Dynamic building envelope in school: what the SRI measures
The envelope is dynamic when shading and windows respond automatically: shading that closes in bright sun and opens for free heat in winter, and windows that open for night cooling. Reporting on performance is included.
In short
- 1This page shows how the Smart Readiness Indicator (SRI) assesses the dynamic building envelope domain in schools.
- 2It covers solar shading, windows and reporting that respond automatically to sun, temperature and air quality.
- 3In schools, this domain carries significant weight: two of three possible weighting points, mainly due to long holidays and full classrooms.
Weight of this domain for this building type
Which services count
| Service | Lowest level | Highest level | Advice |
|---|---|---|---|
| Window solar shading control DE-1 · A · 5 levels | No sun shading or only manual operation | Predictive blind control (e.g. based on weather forecast) | level 2 or higher |
| Window open/closed control, combined with HVAC system DE-2 · 4 levels | Manual operation or only fixed windows | Level 2 + Centralized coordination of operable windows, e.g. to control free natural night cooling | – |
| Reporting information regarding performance of dynamic building envelope systems DE-4 · A · 5 levels | No reporting | Position of each product, fault detection, predictive maintenance, real-time & historical sensor data (wind, lux, temperature...) | 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 6 percentage points (from 33 to 39 percent, with all other domains at level 1).
Why does the building envelope count so heavily in schools?
The Smart Readiness Indicator (SRI) is a European measurement method that shows how efficiently a building manages energy and comfort. For schools, the dynamic building envelope domain receives a weighting of two out of three points. This is high compared to other domains.
This weighting reflects how schools operate. Fixed timetables mean predictable occupancy, but also long periods of vacancy during holidays. Automatic solar shading and windows can save energy during these periods without anyone having to intervene.
Additionally, indoor air quality in classrooms is a known concern. Windows that respond automatically to CO2 levels or temperature directly contribute to a healthier indoor climate for students and staff.
Which smart-ready services fall within this domain?
Within this domain, three services are assessed at functionality level, ranging from 0 (no automation) to 4 (fully predictive).
- DE-1 Solar shading control: from manual operation to predictive control based on weather forecasts.
- DE-2 Window opening and closing control: from manual operation to centralised control for night cooling.
- DE-4 Building envelope systems reporting: from no reporting to real-time and historical sensor data on wind, light and temperature.
Many schools still have older installations with time clocks. These typically score at the lowest levels, as they do not respond to current sensor data.
What does this mean for a school's score?
Because this domain carries high weighting, progress here has relatively significant influence on a school's overall SRI score. A school with limited budget can therefore prioritise this domain most effectively.
Even a small step, for example motorised solar shading with sensor control instead of manual operation, noticeably raises the functionality level. This translates into the class in which the school falls.
What this means for you
- Owner
- A school board would be wise to invest in motorised solar shading and window control, as this domain carries heavy weight in the score. Given the limited budgets of many schools, it makes sense to start with the service currently scoring lowest and offering the greatest impact.
- Tenant
- Students and teachers will mainly notice improved indoor climate: less glare in summer, less overheated classrooms and fresher air thanks to automatic ventilation. Outside lesson hours and during holidays, the building envelope often operates independently, without anyone needing to do anything.
- Advisor
- When assessing, pay attention to the difference between installed technology and actual automation, as many schools still have manually operated solar shading despite motorised installations. Also check whether the reporting function (DE-4) includes fault detection and sensor data, as this determines whether maintenance occurs in time.
