Participation reward: 2 Wealth. Reward for correct answer: 9 wealth. Which of the following statements regarding the limit values for the heat transfer coefficient of the enclosure structures in public buildings is incorrect? ( ) (A) The heat transfer coefficient of the exterior walls is based on the average heat transfer coefficient. (B) The limits on the heat transfer coefficient of the building envelope are related to the shape factor of the building. (C) The limits on the heat transfer coefficient of the building envelope are related to the window-to-wall area ratio of the building. (D) In mild climates, it may not be necessary to consider the limits on the heat transfer coefficient of the building envelope.

Which of the following statements regarding the limit values for the heat transfer coefficient of the enclosure structures in public buildings is incorrect? (D) (A) The heat transfer coefficient of the exterior walls should use the average heat transfer coefficient. (B) The limit values for the heat transfer coefficient of the building envelope are related to the shape factor of the building. (C) The limit values for the heat transfer coefficient of the building envelope are related to the window-to-wall area ratio of the building. (D) In mild climate regions, it may not be necessary to take into account the limit values for the heat transfer coefficient of the building envelope. Answer: D. Refer to Article 4.2.2 of the “Energy Efficiency Standards for Public Buildings”. When the city where the building is located is in a mild climate zone, it is necessary to determine which city in Table 4.2.1 has the most similar meteorological conditions; the thermal performance of the building’s envelope should then comply with the requirements specified for the climate zone to which that city belongs. When the provisions of this clause cannot be met, a judgment based on trade-offs must be made in accordance with the requirements of Section 4.3 of this standard.
(D) In mild regions, the limit on the heat transfer coefficient of the enclosure structure can be disregarded
