Introduction

The Blue Planet made by 3XN won the competition for the new Denmark Aquarium. This is inspired by the whirliing streams of the sea. From the round center hall of the building, the different parts are "whirled" in the slightly curved sequence of rooms. (3XN, 2011)

Floor Area : 9,000 m² Use : Recreation, Aquarium Expected Completion : 2013

Mass Process

1.1. Found proper parametric equations

Ø Used the parametric equations for the spiral, which are shown below.

1.2. Made the parametric line by using parametric equations

Ø Used ‘x=t sin t and y=t sin t’ instead of ‘x=t cos t and y=t sin t’, because the direction of the spiral that I want is inverse.

Ø Each parametric line for each mass was used

(z_scale=height, r_scale=length, a_scale= angle)

Wing #1 (r_scale=2.5, a_scale=6.0)

Wing #2 (r_scale=2.0, a_scale=6.0)

Wing #3 (r_scale=5.0, a_scale=2.0)

Wing #4 (r_scale=4.0, a_scale=2.0)

Wing #5 (r_scale=4.5, a_scale=2)

1.3. Made vertical planes by considering the actual building shape and applied parameters to change widths and heights of the mass keeping same shapes

Ex) wing #1 (e.g. mass #1)

1.4. The height, the width and the angle are changed by the parameters

Ø Below is changing by the height.

Ø Below is changing by the width.

Ø Below is changing by the angle.

1.5. Limitations

ØBasically, I planned the mass can be transformed by the spiral parametric line, but the mass was not changed by the spiral parametric line. The mass was moved by one of the parametric points of the parametric line, not changed by the parametric line.

Ø I tried to make the height and the width of the mass longer or shorter in one direction, but the height and the width were changed bi-directionally.

Skin Process

2.1. Made an applied rhomboid surface for the spiral mass

Ø I needed a rhomboid surface without a gap from the spiral, so I referenced the ‘octagon curtain panels’ tutorial. ( http://blog.cadway.com.au/2009/05/conceptual-mass-2010-octagon-panels.html )

2.2. Made a Building Integrated Photovoltaic (BIPV) feature to the roof and the wall

Ø I wanted to add a Building Integrated Photovoltaic (BIPV) feature to the roof and the wall, so I determined a proper shape of the photovoltaic (PV) panel for the design of the actual building.

Ø I applied the photovoltaic panels to each wing of my building model.

Ex) The fifth wing

2.3. Angles of the photovoltaic panels are driven by the sun path

Ø I made a curtain panel by pattern family which is driven by an angle parameter.

Ex) The second wing

Angle=45⁰ Angle=90⁰

Ø For best performance, PV systems aim to maximize the time they face the sun. Solar trackers aim to achieve this by moving PV panels to follow the sun. The increase can be by as much as 20% in winter and by as much as 50% in summer.
