The effect of bio skin facades on daylight and thermal performance in eductional space

Abstract EN

Openings of external facades of the building is the element responsible for the perméabilité of natural lighting to the architectural space, as increased the percentage of openings for the external facade, greater the amount of daylight in the space, but it is accompanied by thermal gain inside the space.

Therefore, the research focused on designing a simulated dynamics skin facade for the of opening and closing the gaps of the cactus plant when exposed to the sun, but the simulation is done indirectly according to the organization 3.8, which is an organization responsible for simulating nature in various fields[1].

As the dynamics of movement in the cactus plant to reduce the transpiration process in the plant for the ability to adapt and survive, while the dynamics of opening and closing in the simulated interface of the plant to reduce the heat gain with the distribution of the amount of light required during the educational space (200-500 lux) according to the Egyptian code and ASHRAE -55 [2], for the student's ability to adapt with in the space and perform his mental tasks.

The skin facade was designing and the effect on the optical and thermal performance inside the space was measured using the Grasshopper-Rhino program, which is among the many available programs, but it allows the user to design a variable input model associated with it.

Measure both the thermal and optical performance of the space using Diva, Honeybee to compare the thermal and optical performance before and after using skin facade was Mimic of nature.

It was concluded that biomimetics contribute significantly to achieving thermal and visual comfort in educational spaces.
