Abstract

A building energy management includes building equipment, one or more data platform services, a timeseries database, and an energy management application. The building equipment operate to monitor and control a variable and provide raw data samples of a data point associated with the variable. The timeseries database stores a plurality of timeseries associated with the data point. The plurality of timeseries include a timeseries of the raw data samples and the one or more optimized data timeseries generated by the data platform services based on the raw data timeseries. The energy management application generates an ad hoc dashboard including a widget and associates the widget with the data point. The widget displays a graphical visualization of the plurality of timeseries associated with the data point and includes interactive user interface options for switching between the plurality of timeseries associated with the data point.

First claim

What is claimed is:

1. A building system of a building comprising one or more storage devices having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to:
cause a storage device to store a building model comprising a plurality of data entities representing a plurality of entities of the building and a plurality of relationships between the plurality of data entities, wherein each of the plurality of relationships logically defines a relationship between a first data entity of the plurality of data entities and a second data entity of the plurality of data entities with one or more words or phrases, the one or more words or phrases comprising a predicate;
retrieve at least a portion of the building model from the storage device;
generate derived building data based on at least the portion of the building model; and
ingest the derived building data into the building model.

2. The building system of claim 1 , wherein the one or more words or phrases further comprise a preposition.

3. The building system of claim 1 , wherein a third data entity of the plurality of data entities is linked to a fourth data entity of the plurality of data entities by a particular relationship of the plurality of relationships by the particular relationship forming a sentence comprising a first name of the third data entity, one or more particular words or phrases of the particular relationship, and a second name of the fourth data entity;
wherein the first name of the third data entity represents a noun of the sentence, the one or more particular words or phrases of the particular relationship represents a particular predicate of the sentence, and the second name of the fourth data entity represents an object of the sentence.

4. The building system of claim 1 , wherein the plurality of entities of the building comprise at least one of building equipment, spaces, or people.

5. The building system of claim 1 , wherein the one or more processors are configured to:
receive building data from a building data source, the building data representing one or more conditions associated with the building; and
ingest the building data into the building model based on at least the portion of the building model retrieved from the storage device.

6. The building system of claim 1 , wherein the one or more processors are configured to:
retrieve building data from the building model; and
generate the derived building data based on the building data retrieved from the building model and a contextual representation of the building, wherein the portion of the building model retrieved from the storage device is the contextual representation of the building.

7. The building system of claim 1 , wherein the building model is a building graph.

8. The building system of claim 1 , wherein the plurality of relationships are directional relationships each representing the relationship from the first data entity of the plurality of data entities to the second data entity of the plurality of data entities.

9. The building system of claim 8 , wherein each of the directional relationships comprises an indication of a direction from the first data entity of the plurality of data entities to the second data entity of the plurality of data entities, wherein the one or more words or phrases of each of the directional relationships semantically links the first data entity to the second data entity.

10. The building system of claim 1 , wherein one or more of the plurality of relationships are bidirectional relationships, wherein the bidirectional relationships represent a first relationship from the first data entity of the plurality of entities to the second data entity of the plurality of data entities and a second relationship from the second data entity of the plurality of entities to the first data entity of the plurality of entities.

11. The building system of claim 10 , wherein each of the bidirectional relationships comprise:
a first indication of a first direction from the first data entity of the plurality of data entities to the second data entity of the plurality of data entities, wherein the first indication is linked to one or more first words or phrases comprising a first predicate semantically linking the first data entity to the second data entity; and
a second indication of a second direction from the second data entity of the plurality of data entities to the first data entity of the plurality of data entities, wherein the second indication is linked to one or more second words or phrases comprising a second predicate semantically linking the second data entity to the first data entity.

12. A method of building management comprising:
causing, by one or more processing circuits, a storage device to store a building model comprising a plurality of data entities representing a plurality of entities of a building and a plurality of relationships between the plurality of data entities, wherein each of the plurality of relationships logically defines a relationship between a first data entity of the plurality of data entities and a second data entity of the plurality of data entities with one or more words or phrases, the one or more words or phrases comprising a predicate;
retrieving, by the one or more processing circuits, at least a portion of the building model from the storage device;
generating, by the one or more processing circuits, derived building data based on at least the portion of the building model; and
ingesting, by the one or more processing circuits, the derived building data into the building model.

13. The method of claim 12 , wherein a third data entity of the plurality of data entities is linked to a fourth data entity of the plurality of data entities by a particular relationship of the plurality of relationships by the particular relationship forming a sentence comprising a first name of the third data entity, one or more particular words or phrases of the particular relationship, and a second name of the fourth data entity;
wherein the first name of the third data entity represents a noun of the sentence, the one or more particular words or phrases of the particular relationship represents a particular predicate of the sentence, and the second name of the fourth data entity represents an object of the sentence.

14. The method of claim 12 , wherein the plurality of entities of the building comprise at least one of building equipment, spaces, or people.

15. The method of claim 12 , further comprising:
retrieving, by the one or more processing circuits, building data from the building model;
generating, by the one or more processing circuits, the derived building data based on the building data retrieved from the building model and a contextual representation of the building, wherein the portion of the building model retrieved from the storage device is the contextual representation of the building; and
ingesting, by the one or more processing circuits, the derived building data into the building model.

16. The method of claim 12 , wherein the building model is a building graph.

17. The method of claim 12 , wherein the plurality of relationships are directional relationships each representing the relationship from the first data entity of the plurality of data entities to the second data entity of the plurality of data entities;
wherein each of the directional relationships comprises an indication of a direction from the first data entity of the plurality of data entities to the second data entity of the plurality of data entities,
