Legal and Regulatory Framework for Energy Efficiency in Bulgaria
The layered legal picture
Bulgarian energy efficiency law is a stack: EU directives (notably the Energy Efficiency Directive and the Energy Performance of Buildings Directive) are transposed into national statutes, chiefly the Energy Efficiency Act (Закон за енергийната ефективност, ЗЕЕ) and the Energy from Renewable Sources Act, and then into secondary legislation - ordinances (наредби) and regulations issued by the Council of Ministers and the Minister of Energy. Candidates must know that ordinances set the methodology (audit scope, certificate content, minimum performance requirements), while the Act sets obligations and institutions.
Institutions and obligations
Key bodies: the Sustainable Energy Development Agency (SEDA/AUER) - maintains the register of certified energy auditors and registered audit reports and exercises quality control; the Ministry of Regional Development and Public Works - building energy performance rules; municipalities - their own EE programmes and obligations for public buildings. Obligated parties include large enterprises (subject to mandatory energy audits at intervals), public building owners above floor-area thresholds, and energy suppliers under the energy-efficiency obligation scheme. Traps: confusing who registers a report (SEDA) with who commissions it (the owner); mixing the audit validity period with the certificate validity period; assuming every building needs a certificate (only those sold, rented, or newly built, plus public buildings over the threshold displayed publicly).
Worked example
A 2,400 m² municipal office building is being sold. Rule of thumb: the seller must make a valid energy performance certificate available to the buyer before contract, but a full energy audit is a separate obligation triggered by enterprise size or public-building thresholds - a certificate alone does not substitute for an audit. If the certificate is older than its validity window, a new one is required.
Exam traps
Watch for questions that swap the roles of SEDA and the municipality, or that treat EU directives as directly binding on a private owner (they are not - national transposition is).
