Urban System Concept
Our four engineered products, the underground parking ramp, the multi-storey building, the elevator and the external building wall, are combined into a single parameterized model, which can adapt to various interfaces built within, as well as its urban surroundings. The idea is to have a building, which is adaptable to the users wishes, which can differentiate between following input parameters:
- Utilization (such as schools, apartments, offices, etc.)
- Available lot area (the available lot area in shape and size)
- Storey height
- Number of people using the building.
After selecting the wished input parameters, a model with specific size, height, number of elevators as well as a ramp is generated (the multi-storey building includes walls, windows, elevators and an underground ramp). After this, the model will be evaluated from different high performance criteria, which are implemented in the Dynamo model. Following evaluations will take place:
- Cost of the building per person
- Floor area per window area
- Usability of the elevator
- Stability of the building
Dynamo Integration of the Initial Systems
The initial civil systems were integrated into one single dynamo parameterized system. The multi-storey building was used as the base model for this development, and the other three systems were integrated within. In the following section, a description of how the dynamo model operates will be presented.
The dynamo script starts with a polygon and from that it creates a wall; the windows are already integrated within the wall (see initial models’ section). The multi-storey building, our base model, gives out the coordinates of the four edges of the building which together with another function, places the walls along these coordinates, as well as in all the storey levels (the amount of storey is pre-set by the inputs parameters, as discussed in the initial models section). Also, functions have been implemented, for creating a slab placed on the ground area of the building (this slab will also serve as the roof of the underground parking), as well as a slab used as the roof. The underground parking will also receive walls, but without windows.
Then, the model will be orientated having its longer side always on the main axis, since the underground parking ramp will be placed on this side. The ramp width will create an opening in the underground walls, allowing an entrance into the building. Its depth is parameterized by the wall heights.
Then, with another function, the number of elevators is generated, this depends on input parameters such as number of people using the building, as well as the utilisation. Once we have the number of elevators, an array with x- and y-coordinates list the walls with a specific number n of elevators placed on them. The elevator shafts will then be placed into the building, with a maximum of four elevators, in this case one per edge of the building. If for instance only three elevators are needed, these will then be placed along the walls with a regular distance between them.
After having integrated all the systems, an evaluation of the parameterized model takes place. The user decides the values of the input parameters, and following HPC evaluate the model (see the initial model section for explanations on the HPC):
- Total costs for envelope
- Summer thermal insulation
- Stability h/b
- Stability A/h
