## A 

### AI Controls

The use of smart algorithms to automate systems; [AI Apps](https://glossary/#app). They run on different [components](https://glossary/#component) for different purposes.

### Analysis function

An analysis function is a generic function to determine a specific analysis output. An analysis function takes arbitrary many [pins](https://glossary/#pin) of a [component data model](https://glossary/#component-data-model) and variable time spans as inputs. An analysis function can be designed for a specific component or be applicable on several components.

### Analysis result

The output generated by an [analysis function](https://glossary/#analysis-function) based on the input component data and time spans. An analysis result represents specific insights, metrics, or conclusions derived from the data analysis, such as performance trends, efficiency rates, error patterns, or predictive outcomes. The result is often tailored to the component(s) analyzed and may vary depending on the scope and design of the analysis function.

### App

A controls app uses [algorithms](https://glossary/#%2Econtrols-algorithms) to analyze input data, make decisions, and optimize system operations to achieve specific goals, such as improving efficiency, reducing costs, or enhancing performance.

### Asset

They are the basis for [analysis results](https://glossary/#analysis-result), component design and calculations.

### Datapoint key

Datapoint keys define the naming structure of [datapoints](https://glossary/#datapoint) enabling standardization, translations, and compliance with naming conventions like BUDO.

### Instanced component

An instanced component is a [component data model](https://glossary/#component-data-model) instanced for a specific [project](https://glossary/#project) and it is associated to exactly one project. The [pins](https://glossary/#pin) of the component data model it is instanced from may be mapped to the [datapoints](https://glossary/#datapoint) of the project. Meta data [tags](https://glossary/#tag) may be added to an instanced component to further individualize it.

## K 

### Key figures

Key figures refer to the primary and most critical data points that an [analysis function](https://glossary/#analysis-function) processes and evaluates.

## M 

### Mapping

Mapping is the process of individualizing an [instanced component](https://glossary/#instanced-component).

## S 

### Savings

refer to the reduction in energy consumption and associated costs achieved for an asset through optimization measures or operational improvements. They can be **realized**, meaning successfully implemented and already achieved, or **open**, representing potential savings that have yet to be realized and are often presented as actionable recommendations. The **optimization factor** is a metric used to quantify the efficiency of these measures, typically expressed as a percentage or ratio comparing baseline and optimized performance.

### Setpoint

A setpoint is a predefined or adjustable target value for a specific parameter in a building’s system (e.g., temperature) that guides the operation of equipment or [components](https://glossary/#component). It serves as a reference for optimizing performance, ensuring efficient system operation, occupant comfort, and alignment with operational goals.
