General code for civil building
1 General provisions
1.0.1 This Code is formulated to standardize the basic dimensions, technical requirements and general technical measures for spaces and parts of civil buildings.
1.0.2 This Code must be implemented for civil buildings.
1.0.3 The construction, use and maintenance of civil buildings shall follow the basic principles below:
1 In accordance with the principle of sustainable development, properly handle the interrelationship among human beings, buildings and the environment, and create rational spaces matching the usage functions;
2 Implement the policy requirements of energy conservation, land conservation, water conservation, material conservation and environmental protection;
3 Coordinate with the surrounding environment, and embody the characteristics of the times and regional culture.
1.0.4 It is up to the relevant responsibility subjects to determine whether the technical methods and measures taken in the engineering construction meet the requirements of this Code. Innovative technical methods and measures shall be demonstrated and meet the performance requirements in this Code.
2 Basic requirements
2.1 Functional requirements
2.1.1 The construction of civil buildings shall follow the principles of safety, sanitation, health and comfort, provide rational usage spaces for people's social activities such as living, working and communication, and the usage spaces shall meet the basic ergonomic dimension requirements.
2.1.2 The site selection of civil buildings shall meet safety requirements.
2.1.3 Residential buildings shall guarantee the living safety and privacy of residents, and meet the requirements of daylighting, ventilation and sound insulation.
2.1.4 Public buildings including educational, office and scientific research, commercial service, public activity, transportation, medical and people's livelihood service buildings shall not only meet the space and usage demands for various activities, but also satisfy the requirements of traffic and personnel evacuation.
2.1.5 When civil buildings combine different functional places, in addition to meeting the requirements of the above clauses, the following requirements shall also be met:
1 No functional place shall reduce the basic safety and sanitation standards of other functional places;
2 When functional places generating pollution or radiation are combined with other functional places, necessary safety protection measures shall be taken;
3 When functional places of different safety levels are combined, corresponding measures shall be taken to ensure the usage safety of each functional place.
2.1.6 Civil buildings shall be equipped with facilities and equipment that meet the basic usage function requirements.
2.1.7 Civil buildings shall be provided with corresponding safety and guidance sign systems.
2.2 Performance and measures
2.2.1 Civil buildings shall comprehensively adopt disaster prevention and safety measures for fire protection, seismic resistance, flood control, air defense, snow and wind resistance, lightning protection and other disaster risks.
2.2.2 The structure of civil buildings shall meet the requirements of the corresponding design working life.
2.2.3 Civil buildings shall meet accessibility requirements, and the facilities with accessibility performance shall be arranged in a systematic and continuous manner.
2.2.4 Indoor and outdoor decoration shall not affect the structural safety of buildings, and safe and environment-friendly decoration materials shall be selected. The connections between decoration materials, decorative surfaces or members/fittings and the main structure shall be safe and firm. Materials and structures of exterior wall decorative surfaces, components, doors and windows of buildings shall be safe and reliable, meet the functional and performance requirements within the design working life, and be maintained regularly during service to prevent falling accidents.
2.2.5 Prefabricated buildings shall adopt integrated, modular, standardized and universal prefabricated components and parts.
2.2.6 Outdoor public sites, building spaces, building components and public facilities and equipment of civil buildings shall be subject to regular daily maintenance, repair and supervision.
3 Building area and height
3.1 Building area
3.1.1 The building area shall be calculated as the horizontal projected area of the space enclosed by the outer surface of the external envelope structure at each natural floor (ground) of the building.
3.1.2 The total building area shall be the sum of the above-ground and underground building areas, which shall be calculated separately.
