BUILDING MODEL WITH VIRTUAL CAPTURE OF AS BUILT FEATURES AND OBJECTIVE PERFORMANCE TRACKING

1 - 20 . (canceled)

21 . A system of tracking attainment of a stated Objective relating to a residential structure, the system comprising;

a) a global positioning system device positioned proximate to the residential structure;

b) a processor in logical communication with the global positioning system;

c) an altimeter to calculate an elevation of a point of measurement;

an electronic sensor to measure a first state within the residential; and

d) a digital storage additionally in logical communication with said processor and storing code executable on demand to cause the processor to:

determine a geographic position of the residential structure based upon a geospatial determination of the global positioning system device proximate to the residential structure;

identify a digital model of the residential structure based upon the geographic position of the residential structure, the digital model comprising virtual representation of structural components included in the residential structure;

reference multiple positioning reference devices within the residential structure;

measure a distance to at least three of the multiple positioning reference devices from a point of measurement;

calculate a position within the residential structure, a calculation based upon a relative distance of the at least three positioning reference devices to the point of measurement and a triangulation calculation;

specify a location of the first state within the residential structure via reference to the position of the point of measurement and the elevation of the point of measurement;

record a first time designation for the step of measuring the first state within the residential structure, and

correlate the first state within the residential structure and the first time designation with attainment of the stated Objective.

29 . The system of claim 26 wherein at least one of the first state and second state within the residential structure comprises a measurement of electrical current supplied to equipment installed in the residential structure.

30 . The system of claim 26 wherein at least one of the first state and second state within the residential structure comprises a number of cycles of operation of equipment installed in the residential structure.

31 . The system of claim 26 wherein at least one of the first state and second state within the residential structure comprises a number of cycles of operation of an appliance installed in the residential structure.

32 . The system of claim 26 wherein at least one of the first state and second state within the residential structure comprises measurement of electrical current to an appliance installed in the residential structure.

33 . The system of claim 26 , wherein at least one of the first state and second state within the residential structure comprises a vibration associated with movement of an occupant of the residential structure.

34 . The system of claim 33 , additionally comprising a sensor for recording a vibration pattern associated with movement of a specific person within the structure and a storage for storing a movement pattern of the specific person through the structure based upon the sensor for recording a vibration pattern measurements.

35 . The system of claim 33 , additionally comprising a sensor for recording a vibration pattern associated with a particular activity.

36 . The system of claim 26 wherein the state within the residential structure comprises a heat sensor scan of a portion of the residential structure.

37 . The system of claim 36 wherein the state within the heat sensor scan of the portion of the residential structure comprises an infrared scan.

38 . The system of claim 26 wherein the Objective comprises operating the residential structure for a term of years within a threshold use of energy.

39 . The system of claim 26 wherein the Objective comprises operating the residential structure for a term of years within a threshold number of repairs.
