Implementation suggestions and practical application cases
In actual construction, the design and construction of rural houses should strictly follow the following principles:
- Reasonableness of site selection: Ensure that the building land meets the requirements of GB18055 and avoid low-lying and humid areas.
- Orientation optimization:Choose the best residential orientation according to local climate conditions. The angle between the dominant wind direction and the long axis of the building in summer should not be less than 30 degrees.
- Sanitary facilities configuration:Kitchens and bathrooms should have independent exhaust and drainage systems, and household toilets must comply with GB19379 standards.
- Material selection:Use environmentally friendly building materials to ensure that indoor air quality meets standards.
Actual application case: A temperate rural residence
In a temperate region, a two-story rural residence is designed according to GB9981-2012 standard:
- Sunshine hours in the main room ≥ 2.0 hours (winter solstice)
- Window-to-floor area ratio is controlled at 1/7~1/6
- Per capita living area ≥ 8 square meters, per capita volume ≥ 20 cubic meters
