4 principles for building more energy efficient houses

[@chrisk7118]

In our architecture studies at uni, they're now advising us against "proofing" or creating air tight buildings but instead encouraging to build with breathable insulation like hempcrete that also have good thermal properties.

I was wondering about straw bale, which would be in somewhere in hemp ballpark. My understanding is that a "breathable" well insulated material should prevent large heat loss. But active ventilation seems just matter of common sense either way.

It's better for your health, if anything. And more reliable, not dependent on electronic and mechanical parts.

Black & Yellow, are you AnCap like me? Or you just like those colors?

[@dieuhoquang1]

Valuable knowledge! Thank you for educating us!

Looks like Barry built one of Aircrete Harrys homes. Not poking holes in the structure for cables and pipes will also keep the heat in. Domes are more likely to have fewer draughts

Great video on the basic principles of building design.

Now all we need is prefab, insulated, air tight geodesic dome panels :D edit: with a high thermal mass

How will we get supplies with a collapsing global supply chain.🤔

[@VeeDeChantilly]

I used a dehumidifier, but am working on on that is solid state, the electromagnetic future is a no go with technology.🧐

There are a lot of issues you didn't mention like thermal lag from infer red radiation from sun. As the sun crosses the sky it embarks energy into your structure beginning from the time it crosses the horizon, as it sets all the mass of your structure now releases that energy in the form of heat and infer red radiation. This is a very big part of your cooling load. With this being said, a big part of your structures design must incorporate reflectivity of the building envelope, many large commercial buildings use reflective roofing for this very reason. additionally there are very few places on Earth with "perfect climates" so you must consider your environmental control systems and that opens a whole world of building considerations. Heating; what type of heat, heat pump or boilers, warm air furnaces etc. Cooling; what type, again heat pump , high SEER DX, ECH (evaporative cooling humidification), absorption with chilled water, ect All these issues you bring up can also be used to control the environment inside the home, for example in hot desert climates they build homes with high amounts of "thermal mass" so as to slow the uptake of thermal energy and slowly release it at night passively tempering the extreme changes in temperature. OH, and they do make residential sized Absorption chillers I have worked on them, they come 5 ton increments and must be placed away from the home as they use ammonia and can smell like piss. They work awesome and last for 30 years or more and ammonia breaks down into nitrogen in the environment so there is no greenhouse potential or ozone depleting potential, only fertilizer potential.

When it comes to the heating effects of the Sun, even if completely ignored by climate science, the crucial aspect becomes building orientation. On the northern hemisphere, I would say the smart thing to do is to have the longer side of the building pointing down south as well as having no windows on the western side. I would also venture to say that having some windows on the east side makes the perfect area for a bedroom, allowing you to sync your cycles with the sun, for maximum benefit. North, the cool, side can probably do without any windows at all. Especially if the building is relatively long and narrow, in which case I'd go crazy with windows on the south side.

Thermal mass is of course also used in cold climates, except trapping heat from the inside in winter for release during the night. In the north, we use massive wooden structures and wood fibre insulation, with walls up to 50 cm thick.

i was surprised to find neither triangulation nor shape among these matters. of course, defining what are the 'most important' aspects of something always leaves out very many other matters. in my mind however, given the principles of structure and shape provided by synergetics, i would put those two before the ones you brought up, will being intrinsically intertwined with all. having said that, omnitriangulation and a good choice of basic shape for any given situation would be my starting point. personally, as a well balanced place of departure, i tend to use the eighteyes mostly (one might know its greek nickname 'octahedron') as it allows for easy frequency fractality not just on the membrane, but also the interior, giving easy options of organic subsystems like rooms and such. also it has substantially less need of members involved compared to both the (triangulated) 'cube' as well as the geodome favorite dozeneighteyes ('icosahedron'), which is a great choice for the overall enveloping membrane due to its large quantumvolume which is even at onefrequency oneandahalf dozen quanta (plus some golden ratio fraction). and yet, the eighteyes has a larger quantumvolume of four compared to the current 'commonsense' box with its quantumvolume of three. it embodies four hexagonal planes within it, a whole vector equilibrium sphere embraced by it. much more to be said, some can be found in my videos... peace struppi

Modern home design is throw away, to design for the near future half of my duration of the GSM roughly 25 years according to pierce Corbin the astrophysics in your country.🧐

I do not agree that when increasing the size of a dome, the thickness of insulation should also be increased. On the contrary, as the size of the dome increases, the surface area of the outer walls relative to the volume of air inside becomes smaller, which means that heat losses decrease. The thermal inertia of the building increases. The larger the dome, the less insulation can be used.

Humidity, humidity, humidity 🤔

Not "feel you need", what you need.🤨

[@That1ufo]

Will you be installing a HRMV in your cave?...

[@VeeDeChantilly]

I am going MicroHomes 4'x8' to 8'x12' it's the only way to survive to coming cold from the Grand Solar Minimum.⛈️🌀🌡️.
