Ventilation in hotel: what the SRI measures
Ventilation is about demand-controlled ventilation: more air when more people are present or CO2 rises, less when a room is empty. Heat recovery, free cooling with outdoor air and air-quality reporting count as well.
In short
- 1Air supply based on occupancy and air quality.
- 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 10 percentage points (from 31 to 41 percent, with all other domains at level 1).

Which services count
| Service | Lowest level | Highest level | Advice |
|---|---|---|---|
| Supply air flow control at the room level V-1a · A · 5 levels | No ventilation system or manual control | Local Demand Control based on air quality sensors (CO2, VOC, ...) with local flow from/to the zone regulated by dampers | level 2 or higher |
| Air flow or pressure control at the air handler level V-1c · 5 levels | No automatic control: Continuously supplies of air flow for a maximum load of all rooms | Automatic flow or pressure control with pressure reset: Load dependent supplies of air flow for the demand of all connected rooms (for variable air volume systems with VFD) | – |
| Heat recovery control: prevention of overheating V-2c · 3 levels | Without overheating control | Modulate or bypass heat recovery based on multiple room temperature sensors or predictive control | – |
| Supply air temperature control at the air handling unit level V-2d · 4 levels | No automatic control | Variable set point with load dependant compensation. A control loop enables to control the supply air temperature. The setpoint is defined as a function of the loads in the room | – |
| Free cooling with mechanical ventilation system V-3 · 4 levels | No automatic control | H,x-directed control: The amount of outside air and recirculation air are modulated during all periods of time to minimize the amount of mechanical cooling. Calculation is performed on the basis of temperatures and humidity (enthalpy) | – |
| Reporting information regarding IAQ V-6 · A · 4 levels | None | Real time monitoring & historical information of IAQ available to occupants + warning on maintenance needs or occupant actions (e.g. window opening) | level 2 or higher |
