This document discusses energy efficiency activities of the Sustainable Energy Development Agency. It outlines the agency's role in auditing and certifying buildings and industrial systems for energy efficiency, as well as checking hot water boilers and conditioning systems. The agency is responsible for managing energy efficiency in buildings and industry, developing plans and programs, and controlling compliance with energy efficiency obligations. It provides data on energy savings and emissions reductions achieved through various energy efficiency measures implemented in buildings and industrial systems in the country.

investment design of new buildings, building after
reconstruction, renewal, overhaul or
reconstruction with total build-up area of more
than 500 m2 are observed;
 Recommend energy efficiency improvement
measures.

ENERGY EFFICIENCY AUDITS
OF INDUSTRIAL SYSTEMS
OBJECTIVE
 Determine the specific opportunities to decrease
the energy consumption preserving the quality of
the produced goods and provided services;
 Propose energy efficiency improvement measures.

ENERGY EFFICIENCY AUDIT
• Using liquid or solid fuel
with rated power of
20 to 100 kW – at each three years;
• Using liquid or solid fuel
with rated power
over 100 kW – at each two years;
• Using liquid natural gas with rated
power of more than 100 kW – at
each four years.
Systems with rated
electricity power
higher than 12 kW
– at each four years
