Looking for modern methods of house construction, one can easily come across mentions of passive houses, which have only been built in Poland for about 30 years. About it  <\/span><b>What is a passive house<\/b><span style=\"font-weight: 400;\"> and what benefits are achieved after its construction, you can learn from this article.<\/span><\/p>\n<h2><b>What is a passive house and what are its characteristics?<\/b><\/h2>\n<p><b>Passive houses<\/b><span style=\"font-weight: 400;\">  are built with the latest architectural art to optimize energy requirements. The main characteristic here is the ideal thermal insulation of the building and maximum<\/span> <span style=\"font-weight: 400;\">tightness<\/span><span style=\"font-weight: 400;\">, so that the heat generated inside it largely stays inside.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For this reason <\/span><b>passive house<\/b><span style=\"font-weight: 400;\">  is designed in a specific way, with benefits and savings in mind. Places such as the rooms, living room and kitchen, occupy the south side of the building, because it is this side that has a high level of sunlight during the day.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Very often over a significant area, are used<\/span> <span style=\"font-weight: 400;\">glazing<\/span><span style=\"font-weight: 400;\">, including skylight windows. It is not uncommon for them to occupy the entire south wall. On the northern part of the house, on the other hand, any windows are rarely included due to the highest heat loss in this area. For this reason, the north side is dedicated to low-use rooms, such as the garage, utility room or bathroom.<\/span><\/p>\n<h2><b>What requirements must be met to call a passive house?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">So that no one is in doubt <\/span><b>what a passive house is<\/b><span style=\"font-weight: 400;\">, the definition of this type of building is strictly defined and indicates a specific type of building that uses technological solutions to reduce heating and energy demand.
