Building automation system with a verifiable relationship building language

A building management system of a building for verifying and running a script, wherein the building management system comprises a processing circuit configured to:

• receive the script, wherein the script indicates one or more operations to be performed with one or more data points of a data model of the building;
• determine whether there is unit cohesion within the script, wherein the unit cohesion indicates that a result value of executing the script with the one or more data points comprise result units that match desired units;
• and
• determine the result value by executing the script with the one or more data points in response to determining that there is the unit cohesion;
• wherein the processing circuit is configured to cause building equipment of the building to control an environmental condition of the building based on the result value.

A non-transitory computer readable medium having machine instructions stored therein, the machine instructions being executable by a processor of a dynamically updatable building management system for a building to perform operations, the operations comprising:

• receiving a script, wherein the script indicates one or more operations to be performed with one or more data points of a data model of the building;
• determining whether there is unit cohesion within the script, wherein the unit cohesion indicates that a result value of executing the script with the one or more data points comprise units that match desired units, wherein determining whether there is the unit cohesion comprises determining whether a result unit of the result value is not a unit, wherein the not a unit is a result of adding or subtracting one or more particular values of different units in the script;
• and
• determining the result value by executing the script with the one or more data points in response to determining that there is the unit cohesion:
• wherein the operations further comprise causing building equipment of the building to control an environmental condition of the building based on the result value.
