Veles Forge 1.1 • Special Report
The global demand for cooling is projected to triple by 2050. This report examines the technologies, economics, and emissions pathways that will define humanity's ability to stay cool on a warming planet.
The cooling technology landscape spans conventional vapor compression, advanced heat pumps, passive designs, and emerging solid-state systems. Each plays a distinct role in the transition.
Variable-speed compressors that modulate output to match load. 30–50% more efficient than fixed-speed units. Reversible for heating, replacing fossil fuel systems.
Centralized chilled water production distributed via insulated pipes. Achieves economies of scale and can integrate free cooling from lakes, rivers, or seawater.
Uses solar heat to drive absorption or adsorption chillers. Aligns supply with demand — peak cooling coincides with peak solar irradiation. Zero-electricity operation possible.
Circulates cooled water through ceiling or floor panels. Provides thermal comfort via radiant heat exchange rather than air convection. Ideal for commercial buildings.
Magnetocaloric, electrocaloric, and elastocaloric materials that heat/cool under applied fields. No refrigerants, no compressors. Potentially 20–30% efficiency gain over vapor compression.
Building orientation, shading, natural ventilation, cool roofs, and green façades. Reduces or eliminates mechanical cooling demand before it arises. The most cost-effective intervention.

|---|---|---|---|---|---|
| Conventional Split AC | 9 | 13–16 | 350–500 | 12–15 | Lowest upfront cost |
| Inverter AC | 9 | 18–24 | 500–750 | 12–18 | 30%+ efficiency gain |
| Air-Source Heat Pump | 9 | 18–28 | 800–1,400 | 15–20 | Heating & cooling |
| Ground-Source Heat Pump | 9 | 25–35 | 2,000–4,000 | 25–50 | Highest efficiency |
| District Cooling | 9 | 18–26 | 1,200–2,500 | 30–50 | Scale economies |
| Solar Absorption Chiller | 8 | 10–16 | 1,800–3,500 | 20–25 | Zero-electricity operation |
| Radiant Cooling | 8 | 20–28 | 1,000–2,000 | 30–50 | Comfort quality |
| Magnetocaloric (Solid-State) | 5 | 26–35* | TBD | 20+* | No refrigerants |
| Passive Design Measures | 9 | N/A | 50–300 | 30–100 | Eliminates demand |
Cooling is no longer a luxury good — it is a fundamental determinant of human welfare and economic productivity in a warming world. The policy challenge is threefold:
1. Efficiency Standards. Minimum Energy Performance Standards (MEPS) could halve the energy intensity of new AC units by 2035. The Kigali Amendment to the Montreal Protocol provides a regulatory framework for HFC phasedown that must be accelerated.
2. Access Equity. Over 2.8 billion people live in hot climates with cooling access below 10%. The intersection of cooling poverty and extreme heat is a humanitarian crisis — one that market forces alone will not solve.
3. Grid Integration. Cooling drives peak electricity demand in most warm-climate grids. Demand-response programs, thermal storage, and building envelope improvements can flatten the duck curve and reduce the need for peaker plants.
