建筑节能与改善建筑功能是矛盾对立的两方面， 讲节能， 限制了通风， 产生了房间空气质量问题；而满足了房间空气质量的通风，会产生能量大的损失，经济负担太大，一般住户难以承担。也是国家政策所不允许。所以，处理好这一对矛盾是解决建筑节能的关键问题。中国四合院建筑是既解决建筑节能又改善功能的典型，作者将对此进行论证。对被动太阳房因能量有限是绝对不能通风的，也产生室内空气质量问题，这可采用在四合院建筑形成被动太阳房来解决房间空气质量的问题。还研究了大气长波辐射的利用、强化和减弱的措施。
Building energy efficiency and improving building function are two aspects of contradiction and contradiction. Energy saving is concerned, ventilation is restricted, room air quality problems are generated, and ventilation that satisfies the air quality of the room generates large energy losses, and the economic burden is too large. Hard to bear. It is also not allowed by national policies. Therefore, to deal with this contradiction is to solve the key issues of building energy conservation. China’s courtyard buildings are typical for both building energy conservation and improving functions. The author will demonstrate this. Passive solar houses cannot be ventilated due to limited energy, but also produce indoor air quality problems. This can be used to form a passive solar house in a courtyard house to solve the problem of room air quality. The measures for the use, enhancement, and attenuation of atmospheric long-wave radiation have also been studied.
