(1) house type a; (3 points) Reason: Both bedrooms in Apartment A face south and face the sun, while only one bedroom in Apartment B faces the sun (4 points).
(2) No (3 points) Reason: From winter to the sun, the noon sun height angle in Hefei is the smallest. /kloc-if you can get sunshine on the first floor of building 0/4 at noon that day, you can get sunshine all year round. According to the calculation, the first floor of 14 building can only get sunshine at noon when the distance between buildings is at least 25 meters on the winter solstice (6 minutes).
(3) The winter solstice is the smallest day of the year. If the sunshine of the house on that day is not less than 1 hour, it means that the sunshine condition of the building is good. (5 points)
Test analysis:
(1) Investigate students' application of knowledge. Hefei is located in the temperate zone of the northern hemisphere, and the sun shines from the south all the year round. Considering the sunshine conditions, the windows of bedroom A in the picture all face south, while bedroom B faces north. Therefore, apartment A is more suitable.
(2) Examine the calculation of the sun angle. Building Hefei 14 can be illuminated by the sun at noon all year round, so it must be considered from winter to sun (because the solar altitude angle in the northern hemisphere is the smallest from winter to sun). Calculation: Then the minimum building spacing between the front and rear buildings, the distance between the front and rear buildings in the picture is 20 meters, so it can't be illuminated all year round.
(3) The Code for Planning and Design of Urban Residential Areas (GB50 180) takes into account the changing law of solar altitude angle, and the solar altitude angle is the smallest in winter solstice in China. In order to make the sunshine conditions in urban residential areas good, the windows should face south, so that the sunshine time is long and the living environment is good, especially the sunshine conditions.
