At Thermacon, we believe every child and teacher has the right to a healthy learning environment. A fresh classroom is essential for optimal concentration and strong performance. With Caladair's innovative, sustainable, and highly comfortable ventilation systems, we realize this effortlessly for your school.
Although figures from the Netherlands Enterprise Agency (RVO) show that air quality, temperature control, and daylight in many Dutch classrooms can still be significantly improved, we see this primarily as an opportunity. An opportunity to invest in the health and future of our youth.
By proactively addressing problems such as excessive CO2 levels, particulate matter, winter drafts, or summer overheating, we transform every classroom into a vital place to learn.
To guide school boards and municipalities in new construction or renovation projects, the RVO has established the Fresh Schools Program of Requirements (PoR). This PoR aligns closely with the Building Regulations and assesses the indoor climate on five crucial themes: energy, air, temperature, light, and sound.
Within the program, three quality levels (ambition levels) are distinguished:
| Criterion | Class C (Sufficient) | Class B (Good) | Class A (Excellent) |
| Fresh air | 21.6 m³/hour per person CO2 < 1200 PPM Maximum 5% leakage Particulate filter 70-80% | 30.6 m³/hour per person CO2 < 950 PPM 100% separation Particulate filter 70-80% | 43.2 m³/hour per person CO2 < 800 PPM 100% separation Particulate filter 80-90% |
| Temperature | Control per room Minimum 19°C Maximum 27°C | Control per room Minimum 20°C Maximum 26°C | Control per room Minimum 21°C Maximum 25.5°C |
| Sound | Maximum 35 dB(A) | Maximum 33 dB(A) | Maximum 30 dB(A) |
| Quality assurance | Remote monitoring | Remote monitoring | Remote monitoring |
Do you want to renovate an existing classroom and upgrade to Fresh Schools Class C or B? Because every school building and project is unique, we believe in customization. Thermacon supports you as an installer or installation engineering consultant throughout the entire process.
