There is a type of home that does not require heating in winter or air conditioning in summer. Have you heard of them? They are called passive houses and the name already applies to a large number of projects that are committed to energy efficiency as an essential feature of the home from the moment it starts to be built.
To achieve this, experts developing passive house technologies need to focus on three essential features:
- Controlled ventilation systems that ensure effective maintenance of the ideal temperature, with the correct recovery of cold and heat where necessary.
- The materials used in the doors, windows and walls of the house.
- The re-use of traditional household devices that can be used to generate heat.
In these passives houses the temperature is usually about 20ºC, although it can vary depending on the location and the geography of the surrounding area. However, this temperature is maintained without the need for electric or gas devices that have been purchased in order to acclimatise the building.
Because no energy is used to maintain the temperature, it can focus on the other day-to-day tasks to be done in the home. This is how passive homes become real models of energy efficiency that inspire other experts to create materials that are of better thermal quality and are more efficient.
