The Brief The objective of this brief is to use BIM for design and better decision making. The client has asked to re-design the facade of AMDC building to propose a human centred design and innovative skin, responsive to environmental conditions.

The design of facade should also represent the identity of school of design At swinburne University of Technology.

Approach on design should be made understanding and analysing environmental factors. Once analysed, one should identify the parameters that are most important to consider in design. Itterations in form and operations shoud be generated based on choosen parameters.

AMDC FEATURES Swinbunre AMDC is located on Swinbirnes Hawthorn campus and faces Burwood road.

The current design of the facade features fins like horizontal shading on north and south faces and a giant shell like form on east and west faces with openings.

The building also have a heritage facade on south face on levels 1&2 facing burwood road that needs to be sustained. The enterace is also through this facade.

There is another enterance through the west of the building.

Level three is one of the highly engaged areas hosting events lectures and place for students to study.

Level 4 & 5 are teaching spaces including classrooms. Level 6 has computer labs and spaces for PHD candidates. There are some hot desks on the floor too. Level 6 has an opening like a balcony.

Level 7,8,9 and 10 are all faculty offices and have a research hub too.

MIND MAPPING A DWG file was extracted from the Revit and imported to Rhino to perform analysis. Context geometry was generated in rhino to obtain accuracy.

Being an occupant of the building, the most important factor that seemed to be improved was the energy capture and loss. During peak summer the building creates very warm interior environment and in winter the glazing cannot stop the cool weather to change the interior environment.

From the experience, the group decided to emphasis on heat gain and loose by analysing solar radiations while still considering other relating parameters.

The process began by generating Solar paths for summer and winter. From the result, a decision to prioritize the northern facade with east and west were undertaken. While south could be an asthetic opportunity.

The lower winter sun position and higher top summer position can be utilized by a responsive kinetic pannel facade. The facade being responsive would relate to Swinburne’s idea of innovation.

Analysis AMDC EXISTING Once decided upon choosing solar movement as a parameter, Ladybug - an environmental analysis plug-in in Rhino 6 was used to generate Sunlight hours and Solar Radiation for Summer and Winter.

The Summer period ranged from 1st December to February 28th. The Winter Period ranged from 1st June to 31st August.

From the analysis we observed the relation between the amount of sunlight received and the radiation. During winter, there is high Sunlight hours and radiation on north. There is heat gain during this however the heat is lost due to unedequete stopage. The north facade in summer on the other hand gets medium sunlight hours and medium to low radiation.

Sunlight Hours W

Concluding the analysis, the orientation of the building is perfect to optimize the passive solar energy. The approach should be to panelize the North, East and west with some responsive facade while keeping the south facade static/interactive. The facade should allow Winter sun and shade Summer.

Concept Refinement ThIs design was choosen during Mid-Project Critic.

The design consists of of static panels of angled extruded square. The extended face of the module is also scaled.

North

The Angle of extrusion and the scale of the face varies upot the location of the panel on building and the amount of sunlight and radiation it produces.

The Panels on north Facade have extrusion angled downwards and scaled more. The east and west facade have smaller scaled faces and longer extrusions.

The Panel were generated upon the the angle at which the summer and winter sunlight comes in contact. Overhead / top position of the summer sun is shaded by longer extrusion. The winter sun on another hand can be utilized by scaling up the face of the module while still having an extrusion to shade summer sun.

Presentation Feedback Feedback From Crit The critic suggested the next step of the design process involved considering the size of panels and cost. Further consideration of panels should be made to reduce manufacture risks and complications.

Making the design less complicated and modular was a suggestion by making the form simple. The Rectangular grid system wad also questioned.

What to consider The Design should be less comlicated. Should consider another system with repetetive module that are asthetically pleasing. Occupants should have control over some. The functions and the programs should be considered too in relation with the design of the panels. The features of a responsive kinetic facade should still be a part of the design.

Revised Design DESIGN The design was inspired by the form of a flower and a system of a Japanese fan. The module changes the size from central. This module was created so that it can be manually controlled.

OPENED PANELS

Winter System During the winter season, the module would be opened to allow sunlight enter and heat up the floors. During night, the module closes up capturing the heat inside avoiding heat loss.

MANUALLY CONTROLED PANELS

Summer During summer, the module closes up and avoids the radiating sunlight to overheat the rooms. The modules also opens up controlled allowing the air to cool the rooms and provide natural ventilation.

The material is a semi-transparent material only casting filtered light. This causes less radiation.

CLOSED PANELS

WINTER SYSTEM OPENING

THE HEAT GAINED DURING WINTER DAY CAN BE FENCED AND AVOID LOSS BY CLOSING THE PANELS AT NIGHT.

SUMMER OVER-HEATING CAN BE AVOIDED

BIM Work-Flow

A DWG FILE WAS EXTRATED TO IMPORT IN RHINO.

THE CONCEPT WERE ANALYSED USING LADYBUG AND COMPARED.

THE MOST FEASABLE DESIGN WAS REFINED AND DETAILED TO EXPORT TO REVIT

THE GEOMETRY WAS EXPANDED TO REFFERENCE IN GRASSHOPPER.

THE REFFERENCE GEOMETRY WAS PLUGED INTO THE ANALYSIS AND GENERATED SOLAR PATHS

AFTER ANALYSING THE CURRENT AMDC BUILDING FACADE SKETCHES WERE CREATED FOR CONCEPTS.

THE CONCEPTS WERE DEVELOPED IN RHINO AND REFFERENCED.

REVIT WAS USED TO DOCUMENT THE MASS FILE AND APPLY ON THE FACADE. DOCUMENTS WERE ALSO CREATED

ENSCAPE WAS USED TO GENERATE RENDERS AND VISUALIZATIONS.

ADOBE PACKAGE WAS USED TO CREATE THE PRESENTATION AND GRAPHICS

Reflection The process was very engaging, uncomfortable and frustrating but intresting. The process began with extracting a rhino compatible model from Revit and unblocking the block instances and analysing the model. In grasshopper, while running ladybug, we realized that the plugin requires very high quality tech to perform analysis on the accurate state of the model. From this experience a polysurface low weighing model was generated to avoid the program crashing.

From the analysis results we decided to have concepts based on responsive, kinetic facades. The ideas were based upon this theme. Swinburne highly emphasis on technology and so we decided to design an engaging kinetic facade.

From the mid-project break, the critic were happy with our approach and liked the design. However questions were rised upon choosing the design in comfort level and unconsidered fact of con efficiency. The design for Part b was then designed according to the critics suggestions.

The process was very professional. Different members had different roles during the process. While one would analysis, the other would develop a model in rhino and another documenting it in revit. The during the process, we constantly went back and forward between Rhino, Grasshopper and Revit. The design was constantly informed by the analysis and programs. The unit demonstrated what a working in BIM environment looks like.
