How about the sun room? Is it hot in summer?

The sun room is not hot in summer. In summer, the sun shines in the sun room and absorbs the sun. The air temperature in the sun room rises, forming a temperature difference air layer. The closer to the top surface, the higher the temperature. We opened a skylight at the top (/kloc-a skylight below the top surface of 0/5 square meters) to let hot air flow out to the top surface. While the low-temperature air at the bottom is replenished (stack effect), and the indoor air automatically and rapidly circulates to cool down.
