| description | Some critical directions of building facade are highly exposed to the sun and it
requires a smarter shading device than conventional shading devices that fail to
adapt with nature of sun motion may occur during day, month and seasons.
In this study, parametric scripts were written to propose six Kinetic facades
design to enhance daylight performance followed by theoretical comparison. The
case study was selected to be on Stare Central office building in Cyberjaya,
Malaysia to be as virtual model which was built in Rhino for the daylight
simulation and to conduct physical daylight measurement by Lux meter device
to validate the simulation through a comparison between the physical daylighting
measurement with the virtual simulation.
Parametric Daylight simulation was performed on Rotating Facade design
through Rhino software using plugins Grasshopper and Diva with a Radiance
interface based on LEED V4.1 criteria. The daylight simulation was divided into
four phases, starting with annual simulation for benchmark (the actual existing
facade) and different glaze materials followed by simulations for facade
parameters (size & rotation angle) ending with the hourly daylight simulation.
The annual simulation was conducted using Daylight Dynamic Performance
Metrics specifically; Spatial-Daylight-Autonomy (sDA300/50%) and Annual-
Sunlight-Exposure (ASE1000/250hr). While the Hourly simulation depend on
modified metric which is Hourly Spatial daylight Autonomy HsDA and Hourly sun
exposure HSE from 8AM to 6PM in four days that represent the equinox and
solstice days.
From the results obtained, benchmark cases illustrate the need of highperformance
facade to decrease the recorded dangerous values caused by
direct sun radiation. none of the glaze materials achieved credit of LEED
standards except Generic Translucent panel 20% with 1 credit. The rotation
angle 20˚ and 30˚ of rotating façade have achieved three credits of LEED in east
and west respectively as a static system. Finally, the study proposed two
optimized dynamic systems able to adapt hourly according to the sun position
and achieve higher performance than optimum static configure based on
comparison. |
