Embodiment 1

[0036] Taking Beijing as an example, such as figure 1 As shown, the building includes a glass curtain wall 1 facing the sun, a plant wall 2 facing the shade, a prefabricated wall 3 facing east and west, and a solar photovoltaic panel 10 inclined to the south.

[0037] The walls on all four sides of the building form an angle of 90°±5° with the roof, and the angle between the roof and the ground plane is 17°. The calculation basis for this angle is to refer to the solar altitude angle a on the summer solstice in the area, which is the northern latitude of Beijing on the summer solstice. is 40°, the summer solstice sun directly shines on 23°26′N, then the summer solstice solar altitude angle a=90°-(northern latitude-summer solstice sun direct point)=90°-(40-23°26′)=73° 26′, the angle between the roof and the ground plane is b=90°-a=90°-73°26′=16°34′≈17°, because the angle between the roof and the north and south walls of the building is 90°, considering the Self-shading system,...

Embodiment 2

[0045] Take Yangzhou as an example

[0046] An energy-saving prototype house building based on the environment, its roof is perpendicular to the solar elevation angle at noon on the local summer solstice, and the included angle between the roof and the ground plane can also be 9°. The basis for calculating this angle is to refer to the solar altitude angle a on the summer solstice in this area, that is, the north latitude of Yangzhou on the summer solstice is 32°24′N, and the sun directly shines on 23°26′N on the summer solstice, then the solar altitude angle a=90°-(North latitude on the summer solstice degree-summer solstice sun direct point)=90°-(32°24'-23°26')=81°2', then the angle between the roof and the ground plane is b=90°-a=90°-81°2 ′=8°58′≈9°, because the angle between the roof and the north and south walls of the building is 90°, considering the building’s self-shading system, the inclination angle of the sun-facing facade should be consistent with the sun’s elevati...

Embodiment 3

[0048] In Beijing, for example

[0049] An environment-based energy-saving prototype house building, the angle between the roof and the ground plane is 42°, which is based on the calculation results of the monthly average total solar radiation of different inclination angles of the inclined surface, and the maximum total solar radiation of the year is obtained. The inclination angle corresponding to the amount of radiation, and considering the overall southward inclination of the building, in order to reduce the structural load, the minimum value is taken, and the overall southward inclination angle of the building is 90°-42°=48°, that is, the building faces the sun. The included angle with the horizontal plane is 48°, and the sun-facing and yin-facing facades are always kept parallel.

Abstract

The invention relates to an environment-based energy-saving prototype house building, which comprises a sun-exposed roof, a sun-exposed facade, a shade-exposed facade, an east facade, a west facade and a natural vent pipe. The environment-based energy-saving prototype house building is characterized in that the sun-exposed facade and the ground form a certain included angle; the range of the included angle takes values between a location solar elevation angle on summer solstice of a prototype house building and a location solar elevation angle on winter solstice of the prototype house building; the sun-exposed facade and the roof are kept at an angle of 90 degrees; and the sun-exposed facade and the shade-exposed facade are kept parallel. According to the environment-based energy-saving prototype house building, a photovoltaic panel can exert the maximum efficacy, the sun-exposed facade can realize the purpose of passive sunshading, the heated phenomenon of the indoor space in summer is reduced, the indoor temperature can be regulated by the northward plant wall design, industrialization is realized, a construction period is short, and the material loss during construction is low.

Description

technical field [0001] The invention relates to a building, in particular to an environment-based energy-saving prototype house building in which functional requirements are conventionally combined with natural renewable energy. Background technique [0002] Prototype, English is prototype, meaning sample, model. It refers to presenting the main functions of the system to users in a visual form in order to solicit user opinions and clarify user needs. A prototype is a system that can actually run, can be modified repeatedly, and is constantly improved. As the name suggests, the prototype house—in fact, it is the exploration of green and environmental protection in building products for many years, and the experimental construction is carried out in order to pass the practical test and continue to improve. [0003] The disadvantage of the current ordinary buildings is that the level of industrialization is low; natural renewable energy cannot be fully utilized comprehensive...
