Resense
Wind-Break-Ing
Due to the extreme climate change, we are forced to rethink a better coexistence with the nature. On the other side, our sensory for interacting with the nature is gradually weaken because of the global urbanization, which separates us from a natural environment. “Resense” tried to respond to these two problems with an architectural design.
With series of kinetic facilities driven by wind force, ”wind-break-ing” system is designed to reduce the wind-blown-sand disaster in the east of Taiwan and, furthermore, to train our body to resense the variations of the environment. This special system not only creates a conversation between the habitants and the surroundings but also achieves a new symbiotic balance in the nature and our daily lives.

Why we need to resense?
Dating back our past relationship with the nature, we relied on them for food. We were more aware of them because we knew that we were weaker. As
our technics improving, we started to believe that we can control them. The capitalism and the following urbanization enlarged the distance in fabricationand consumption. We have started to unlimitedly consume products withoutseeing the dying source. Having less limit in time and space, our sensation is steadily blunt.
Wind-blown-sand is interlaced by the seasonalinteraction in water, sand, and wind. It regularly happens in the drought season (Sep to Feb), referring to the northeast monsoon. In the past, Taitung county government has invested a lot to deal with this problem but those methods were all too palliative.
The most efficient one is the artificial wind-breaks, named Taitung Forest Park. The amount of fallout caught by the windbreaks is 5.86times more than in downtown. However, it is still improvable. The reason is that the planningof windbreaks mainly focus on preventing windinstead of dealing with the sand. As a result,“wind-break-ing” system is designed to improvethe ability for filtering the air.
As the first defence, the south bank is the most efficient place to block the sand and to lead the airflow into the windbreaks behind. There are two ways to subside the sand.
-
The wind-deflecting type leads down the airflow tothe dense windbreaks right behind.
-
The airflow passes through the wind tunnels, which causes fast wind speed then draw in more airflow, so the sand can be blocked by the sand- accumulating types as well as the windbreaks in the following open area.
Unlike the water, which is mainly influenced by the gravity, the wind is a complicated fluid type with three dimen-sional movements. In order to control the airflow, it does not work by partially blocking the airflow, because theeffect is far less than the main pressure-gradient force. Instead, it is important to create the difference in velocity/ pressure which guides the airflow to the direction with faster speed/less pressure.
To understand the principles of the wind movement, I used the CFD (Computational fluid dynamics) software to simulate the wind field and to find out proper forms for my design. At the end, I designed three prototypes fordeflecting the wind, blocking the sand, and accumulating the sand.
In order to transform the windbreaks into a better ecosystem, wind-break-ing system includes two other branched systems which are about the wood and the earth. Because this windbreaks is a pure forest, Iplanned to execute continuous cover forestry (CCF) to individually log and plant different species for creat- ing various forest condition. As a result, the logged trees can be provided to renew the structure of facilities thus become part of the system cycle.
On the other hand, because of having too much sand in the earth, the asparagus agriculture system in the sand-accumulating type is designed to enrich the soil condition. Due to the autointoxication during the growth of asparagus, the soil need to be fertilized or changed periodically. The changed soil which has more decomposers will be spread and improve the barren earth thus provide a better ecosystem to other species.
Once a better interface
with the nature is built, I believe that the interactivity between the nature and the human will evolve into next step. Instead of choosing between destroying or protecting, which is a binary opposition, a new symbiotic balance will finally occur when we start to resense indeed.
