for our CS project we would like to implement option 2. The difficulty I have is that the building was constructed in the early 90ties and only little information on the existing parts is available. Unfortunately I have no proven VLT for the calculations. In addition windows literally run all around the house on every storey, but they all do have blinds on the outside, which can be operated individually.
Would it still be possible to achieve the ICQc 8.1 via option 2 or would we be forced to measure the whole building?
