## Abstract

A method of predicting energy usage having the steps of providing a computer, providing a temperature database, providing a building asset rating database, receiving inputs from a user having a floor area measure of a building, an energy usage measurement, an energy usage start date, an energy usage end date, and a geographic location identifier, determining an estimated energy rating as a function of said inputs, said temperature database, and said building asset rating database, and providing said estimated energy rating to calculate an energy value adjustment for the price of the building.

## Claims

### Claim 1

A method of predicting energy usage comprising the steps of:
providing a computer;
providing a temperature database;
providing a building asset rating database;
receiving inputs from a user comprising:
a floor area measure of a building;
an energy usage measurement;
an energy usage start date;
an energy usage end date;
and a geographic location identifier;
determining an estimated energy rating as a function of said inputs, said temperature database, and said building asset rating database; and providing said estimated energy rating to said user.

### Claim 2 (depends on 1)

The method as set forth in claim 1, wherein said temperature database comprises data records having said geographic location identifier, a temperature, and a date-time.

### Claim 3 (depends on 1)

The method as set forth in claim 1, wherein said geographic location identifier is a zip code.

### Claim 4 (depends on 1)

The method as set forth in claim 1, wherein said building asset rating database comprises building data records having an energy usage measurement, an energy usage start date, an energy usage end date, a geographic location, and an asset-based energy rating.

### Claim 5 (depends on 4)

The method as set forth in claim 4, wherein said asset-based energy rating is a Home Energy Rating Score rating.

### Claim 6 (depends on 1)

The method as set forth in claim 1, and further comprising the step of inserting actual building data into said building asset rating database.

### Claim 7 (depends on 1)

The method as set forth in claim 1, and further comprising the step of calculating an energy value adjustment (EVA) to the market price of the building based on the asset based energy rating and a type of fuel used to heat the building.

### Claim 8 (depends on 7)

The method as set forth in claim 7, wherein a fuel equivalency is calculated based on natural gas as the base line heating fuel standard.

### Claim 9 (depends on 7)

The method as set forth in claim 7, wherein a total heating load for use in a fuel cost adjustment calculation is based on the normalized energy load (NEL) for a time period equal to a predetermined length of ownership.

### Claim 10 (depends on 9)

The method as set forth in claim 9, wherein the length of ownership is based on a calculated average.

### Claim 11 (depends on 9)

The method as set forth in claim 9, wherein the total heating load for the time period is used to calculate the cost difference between different fuel types.

### Claim 12 (depends on 11)

The method as set forth in claim 11, wherein the EVA is applied to the present value of the building based on future energy costs calculated over the time period.

### Claim 13

A method of predicting energy usage comprising the steps of:
providing a computer;
providing a temperature database;
providing a building asset rating database;
receiving inputs from a user comprising:
a floor area measure of a building;
an energy usage measurement from a heating bill;
an energy usage start date from the heating bill;
an energy usage end date from the heating bill;
and a geographic location identifier;
determining an estimated energy rating as a function of said inputs, said temperature database, and said building asset rating database; and providing said estimated energy rating to said user; and
wherein said step of determining an estimated energy rating as a function of said inputs comprises the steps of: calculating the number of degree days between said energy usage start date and said energy usage end date for said building data geographic location identifier using data in said temperature database; calculating the energy usage per unit floor area per degree day; correlating the calculated energy usage per unit floor area per degree day with an asset-based energy rating in said building asset rating database.

### Claim 14 (depends on 13)

The method as set forth in claim 13, and further comprising the step of calculating an energy value adjustment (EVA) to the market price of the building based on the asset based energy rating and a type of fuel used to heat the building.

### Claim 15 (depends on 14)

The method as set forth in claim 14, wherein a fuel equivalency is calculated based on natural gas as the base line heating fuel standard.

### Claim 16 (depends on 14)

The method as set forth in claim 14, wherein a total heating load for use in a fuel cost adjustment calculation is based on the normalized energy load (NEL) for a time period equal to a predetermined length of ownership.

### Claim 17 (depends on 16)

The method as set forth in claim 16, wherein the length of ownership is based on a calculated average.

### Claim 18 (depends on 16)

The method as set forth in claim 16, wherein the total heating load for the time period is used to calculate the cost difference between different fuel types.

### Claim 19 (depends on 16)

The method as set forth in claim 16, wherein the EVA is applied to the present value of the building based on future energy costs calculated over the time period.
