ABOUT THE EXAMINATION
What the 26th NCE Energy Auditor (Building) paper covers
The National Certification Examination (NCE) is held under the Energy Conservation Act, 2001. For the 26th NCE it is conducted by the Dr. Ambedkar Institute of Productivity (AIP), the training arm of the National Productivity Council (NPC) in Chennai — the designated National Certifying Agency — on behalf of the Bureau of Energy Efficiency (BEE).
The examination certifies Energy Managers, Energy Auditors and Energy Auditors (Building). This companion is built for the Energy Auditor (Building) track, which tests the two 2024 building frameworks — ECSBC 2024 for commercial and office buildings and ENS 2024 for residential buildings — drawn from BEE National Certification Guidebooks Book 5 and Book 6.
A candidate must score at least 50% in each paper to qualify. Your admit card, exam schedule and results are published on the official portal, nceexam.in. Always confirm dates and paper structure there before your exam.

11. Indoor Environmental Quality (IEQ)
Plus a complete 200-mark model question paper with worked solutions.
QUICK-REFERENCE STANDARDS
Codes worth committing to memory
Several answers turn on a threshold printed in the code rather than on the underlying physics. These are the standards the guidebooks lean on — the full matrix is inside the companion.
Standard | Subject area | Why it matters |
IS 10500 : 2012 | Drinking water quality | Potable parameters; TDS and coliform limits for drinking and food preparation |
IS 16590 | Chiller rating | Full-load and part-load IPLV / COP efficiency benchmarks |
IS/ISO 16890 | Air filters | HVAC particulate classification — ePM1, ePM2.5, ePM10 |
IS 17515 | Vertical transport | Lift energy-efficiency classes; Class A required for the Super tier |
IS 3646 (Part 1) | Interior illumination | Recommended illuminance and lighting quality by task and space |
ISO 15099 | Glazing performance | U-factor, SHGC and VLT for frame and centre-of-glass |
EN ISO 7730 | Thermal comfort | PMV and PPD comfort indices and comfort boundary curves |
ASHRAE 140 | Energy simulation | Standard test for validating whole-building simulation engines |
ASHRAE 55 | Thermal environment | Adaptive comfort model and operative temperature |
IEEE 519 / IEC 61000 | Power quality | Harmonic voltage and current limits at the point of common coupling |
HOW TO PREPARE
Four ways to get the most from it
• Lock the objective bank first. Work Section A across all eleven chapters early; the paper rewards knowing definitions, classes and code numbers cold.
• Do the numericals by hand. Recurring calculations — U = 1/R with surface films, cooling-tower range/approach, evaporation loss, transformer copper loss ∝ load², 1 TR = 3.517 kW — should feel automatic before exam day.
• Keep the threshold tables close. Envelope U-factors, SHGC, lighting power density and chiller COP limits come straight from ECSBC 2024 / ENS 2024. Where an answer hinges on the code value, memorise the value.
• Sit the model paper timed. Attempt the full 200-mark paper once under three-hour conditions, then mark yourself against the worked solutions to find where time and accuracy slip.

PLEASE NOTE
A study aid, not a substitute for the code
• This companion is compiled by SEA Energy from the official BEE National Certification Guidebooks (Book 5 & Book 6). It is an independent preparation aid and is not published or endorsed by BEE or NPC.
• It does not replace the official guidebooks, the prospectus, or the ECSBC 2024 and ENS 2024 code text. Always cross-check thresholds and clauses against the current code before relying on them.
• Every numerical solution was recomputed from first principles and every objective answer checked against building-science and code practice before publication; a verification and corrections register is included inside.
• Free to download, use and share for exam preparation. If it helps you, pass it on to a fellow candidate.
