Abstract

Software that uses actual, historic building management system (BMS) data and/or machine logic to estimate an amount of energy that would have been consumed (and saved) had the BMS been operated under the control of an energy management system (EMS). The software performs the following steps: (i) receiving first actual BMS information relating to operation of a first set of appliance(s) located in a first building during a first time interval; (ii) selecting a first proposed EMS rule set; and (iii) determining a first contrafactual energy resource use value based, at least in part, on the first actual BMS information, with the first contrafactual use value corresponding to an amount of energy resources that would have been consumed by the first set of appliance(s) if the BMS had operated the first set of appliance(s) under control of the first proposed EMS rule set.

Claims

1. A method comprising:

receiving first actual building management system (BMS) information relating to operation of a first set of appliance(s) located in a first building during a first time interval;

selecting a first proposed energy management system (EMS) rule set, wherein the selecting of the first proposed EMS rule set includes determining, by a machine-logic-based knowledge base, a first applicable EMS rule set, wherein each applicable EMS rule of the first applicable EMS rule set relates to at least one first type of BMS information that is detected by a first type of BMS equipment that is installed in the first building, and wherein the selecting of the first proposed EMS rule set further includes determining, by the machine-logic-based knowledge base, a first extensible EMS rule set, wherein each extensible EMS rule of the first extensible EMS rule set relates to at least one second type of BMS information that is detected by a second type of BMS equipment that could be installed in the first building, but is not installed in the first building; and

determining a first contrafactual use value based, at least in part, on the first actual BMS information, wherein the first contrafactual use value corresponds to an amount of one or more energy resources that would have been consumed by the first set of appliance(s) if the BMS had operated the first set of appliance(s) under control of the first proposed EMS rule set, wherein the determining of the first contrafactual use value includes estimating, by the machine-logic-based knowledge base, first estimated BMS values, wherein the determining of the first contrafactual use value depends in part upon the first estimated BMS values, and wherein the first contrafactual use value is an estimated value due to the use of estimated BMS values in the determination of the first contrafactual use value.

2. The method of claim 1 wherein:

the estimated BMS values relate to at least one of the following types of BMS information;

asset type, data point type, weather conditions, building size, building structural features, thermal properties of the building'"'"'s structure, room temperature, room humidity, room barometric pressure, building occupancy, room occupancy, on/off status of the first set of appliance(s), settings status of the first set of appliance(s), energy usage rate(s) of the first set of appliance(s), extent of discretionary use of the first set of appliance(s) by building occupants, timing of discretionary use of the first set of appliance(s) by building occupants, and/or data consumption by the first set of appliance(s).

3. The method of claim 1 further comprising:

identifying BMS equipment that is required to perform under the first proposed EMS rule set.

4. The method of claim 1 wherein:

the knowledge base estimates the first estimated BMS values based on at least one of the following;

historical data for the first building, historical data for buildings other than the first building, a computer simulation of building behavior, use of physics-related mathematical equations, use of statistics-related mathematical equations, observational data, and/or pre- programmed knowledge.

5. The method of claim 1 wherein:

the first set of appliance(s) include at least one of the following appliance types;

lights, light shades, heaters, coolers, ventilators, humidifiers, doors, windows, window coverings, locks, fans, pumps, power-operated security systems, elevators, fire systems, refrigerators, microwaves, coffee machines, computers, phones, modems, routers, washers, dryers, and/or industrial equipment.

6. The method of claim 1 wherein:

the first contrafactual use value is expressed in terms of at least one of the following;

energy units, carbon credits, and/or money.

7. The method of claim 1 further comprising:

receiving a first actual use value corresponding to energy actually used by the first set of appliance(s) during the first time interval; and

determining a difference between;

(i) the first actual use value, and (ii) the first contrafactual use value.

8. The method of claim 7 further comprising:

communicating the difference to a potential customer of BMS and/or EMS products.

9. A computer program product comprising a computer readable storage medium having stored thereon:

program instructions programmed to receive first actual building management system (BMS) information relating to operation of a first set of appliance(s) located in a first building during a first time interval;

program instructions programmed to select a first proposed energy management system (EMS) rule set, wherein the selecting of the first proposed EMS rule set includes determining, by a machine-logic-based knowledge base, a first applicable EMS rule set, wherein each applicable EMS rule of the first applicable EMS rule set relates to at least one first type of BMS information that is detected by a first type of BMS equipment that is installed in the first building, and wherein the selecting of the first proposed EMS rule set further includes determining, by the machine-logic-based knowledge base, a first extensible EMS rule set, wherein each extensible EMS rule of the first extensible EMS rule set relates to at least one second type of BMS information that is detected by a second type of BMS equipment that could be installed in the first building, but is not installed in the first building; and

program instructions programmed to determine a first contrafactual use value based, at least in part, on the first actual BMS information, wherein the first contrafactual use value corresponds to an amount of one or more energy resources that would have been consumed by the first set of appliance(s) if the BMS had operated the first set of appliance(s) under control of the first proposed EMS rule set, wherein the determining of the first contrafactual use value includes estimating, by the machine-logic-based knowledge base, first estimated BMS values, wherein the determining of the first contrafactual use value depends in part upon the first estimated BMS values, and wherein the first contrafactual use value is an estimated value due to the use of estimated BMS values in the determination of the first contrafactual use value.

10. The computer program product of claim 9 further comprising:
