# Campus Properties

> Sharing meters across campus and child properties to enable hierarchical reporting.

## **Property Types**

* **Building**: A single physical property.
* **Campus**: A logical property composed of one or more child properties.

## **Meter Relationships**

Meters may be configured to have different relationships to properties.

<Warning>
  Abisko currently only supports campus configurations from ESPM.
</Warning>

* **Owned** meters: Meters that are physically installed on and/or owned by a property. Owned meters can be **in-metric** or **out-of-metric** for the property on which they are located.

  <Note>
    A meter is considered **owned** by the property in which it is created.
  </Note>
* **In-metric** meters: Meters that contribute to a property’s \*\*Whole Building \*\*performance metrics, regardless of ownership.
  * [Click here](/meters/meter-status) to learn more about **in-metric** metrers.

Ownership and in-metric status are independent.

* A property may have meters that are **owned** but not **in-metric** → e.g. a property has a meter located on its premises, but it does not contribute to the calculation of that property's **Whole Building** performance metrics
* A property may have meters that are **in-metric** but not **owned** → e.g. a campus property may have several child properties with meters that are **in-metric** for the campus (see below)

## **Examples: Campus & Child Property Meter Configurations**

An example of a campus with multiple child properties with different meter configurations.

* **Campus A:** The campus property above owns no meters while having 5 **in-metric** meters that are owned across multiple child properties.
  * Campus-level **Whole Building** performance metrics are calculated based on its 5 **in-metric** meters that are owned by its two child properties.
* **Child properties** are managed independently with their own **owned** & **in-metric** meters.
  * **Building 1:** Has 4 owned meters, of which 3 are **in-metric**.
    * Building 1 **Whole Building** performance metrics are calculated based on its 3 **in-metric** meters.
    * Building 1 has also has 3 owned meters that are **in-metric** for Campus A and contribute to the **Whole Building** performance metrics of Campus A.
  * **Building 2:** Has 2 owned meters, of which only 1 is **in-metric**.
    * Building 2 **Whole Building** performance metrics are calculated based on its 1 **in-metric** meter.
    * Building 2 has also has 2 owned meters, both of which are **in-metric** for Campus A and contribute to the **Whole Building** performance metrics of Campus A.
