Cooling as a Service

Cut your chiller energy costs by 20–30% · Performance guaranteed · Greenergy manages everything

What problem are we solving?

40–60% of your electricity bill goes to cooling

Your chiller plant is likely the single biggest energy consumer in your building — running 24/7, often at far below peak efficiency.

After 10 years, maintenance costs accelerate

Aging compressors, leaking refrigerant, failing controls. Every year you delay replacement, you pay more — and risk an unexpected shutdown.

THB 5–30M to replace — capital you'd rather deploy elsewhere

A full chiller plant upgrade ties up capital for years. With CaaS, that budget stays in your business.

What is Cooling as a Service?

CaaS is simple: Greenergy invests in your cooling system. We design, install, and operate it. You pay a fixed monthly fee based on the cooling your building actually uses.

No capital outlay.
No maintenance headaches.
No performance risk.

If the system underperforms, that's our cost — not yours. Your energy performance is guaranteed by contract.

Hospitals & Healthcare

Cooling failure in a hospital isn't an inconvenience — it's a patient safety risk. Your HVAC runs 24/7, accounts for the majority of your electricity bill, and is under pressure from ESG compliance. CaaS means guaranteed uptime, 20–30% savings, and zero capital burden — so you can focus on patient care, not chiller maintenance.

Grade A/B Office Buildings

More than 60% of Grade A/B office buildings in Bangkok run chillers over 10 years old. That means rising electricity costs, falling tenant comfort, and a ticking clock to expensive replacement. CaaS lets you upgrade without CAPEX — start saving from month one and increase your building's value for tenants.
