Earthships

I prefer passive, I'd rather stay away from any mechanisms, I like the idea of lots of windows, ground heat last I checked involved drilling pretty deep, heard about some minisplits, havent really read about it, honestly kindof defies the point I am trying to get away from depending on an apliance for heat regardless of type and cost, could have gotten a wood burner just as well.
pv not so sure about that again we're back to 3 hours a day, wind sounds more apealing,
HRV read briefly about it

I really liked the idea of a sunroom and the gray watter planters that was another reason for it, I'm quite into getting plants started, hardly have any windows in my curent house.

again keep in mind this was a worst case scenario we were adding up, should look at the whole season see if I break even or so, thermal mass will play a role too as that 3 ft floor slowly gains heat since summer solstice, so hey there may be days where the windows rate negative, that is where the thermall mass comes in, the tripples never would be negative thou I have some doubts about the R10 and even if that is so in a laboratory, gas leaks over time, windows get damaged during transport or after install, I prefer simple things, a plain double pane will still be R2 20 years later it was filled with air so what if it leaks

this is a bummer but I'd rather realise it now

 

So if were to consider the buffer zone at half the temp gradient 26.5*5/9=14.7C

2.8*14.7=41.2wh*24=989wday*31

31kwh loss for January compared to the 25kwh/January for triple panes only

Crap, he had a point I guess, one wall of triples is better than 2 doubles and the buffer zone can actually be living space, son of a ……………….. guess I have to get a quote now just for gigs

Granted gain will differ too I think 1500 per day for triples last ve figured it, 46.5kwper januarry/sqmter

Versus say 1800*31=55.8kw

55.8-31=24.8

46.5-25=21.5 this is a bit odd total gain is less doesn’t make much sense yet it keeps more area heated I guess that’s another point where the R10 double dips, can achieve more with less heat

Actually if I were to try and keep the living space at 70F 31kwh/sqm would leak into the sunroom and than another 31kwh outside, back to the 60kwh earlier determined in other words the buffer appears as a perfect conductor, there is something wrong with the physics if not the math either way the gain is less.

Still if the net works out to be about 5kw/january/sqmeter that could again be translated into a total R value, considering the rest of the structure is R50 except roof R 100 I would assume heating needs would be minimal in other words such a setup wont maintain 70Funassisted, 1 row of triples may produce a net that compensates for the rest of the losses, even in january, so frying in januarry is out of the question wonder how the other months would do.

I guess this is where the whole modeling comes into play, it gets complicated thou say I figured the total heat loss for the year equals the total solar gain and I do have enough thermal mass to store it all, would that do the trick?

In some sense I am jealous of other climates, but than I look at that pic you posted of the desert view, not sure what I would do with myself out there

 

I honestly dont believe in PV or renewables for that matter the way it is done comercially, that is a topic for another conversation, but just a peak a pannel 18v open charges a 12v battery inverter to 110v to run a led bulb at 3.5v through a inbuild ps, all this stuff is expensive and problematic.
my version, i pv module makes 0.5v, 1nstead of pairing them to make 18 v use 10 in series for 5 v to charge a lifepo4 to a nominal 3.6v and run your lights, same concept for each apliance make a pannel to charge your laptop, one to run your tv, which also is low voltage DC it has an inbuilt PS to get its power down from 110, that stuff I know more about than this, but that is the concept for electricity for this house, each apliance will have its own voltage, for example they make 24v dc fridges, you can charge your drill in that outlet but not plug in a light, decentralisation

 

Welcome to the Efficient Windows Collaborative

 

I think its Anualy, it's supposed to be 10 % conventional housing 1200kw/m2a I think
if you look at the site I mentioned above at some point it says in multiple panes the middle ones can be suspended thin film, that takes the weight out of the equasion

 

in passiv haus terms, I dont believe they count where the energy comes from just total energy used. there are a few tweeks to your math if you want to campare apples per apples,
at the same time remember this is Europe standards I grew up there it's very simmilar with Michigan some places is worst, you get into the scandinavia might as well compare ir to Red Deer, Alberta.

we just found out it is much simpler to build a passive solar house in New Mexico than Michigan, and a Global model Earthship wont do well at all up here, same principle aplies, a german standard passiv house would require much less energy in your town, matter of fact they would probably skimp out on some of the insulation, from what I gathered althow you may see the same lows at night as up here, in your area those lows are more like short spikes before morning, we see these lows coming in in november and they are here to stay till spring, same with Germany, probably part of the reason plain double panes are fine in your area as you may get more prolonged sunshine and daily highs are much higher than up here for example what are your HDD for januarry compared to mine pushing 1700

 

I get what you are saying but that still looks like a dry sunny winter to me, its not much different here this time of the year except it is all covered in hte white stuff, but I have a feeling your summers are looking much like your winters, as soon as march hits here it is all lush, for years I planned on moving south, I grew up at about the same latitude in Europe always been in the north and sick of the cold especially mid winter, I've come to realize how important the winter cold is the the Ecosystem, you get further south you start encountering mutant moskitoes reptiles, I'd rather take on a bear or a pack of wolfes, thou they are not arround here, further north outside of the cities maybe, part of the reason for this project is because I realised there is no place I'd rather be and instead of trying to escape the winters and trade off for rattle snakes, I best figure out a better way to deal with it.

so I ran some numbers had to look at it side by side, I've come to realize double panes is a bad Idea and too much SHGC could be an issue in the summer, while it can efectively be compensated by better insullaion value, also since I figured a tripple pane doesn't necessarily imply 3 panes of glass, explains how you can achive a SHGC of less than 0.85 per pane, and not weigh significantly more than a double, so I figured a fictive quadrupple clear pane with the 2 outer galzing glass at 0.85 and the 2 inner light plastic film at 0.9 shgc for a total theoretical value of 0.585225 SHGC, not bad, when debating the angle vertical versus 65 degree ( perlendicular to winter solstice noon sun angle ) , I loose 5 kw in november, 4 in december, 4 kw in januarry, 7 in februarry, that is unfortunate but I also loose 26kw in may, 25 in june, 25 in july, 21 in august where solar radiation is actually unwanted, so vertical it is, done settled not talking about it, plus it is so much easier to build and less prone to issues.

that beeing said since a quadruple pane will only weigh whatever the plastic some corkboards and extra seal adds up to, screw it why not, there are plenty of local window makers, I am sure I CAN MAKE SOMETHING HAPPEN WITHOUT HAVING TO IMPORT THEM FROM gERMANY AND SPEND a small fortune.
now where was that post Corwin figured the R values? BRB

 

there it is so R0.17 + 0.15+0.68(first space)+0.1 ( ?first plastic )+0.68 ( SECOND ) +0.1 +0.68 (third ) +0.15 +0.68 inside air a theoretical total R3.39 for air filled, now I read that Argon has half the conductance of air somewhere.
that would mean 1/1.36, if argon filled would total 5.43 R, I GET IT NOW, once you get into xenon and such I can see how R values can go up and still have decent SHGC, initially I thought it was a smart sales pitch not like I havent heard of snake oil before, so such a window if properly built will have an initial R value of 5.43 which eventually will leak down to 3.39, not sure how bad that is in michigan heard NM is worst high altidude dry low pressure, this could work

 

I do but look at my drawing at high summer solstice the sun will shine the Green house only a measly 27kwh for the month of june, considerably less than 41 in februarry to the back of the house, that area can be wide open at that time , whatever heat may convect to the living space the mass may absorb and account for the HDD at night, should work out pretty good I should be able to modulate it beyound this point, plus the grey watter planters help, I haven't bothered much with that yet but it is in the plan I like plants and I keep a garden just so my boy doesnt grow up thinking vegies grow in suppermarkets, the gray watter planters help in a few ways, the plans absorb the extra sunlight in the summer, the warm tub watter stays indoors longer in the winter, think about it, I know most have a hard time acepting that concept but like everything else if properly done could work out, not to mention in passiv hause they use the HEV for ventilation and fresh air, having lots of plants you could seal up the house in the winter and hot wory as much about oxigen depravation without an HEV.
like I said an Earthship may not work for michigan but there are some good concepts there

 

Wth R 10 how?
