Energy Conservation Building Code (ECBC) and Eco-Niwas Samhita (ENS and Energy Conservation Sustainable Building Code (ECSBC) compliance assessments evaluate the energy performance of buildings to ensure they meet prescribed national energy efficiency standards. Our service provides detailed building energy modelling and compliance analysis to verify whether the proposed design meets the mandatory requirements of the applicable code.
The procedure for compliance is through a Third-Party Assessor (TPA) during various stages of the project ECBC is mandatory in Maharashtra from 29th May 2025 for commercial and office building having BUA 1000sqm and connected load 100kW or contract demand 120KVA
Specific Services
ECBC Code Compliance
Energy Conservation Building Code (ECBC) compliance focuses on evaluating the energy performance of commercial buildings. Through detailed energy modelling, the assessment verifies whether the building envelope, lighting systems, and HVAC equipment meet the prescribed energy efficiency standards set by the Bureau of Energy Efficiency (BEE).

ECSBC Code Compliance
Energy Conservation Sustainable Building Code (ECSBC) extends beyond basic energy efficiency by incorporating sustainability parameters such as renewable energy integration, water efficiency, and passive design strategies. The analysis ensures that the building achieves higher performance benchmarks aligned with sustainable development goals.

ENS (Eco-Niwas Samhita) Compliance
Eco-Niwas Samhita (ENS) focuses on improving the thermal performance of residential buildings through optimized building envelope design. The assessment evaluates parameters such as wall and roof insulation, window performance, and shading strategies to ensure improved thermal comfort and reduced residential energy demand.

Is RDT an official Third-Party Assessor (TPA) for ECBC code compliance?
In Maharashtra, the TPA procedure is still in the process, but with our expertise we can provide you support for the detail compliance.
Which buildings are required to comply with ECBC?
ECBC applies to commercial buildings, including offices and other non-residential facilities, that have a connected load of 100 kW or greater or a contract demand of 120 kVA or more.
At what stage should ECBC/ECSBC compliance analysis be conducted?
ECBC/ECSBC compliance is required across different stages of the building lifecycle, ensuring that the building maintains energy efficiency standards throughout its development and operation. The stages are:
- Design stage- Before starting the construction
- Construction stage- After construction, before OC and operational stage, ensuring that the building maintains energy efficiency standards throughout its development and operation.
