  2. Building insulation - Wikipedia

    en.wikipedia.org/wiki/Building_insulation

    By installing insulation, buildings use less energy for heating and cooling and occupants experience less thermal variability. Retrofitting buildings with further insulation is an important climate change mitigation tactic, [1][2] especially when buildings are heated by oil, natural gas, or coal-based electricity.

    R. -value (insulation) The R-value (in K ⋅ m 2/ W) is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction. [3] R-value is the temperature difference per unit of heat flux needed to sustain one unit of ...

  7. Superinsulation - Wikipedia

    en.wikipedia.org/wiki/Superinsulation

    The passivhaus standard combines superinsulation with other techniques and technologies to achieve ultra-low energy use.. Superinsulation is an approach to building design, construction, and retrofitting that dramatically reduces heat loss (and gain) by using much higher insulation levels and airtightness than average.
