What’s inside this ebook

Everything a team needs to design an AI data center that clears its power and water approvals: the physics, the water math, the carbon accounting, and a six-decision playbook, worked through in numbers.

How to read PUE, WUE, and PCE, and when liquid cooling becomes essential for high-density AI racks, so cooling is sized right from the first design.

The water math that sets a facility’s lifetime draw, and why cooling architecture is a site-selection decision in India’s water-stressed regions.

Where a building’s embodied carbon is really locked in, and the structural and material choices that lower it before power-on.

How to turn waste heat into a revenue and community asset, with the free-cooling and renewable-energy moves suited to each Indian climate zone.

The six-decision klimArt framework that gets power and water allocation approved and keeps a data center efficient for its whole life.

Executive summary

Sustainable architecture is now what gets an AI data center its power and water allocation approved. India is building close to a decade of AI infrastructure in about thirty-six months, with more than $120 billion already committed and capacity on course to grow roughly tenfold. The facilities that move first are the ones where cooling, water, and carbon are designed into the building at concept stage, while the largest savings in energy, water, and cost are still on the table.

This field guide works those numbers in full. It covers the physics of heat, from PUE and WUE to the point where liquid cooling becomes essential as close to three-quarters of AI servers worldwide move to it; the water question, where more than half of India’s data center regions already sit under water stress; and the embodied carbon locked in before power-on, where concrete alone can account for up to 80 percent of a facility’s material footprint. Every decision comes with the market, climate, and engineering data behind it.

It closes with the klimArt framework: six decisions, from the site and water audit to the certification pathway, that belong in the first design sketch. Resolved early, they let a facility run at a lower PUE, cut its water draw, earn its GRIHA or LEED rating, and secure the approvals that keep a project on schedule. It is the same climate-responsive discipline klimArt has brought to institutional and government projects across India since 2001.
