| Summary: | Passive houses with three principles of comfort, low energy and economic efficiency started from Germany in 2009. Passive houses must have a heating energy demand of less than 15 kWh/(m²a) per year, and there are currently about 4,000 passive houses certified in Europe. Currently, Korea has begun experimental construction of passive houses from 2005, and it started to introduce it in construction market from 2009. To date, 160 units have been certified, which differs from Europe in that Korea is certified as a passive house up to 50 kWh/(m²a). In order to establish this standard, Passive House Institute Korea (PHIKO) collected and analyzed the data of the completed buildings over the years.
As a result, Korea Passive House standard was newly defined considering the climatic condition (humidity and solar radiation) of Korea and the lifestyle of floor-heating and sitting on that. Of course, these standards are not definitive, and they are still underway, and if more data is accumulated, the standards can change.
