Cooling in care building: what the SRI measures
Cooling mirrors heating: control per room, prevent heating and cooling from fighting each other, store cold when electricity is cheap, and let the chiller follow actual demand.
In short
- 1Control of cooling emission, generation and storage.
- 2Weight of this domain for this building type: medium.
- 3If everything in this domain is at level 0, the domain contributes nothing. At the highest level for all services, the indicative total score for this building type rises by about 16 percentage points (from 30 to 46 percent, with all other domains at level 1).

Which services count
| Service | Lowest level | Highest level | Advice |
|---|---|---|---|
| Cooling emission control C-1a · A · 5 levels | No automatic control | Individual room control with communication and occupancy detection | level 2 or higher |
| Emission control for TABS (cooling mode) C-1b · 4 levels | No automatic control | Advanced central automatic control with intermittent operation and/or room temperature feedback control | – |
| Control of distribution network chilled water temperature (supply or return) C-1c · 3 levels | Constant temperature control | Demand based control | – |
| Control of distribution pumps in networks C-1d · 5 levels | No automatic control | Variable speed pump control (external demand signal) | – |
| Interlock: avoiding simultaneous heating and cooling in the same room C-1f · 3 levels | No interlock | Total interlock (control system ensures no simultaneous heating and cooling can take place) | – |
| Control of Thermal Energy Storage (TES) operation C-1g · 4 levels | Continuous storage operation | Cold storage capable of flexible control through grid signals (e.g. DSM) | – |
| Generator control for cooling C-2a · A · 4 levels | On/Off-control of cooling production | Variable control of cooling production capacity depending on the load AND external signals from grid | level 2 or higher |
| Sequencing of different cooling generators C-2b · 5 levels | Priorities only based on running times | Sequencing based on dynamic priority list, including external signals from grid | – |
| Report information regarding cooling system performance C-3 · A · 5 levels | None | Central or remote reporting of performance evaluation including forecasting and/or benchmarking; also including predictive management and fault detection | level 2 or higher |
| Flexibility and grid interaction C-4 · A · 5 levels | No automatic control | Optimized control of cooling system based on local predictions and grid signals (e.g. through model predictive control) | level 2 or higher |
Worked example
If everything in this domain is at level 0, the domain contributes nothing. At the highest level for all services, the indicative total score for this building type rises by about 16 percentage points (from 30 to 46 percent, with all other domains at level 1).
