Passive architecture is primarily the way of saving energy in buildings, which does not depend on its own energy consumption, but entirely through the design of the shape of the room, the building envelope, the building materials and the structure of the building itself. For example, the use of shading, wall insulation, natural ventilation and other measures to reduce the indoor temperature in hot areas.

Passive solar buildings use the thermal energy provided by solar energy indoors, do not require mechanical devices to provide energy, and rely only on natural heat transfer through conduction, convection, and radiation. In addition, the building's layout, interior and exterior design, and material selection efficiently capture, shop, and distribute solar energy, which increases the temperature and light in the building. Greenhouses and solar water heaters are widely used and effectively utilise the principle of passive solar design.

Architectural concept of the passive house:

First, adapt measures to local conditions

The concept of passive houses can be applied anywhere in the world, and passive houses can be built in both cold and warm regions, although the basic approach is the same. Depending on the local climatic conditions, the amount of building materials used in the house will vary. In cold areas, it is about the thickness of the wall, the thickness of the insulation layer. In hot areas, it is more about cooling methods such as shading and window ventilation to ensure a comfortable indoor climate in the summer. The individual characteristics of each passive house are optimised according to local climatic conditions.

Second, more comfortable and more energy-saving

China stipulates that buildings south of the Yangtze River are not heated, which greatly saves energy, but people's living environment is not very comfortable, frostbite is more common, and passive houses pursue a very comfortable living environment under low energy consumption conditions. Thermal insulation windows, thermal insulation enclosures, heat recovery devices are the main components of passive houses, from the outside, it is no different from general buildings, so passive houses are only a standard, not a process method.

"Environmental protection" has become an important issue that everyone and every company should care about. More and more environmentally friendly buildings come into people's eyes.With the vision of "smart energy and low-carbon earth", Foxtheon Energy hopes to create a low-carbon, green and ecological environment together with customers from all over the world.
