Modelling of all non-electronic, non-dynamic elements of a building. Includes visualization models.

Examples of the type of data (open to extension)

• Walls, flooring, ceilings, windows, doors, stairs, pipes and plumbing, electrical wiring, furniture, spaces and ‘holes/voids’, etc.)
• Materials - conductivity, permeability, u and r values, decibel loss.
• Costs
