First: build up the prototype.To define the boundary by three assistant walls.

Design cano-pis for each of the assist-ant walls.

Canopy design

The first design is too heavy. So I tried to design a lighter one.The truss used in the second design made the design even worse.Finally, to combine the structure with form could be a good a method.

The shadow test in the ecotect shows the canopy works.

Screen design

Combine Two Styles

Save those short ones

Start with one floor design

Depending on the Daily Radiation data I got from ecotect, define the radius of holes, hence to control the value of sunshine penetrating into room.

I defined a coefficient in the script to control the maximal and minimal value.

Obviousely, the cantilever is too long to be supported with a economical way.

The only way, for me, to fix this problem is to merge these three cantilever from east side.

To redefine the size of the holes on the east side.

The bi-layer screen was given up, due to it is too complex to be controlled. And it will be improved in the following design

Shadow pattern shows the single-layer screen works great, generally.

Inner view is not bad, espically the view from west side.

Sizes of the holes was defined exactly.

Section picture shows the screen works in the Dec 21th

But the screen has its own problem. Al-though the screen works very well, the scale of the whole screen is still too big. But just for the assignment which is to design a screen to respond to the sun, I think it works.

For the holiday house design, I did a weather research, I did comparison between CAPE SCHANCK and CAPE TRIBULATION in 5 parts1, Temperature (To get the R vaule) (main drives)2 , Solar exposure ( The area should be coverd) (main drives)3, Arid situation (If it is necessary to design a water saving device)4, Wind (Wind load for structure) (secondary drives)5, Humility (The façade material) (main drives)

The temperature in cape tribulation is a huge problem.For the cape schanck, which is in Mel, the temperature is not that high.

Global solar exposure is the total amount of solar energy falling on a horizontal surface. The daily global solar exposure is the total solar energy for a day. Typical values for daily global solar exposure range from 1 to 35 MJ/m2 (mega joules per square metre). The values are usu-ally highest in clear sun conditions during the summer and lowest during winter or very cloudy days. (To decide how much area should be covered)

For cape tribulation, the drainage is a huge problem.

Compared with cape tribulation, collecting rain water is very important in cape schanck,vvespecially in the dry season

The wind in Mel is not too strong The wind in cape tribulation is very strong, sometime.

To decide which façade material should be used.

In cape tribulation, timber is the best choice.In cape schanck, concrete, Alucobond, are all good choice.

Holiday House design

“ Gill “ design.The ventilation is a huge probelm. In the heavy wind day, I want the gills back to the wind direction.

In the weak wind day, I want these gills face to the direction of wind to reinforce the venterlation, hence to reduce the temperature inside.

Experiment shows that if the fin boards back to the wind direction, there still is some flour fly into the box, which means these is a possibility that even in the heavy wind day, the room could get good ventila-tion.

Naturally, when the gills face to the wind direc-tion, the venti-lation is rein-forced.

The basic shape test shows me, the sharper the shape is the better for the house to reduce the wind load.

In order to reduce the wind load, I designed the house in minimized length of the cross section. And optimize the house from the simplest shape, test it as well to get helpful data.

Depending on the experiment of gill-board, the gill-board will rotate relay-ing on a vertical axis.

Bend the side facing the main wind direction, and give the connection a shape angle, to reduce the wind load.

Give the roof a fold to prevent the roof from being absor-ded up

To cover the shade from the veranda, i have to entend the roof.

In order to cover the shade from veranda, I have to extend the roof too much, so, I have to bend the roof down, and finally bend it down totally.

The height of roof

The roof was designed to cover the shade from 8:00am to 5:00pm with the help of horizontial louvers.

It is easy to see the thickness changes from the section pattern.

This part shows the general design direction.

Depending on the data collected from ecotect, the functions were deploied into the design.

Depending on the topstrucutre, the rough struc-ture design was improved.

Process of Optimization

Ideal density for the roof
