One of the objectives of the World Bank’s Project “Energy Efficiency in BiH” (BEEP) for the Federation of Bosnia and Herzegovina is the confirmation or verification of the expected effects of energy efficiency measures which have been selected through the project implementation. This activity will be realized through Technical Monitoring and Evaluation (TME).
As a prerequisite for achieving this objective, each facility on which the energy efficiency measures are being implemented, got built-in measuring equipment for measurement of the value of important parameters for heating, cooling and ventilation of facilities.
There are currently 28 facilities with built-in equipment, which already have provided us information on the state in these facilities before the implementation of the energy efficiency measures. That information is related to:
Delivered amount of thermal energy for heating of facilities, whereby measurements may be at the minute, hourly, daily, monthly or seasonal record level of measurement results.
Measurement of internal and external temperature and humidity in the three characteristic rooms (according to the purpose), by use of equipment that allows minute, hour, daily, monthly or seasonal (annual) reading of measured values.
By such approach the BEEP offered for the first time a complete and comprehensive model for resolving the issue of energy efficiency. Also, by measuring reports (technical monitoring “before” and “after”) will make quality assumptions to confirm, in other words to verify the expected results after the implementation of energy efficiency measures.
Beside verification and validation of the results of the BEEP Project, data measured and processed through TME will support the goals of the Federation of Bosnia and Herzegovina in terms of savings in energy consumption which are provided by the Action Plan for Energy Efficiency of FBiH (EEAPF), and based on the obligations established by the National Energy Efficiency Action Plan of Bosnia and Herzegovina ( NEEAPs).
“There is no other way to accurately confirm estimates, budgets, analyses and achieved effects of implemented energy efficiency measures of selected scenarios than results obtained by the measurement. For this reason the installation of permanent equipment for monitoring of obtained results is a crucial project to demonstrate the feasibility and viability of the projects of energy efficiency”, Said Mesud Mustedanagić, Technical Expert of the Implementation Unit of the World Bank Project ” Energy Efficiency in BiH ” for the Federation of Bosnia and Herzegovina.
After the implementation of energy efficiency measures, monitoring and measurement of the mentioned items shall be continued for at least two more years in order to get a more objective picture of actual consumption, savings and comfort in facilities.
For the provision of the above-mentioned data, the following equipment has been installed:
Ultrasonic measurer of delivered thermal energy (based on the measurement of the flow of hot water pipelines), battery power for autonomy in the work and independence of supply from the city network, M-Bus modules, integrated in measurers, for storing of measured data as well as sensors for measuring of temperature in starting and return heating system. For the installation it is necessary to predict calorimeter of required diameter of the heating system for each facility.
Data Logger OPUS for “storage” of obtained data, sensors for indoor and outdoor temperature and humidity as well as Y connectors and BUS cables for functional connection of the above mentioned components of the measuring system.
The application program that processes the peripheral data and provides numerical and graphical display of measured values. The results can be read and downloaded on the spot and also it is possible to upgrade the system for remote reading.
