Karl Rabe on Rethinking Data Centers Starts Before the Power Is Switched On


Listen Later

🎯 In this episode: Karl Rabe, Founder and Managing Director of WoodenDataCenter and Co-Lead of the Modular Data Center Group at the Open Compute Project Foundation, explains why data center sustainability must begin long before the servers are switched on.

The conversation explores how, as renewable electricity reduces operational emissions, the majority of a data center’s footprint shifts to embedded emissions in construction materials, equipment, and supply chains. Rabe discusses why materials like cross-laminated timber (CLT) can significantly cut upfront carbon while improving speed and cost competitiveness through modular construction. He shares insights from hyperscale projects, noting that construction materials can account for 40-60% of total emissions, and up to 99% once power is fully decarbonized. The episode also covers modular infrastructure, open standards through the Open Compute Project, regional energy considerations, and how energy-integrated data centers can support grid stability with storage, flexible loads, and heat recovery. Ultimately, the discussion highlights why early design decisions, material choices, and system integration are becoming central to both climate performance and commercial success in digital infrastructure.
