Eco Factor: In Hedgehog, the rainwater + gray water = service water supply
Designed by Cheungvogl architects, the Hedgehog concept of building is wrapped with the a skin that has been made of high gloss finished PVC sticks. These sticks, owing to their virtue of diffusing light, are called “Light Diffusers.” The skin of high gloss PVC sticks appear like golden-silvery shimmering rain. But, when seen from a close distance these PVC sticks become almost invisible. The direct sunlight is reflected due to the presence of light diffusers and reaches the interiors as diffuse or as we can say soft welcome light. The idea of openness manifests itself in larger intensity on the inside, which I think can be credited to the lighting provided with the help of light diffusers. In addition to using PVC as one of the main ingredients, what really gets this design rolling is that on the ground rain water is collected to feed together with recycled gray water into service water supply.
