巴勒斯坦的加沙地带有着丰富的历史,是世界上最古老的地区之一。历史长河中的文明浸润了它的建筑文化,留下了大量的历史遗存。虽然战争破坏了其中的一部分,但是并没有影响它的独特特征。加沙地带属于海洋性气候,紧邻的地中海为它带来了干燥温暖的夏季和略微凉爽的冬季,也影响了建筑的布局、空间、材料与使用。本研究通过实地测试与调查,走访加沙地带历史街区的住宅区,对传统的砂岩材料、泥土材料住宅开展调研,采访生活在那里的巴勒斯坦人,分发调查问卷,进行定量和定性的数据收集和分析。通过与现代的混凝土材料住宅进行对比,探讨传统住宅与现代住宅在热舒适方面的室内环境质量。研究表明,砂岩材料住宅的热舒适性更好,但是也有其不足,如占用更多的土地和建筑材料的匮乏等。基于调研与分析,本研究设计了一栋使用传统绿色设计策略但采用现代材料的热舒适良好的现代住宅建筑。这座建筑在夏季和冬季都不需要使用任何冷却或加热设备即可达成良好的室内热舒适环境;同时它被设计成一个大家庭的房子,以尊重加沙人的文化,让已婚的儿子和他们的父母住在同一栋楼的另一个楼层。研究还使用ECOTECT模拟软件对该建筑进行了性能模拟,与同一地点的普通现代混凝土住宅进行了比较。本研究对设计住宅和对比住宅的PMV和PPD进行了比较,发现设计住宅在四个测量时间除了早上庭院区域的值(晚上、早上、中午和下午)均为中性,明显优于对比住宅。我们的研究结果表明,带有庭院和保温材料的设计建筑在夏季比普通的混凝土住宅温度更低,而且它的热舒适性比同类房屋更好;另一方面,因为它不使用任何电气冷却和加热设备,所以它在经济上也更好。

As acknowledged that the exploration is the first step before reaching the discovery of profitable economic raw materials. However, it is also representing a high risk financially because it is possible that the areas discovered is not economically worthwhile, at that time the stakeholder will confront difficult return their exploration expenses. Therefore, the exploration process executed in multiple stages before increasing expenses for the detection. The business of mineral exploration, one of high cost investment especially if it was in rugged mountain areas, which is difficult to reach and has a very high cost of access, consequentially increased the exploration costs. The reasons for doing this research in rough mountainous area using geospatial technology, can be justified to be valuable, time-saving and cost-reducing. Therefore, we can see that one of the solid factors that helped the study is using of GIS technology in the rough terrain area, which strongly and effectively contributes to the display of spatial information and linking the study, and analysis of the information collected by using GIS programs. Subsequently, its benefits minimizing exploration costs, and selecting targets with confidence and effective field work. Most of the data related to the operations of mineral exploration have a spatial nature. So, GIS has the capability for storage, updating, revising, displaying, retrieving, processing, manipulating and integrating of different geo-spatial data. By ending of this study, we will be able to save time and money and increase profitability and efficacy.
