Enabling Net-Zero
High-performance design and low-embodied-carbon strategies that move the needle on operational and lifecycle emissions.
eCube is a simulation-driven sustainability consultancy. Alongside architects, engineers and policy-makers we deliver high-performance, climate-adaptive, net-zero buildings — shaped by building physics, backed by evidence.
At eCube, sustainability isn't a feature — it's the blueprint. We fuse building physics, climate data and human comfort into designs that outperform code, outlast trends, and outpace carbon targets.
Enabling Net-Zero
High-performance design and low-embodied-carbon strategies that move the needle on operational and lifecycle emissions.
Comfort for all
Thermal comfort, enhanced indoor air quality, daylight-optimised interiors. Engineered around the occupants, not around the envelope.
Value that compounds
Customized, cost-effective solutions sized to your budget and energy goals. Savings you can model before the foundation is poured.
To create sustainable, future-ready designs that protect and comfort every occupant while minimizing climate impact — contributing to India's Panchamrit goal of Net-Zero by 2070.
Continuous, iterative simulation across pre-design, design and construction — so every building we touch delivers 100% thermal comfort and 60% less energy use.
From the first sketch to the last commissioning report — simulation, analysis and certification, integrated.
Whole-building energy models across pre-design, design and construction. We size HVAC, optimise envelopes and forecast savings before a single brick is laid.
Level I–III audits of existing buildings. We find wasted kilowatt-hours and turn them into retrofit ROI.
NZEB strategy, roadmap and verification — from low-carbon envelopes to on-site renewables.
Climate-based daylight modeling. Healthier interiors, lower electric-lighting loads, better views.
Airflow simulation for passive cooling, comfort and outdoor microclimate design.
End-to-end LEED, IGBC, GRIHA and EDGE support — documentation, modeling, submission and review.
Recognised by the US DOE, PLEA and IBPSA — we publish what we practise.
Solar PV sizing, feasibility and integration with building loads. Generation that matches demand.
We don't sell certifications — we deliver buildings that use less, feel better, and cost less to run. Every number here comes from simulation-validated project outcomes.
See how we'd approach your projectA sampling of buildings across India and the USA — simulated, certified and delivered in partnership with leading firms.
Certified green buildings consistently command higher rent, higher occupancy and lower operating costs. We make the paperwork painless.
The global benchmark. Platinum, Gold, Silver and Certified — we've navigated the path on all of them.
Tailored to Indian climates and codes. Ratings for new construction, existing buildings and interiors.
India's national rating. Integrated habitat thinking — site, water, energy, materials, operations.
Fast, cost-effective certification from the IFC — perfect for mass housing and commercial portfolios.
A compact team, deeply credentialed, built around one belief: buildings should perform.

Every decision is simulated before it's built. Every outcome is measured after.
Climate, site, program, budget and goals. We listen to architects and engineers, and translate intent into measurable targets.
Early-stage energy, daylight and CFD models. Hundreds of iterations — only the best ideas survive.
Envelope, HVAC, lighting and renewables tuned to the climate. Trade-offs quantified, not guessed.
LEED, IGBC, GRIHA or EDGE documentation — prepared, submitted, defended.
Commissioning and post-occupancy evaluation. The building performs because we designed it to.
Whether it's a campus, a tower, a school or a retrofit — if it has a climate and an occupant, we can make it perform.
