Grasshopper

I try to use the grasshopper to help me design. First, I set up a grid structure as a basic system of the new facade, then translate the numbers of humidity, temperature, carbon dioxide concentrations, respectively, as x, y, z axises in Rhino/Grasshopper, each node of the grid is defined as data on different time points. Input the average difference of temperature, humidity, carbon dioxide concentration to each time point. Then the model had been generated.

    Thanks for providing this additional detailed description of the design's input factors and their relationship to the model. As far as I can see, however, the roles of humidity, temperature and CO2 concentrations* are only metaphorical in this model. Or do the deformations shown somehow actually influence the environment(s) other than visually?

    (* by the way, are these indoor values, outdoor values, or ...?)

    Also, the connection between such a scheme and your design alternatives (as shown in the sketches) is not apparent.

    Can you instead relate the effects you consider important (ventilation, shading) to the input factors and show their operation in a model (or models) which represent(s) the variable elements of your design proposals (such as the operable glass fins, the electro- or photo-chromic tree-like patterns, etc.)?

    One very simple example would be a model with two graphs (real or hypothetical) of indoor and outdoor temperature, with the difference in these values linked to an array of louvres whose degree and/or number of open-/closed-ness is driven by that difference. Such a scheme would actually need to account for a number of other factors as well in order to be an accurate model of how this type of facade could operate, but at least you would have a starting point for further elaboration. Also, you could test alternative facade designs using the same control scheme and/or test other control schemes for the same design.

    Dear CHang

    thanks for the update, it is nice to see the parametric model, but I do not see any connection to your previous explorations on the facade layering. Also like Andre posted above, the numbers you use seem to not be used in a technical way in determining the facade points?
    Your previously posted sketches of facade layer options seem promising, it would be great to connect those now back to the measurement data you have from the building and build a parametric model that can help to predict the changes in the humidity, temperature and sunlight by responding to changing inputs.

    We should discuss this in person also, I stopped by today in the BT lab but did not see you, so you are probably working elsewhere, at the latest on monday then during class
