第三节被动式太阳房的建造被动式太阳房的性能优劣不仅要有优秀的设计方案,还应该结构简单易于建造,同时应该考虑到在长期使用中的方便。被动式太阳房能否推广普及并得到预期效果,很大程度上取决于经济投资。因此,在结构设计中单纯追求太阳房的高效率是非常片面的,应该把节约投资作为很重要的内容加以考虑,从设计方案、采暖形式、材料选择到施工方法及长期维护费用都应尽量贯彻因地制宜、就地取材、节约开支的原则。我国各地都有一些适合太阳房应用的建筑材料,如北方广大地区的群众有用土坯建房的习惯,实际上土坯是一种蓄热性能较好,又有一定隔热能力、经济方便的材料,在建普通单层太阳房时是完全可以用的材料。西北干旱地区可将麦衣、棉秆、羊粪球等加工处理后变成保温材料,填充在夹层中起隔热保温作用。山区可利用石头做成很好的蓄热墙体。有些地方 Section 3 Construction of passive solar houses The performance of passive solar houses must not only have excellent design solutions, but also be simple and easy to construct. At the same time, the convenience of long-term use should be taken into consideration. Whether passive solar houses can be popularized and expected effects are largely dependent on economic investment. Therefore, simply pursuing the high efficiency of the solar house in the structural design is very one-sided. Saving investment should be considered as a very important content. The design plan, heating form, material selection, construction method and long-term maintenance cost should be implemented as far as possible. The principle of adjusting measures to local conditions, drawing materials locally, and saving expenses. There are some building materials suitable for solar houses in various parts of the country. For example, people in the vast northern regions have a habit of building houses using adobe. Actually, adobe is a material with good thermal storage properties, certain insulation capacity, and economic convenience. When building a common single-storey solar house, it is a completely usable material. In the arid regions of northwestern China, Maiyi, cotton stalks, sheep dung balls, etc. can be processed into heat-insulating materials and filled in the interlayer to provide heat insulation. Mountainous areas can be made of stone to make a good heat storage wall. some places
