Research / Kinetic Facade System

Kinetic Facade System

This research explores the design and performance evaluation of a kinetic facade system aimed at improving environmental performance in office buildings. The research addresses the challenge of excessive solar gain and visual comfort in buildings with changing environmental conditions.

Research Overview

The primary objective is to develop a simulation-based, performance-oriented design workflow for kinetic facade systems, incorporating both digital modelling and physical prototyping. Key performance parameters include daylight availability and solar heat gain control, which are essential for reducing energy consumption and enhancing indoor comfort.

The study utilizes parametric modelling tools such as Rhino3D and Grasshopper, integrated with environmental simulation tools including Ladybug, Honeybee, Solar tools, and Energy Plus to evaluate design iterations. Optimization was performed using Galapagos, while physical prototyping and testing were conducted using microcontrollers (Raspberry Pi), actuators (stepper motor and linear actuator), and environmental sensors (LDRs) to validate the responsiveness.

Design Method

01 Literature Review
Study technologies, materials, tools, and case studies related to kinetic facade systems.
02 Simulation Setup
Define the baseline model, environmental inputs, facade parameters, and performance criteria for testing.
03 Design Development
Develop an optimised design through a simulation-based iterative process.
04 Fabrication and Installation
