How CryoPaint Cuts Cooling Energy Use: The Practical Numbers
There is a lot of marketing in this category about "eco-friendly" and "sustainable" cooling. Most of it is slogans. Below are the actual numbers a building owner or fleet operator should care about: surface temperature, HVAC load reduction, and dollar payback. No moralizing, just math.
What CryoPaint actually does to a surface
Under good conditions (clear sky, low humidity, still air with sustained wind under 5 mph, flat sky-facing surface, low insulation underneath), CryoPaint drops surface temperature by up to 15°F below the air temperature around it. Sustained wind above that threshold cuts into the delta because convection pulls the surface back toward air temperature. The two physics levers are:
- 94% solar reflectance, which prevents most of the sunlight from being absorbed in the first place.
- 90% 8–13 µm emissivity, meaning in the wavelengths that bypass the atmosphere, it radiates its own heat to space at 90% of the maximum rate possible.
On a flat roof in Phoenix on a July afternoon, a dark or aged-membrane roof routinely sits at 140°F to 170°F. A CryoPainted equivalent in the same conditions sits near or below 100°F. That is a 40°F to 70°F surface temperature reduction at peak.
What that surface temperature reduction does to HVAC
The HVAC system on a building sees the roof as a heat source any time the roof surface is hotter than the indoor setpoint. Heat conducts through the roof deck, through any insulation present, and into the conditioned space. The HVAC then has to remove that heat.
When the roof surface drops from 150°F to 95°F, the temperature gradient driving heat conduction into the building drops dramatically. For an uninsulated or lightly insulated roof (metal, single-ply membrane, asphalt rolled roofing), the reduction in conducted heat load translates almost directly into reduced HVAC runtime.
The magnitude depends on:
- How much insulation is between the roof surface and the conditioned space (more insulation means a smaller benefit from CryoPaint, because the insulation is already partly doing the job).
- How long the building is occupied during peak heat hours (longer occupancy hours equals more savings).
- The local electricity rate structure, particularly whether the utility uses time-of-use or demand charges (peak-shaving in the summer afternoons is where the dollars are).
- The size and condition of the existing HVAC system (an oversized or old unit sees a smaller relative improvement).
We routinely see retrofit candidates with 15% to 30% HVAC peak-load reduction projections, depending on those variables. The honest answer is to run the math on your specific building, not to take a generic percentage.
A worked example
We modeled CryoPaint against R-30 polyiso insulation for an 87,000 sq ft data center in Phoenix (ASHRAE climate zone 2B, cooling-dominated, year-round high cooling load).
| Approach | Installed cost | Annual energy savings | Simple payback |
|---|---|---|---|
| R-30 polyiso retrofit (above-deck) | ~$5 to $7 per sq ft | Significant cooling savings, small heating savings | Roughly 21 years |
| CryoPaint applied at 1 oz/ft² | ~$1.95 per sq ft material, plus labor | Comparable cooling-side savings | Roughly 2.3 years |
The polyiso wins on year-round R-value and on cold-climate performance. CryoPaint wins on cooling-only retrofit in a hot climate, by a factor of roughly 9 to 1 on payback. Phoenix, Tucson, Las Vegas, El Paso, and similar cooling-dominated markets are where the math works hardest.
Cabin temperature and equipment longevity
For applications other than building HVAC, the value chain works the same way.
- Fleet vehicles, RVs, and school buses: A cooler cabin after sitting in the sun reduces the initial cabin pre-conditioning energy when the engine or HVAC starts. For EVs specifically, lower cabin solar gain reduces A/C load while driving, which recaptures a portion of the hot-weather range loss documented by AAA (around 8.5% loss at 95°F versus 75°F in their May 2026 testing).
- Shipping containers and outdoor equipment enclosures: Interior temperature follows roof temperature with a lag. Lower roof temperature means less rubber, gasket, and electronic thermal stress inside. The replacement cycles on temperature-stressed components extend.
- Dairy and livestock buildings: Heat stress in dairy cattle reduces milk production. Reducing roof surface temperature reduces the radiant heat load on the animals below, which can meaningfully improve milk yield through the hot months.
What CryoPaint does not save
A few things to be clear about so the math stays honest:
- CryoPaint does not reduce electricity used for lighting, plug loads, motors, refrigeration, or anything other than cooling.
- It does not heat in winter. In a cold climate or a building with significant winter heating load, the savings on cooling do not offset additional winter heating cost (which is actually small, since reflective coatings have only modest winter penalty in most US climates, but it is not zero).
- It does not replace insulation. Insulation reduces conduction. CryoPaint reduces surface temperature. Both are useful, with different strengths.
- It does not produce energy. It reduces the energy required for cooling, which is a different and more honest claim.
When the payback is fastest
The fastest paybacks are on:
- Cooling-dominated climates (ASHRAE zones 1, 2, and the hotter parts of 3).
- Low-insulation, sky-facing roofs (metal, single-ply, rolled asphalt).
- Buildings with high summer occupancy.
- Utility rate structures with significant time-of-use or demand charges.
- Owners who hold the property long enough to capture multiple cooling seasons of savings.
The slowest paybacks are on:
- Cold or mixed climates.
- Heavily insulated commercial roofs.
- Vacant or seasonally occupied buildings.
- Properties already sized for the peak load with no operating cost pain.
Bottom line
CryoPaint is an operating-cost tool. It reduces the cooling energy your building or vehicle needs, and the dollar value of that reduction depends on your climate, your building, your occupancy, and your utility rate. In hot, dry climates with low-insulation roofs, the payback is fast (the data-center model above shows roughly 2.3 years). In other markets, it is slower or smaller.
