A simulation device for simulating images of at least one building includes a
display
(62) for displaying the images; an input (63, 64) for a user to input
data; a memory (65) including a first memory field containing a layout (40)
of the at least one building, which layout (40) contains references to all
the utility spaces forming the layout, together with their performance characteristics,
a second memory field containing a model (50) of the at least one building,
which model (50) contains references to both physical and financial data
of all the components forming the model, a processor (61) for: computing
and showing elevations of and/or sections through the building, working from the
layout of the model; calculating and showing the total expected investment costs
and running costs for the building.
