Summarize this article for a 10 year old
Passive house (German: Passivhaus) is a voluntary standard for energy efficiency in a building, which reduces the building's ecological footprint.[1] Conforming to these standards results in ultra-low energy buildings that require little energy for space heating or cooling.[2][3][4][5][6] A similar standard, MINERGIE-P, is used in Switzerland.[7] Standards are available for residential properties and several office buildings, schools, kindergartens and a supermarket have also been constructed to the standard. The design is not an attachment or supplement to architectural design, but a design process that integrates with architectural design.[8] Although it is generally applied to new buildings, it has also been used for refurbishments.
