  2. Building insulation - Wikipedia

    en.wikipedia.org/wiki/Building_insulation

    And the standard has some mandatory thermal insulation requirements. [13] All thermal insulation requirements in ASHRAE 90.1 are divided by the climate zone, it means that the amount of insulation needed for a building is determined by which climate zone the building locates. The thermal insulation requirements are shown as R-value and ...

  3. Shallow foundation - Wikipedia

    en.wikipedia.org/wiki/Shallow_foundation

    The slab can be decoupled from ground temperatures by insulation, with the concrete poured directly over insulation (for example, extruded polystyrene foam panels), or heating provisions (such as hydronic heating) can be built into the slab. Slab-on-grade foundations should not be used in areas with expansive clay soil.

  4. ASHRAE 90.1 - Wikipedia

    en.wikipedia.org/wiki/ASHRAE_90.1

    ANSI/ASHRAE/IES Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings is an American National Standards Institute (ANSI) standard published by ASHRAE and jointly sponsored by the Illuminating Engineering Society (IES) that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings (i.e. single-family homes ...

  5. Thermal transmittance - Wikipedia

    en.wikipedia.org/wiki/Thermal_transmittance

    The average thermal insulance of the "bridged" layer depends upon the fraction of the area taken up by the mortar in comparison with the fraction of the area taken up by the light concrete blocks. To calculate thermal transmittance when there are "bridging" mortar joints it is necessary to calculate two quantities, known as R max and R min .

    en.wikipedia.org/wiki/Building_code

    Requirements for earthquake (seismic code), hurricane, flood, and tsunami resistance, especially in disaster prone areas or for very large buildings where a failure would be catastrophic [citation needed] Requirements for specific building uses (for example, storage of flammable substances, or housing a large number of people)

  7. Waffle slab foundation - Wikipedia

    en.wikipedia.org/wiki/Waffle_slab_foundation

    Waffle slab foundations adhere to International Building Code requirements. By 2008, most states put into effect the changes adopted in the 2006 IBC and, in regards to foundations, the on-grade mat foundation has become a more attractive design because, as an engineered system, it already accommodates the 2008 design recommendations, and required no major modifications to bring it into compliance.

  8. Concrete slab - Wikipedia

    en.wikipedia.org/wiki/Concrete_slab

    Without insulation, concrete slabs cast directly on the ground can cause a significant amount of extraneous energy transfer by conduction, resulting in either lost heat or unwanted heat. In modern construction, concrete slabs are usually cast above a layer of insulation such as expanded polystyrene , and the slab may contain underfloor heating ...

  9. Insulating concrete form - Wikipedia

    en.wikipedia.org/wiki/Insulating_concrete_form

    The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. [citation needed] Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high by 48 inches long with a tongue-and-groove interlock, metal ties, and a waffle ...
