Abstract

Techniques for managing one or more buildings, including collecting historical building data, real-time building data, historical exogenous data, and real-time exogenous data and receiving the collected data at an adaptive stochastic controller. The adaptive stochastic controller can generate at least one predicted condition with a predictive model. The adaptive stochastic controller can generate one or more executable recommendations based on at least the predicted conditions and one or more performance measurements corresponding to the executable recommendations.

Claims

1. A method for managing one or more buildings, comprising:

collecting historical building data, real-time building data, historical exogenous data, and real-time exogenous data;

receiving the collected data at an adaptive stochastic controller; and

with the adaptive stochastic controller;

identifying trends based on the collected data of the one or more buildings;

generating at least one of a predicted condition with a predictive model;

generating one or more executable recommendations based on the predicted condition and one or more performance measurements corresponding to the executable recommendations;

displaying on a graphical user interface the one or more trends based on the collected data of the one or more buildings, the one or more predicted conditions, and the one or more executable recommendations; and

generating suggestions to an operator via the graphical user interface to manually steer a floor condition of the said one or more buildings in response to the one or more trends, predicted conditions, or executable recommendations displayed on the graphical user interface.

2. The method of claim 1, further comprising communicating with the one or more buildings'"'"' HVAC systems to automatically steer the floor condition of the said one or more buildings in response to the one or more trends, predicted conditions, or executable recommendations displayed on the graphical user interface.

3. The method of claim 1, wherein the predicted condition includes at least one of the group of predicted space temperature, supply air temperature, chilled water temperature, electric load, steam consumption or fuel consumption.

4. The method of claim 1, wherein generating the at least one predicted condition includes predicting floor-by-floor occupancy and energy usage over multiple floors. The method of claim 1, wherein collecting further comprises receiving from a building management system the historical building data, real-time building data, historical exogenous data, and real-time exogenous data, and wherein the historical building data and the real-time building data includes electric data, fuel and steam data, space temperature information, air flow rate data, chilled water temperature data, supply air temperature information, return air temperature information, lighting sensor data, elevator data, carbon dioxide data, and HVAC system control data.

5. The method of claim 1, wherein collecting further comprises querying one or more databases including the historical building data, real-time building data, historical exogenous data, and real-time exogenous data.

6. The method of claim 1, wherein collecting further comprises receiving over a network at least one of the historical exogenous data and the real-time exogenous data, and wherein the historical exogenous data and the real-time exogenous data include at least one of historical weather data, forecast weather data, and power grid data.

7. The method of 1, further comprising identifying trends in the one or more building conditions and generating a predicted condition for each building condition, and displaying the identified trends and the predicted conditions, whereby an operator is alerted when an anomaly between the predicted conditions and the building conditions arises.

8. The method of claim 7, wherein the one or more building conditions include space temperature at each measurement location of each floor in the one or more buildings.

9. A method for managing one or more buildings, comprising:

collecting historical building data, real-time building data, historical exogenous data, and real-time exogenous data;

with the adaptive stochastic controller;

generating at least one of a predicted condition with a predictive model;

generating one or more executable recommendations, which includes generating at least one of a recommended start-up time and ramp-down time for a HVAC system based on at least the trends in the one or more building conditions; and

generating a one or more preheat conditions.

10. The method of claim 9, wherein generating one or more executable recommendations further includes generating at least one of a recommended start-up time and ramp-down time for a HVAC system based on at least the trends in the one or more building conditions, the predicted conditions, and the performance measurements.

11. The method of claim 9, wherein generating the one or more preheat conditions includes reducing costs of steam and electricity consumption determined by applying the collected data and the one or more predicted conditions to a dynamic programming or approximate dynamic programming model.
