三、发展太阳房的可行性和对策被动式太阳能建筑在我国从无到有,从点到面,总趋势是好的。我国不仅有优越的自然条件,而且在技术、经济上也具备发展太阳房的可行条件。我国太阳能资源十分丰富,全国太阳能资源丰富带(Ⅰ区,年辐射量大于628KJ/cm~2、年)和较丰富带(Ⅱ区,年辐射量为502—628KJ/cm~2、年)大都在北纬35°以北地区,其日照时数≥6小时的年总天数均大于250天。其中又以西藏、青海、甘肃西部、新疆南部的资源条件最好。处于北方采暖边缘地带的山东、
Third, the feasibility of developing solar houses and countermeasures Passive solar energy construction in our country from scratch, from point to surface, the overall trend is good. China not only has superior natural conditions, but also has the technical and economical conditions for the development of solar houses. China’s solar energy resources are very rich. The country’s solar energy resources are rich (I district, annual radiation is greater than 628KJ/cm~2, year) and richer district (II district, annual radiation is 502-628KJ/cm~2, year). In the area north of 35 degrees north latitude, the total days of sunshine hours ≥ 6 hours are greater than 250 days. Among them, Tibet, Qinghai, western Gansu and southern Xinjiang have the best resource conditions. Shandong, which is in the northern edge of heating,
