e-mail from/to Auke

... copy of response to your e-mail:

Hi Auke
What I had in mind in the first place when suggesting GC was being able to model how the mechanisms you're proposing alter their shape, separately from consideration of actual loads and material properties
After that, as a second step, you could either export the geometry from your first (GC) models to a structural analysis program (maybe Diana, since that's what seems to be preferred by Andrew and Eliza) or perhaps some structural analysis could be programmed into the GC model, as for example your classmate Arjan is doing ... though I think that option may be too ambitious for the time available in this course.
In any event, yes, I think GC would be good at this stage for studying movement, since such a model would allow you to drive the deformation of the structure both by displacing nodes (which is essentially what happens when the structure reacts to external loads, passively) or by changing the lengths of elements (as in an active structure.)

ps I'll post this comment also to your blog, so that you have it all in one place.
pps Axel, let us know if you have any comments on this, please.

Hello Andre,
Thanks for your comment. It was my aim to indeed at least model one variant for Monday. Is GC the most suitable program to model the different variants? Is it easy to exchange a GC model to a program to test the performance, or is it possible to test the performance in GC itself?

Your diagrams give a nice analysis of system types whose performance you could explore.

It would be great if you could model at least one of them in time for the midterm presentation, with the aim of modeling all four (or more if other ideas come to you in the meantime) by the end of the course, allowing a direct comparison of their performances under identical load conditions.

Are you able to start modeling, for example in GC?

Congratulations on this step! It looks like you've developed a good way to generate the city 'grid' - which is similar in this example to recent work from Hadid's office, for instance as shown by Patrick Schumacher at last February's SmartGeometry event.

Of course, this way you don't really obtain the contrast between your building and the rest, which you've said you're aiming for, but you can always set the generating 'street' forms to rectilinear for that. In this case you can perhaps 'flatten' your building site by building a new volume whose footprint shape is the same as the site's (but perhaps offset outward if the surrounding street walls are not vertical), giving it sufficient height (or depth, in the downward sense) and doing a further boolean subtraction with it.

On the other hand, if your intent is to keep the surroundings rectilinear anyway, then perhaps it's best to model that by starting from a grid of points - irregularly spaced, if you prefer - and putting a 2-D array of planes and vertical vectors on that set of points, so you can build simple boxes with independent heights right from the beginning.

Anyway, looking forward to seeing the midterm presentation, AC

Following up on Axel's comment about bringing the technical analysis results back into the design of the form, two of the (many) approaches you could take are:
1)inverting the deflected shapes so as to arrive at more compression-controlled structural elements;
and/or
2)using the undeflected and deflected shapes to define trusses rather than beams (which have the potential to form a space, not just support the loads/program.)

As I discussed with Axel on Friday, it might be helpful for you to approach your study of Decon by means of comparisons. That is, if you're searching for parametric/associative or other generative rules for defining Deconstructivist forms, you can also look at rules for Constructivist, or Modernist, or other formal languages, and explore how changing those rules might give you the rules you want.

Of course, it's important for the purpose of this course (since the time is so short) that you work with a fairly simple design, just complex enough to be recognizably belonging to the language you're working in, but not requiring too many rules, so that you can easily test variations (both within the rules, and variations of the rules) and reach some conclusions about the question you're researching.

The rules can be expressed both in words and diagrams, to aid you in modeling and/or scripting them.

... also, the survey can help you get more information about the color effects/interpretations you're reading in the literature - for example, whether a significant number of people agree with those, and how those who may disagree react (or at least describe their reactions.)
This type of feedback may then help you in refining your designs.

Since you have these relatively simple relationships between the pipes' height, width (&length) and reflectivity, you might also try making some diagrammatic and spreadsheet-based studies to get a feeling for how the system works. You could use such studies to guide your modeling in Dialux, and/or to quickly compare results of changing a parameter such as W or r. (It's not so easy for H, since if the heights of the pipes and rooms are linked, the effect of the room height on distribution of light also becomes a factor.)

Regarding your next steps, I would suggest that creating a program for the building at this stage may be too time-consuming (and not necessarily consistent, since the program should also have influenced the shape and orientation of the project.) Instead, you might try just defining some general goals for the light to be made available inside (...with energy loss and/or generation addressed later, if there's time.)

Examples would be:

1) uniform lighting of floor surface;

2) more intense light at center of floor;

3) more intense light at edges of floor;

4) more intense at one end, less at other;

Just these simply stated goals (even without specific, numeric illuminance level requirements) can be quite challenging to achieve, especially at differing times of day and days of year.

Having been asked to assist, I'll be posting commentary on projects and topics from the course, as appropriate. The feedback pertaining to specific projects can also be found at the students' own blogs. They are collected here for convenience and an overview, as well as offering a possible forum for broader discussion.
