A method and apparatus uses a stored three dimensional model of an object
to render an image showing a condition sensed by a building control
system. The building condition may be sensed by a micro electromechanical
system (MEMS) network that is wirelessly integrated into the building
control system. The three dimensional model may include structural
components, ventilation equipment, safety equipment, furniture and
machinery and allow a user to navigate through the rendered image by
varying the viewpoint of the rendered image.
