The motivation to take part to the competition

The nature of their work. They realize the necessity of sustainable development in all aspects of the national economy and tried to put it into practice starting with their office. They wanted to improve their working environment and to save money. The Competition was a good chance to do it. The energy audit also was highly appreciated by them and all of the low-cost measures laid in it, occurred step by step in the company`s office. The employees were a team and worked together for the achievement of the goals.

Main energy saving measures implemented

The purchasing of office equipment is by taking into account the energy and environmental performance, energy class, and total consumption in standby mode of the equipment, as well as the presence of internationally recognized labels (Energy Star, EPEAT, etc.). The office equipment (computers, monitors, printers) are used in energy saving mode and if it is technically possible, they are set to turn off automatically when nobody use them.

The company has also adopted flexible working hours with the possibility of working from home and the practice several employees to share common working place that leads to more efficient use of the office space.

The fact that the company organized several campaigns for saving energy on the working place also helped for the good results. A training is done and instructions for the potential of savings in the area had been given to the staff. Instructions and stickers are posted for reminding the employees to turn off the appliances after using them and to switch off the office equipment, appliances and lights before leaving the office.

The temperature in the office varies depending on the outside temperature and according to the preferences of the employees, respecting the adopted rules for optimal temperature in winter and in summer. There are 4 air conditioners installed and used for both cooling and heating.

In the summer and in the autumn of 2015 three out of four air conditioners were replaced with inverter systems of high energy class. It is expected a forthcoming replacement of the last one. That is one of the reasons that led the company to achieve electricity savings as the energy for heating and cooling in the office is mainly for air conditioning. On the other hand the air conditioners are maintained in good working order and are inspected once per year.
