Smart-ready service H-1b · Heating
Emission control for TABS (heating mode)
In short
- 1This page covers service H-1b: the control regulation for TABS in heating mode, part of the Heating domain within the Smart Readiness Indicator.
- 2TABS stands for thermally active building systems, where a building's structure, such as floors or ceilings, is used to emit heat.
- 3This service counts only in the extended method B of the SRI, not in the simpler method A.
The levels
Level 0
No automatic control
Level 1
Central automatic control
Level 2
Advanced central automatic control
Level 3
Advanced central automatic control with intermittent operation and/or room temperature feedback control
What is the control regulation for TABS?
TABS stands for thermally active building systems. These are structures, for example concrete floors or ceilings, that store heat and release it slowly into a space. Because these systems respond slowly, the way heat emission is controlled matters for comfort and energy use.
Service H-1b assesses how intelligently this emission control is set up when the system operates in heating mode. The service falls within the Heating domain of the Smart Readiness Indicator (SRI), the European measurement tool for the digital readiness of buildings.
What functionality levels are there?
The SRI methodology defines four levels for this service, from 0 to 3. Each level represents a higher degree of automation.
- Level 0: no automatic control.
- Level 1: central automatic control.
- Level 2: advanced central automatic control.
- Level 3: advanced central automatic control with intermittent operation and/or feedback based on room temperature.
At level 3, the control responds to how warm the space actually is, and can switch the system off temporarily or adjust it if no longer needed. This makes level 3 more suitable for reducing energy use than the lower levels.
Why does this service count only in method B?
The SRI has two calculation methods: a simple method A with 27 smart-ready services and an extended method B with 54 services. Service H-1b is part of method B only.
This means a building with TABS is assessed on this specific functionality only if the extended assessment method is applied. Under method A, this service does not count towards the final score.
How does this count in the SRI score?
Each smart-ready service is assessed against seven impact criteria, including energy efficiency, comfort and maintenance. These impact criteria are grouped around three key functionalities that each carry equal weight in the calculation.
The result of all services combined leads to a score in percentages, which is placed in one of seven classes, from below 20 percent to 90 to 100 percent.
