Electric vehicle charging in hospital: what the SRI measures
Charging is about three things: how many parking spaces have a charging point, whether charging is managed smartly on grid capacity and price, and whether users get information on availability and consumption.
In short
- 1This page explains how the Smart Readiness Indicator assesses electric vehicle charging at hospitals.
- 2The charging domain counts as one of the three main weighting factors the Smart Readiness Indicator uses for this building type.
- 3Hospitals almost always exceed the 290 kW threshold above which the Smart Readiness Indicator is expected to become mandatory.
Weight of this domain for this building type
Which services count
| Service | Lowest level | Highest level | Advice |
|---|---|---|---|
| EV Charging Capacity EV-15 · A · 5 levels | Not present | > 50% of parking spaces has recharging point | at least level 1 |
| EV Charging Grid balancing EV-16 · A · 3 levels | Not present (uncontrolled charging) | 2-way controlled charging (e.g. including desired departure time and grid signals for optimization) | at least level 1 |
| EV charging information and connectivity EV-17 · A · 3 levels | No information available | Reporting information on EV charging status to occupant AND automatic identification and authorization of the driver to the charging station (ISO 15118 compliant) | at least level 1 |
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 3 percentage points (from 33 to 36 percent, with all other domains at level 1).
What does the Smart Readiness Indicator measure for electric vehicle charging?
The Smart Readiness Indicator (SRI) assesses three smart-ready services in this domain. Each service examines a different aspect of electric vehicle charging on the building site.
The first service, EV-15, measures how many parking spaces actually have a charging point. The second service, EV-16, checks whether charging is controlled intelligently based on grid capacity. The third service, EV-17, concerns information and connectivity towards the user.
Why is this domain relevant for a hospital?
A hospital typically has a large and constantly occupied car park, with staff, visitors and service vehicles. This creates structurally high demand for charging points, which directly affects the EV-15 score.
Hospitals often already have backup power systems and energy storage due to continuity requirements in healthcare operations. That infrastructure makes it technically simpler to also implement bidirectional charging control (EV-16), where vehicles not only draw power but can also return it to the grid.
Because a hospital almost always significantly exceeds the 290 kW HVAC capacity threshold, the building is expected to fall under the future obligation for the Smart Readiness Indicator in non-residential buildings.
How does this domain count towards the overall score?
For hospitals, the electric vehicle charging domain has a weighting factor of 1 on a scale of 3 domains that carry the most weight. This represents average weighting across the nine domains of the methodology.
Each service is assessed at a functionality level from 0 to 4, depending on the service. These levels are then tested against seven impact criteria, including energy efficiency and user convenience, before they count towards the final result.
The building's final score falls into one of seven classes, ranging from below 20 percent to 90 to 100 percent. The charging domain contributes to this alongside the other eight Smart Readiness Indicator domains.
What this means for you
- Owner
- As the owner of a hospital, it makes sense to link existing backup power and storage systems to the charging infrastructure, enabling controlled and potentially bidirectional charging. This not only raises your Smart Readiness Indicator score but also prepares the building for the expected obligation above the 290 kW threshold.
- Tenant
- For hospital staff and visitors, what matters most is whether sufficient charging points are available and whether they receive clear information about charging status and availability. A higher functionality level means shorter wait times and better insight into energy consumption.
- Advisor
- When assessing a hospital, it is important to accurately establish the percentage of parking spaces with a charging point, as this directly determines the EV-15 level. Also check whether the control system genuinely supports bidirectional charging, since this delivers a higher level than one-way controlled charging alone.
