Calculation example
Example of a school with a ventilated area of 1,500 m2 for 200 students and teachers with a ventilation system that provides a constant air volume (CAV system):
With ventilation volumes and an efficiency that conforms exactly to the BR08 requirements, the efficiency key indicator will be 2.24 W/m2.
If the system runs continually for 10 hours every day, 5 days a week, 45 weeks a year, the electricity consumption key indicator will be 5 kWh/m2/year, which is equivalent to EUR 0.94-1.2 per m2 per year.
