This Order validates the Methodology for determining the baseline level of energy efficiency. It establishes the legal basis and assigns responsibility for implementation and oversight. The Methodology applies primarily to buildings owned or used by public authorities and local self-government bodies and aims to standardize how baseline consumption and energy savings are assessed across different types of energy and utilities.
The Methodology defines general principles and key terms, including the concept of a baseline energy efficiency level as a normalized measure of a building’s consumption of heat, electricity, gas, and water under standard operating and climatic conditions. It requires that calculations take into account factors such as indoor temperature regimes, building usage patterns, number of working days, and external climatic conditions. Baseline levels are determined using actual metering data covering three representative years selected from the last ten years, and they must be updated at least once every five years. Special provisions apply to newly constructed or renovated buildings, where baseline values may initially rely on energy certificates or audit data and be recalculated annually during an adjustment period.
The core of the Methodology provides detailed formulas and procedures for calculating baseline consumption for different resources—thermal energy, cold and hot water, electricity, and natural gas—based on metered data, normalized conditions, and correction coefficients reflecting external influences. It also establishes methods to calculate energy savings by comparing actual consumption with baseline levels, expressed both as percentages and absolute values. Additional provisions define how to calculate annual consumption for each resource and include standardized assumptions such as normative indoor temperatures for different building types. Overall, the document creates a unified, data-driven framework for monitoring energy efficiency and quantifying savings in public-sector buildings.
