Bulgarian Energy Efficiency Consultant Exam study guide
Bulgarian Energy Efficiency Consultant Exam · Work through your exam, one topic at a time.
The Bulgarian Energy Efficiency Consultant certification is a professional credential for specialists who assess, certify, and improve the energy performance of buildings and installations in Bulgaria. It is aimed at energy auditors, building services engineers, architects, and consultants who already work with thermal performance, HVAC systems, and renovation projects, and who want their competence recognised in a regulated market. The Bulgarian Energy Efficiency Consultant Exam study guide has 9 sections and about 2,735 words.
01Legal and Regulatory Framework for Energy Efficiency in Bulgaria
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 .
371 words, about 2 min02Energy Auditing Methodology and Standards
A compliant audit follows a defined sequence: data collection (bills, drawings, nameplate data, operating schedules), walk-through and inventory , measurement , energy balance and disaggregation , identification of measures , and reporting . Bulgarian practice aligns with the EN 16247 series (general requirements, buildings, processes, transport) and, for enterprises, with the requirements that audits be proportionate, based on measured/verifiable data, and traceable.
330 words, about 2 min03Building Envelope and Thermal Performance
The envelope controls transmission and infiltration losses. Know U-value (W/m²K) as the inverse of thermal resistance; the assembly R is the sum of layer resistances plus surface films (Rsi, Rse).
304 words, about 2 min04HVAC, Lighting, and Building Energy Systems
Understand the seasonal efficiency metrics: for heat pumps SCOP/SPF; for boilers seasonal efficiency; for chillers SEER. Key concepts: part-load behaviour, distribution losses , hydronic balancing, pump and fan affinity laws (flow ∝ speed, power ∝ speed³), and heat recovery ventilation .
277 words, about 1 min05Energy Performance Certificates and Building Certification
An energy performance certificate states the building's calculated or measured energy performance, expressed as a primary energy indicator and a class (A–G in Bulgarian practice), with recommendations for improvement. It is issued by a certified auditor/assessor and registered.
319 words, about 2 min06Energy Efficiency Measures and Economic Analysis
Economic analysis turns audit findings into decisions. Know simple payback (investment / annual savings), life-cycle cost (LCC) , net present value (NPV) , internal rate of return (IRR) , and levelized cost of conserved energy .
279 words, about 1 min07Renewable Energy Integration and Nearly Zero-Energy Buildings
A nearly zero-energy building has very high energy performance, with the low remaining demand covered to a significant extent by renewable energy , including on-site or nearby sources. Bulgarian requirements apply to new public buildings first, then all new buildings, with defined thresholds.
296 words, about 1 min08Measurement, Verification, and Energy Monitoring
Savings are avoided energy use , not a meter reading - they must be verified . The recognized framework is the IPMVP (International Performance Measurement and Verification Protocol), with options: A (retrofit isolation, key parameters measured), B (retrofit isolation, all parameters measured), C (whole facility), and D (calibrated simulation).
251 words, about 1 min09Professional Ethics, Reporting, and Consultant Practice
An energy consultant's value rests on independence, competence, transparency, and confidentiality . Conflicts of interest must be disclosed - for example, recommending equipment from a supplier you represent, or auditing a building you designed.
