5.2.3 The wind load for Dezhou shall be taken as 0.45kN/m2.
At 10m above the ground, 10-minute average annual maximum wind speed is about 26.86m/s.
When it is predicted that the wind velocity may exceed 26.86m/s, a notice for forcible withdrawal (evacuation order) will be issued.
5.2.4 In Dezhou, the earthquake-resistant fortification intensity is 7, and the design basic acceleration is 0.10g.
5.2.5 In Dezhou, the snow load shall be 0.35kN/m2, and the coefficient division of quasi-permanent value for snow load shall be II.
5.2.6 The horizontal load on the railing tops of stairs, stands, balconies, accessible roofs, etc. shall be set as 1.0kN/m2. The vertical load shall be set as 1.2kN/m2.
6.1.3 Fire suppression sprinkler systems are not required. The municipal water distribution system does not provide fire demand on site. Otherwise, the participating buildings have to define their own fire water tanks.
6.2.8 Water closets shall be fully functional, and shall be connected to the water supply and the sewage disposal systems.
6.3.2 The hydrostatic pressure of water supply beforeafter the threshold water meter in the building shall be no less than 0.050.1MPa, and the water supply pressure of the service pipe shall be no more than 0.35MPa.
6.7.1 Domestic water not in contact with the human body, such as water for landscapes, greening, vehicle washing, road watering, toilet flushing, etc. shallis recommended to make use of the non-traditional water sources such as urban recycled water, rainwater, building reclaimed water, etc.
7.3.1 The outdoor fresh air inlet and the air outlet shall be arranged to face different directions.
7.3.2 Measures for preventing the entry of sundries and rainwater shall be taken for the air inlet and the air outlet via screening or other approved methods.
7.5.2 The internal walkway longer than 20m shall be provided with an operable external window. The area of the external window shall be no less than 2% of the floor area of the internal walkway.
8.3.5 All power receptacles shall be safety receptacles.
8.4.2 The efficiency of interior lighting shall not be less than 70%. For shaded interior lighting, the efficiency shall not be less than 60%. The average luminous efficiency of light sources shall not be less than 60lm/W.
8.5.3 Metallic conduits and plasticPVC conduits may be used for distribution circuit wiring in houses. The tube wall thickness of concealed metallic conduits shall be no less than 1.5mm, and the tube wall thickness of concealed plasticPVC conduits shall be no less than 2.0mm.
8.6.2 The distance between high-voltage and low-voltage power receptacles shall not be less than 20cm.
9.1.4 Both the isolating switch and the circuit breaker between the PV system and the public grid shall have the function of breakage of zero line, and the phase line and the zeroneutral line shall be capable of being disengaged and engaged simultaneously.
9.1.6 The participating teams are allowed to consider storing the power energy up to 10kWh. Commercially available direct-current devices are permitted to be connected to the power storage system.
