建筑师提供的文字说明。2016年2月，国家住房委员会Conavi（以西班牙语首字母缩写）更新了其提供联邦补贴的业务规则。新条例规定，使用传统材料和建设性系统，例如竹子、稻草、Bajairee、Palm、Carrizo和Wood，被认为是不稳定的，拒绝利用这些材料获得联邦资金给自建做法。

Text description provided by the architects. In February 2016 the National Housing Commission, CONAVI (for its acronym in Spanish), renewed its operating rules for providing federal subsidies. New regulations established that the use of traditional materials and constructive systems such as bamboo, straw, bajareque, palm, carrizo and wood, is considered precarious, denying access to federal funds to self-construction practices with these materials.

因此，与Tepetzintan社区通过五个技术培训和参与式设计讲习班联合开展的第一次住房活动被丢弃，以获得政府的支持，使居民难以自行建造住房。

Therefore, the first housing exercise, carried out jointly with the community of Tepetzintan through five workshops of technical training and participatory design, was discarded to receive government support, making it difficult for residents to self-construct it.

鉴于这种情况，我们与Tosepan Titataniske和Tosepan Ojatentekitinij土著合作社一道，决定进行第二次住房活动，以避免将当地竹类作为结构要素，以遵守CONAVI已经实施的条例。

Given this scenario, together with the Tosepan Titataniske and Tosepan Ojtatsentekitinij Indigenous Cooperatives, we decided to make a second housing exercise that avoid using local bamboo species as structural elements in order to comply with the regulations already imposed by CONAVI.

这第二次演习保留了模块化和预制建筑系统的基础上，由竹材制成的旧哈米。施工系统只使用三个单元(两个桁架和一个面板及其变体)；这些单元是在结构框架完成后预制和组装的，这大大减少了现场施工时间。此外，大约装配时间为一周，降低了低预算项目的劳动力成本。

This second exercise preserves the modular and prefabricated building system based on panels made with bamboo oldhamii. The construction system uses only three elements (two trusses and a panel with its variants); these elements are pre-fabricated and assembled once the structural frames have been finished, which significantly reduces site construction time. Also, the approximate assembly time is one week, reducing labor costs for a low budget project.

一旦安装，竹子板上涂有ixtle(用来制作咖啡袋的当地组织)和一层薄的灰浆。一旦基础结构已放置，梁和随后的生态板是固定的。最后一种产品是由食品级铝废料制成，具有热、声和抗菌性能。

Once installed, bamboo panels are coated with ixtle (local tissue used to make coffee sacks) and a thin layer of mortar. Once the base structure has been placed, the beams and subsequently the ecolam sheet are fixed. This last one is a product made from food-grade aluminum waste, which gives thermal, acoustic and antibacterial properties.

除了当地的材料，使村民能够提供实物和劳动力，以降低他们的住房成本，该项目具有最佳的环境性能。在水的情况下，雨水收集和湿地用于再利用灰色水和生物消化器进行污水处理。在气候方面，实施了基本的生物气候战略，以应对该地区的高温。

In addition to local materials, which allow the villagers to contribute in kind and labor to reduce the cost of their homes, the project has an optimum environmental performance. In the case of water, rainwater harvesting is used, as well as wetlands for reuse of gray water and biodigestor for sewage treatment. As for the climate, basic bioclimatic strategies were implemented to combat the region high temperatures.

在空间方面，这座房子符合纳瓦特人的习俗和传统，他们在主大厅里放置祭坛-这是房子的中心部分-并烘干咖啡和玉米作物。厨房具有透气性，能透出木柴的烟雾，传统格子的设计可以回收。

In terms of space, the house responds to the customs and traditions of Nahuatl people, who employ a main hall where they locate the altar - the central element of the house - and dry the coffee and corn crop. The kitchen has a permeable character to let out the smoke of the firewood and the design of traditional lattices is recovered.

第二次演习由全国住房委员会颁发，并在“第一次全国农村住房竞赛”中获得银牌，并获准接受联邦补贴。然而，我们将继续寻求第一次活动的可行性，因为我们坚信，我国的公共住房政策必须认可传统建筑材料和建筑结构体系，并促进土著人民的自治、本土建筑的价值和无形知识的保护。

The second exercise was awarded by CONAVI with a silver medal in the "First National Rural Housing Contest" and approved to receive federal subsidies. However, we will continue to seek the viability of the first exercise as we firmly believe that traditional building materials and vaconstructive systems must be endorsed by public housing policies in our country and promote the autonomy of indigenous peoples, the value of vernacular architecture and conservation of intangible knowledge.
