Abstract

An online energy audit system poses and collects responses to a list of survey questions regarding a subject house from a remote occupant via a survey UI. Survey responses are stored in an energy-use profile associated with the subject house and are used to populate model inputs to an energy-use software model, from which an energy-efficiency score is derived. To help a remote occupant choose appropriate answers and to facilitate completion of the survey, the survey UI includes question-specific house-feature images associated with some or all questions. Survey questions are designed to be easy for a homeowner to understand, and the survey is kept short. The energy-efficiency score of the subject house is presented to the remote occupant in comparison with comparison energy-use data together with an action message to encourage the remote occupant to improve the energy score of the subject house.

Claims

1. A computer-implemented method for profiling the energy use of a subject house, the method comprising:

obtaining, by the computer, a plurality of survey questions related to a plurality of house characteristics, each of said questions being associated with a plurality of pre-determined answer options;

providing, by the computer via a computer network, a survey user interface (“

UI”

) for posing and collecting responses to said plurality of survey questions, including for each of said plurality of survey questions, providing a question-specific plurality of house-feature images for presentation in said survey UI to facilitate said remote occupant selecting an appropriate answer option for the current question, each house-feature image depicting a representative house feature corresponding to a pre-determined answer option;

collecting, by the computer via said survey UI, a plurality of survey responses from a remote occupant of the subject house, each survey response indicating a selected answer option corresponding to one of said plurality of survey questions; and

storing, by the computer, said plurality of survey responses into a subject-home energy-use profile associated with the subject house.

2. The method of claim 1, further comprising obtaining an energy-use software model having a plurality of model inputs corresponding respectively to said plurality of house characteristics.

3. The method of claim 2, further comprising determining, based at least in part on said survey responses of said subject-home energy-use profile, a plurality of input values to respectively populate said model inputs of said energy-use software model.

4. The method of claim 3, wherein determining said plurality of input values comprises:

obtaining a plurality of predetermined possible input values corresponding to one of said model inputs; and

selecting one of said predetermined possible input values based on at least one of said survey responses.

5. The method of claim 3, wherein determining said plurality of input values comprises obtaining a constant input value corresponding to one of said model inputs, but not corresponding to any of said plurality of survey responses, said constant input value being utilized to reduce the quantity of survey responses that need to be collected to populate said model inputs of said energy-use software model.

6. The method of claim 5, wherein the model input to which said constant input value corresponds is selected from an input group consisting of inputs related to duct leakiness, laundry water use, hot water use other than laundry and shower, and electrical load other than lighting.

7. The method of claim 6, wherein obtaining said constant input value corresponding to one of said model inputs comprises selecting said constant input value from a constant-value group consisting of “

Average” and

“

Low”

.

8. The method of claim 5, wherein obtaining said constant input value corresponding to one of said model inputs comprises automatically obtaining energy-usage data associated with the subject house from an energy-provider device.

9. The method of claim 8, wherein obtaining said constant input value further comprises selecting among a range of predetermined values based at least in part on said automatically-obtained energy-usage data.

10. The method of claim 3, wherein determining said plurality of input values comprises obtaining a survey response indicating a vintage of the subject house, and selecting, based at least in part on said vintage of the subject house, an input value for one of said model inputs from a group of varying input values.

11. The method of claim 3, wherein collecting said plurality of survey responses comprises:

obtaining a survey response to one of said plurality of survey questions;

determining, based at least in part on said obtained survey response, not to ask another of said plurality of survey questions.

12. The method of claim 11, wherein said obtained survey response indicates that the subject house lacks a basement or crawlspace, and wherein the unasked survey question relates to basement or crawlspace air ducts.

13. The method of claim 11, further comprising obtaining an assumed input value corresponding to one of said model inputs and to the unasked survey question, said assumed input value being utilized to reduce the quantity of survey responses that need to be collected to populate said model inputs of said energy-use software model.

14. The method of claim 13, wherein said obtained survey response indicates that the subject house lacks a basement or crawlspace, and wherein said assumed input value assumes that a majority of air ducts of the subject house are in an attic of the subject house.

15. The method of claim 1, wherein for at least one of said plurality of survey questions, said survey UI simultaneously presents each of said question-specific plurality of house-feature images in said survey UI to facilitate said remote occupant selecting an appropriate answer option for the current question.

16. The method of claim 1, wherein said survey UI presents no answer-option-selection controls that require alphanumeric data entry.

17. The method of claim 3, further comprising using said populated model inputs of said energy-use software model to determine an energy-efficiency score for the subject house.

18. The method of claim 17, further comprising:

obtaining a comparison energy-efficiency score for an actual or hypothetical comparison house; and

providing a comparison user interface (“

UI”

) for presenting said energy-efficiency score for the subject house in relation to said comparison energy-efficiency score for an actual or hypothetical comparison house.

19. The method of claim 18, wherein obtaining said comparison energy-efficiency score for an actual or hypothetical comparison house comprises:

selecting a subset of one or more improvable characteristics from said plurality of house characteristics;

from said plurality of survey responses of said subject-home energy-use profile, selecting a plurality of non-improvable responses that are associated with non-improvable characteristics of the subject house;

obtaining one or more idealized responses corresponding to said one or more improvable characteristics of an idealized house; and

generating an improved-home energy-use profile for the subject house according to said plurality of non-improvable responses associated with non-improvable characteristics of the subject house and to said one or more idealized responses corresponding to said improvable characteristics of an idealized house.

20. The method of claim 18, further comprising selecting and presenting an action message in said comparison UI to encourage said remote occupant to improve said energy-efficiency score for the subject house based at least in part on said energy-efficiency score.

21. The method of claim 18, wherein obtaining said comparison energy-efficiency score comprises selecting a plurality of comparison houses that are similar to the subject house with respect to at least one of size, location, and vintage, and that are respectively associated with a plurality of comparison-house energy-efficiency scores.

22. The method of claim 21, wherein providing said comparison UI for presenting said energy-efficiency score for the subject house in relation to said comparison energy-efficiency score comprises ranking the subject house and said selected plurality of comparison houses according to their respective energy-efficiency scores.

23. The method of claim 22, further comprising selecting and presenting an action message in said comparison UI to encourage said remote occupant to improve said energy-efficiency score for the subject house based at least in part on said ranking of the subject house and said selected plurality of comparison houses.

24. The method of claim 18, wherein providing said comparison UI comprises:

determining a mathematical relationship between said energy-efficiency score for the subject house in relation to said comparison energy-efficiency score for an actual or hypothetical comparison house; and
