Post-tsunami threat to coastal area has increased from time to time. With increase a  temperature of earth which securities will melt ice at the Pole. Improving surface of  water at sea. Various natural disaster in coastal area such as flood, abrasion and large waves that can damage the wealth of society. Not only that only become a threat but tsunami waves can destroy the mainland.

The area of Aceh is one the region never happen Tsunami. This Tsunami occurred on 26 December  2004 <a href="http://nationalgeographic.co.id/berita/2012/12/26-desember-2004-gempa-dan-tsunami-getarkan-aceh">[ source ]</a>. The disaster has eroded most of mainland coast. Impact of the tsunami is death, bodily injury victim, damage and damaged property. The land is located in coastal area that have a higher temperature heat from city center and regional higher. Climate can be classified as a tropical climate. To know  condition of  existing climate, then what architecture approach can solve problem?

## Approach Architecture bioclimatic
The approach that directs architect to consider relationship between form of architecture with its environment is Architecture bioclimatic. By knowing climate of a region, then this approach can save energy consumption of building. 

> To maintain ideal condition of building, for example temperature, moisture and lighting and air circulation.

Based on above quotation, that needs to be done is determination of  orientation building to create energy conservation. The order of building with openings facing north and south to reduce insulation hot. A good orientation is put smallest building facing east. Then outer walls open room. Transitional space injector and around side of the building as air space. This space as a mediator between inner and outer space of building. This function as a corridor outside may inhibit heat transfer.

## Bioclimatic approach to the region of coastal


> Bioclimatic architecture is an integrated concept in design of building where system structure space and  construction of building was able to guarantee a comfortable conditions for inhabitants.

The change of approach using principles of architecture bioclimatic. Focus on transitional space, wall of the determination orientation and landscape is very important.

The arrangement of building is not symmetry that happened arrest wind from  north and south sides because he dominant landscape  toward east and west. On the west side and east of main building was given terrace wide enough and air ventilation wood so that rays and heat sun is not directly affected by wall of room. There is also a roof space wide enough as transition of  sun.

To control air in building at tropical regions. outside walls must can be moved. This means that ventilating ducts must be moved. The aim is to satisfy, then about landscape, should be  Ground Floor of the building tropics open out. Landscape that is located in the middle and around a building large take effect against reduced hot temperature. Use of passive shading to inhibit sunlight but can also be used to natural lighting conditions in form skylight <a href="http://herusu71.blogspot.co.id/2015/10/perancangan-pasifpassive-design.html">[ source ]</a>. This is closely related with natural ventilation because of ground floor very important to note. Not only that but also plants and landscape can also be used to create an ecological and aesthetic aspect also oriented on building more cool and comfortable. Thus can unite organic element of plant with building. 

So that building can absorb O<sup>2</sup> and remove CO<sup>2</sup>  and cold has backfired on building <a href="https://hends86.wordpress.com/2011/07/01/karbon-dioksida-co2-efek-dan-penanganannya/">[ source ]</a>. In addition, also created the wall facing sun rays directly. Special to tropical regions are located on east and west.

## Conclusion
Bioclimatic approach produces design to respond development of land in tropics, especially at a higher temperature as the coastal areas. implementation principles of bioclimatic also is very appropriate even though the orientation dominant land facing to west and east.
