What is a passive house or passive house? These are homes that have no energy consumption. Are environmentally to finance a friendly and have amazing designs. These types of homes have the ability to be self-sufficient from an energy point of view and, in addition, they do not generate emissions . They have their own electrical power systems that have the ability to operate autonomously. There are different models of self-sufficient homes, passive houses are one of them. To be more specific, it is a certification that certifies that the house meets certain environmental standards, regarding energy consumption and design. The origin of the Passive House concept emerg and develop in Germany during the s and was fund by the German state of Hesse . However, the first building of this type was built in , also in Germany.
The principles of a passive house

Windows: they must have windows with high Indonesia Phone Number Data thermal performance. Ventilation: they have mechanical ventilation with heat recovery. This takes advantage of the indoor air with the aim of heating or cooling the clean air that enters from outside when the home is ventilat. Airtightness: the objective is to block air infiltrations and make the most of the previous point. Thermal bridges: there should be no thermal bridges, these are the points of the façade that transmit the most heat or cold . For example, the metal in the windows , which will cause the home to heat up or cool down when it should not. These are the five key points that must be met to access the passive house certification. On the other hand, other points that will be assess are exterior solar protection, the use of renewable energy as a primary source of consumption or heating, cooling and lighting systems installations.
What are the requirements for passive houses?
The principles mention above also imply a series of numerical requirements regarding energy consumption. Fundamentally, a passive house must have a total energy demand of. kWH/ma, this must include the use of electrical Switzerland Phone Number List appliances. However, there are also other criteria: The heating and cooling demand less than kWh/Ma in each section (heat and cold). A primary energy demand of less than kWh/ma , this includes heating, hot water and electricity. A tightness of less than air changes per hour. Is it convenient to build a passive house? Having a passive house will give you the possibility of saving on energy and. At the same time, being respectful of the environment.
