Abstract

A computer implemented method for 3-D visualization of a building module and building related data includes receiving attributes of a plurality of building modules from a building information model and receiving data inputs from a plurality of sensors located in at least a subset of the plurality of building modules. The building related data is calculated for each of the plurality of building modules based on the data inputs. A 3-D visualization data of a selected building module in the plurality of building modules is generated for display on a computer screen.

First claim

We claim:

1. A computer implemented method of 3-D visualization of a building module and building related data, comprising:
receiving attributes of a plurality of building modules from a building information model;
receiving data inputs from a plurality of sensors located in a selected building module included in the plurality of building modules;
determining a location of at least one sensor included in the plurality of sensors by receiving, from the building information model, X, Y, and Z coordinates of the sensor;
determining that at least one sensor included in the plurality of sensors has failed;
in response to determining that the least one sensor has failed, interpolating or extrapolating the data inputs associated with one or more other sensors included in the plurality of sensors to generate simulated data points;
calculating the building related data for the selected building module based on the data inputs, the simulated data points, and the X, Y, and Z coordinates of the sensor, wherein the building related data is calculated by applying a gradient shading technique to determine, from a 3-D scalar field of data points corresponding to at least the data inputs from the sensors, colors used to shade points on one or more surfaces of the selected building module; and
generating the 3-D visualization of the selected building module based on the attributes and the building related data of the selected building module for display on a computer screen.

2. The computer implemented method of claim 1 , wherein the data inputs are transformed before the calculating.

3. The computer implemented method of claim 1 , further including determining locations of at least a subset of the plurality of sensors, wherein the locations include X, Y, and Z coordinates of each of the subset of the plurality of sensors and the locations of at least the subset of the plurality of sensors are determined through a triangulation method.

4. The computer implemented method of claim 1 , wherein the selected building module is selected by a user from a hierarchical list of the plurality of building modules.

5. The computer implemented method of claim 1 , wherein the calculating is based on a quality of data inputs based on proximity of one or more of the plurality of sensors from to be visualized parts of the selected building module.

6. The computer implemented method of claim 1 , wherein the 3-D visualization includes at least one of a graphical visualization of heat sources, a graphical visualization of heat sinks, a visualization of light sources and a visualization real time power usage.

8. The computer implemented method of claim 1 , wherein the building related data comprises a level of confidence associated with the data inputs, and generating the 3-D visualization comprises rendering at least one area of the selected building module to visualize the level of confidence.

9. The computer implemented method of claim 1 , wherein determining that the at least one sensor has failed comprises determining that connectivity of the sensor to a network has been disrupted.

10. The computer implemented method of claim 1 , wherein generating the 3-D visualization of the selected building module comprises generating a visual representation of a power outlet included in the selected building module, wherein a color of the power outlet is based on a power usage value.

11. A non-transitory computer readable storage medium storing instructions that, when executed by a host computer, cause the host computer to carry out operations to generate, via one or more processors, a 3-D visualization of a building module, the operations including:
receiving attributes of a plurality of building modules from a building information model;
receiving data inputs from a plurality of sensors located in a selected building module included in the plurality of building modules;
determining a location of at least one sensor included in the plurality of sensors by receiving, from the building information model, X, Y, and Z coordinates of the sensor;
