Passive buildings are indoor thermal energy provided by solar energy, do not need any mechanical equipment to provide energy, and rely solely on natural heat transfer by conduction, convection and radiation. In addition, solar energy is effectively collected, stored and distributed through the arrangement, the inner and outer construction and the material selection of the building, so that the temperature and the light of the building are improved.
The solar energy self-regulation is realized by utilizing external energy solar energy, so that the solar energy source can be fully utilized, and the requirements of building on warm in winter and cool in summer are met. The passive building collects and absorbs solar heat energy through the building orientation, so that a warm-keeping effect is achieved; the reasonable layout and the internal space of the building are utilized to strengthen the air convection, so that the indoor temperature is reduced; the energy-saving environment-friendly material is utilized to store solar heat energy, which is beneficial to energy conversion.
The summer cooling and winter heating of passive buildings are contradictory and mutually adaptive relations. The building is required to obtain solar heat to the greatest extent in winter heating, the reduction of ventilation to indoor temperature is reduced, heat loss is reduced to the minimum degree, heat is properly stored, the solar heat entering the room is required to be reduced to the minimum degree in summer cooling, the heat dissipation capacity is improved, and the heat is properly stored, meanwhile, the influence of ventilation to indoor environment is reduced, and the good temperature environment can be preserved while ventilation is not influenced.
According to the change of environment, when winter, can make hot-blast entering indoor, in the time of being convenient for ventilate, still can do benefit to the maintenance of temperature in the passive building, prevent that cold wind from getting into, and influence the heat preservation performance of passive building, in summer, can make cold wind get into indoor, can realize the decline of temperature in the passive building, prevent hot-blast entering and make the temperature rise, can assist the regulatory function of temperature in the building, effectively improve the result of use of passive building, improve the comfort level of living.
