The Indian real estate industry has projections of 230 million housing units in urban areas by 2047, accommodating 51% of India's population. With increasing aspirations of building occupants and a warmer climate, air conditioning...
This paper evaluates the financial viability of investing in either wall insulation or energy-efficient air conditioning systems in Indian residential buildings. India's rapid urbanization is expected to create demand for approximately...
In our study we present EUI benchmarks for NZEBs for six building types across residential and non-residential typologies and for India's five climate zones. This approach is similar to the simulation-based benchmarks used by the B3...
The building sector in India contributes to about one-fifth of the country's total CO2 emissions. At COP26, India has committed to achieving net-zero by 2070 (RMI India, 2021). Net-Zero Energy Buildings (NZEBs) can accelerate the pace...
India's building construction industry is witnessing remarkable growth trends, particularly office spaces. Estimates suggest 80% of the buildings that will exist in the year 2050 is yet to be constructed. Building industry is...
India's building sector contributes to 39% of greenhouse gas emissions. Communities have begun to face climate change through heatwaves, droughts, floods, and cloud bursts. Our buildings need to become net-zero, but the building sector...
Two pillars of eCube's evidence-based design practice - an industry-leading daylight simulation platform and the world's largest net-zero design competition.
eCube is the authorised distributor of LightStanza in India - a cloud-based daylight simulation and analysis platform used globally by architects and engineers to optimise natural light, glare, and artificial lighting in buildings. We offer access, training and project support across India.

Deep-dive critiques of building energy performance and sustainable design in India - frank, research-backed and unfiltered.
A no-holds-barred critique of how energy codes, building practices and sustainability certifications often miss the mark in the Indian context.
An unfiltered look at what it really takes to deliver a climate-responsive home in India - the design trade-offs, the on-site compromises, and the gap between performance goals on paper and performance in practice.
