Description
The two custom nodes I made were solar analysis and water view directness. The solar analysis is straightforward. It calculates the cumulative insolation for each form and then gives it a score between 0 to 1, with 1 being the most desirable.
The water view directness node was made to see how many points in the building would have a view of the water. Having a good water view is something potential tenants would like and would pay more money for. So, the water front is represented by the large blue wall in revit. I set up the node to test how many sight lines intersect with that wall, and thus have a view. However, there is also a nearby building in the way. So, after I filtered out the sight lines that did not have a water view, I tested which ones would be blocked by the building, and filtered those out as well. The score is an average of the strength of the water view across the building for each form.
After exporting the list of evaluation criteria to excel, I used excel to set up my evaluation tool for the best building form. The cells highlighted in blue are all the values that are exported from Dynamo. The top height and base width are the two paramters that were flexed. The inputs for these parameters were chosen because they meet the criteria for maximum height of 750 feet and a max base of 300'x450'. For the gross floor area, the criteria given is that its between 1.2 and 1.5 million, which not all of my building forms met. So, an if statement was used in column H. If the floor area does not fall between the criteria, the score is 0. If it does, the floor area is divided by 1.5 million, the maximum area that could exist there. For the surface area score, the criteria is to minimize the building envelope, so that formula is 1 minus the ratio of surface area/maximum surface area of all choices. Then, the water view and solar insolation were already scored in revit, using the remap node to reassign the values from 0 to 1.I then gave each score a weight based on what value I think each brings to the building. Floor area highly affects construction costs and amount of money the building will bring in, which is why it is so high. The water view score is also key because the more apartments that have views, the more people will buy them. So, the weighted score are then added up to evaluate. Only three will actually meet the gross floor area requirement here, so those three will be considered, and ultimately I would choose the one that had the highest score for my evaluation tool. So, a top height of 650' and base width of 375'.
