Teachers from Neofit Rilski and Hristo Maksimov Primary School in the Municipality of Samokov and the 56th Primary School "Konstantin Irechek" and 79th Indira Gandhi Primary School in Lyulin District of Sofia Municipality together with representatives of both municipalities took part in a study trip to Berlin as part of the project "Climate Protection through Energy Efficiency - Introducing Models for Stimulating Energy Savings in Schools in Romania and Bulgaria". Participants in the study had the opportunity to get acquainted theoretically with the essence of climate change and energy efficiency, as well as to visit a school in Berlin to witness the direct involvement of pupils in the energy saving process.

The project was implemented in partnership between the NTEF, the German UfU independent environmental institute and the Romanian Environ organization, with the support of the German Federal Ministry of the Environment. It aims to raise awareness among students about energy efficiency and to encourage them to save energy in schools.

On April 26, 2017, a conference was held within the framework of the Climate Conservation Project through Improved Behavior of Energy Users in European Schools, implemented by the National Trust EcoFund in partnership with the Independent Environmental Institute in Berlin with the financial support of the German Ministry of the Environment environment, nature conservation, construction and nuclear safety.

The purpose of the conference was to present the experience of the participating schools and to discuss the future of the project as well as the future involvement of new participants.

Participants in the conference were representatives of the municipalities involved in the project, teachers and pupils, municipalities where the NTEF has funded energy efficiency measures in schools or is about to fund such, NGOs and school representatives, who have implemented other climate change projects.

Representatives of 25 schools from 13 settlements took part. Some of them became familiar with the project for the first time and have already expressed their interest and wish to take part in it.

On March 28, 2018, the second and Final Project Conference was held on the basis of improved behavior of energy users in European schools, implemented by the National Trust EcoFund in partnership with the Independent Environmental Institute in Berlin, with the financial support of the German Ministry of the environment, nature conservation, construction and nuclear safety

Mrs. Irena Georgieva, Chairman of the Board of NTEF, Mrs. Boryana Kamenova, Director of the Climate Change Policy Directorate, Mrs. Lilyana Drumeva, Advisor to the Minister of Education and Science, Mrs. Anja Krechting of the Federal Ministry of Education and Science, participated in the official opening of the conference. the environment of the Republic of Germany, the mayors of Lyulin district in Sofia Milko Mladenov and the municipality of Samokov Vladimir Georgiev.

Participants are the project partners from the Independent Environmental Institute in Berlin and the Romanian non-governmental organization Environ, directors, teachers and pupils from the four schools implementing the project - two from Samokov and two from Lyulin district in Sofia, lecturers at Sofia University participating in the programs of the National Training Center for Pedagogical Specialists, representatives of several other schools that the NTEF has funded to improve the energy efficiency of their buildings.

The purpose of the conference was to present at the end of this project the experience of the participating schools and to outline the prospects for implementing this initiative in more Bulgarian schools. In this sense, the conference is not conclusive, but it makes sense to launch a broad initiative to use the experience of these several pilot activities and implement it in all schools that receive funding to improve their buildings.

The students showed how they measure the temperature and illumination in their school, how they check windows, doors and radiators and how they train their classmates and teachers. They showed how much energy was saved as a result of the activity of the specially formed energy teams.

Measuring instruments used in the energy saving project

Fast measuring thermometer

  • measures the temperature quickly
  • the sensor is at the end of the wire
  • the sensor is fragile; if the students are not careful with it, there is a danger of it being broken
  • it is necessary that the two small wires touch each other
  • measures as soon as it switched on
  • is kept away from the body so that body temperature does not affect the measured value
  • it is necessary to measure in the middle of the room to capture the average room temperature
  • should not be kept too close to the ground because the most accurate value is obtained from the position of average height of the room
  • 20-22 ° C is a suitable room temperature


  • measures illumination
  • the luxometer has different levels; when switched on, a level must be selected
  • the first level (200 lux) is appropriate in a not very lighted room or away from the window
  • when you are closer to the window it is necessary to include a wider measurement level (2000 lux)
  • when you are in a really lighted room, you have to increase the level even more
  • the project focuses on the illumination of pupils' classrooms to guide them to switch lights on only when needed
  • 300 lux is the required level of illumination for the pupils' desks

Carbon dioxide (CO2) measuring instrument

  • measures the amount of CO2 in the air in parts per million (ppm)
  • plug into the power supply and start measuring after a short signal
  • for better measurement, it is advisable not to place it in a corner of the room
  • in order not to disturb the measured value, it is necessary not to place your head too close to the device and not to breathe directly into it
  • it is not necessary to place it in the center of the room
  • when the measured value in the classroom reaches 2000 parts per million, it is necessary to open a window
  • the device is used to demonstrate how quickly the air in the room can be polluted and what is the most effective and energy-saving way of ventilating


  • measures the power consumption of a device
  • students are often unaware of the power consumption of certain devices
  • a number of measurements will give them an idea of the amount of electricity a device consumes

Data logger

  • measures the temperature over a long period of time and stores the values
  • used to measure the average temperature and whether the temperature drops during the night, weekends and during holidays
  • the aim is to identify the potential for saving energy from heating
  • data can be read by free computer software
  • the data should extend to at least one week, along with the weekend - it is even better to include data measured during a vacation


  • to replace the batteries, you need a small screwdriver
