, I admit, we have a hankering for mid-century coolio functional cooking grills- purposeful practicality with kickin' design. YES I realize this is a murky area, in which I struggle. Half o' me is survivalist (heck my family has survived here for hundreds of years), half of me is forward thinkin' design, and half (fine I never said I was good at math!) o' me wants a third option from the solar cooker and propane marine stove. I mean, if the weed tree is felled, why not use it? (Or not? Considering.)
Handsome Husband and the casa ti green building architect, David Day thought it would be plenty fun to have our friends hang on the slope next to the east side of the house in the evening and project old movies onto that north-east side of the house. They were even tossing around words like, "amphitheater." We'll see. They're such romantics. Which is why I love 'em. Which is why they're both more talented than I. : )
We've already planted apple trees around the shed, and I was pleased to see they are all in bloom and healthy! In a few years we can invite friends over to pick apples!
Now I also must remind myself that we are on a STRICT BUDGET. So maybe most of these ideas will not happen for years. But in the meantime, here are a BUNCH of land pictures, so that the Virginia landscape architect Heather Barber can get a better feel of the entry, field, and area surrounding the modern house kit. I commented on many of the photos, so if there is something that interests you, click on it to see it larger, and with commentary.
We also met with Ron Bernaldo, also known as The Most Fabulous Contractor In The History of the World about our next steps. I can not re-iterate enough how critical having a knowledgeable, experienced contractor has been to the success of our house kit completion. The house kit itself erected easily; but the decisions we had to make as consumers, making the modern off grid house kit "our own"- could not have been affordably or successfully achieved without a contractor like Ron.
Regarding our green building progress, as I mentioned we start again framing the interior, then move on to solar and rainwater collection integration. And THEN we move to interior design of the house kit. Married to a fellow design enthusiast, living our role as house building consumers, I suspect there *might* be design fights ahead.
The first hint came when Handsome Husband nailed up some old sconces. Yes, they do help light the interior of the unfinished SIPs - exposed house kit, but... um... Fortunately they dribbled wax onto his pristine-just-polished concrete floor so I suspect that will be that. But we shall see... never underestimate Handsome Husband.
So maybe I should start a new blog category, called, "design fight" just in case...
In the meantime, here are a few more pictures of the zero energy modern house, it was a *lovely* weekend on the land!
