Heat emission control

What does service H-1a involve?

H-1a concerns the way heat emission in a building is controlled. This includes, for example, radiators, floor heating or other emission systems that deliver heat to a room. The service falls within the Heating domain of the Smart Readiness Indicator (SRI), the assessment framework for the digital readiness of buildings established in Delegated Regulation (EU) 2020/2155.

H-1a is one of the services also used within method A. Method A is a simplified version of the SRI assessment, intended for buildings where less detailed data is available.

What are the functionality levels?

The SRI methodology assigns functionality levels 0 to 4 to each smart-ready service. For H-1a, these levels are as follows:

• Level 0: no automatic control of heat emission.
• Level 1: central automatic control, for example with a central thermostat.
• Level 2: individual room control, for example with thermostatic radiator valves or an electronic controller.
• Level 3: individual room control with communication between controllers and to the building management system (BMS).
• Level 4: individual room control with communication and occupancy detection.

Each level indicates how granular and how intelligent heat emission per room can be controlled. A higher level means more control per room and stronger integration with other building systems.

Why does this service count towards the SRI score?

The SRI assesses smart-ready services against seven impact criteria, such as energy efficiency and comfort. The level of H-1a influences how much a building scores on these criteria within the Heating domain.

A building's final score is expressed as a percentage and classified into one of seven classes, from below 20 percent to 90 to 100 percent. Heat emission control contributes to the overall picture of how intelligently a building manages heating.
