Look at the house, good or bad depends on the winter solstice, summer solstice, two days of lighting, there is no understanding, explained
It's not so troublesome. The lighting is really good. Just take a look at it, and the light will only take a few days to see
Look at the balcony of the house, facing the south of the lighting well.
Because the summer solstice is the longest day of the year, and the winter solstice is the shortest day of the year, so look at the two days of sunshine time, you can know the lighting of the house is good.In fact, you don't have to stay in your room all day, but you can record the morning and evening sun hours in your room during the two days. Summer solstice sunshine time is less than 6 hours, the winter solstice sunshine time is less than 4 hours, the room lighting is insufficient.
