Thermal Comfort, Reimagined for Real Buildings

Thermal Comfort Technology

Seisou’s SLOW system  replaces refrigerant heavy,  energy guzzling air conditioning with a smarter, water-based thermal comfort system, cutting energy by ~30%, eliminating dry air, and delivering uniform comfort across your entire space. The intelligent alternative to AC built for Indian buildings and commercial spaces.

~30%

Lower cooling energy

Zero cold spots

Uniform cooling leading to superior comfort

Installation Time

Hours

Commercial buildings spend 60–70% of their energy bill on cooling alone

As temperatures rise across India, cooling costs go up - while thermal comfort goes down. Traditional HVAC and AC systems were never designed for modern buildings.

Uneven Hot & Cold Spots

Forced air creates temperature gradients across large spaces — some desks are freezing, others are sweltering. Employees spend more time adjusting thermostats than working.

Dry Air & Poor Air Quality

Conventional AC strips moisture from the air, leading to dry skin, irritated eyes, and increased spread of airborne pathogens. Occupants’ health pays the price.

High Energy Bills

Cooling is the single largest electricity cost in most Indian commercial buildings. Aging HVAC systems only make this worse — consuming more energy every year for less comfort.

Locked into Outdated Systems

Traditional HVAC requires extensive ductwork, high maintenance, and long replacement cycles. Most buildings are stuck with systems that were designed decades ago.

"Buildings which are good for the planet are going to be closer to nature. They're going to be buildings which are not sealed boxes recirculating refrigerated air, which is not the healthiest."
-Lord Norman Foster, Architect 

SLOW

SLOW is a sustainable cooling technology built around a simple truth — water moves heat far better than air. Our ceiling-mounted thermal comfort panels absorb heat directly from the room and remove it efficiently through circulating water, with no forced air, no noise, and no cold drafts. This is the next generation of thermal comfort solution for commercial spaces.



Sleek, nature inspired ceiling panels

Designed to meld seamlessly into your spaces. No bulky units, no exposed ductwork - just clean, architectural surfaces that deliver uniform thermal comfort.

~30% lower cooling energy

Water-based heat transfer is dramatically more efficient than air. Reduce HVAC energy consumption without reducing comfort.

No harsh drafts, no freezing zones, and no noise.

Just fresh air and flawless, invisible thermal comfort from the moment you walk in.

Installs in hours, not weeks

Retrofit-friendly by design. SLOW is designed to work in existing buildings with minimal disruption to your operations.

"A modern skyscraper is a machine for converting solar energy into heat, which must then be pumped out by another machine."
-Amory Lovins, Physicist and former Chairman, Rocky Mountain Institute 

Why It Matters

~30% Average reduction in cooling energy when switching to SLOW

India’s commercial buildings are under pressure – rising temperatures, rising energy costs, and rising expectations around sustainability. Seisou delivers a sustainable solution that actually works – not just on paper, but in real buildings, for real people.

Better Thermal Comfort

Uniform temperatures across every corner of your space. No more thermostat wars. No more complaints from employees about the AC. SLOW panels - minimal profile, maximum comfort. Entire room reaches uniform comfort Without forced air, temperatures equalise naturally. No cold spots. No hot zones.

Lower Energy Bills & Reduced Maintenance

~30% reduction in cooling energy means significant savings on your electricity bill every single month - compounding year after year. Fewer moving parts, no filters to change, no ducts to clean. SLOW is designed for minimal maintenance and a longer system life.

Healthier Air Quality & Quiet Workspaces

No forced air means no circulating allergens, or pathogens. Humidity stays natural. Your team breathes better air, all day long. No fans, no hum, no disruption. SLOW operates in near silence, letting your team focus on their work, not the noise of the building.

Green Building Compliance

Supports LEED, GRIHA, and ESG sustainability goals. Seisou is the eco-friendly cooling system built for India's green building future.

Who It's For

Built for every commercial space.

Whether you’re managing a growing startup office or a Grade A commercial portfolio, SLOW  is designed to retrofit into your existing building with minimal disruption.

Fast installation, immediate comfort improvement, and measurable energy savings from day one. The smart alternative to AC for growing businesses.

Retrofit-friendly – old buildings with aging HVAC, low false ceilings, or limited ductwork options. SLOW is designed for exactly these constraints – bringing modern thermal comfort to existing spaces.
