ECBC 2017 Compliance Checklist
ECBC 2017 (BEE) applies to commercial buildings or building complexes with a connected load of 100 kW / contract demand of 120 kVA or above — verify your State's notified version, since some States have amended the threshold or the compliance date. Decisions on envelope and orientation are architectural, so engage with it at schematic stage.

Tiers & compliance route
- Target a tier: ECBC, ECBC+ or SuperECBC (increasing energy performance).
- Choose a compliance route: Prescriptive, or the Whole-Building Performance (WBP) simulation route.
- Account for the building's climate zone (India's five zones: Hot-Dry, Warm-Humid, Composite, Temperate, Cold).
Building envelope
- Wall and roof assembly U-values / insulation within ECBC limits for the climate zone.
- Window-to-wall ratio, glazing SHGC and U-value, and shading addressed for orientation.
- Cool/high-reflectance roof where applicable.
HVAC & lighting
- HVAC equipment efficiency (COP / IPLV) meets ECBC minimums; controls and economisers where required.
- Lighting Power Density (LPD) within ECBC limits, with daylight and occupancy controls.
Mandatory provisions
- Mandatory renewable-energy provision (e.g. solar) as required by ECBC for the building.
- Metering / sub-metering of major energy end-uses.
Verify — ECBC applicability thresholds, tier requirements and numeric limits depend on the State-notified version and the climate zone. Confirm against ECBC 2017 (and your State ECBC) with an energy/MEP consultant.
Frequently asked
What is ECBC 2017?
ECBC 2017 is the Energy Conservation Building Code published by the Bureau of Energy Efficiency — India's minimum energy-performance standard for commercial buildings, covering the envelope, HVAC, lighting, electrical distribution and renewable-energy provisions, with three performance tiers: ECBC, ECBC+ and SuperECBC.
Which buildings does ECBC 2017 apply to?
Commercial buildings or complexes with a connected load of 100 kW or contract demand of 120 kVA and above — as notified by each State. Enforcement runs through State notification and the local building-approval process, so check whether your State has adopted or amended the code and thresholds.
Is ECBC 2017 mandatory?
The code becomes enforceable in a State once that State notifies it (some with amendments). Where notified, compliance is checked at building-permit stage for in-scope buildings; where not yet notified, it remains the reference standard that green-rating systems and many institutional clients specify anyway.
What are the ECBC, ECBC+ and SuperECBC tiers?
Three ascending performance levels of the same code. ECBC is the baseline mandatory tier; ECBC+ and SuperECBC tighten envelope, equipment-efficiency and lighting-power requirements for progressively lower energy consumption — useful targets when a client wants performance beyond minimum compliance.
How do you show ECBC compliance?
Two routes: the prescriptive route, meeting each component requirement (U-values, SHGC, equipment COP/IPLV, LPD) for your climate zone — or the Whole-Building Performance route, simulating the design against a reference building. Prescriptive is simpler; simulation buys design flexibility on tricky envelopes.
Want this checked against your drawings?
We'll review your scheme against the governing code and own the statutory approvals — so compliance is designed in, not retrofitted. The other checklists, clearance guides and specification libraries are on the architects' hub.
