Healthy indoor environment in schools, kindergartens and offices
The team of TANGRA has been working for over 10 years on decentralized energy-saving ventilation units in schools and kindergartens across Europe. The company’s devices are installed in educational buildings in Portugal, Czech Republic, Poland, and Switzerland. Based on the experience and the need for fresh and filtered air, especially where it matters the most – for our children, we have created a range of devices for decentralized ventilation.
TANGRA EVB School units provide fresh, filtered, and temperature-controlled air to a room without the need for additional ventilation components (ductwork, ventilation grilles, etc.). They can be equipped with an air quality sensor. The fresh air is automatically regulated based on the occupants’ needs while monitoring parameters for maximum energy efficiency.
TANGRA EVB School offers exceptional freedom to investors, owners, facility managers, architects, and HVAC equipment installers.
Researchers in Denmark have conducted a study on the socio-economic impact of implementing ventilation systems in schools. Thanks to reduced illnesses and absences among both students and teachers, as well as parents, scientists have calculated that investments in improving the microclimate in schools and kindergartens have an effect both in the present, with fewer abscesses and less expenses from the healthcare budget. And also in the long term, because students retain more information and are more successful as adults, leading to a higher GDP for the country.
What is necessary for the good education of children ?
֎ A productive and sustainable learning system;
֎ Ambitious and caring parents;
֎ Well-prepared and motivated teachers;
֎ Cozy and well-lit classrooms;
֎ Comfortable microclimate conditions;
TANGRA EVB School decentralized ventilation devices are designed to provide a high-quality and cost-effective solution for fulfilling the last requirement.
What are the advantages?
֎ Better concentration and knowledge retention:
A Danish study suggests that mathematical problems could be solved up to 14% faster and more efficiently in a better microclimate.
֎ Improved health for children;
What is the European experience?
֎ In Northern and Western European countries, good air quality is mandatory both for new classrooms and existing ones.
֎ In Germany, France, and Scandinavian countries, school classrooms and those in kindergartens must provide a minimum amount of fresh, filtered, and conditioned air of 25m3/h per child.
Why in schools and kindergartens, ventilation systems with energy-saving should be installed?
The answer is simple – fresh filtered air largely prevents the spread of viruses and provide better microclimate for children and teachers.
The range include 3 models with airflow from 150m3/h up to 1000m3/h:
TANGRA EVB School H for horizontal installation, under windowsill;
TANGRA EVB School V for vertical installation, as stand-alone unit;
TANGRA EVB School CL for Ceiling installation.
All units are equipped with counter-flow plate heat exchanger TANGRA REC HiE with efficiency above 79% and certified by Eurovent.
Units in production
TANGRA EVB School H/V/CL are designed in accordance with VDI 6040: Even only 1 unit can provide the necessary fresh and filtrated air in classroom with 25 children, in order to maintain the СО2 concentration below 1000ррм.
The team of TANGRA is entirely at your disposal for any advices and consultations on using selection the software or on making the right design decisions for ventilation systems. Technical data sheets for HRUs or AHUs, Mollier h-x diagrams, and DWG files will be provided to HVAC designers and partners.
Ventilation in the school costs 36 stotinki per child per day!
