Abstract

An approach for monetizing performance of building system equipment such as HVAC equipment. Expected and actual performance curves may be obtained for the HVAC equipment. Differences between the curves may indicate energy consumption. The energy consumption may be monetized. The monetizing may be of degradation that occurs when the equipment deteriorates, incurs a fault or has a loss of performance as accrued over time. Monetizing may incorporate maintenance and capital risk exposure. The monetizing may be a conversion of analyses of the equipment to money in real time. Performance monitoring of the equipment may incorporate predictive trending which may lead to fault prognosis and preventative maintenance. Automation of the conversion may result in immediate information and feedback to customers. The information may be stored for historical purposes and future analyses.

Claims

1. A method for monetizing performance of building system equipment, comprising:

establishing an expected performance curve of building system equipment;

obtaining an actual performance curve of the building system equipment;

determining a difference between the expected performance curve and the actual performance curve; and

monetizing the difference.

2. The method of claim 1, wherein monetizing the difference comprises:

converting the difference into a quantity of energy consumption; and

determining a cost of the quantity of energy consumption.

3. The method of claim 2, wherein the cost of the quantity of energy consumption is the quantity of energy consumption multiplied by a cost per quantity unit of energy as the cost per quantity unit of energy varies over time.

4. The method of claim 3, wherein the quantity of energy consumption is for a time period of the actual performance curve of the building system equipment.

5. The method of claim 4, wherein the building system equipment is HVAC equipment.

6. The method of claim 1, wherein:

the expected performance curve is for a first time period;

the actual performance curve is over a second time period; and

a length of the first time period is equal to a length of the second time period.

7. A method for monetizing degradation of building system equipment, comprising:

obtaining a first actual performance curve of building system equipment at a first time;

obtaining a second actual performance curve of the building system equipment at a second time;

determining a difference between the first actual performance curve and the second actual performance curve incorporating weather normalization; and

monetizing the difference.

8. The method of claim 7, wherein monetizing the difference comprises:

converting the difference into a quantity of energy consumption; and

determining a cost of the quantity of energy consumption.

9. The method of claim 8, wherein the cost of the quantity of energy consumption is the quantity of energy consumption multiplied by a cost per quantity unit of energy.

10. The method of claim 9, wherein the quantity of energy consumption is for a time period of the second actual performance curve of the building system equipment.

11. The method of claim 9, wherein:

the first performance curve is for a first time period;

the second performance curve is for a second time period; and

a length of the first time period is approximately equal to a length of the second time period.
