Abstract

The structure of electrical consumption in Bulgaria is changing dramatically after moving from centralized to market economy. The closure of a number of large industrial factories, removal of state and cooperative enterprises in the field of agriculture, etc. led to increased role of the household systems in the forming of the country energy balance. On the other hand a number of European and national documents require a sharp improvement of the energy characteristics of buildings, which would lead to low energy consumption or to nearly zero-energy buildings.

In the present study the state of this matter in Bulgaria and the possible approaches to reach the requirements of the mentioned documents are discussed.

The country’s regulations have been looked into, including the National plan for nearly zero-energy buildings 2015–2020, based on article 9, paragraph 1 from the Directive 2010/31/EU for energy characteristics of buildings. The size of the building stock, the types and characteristics of buildings have been analyzed. Considering the parameters of solar radiation, the application of photovoltaic arrays, installed on and close to the objects (facade, roof and other types of construction) has been justified. The necessity to change the curriculums related to the training of experts in the field of the new energy-efficiency technologies, including energy management and smart microgrid systems, is pointed out.
