Aircrete and earth-berming

  • Workshop Instructor

    @ignacio-dhome wanting to keep the bury your hobbit home topic alive as I see it as very beneficial to Us builders. Something that we should all consider is that aircrete has insulative properties but very little thermal mass, meaning it only stays warm or cold if you are expending energy. Thermal mass is what buffers the fluctuations in temperatures. EXAMPLE: Once it is heated it stays warm longer. The cold outside penetrates the structure more slowly because it has to get through the thermal mass to reach the interior. WIkIPEDIA: "In building design, thermal mass is a property of the mass of a building which enables it to store heat, providing "inertia" against temperature fluctuations." I feel that the most energy efficient dome is to bury it. The shape is also perfect for this application! Any thoughts?

  • This is an important thread. It would be great to get the input of some qualified engineers on this.
