Begrippen

290-kW-Schwelle

The rated output of heating, cooling or ventilation systems above which building automation is mandatory and above which the SRI is expected to become mandatory.

BACS (Gebäudeautomation)

The system that automatically controls and monitors a building's installations.

Bedarfsgeführte Lüftung

Ventilation that adjusts the airflow to the number of people or measured CO2, instead of always running at full capacity.

Delegierter Rechtsakt

A decision the European Commission may take to supplement a directive.

Domäne

One of the nine parts of a building the SRI assesses: heating, hot water, cooling, ventilation, lighting, envelope, electricity, EV charging and monitoring and control.

EN ISO 52120-1 (früher EN 15232)

The standard that classifies building automation into classes A to D and underpins the BACS requirements.

Energieflexibilität

A building's ability to shift consumption, store energy and respond to grid or price signals.

EPBD (Gebäuderichtlinie)

The European directive setting requirements for the energy performance of buildings.

Funktionalitätsstufe

The scale from 0 (manual) up to 4 (fully automatic and integrated) on which a service is scored.

GACS (Dutch term for BACS)

The Dutch term for BACS.

Gebäudeleittechnik (GLT)

The software and hardware with which a manager centrally monitors and controls all installations.

Gewichtungsfaktor

The weight a domain gets in the total score.

Methode A (vereinfacht)

The simplified assessment with about 27 services, suitable for a quick indication or smaller buildings.

Nationale Testphase

A period in which a member state tries out the SRI voluntarily on real buildings.

Präsenzerkennung

Sensors that register whether people are in a room, so lighting, heating and ventilation can respond.

Schlüsselfunktion

The three main goals of the SRI: energy performance and operation, response to occupants, and energy flexibility.

Smart Readiness Indicator (SRI)

The European method for measuring how well a building controls its installations, responds to occupants and moves with the energy grid.

Smart-ready-Dienst

A concrete function a building can perform smartly, such as occupancy control of lighting.

SRI-Klasse

One of the seven bands the total score falls into: 90 to 100, 80 to 90, 65 to 80, 50 to 65, 35 to 50, 20 to 35 and below 20 percent.

Wirkungskriterium

One of the seven effects on which the SRI scores a service: energy efficiency, maintenance, comfort, convenience, health, information and energy flexibility.
