The Industry

THE CURRENT HONG KONGCOOLING INDUSTRY

01

Inefficient Legacy Systems

Cooling is the single largest electricity load while traditional Air Conditioning is costly to maintain, energy-intensive, and a major contributor to global carbon emissions.

02

Urban Energy Burden

In high-density cities like Hong Kong, commercial and industrial building operations account for 70% of total electricity consumption in which around 30% comes from air conditioning. (EMSD Hong Kong Energy End-Use Data 2025)

03

The Warming Vicious Cycle

Rising global temperatures increase cooling demand, which accelerates global warming through high energy use, not to mention the rising electricity demand from the R&D of AI and other technology innovation

Electricity Consumption by End-use

Electricity consumption by end-use in 2013 and 2023 Two concentric rings compare end-use categories. The thicker outer ring is 2023 and the thinner inner ring is 2013. 2023 Air Conditioning: 30% 2023 Lighting: 10% 2023 Refrigeration: 4% 2023 Industrial Process/Equipment: 3% 2023 Cooking: 9% 2023 Hot Water: 4% 2023 Office Equipment: 6% 2023 Vertical Transport: 5% 2023 Others: 29% 2013 Air Conditioning: 27% 2013 Lighting: 11% 2013 Refrigeration: 4% 2013 Industrial Process/Equipment: 6% 2013 Cooking: 8% 2013 Hot Water: 3% 2013 Office Equipment: 7% 2013 Others: 33% AIR CONDITIONING 27% → 30% +3%

Our Solution

OUR SOLUTION - DECOUPLEDRADIANT COOLING (DRC)

01

The Concept

Cooling spaces through a pinpoint radiative heat exchange rather than circulating cold air. A fundamental shift from cooling air to cooling people and surfaces directly

02

The Innovation

Integration of advanced materials science with DRC panels to achieve high IR transmittance and structural durability.

03

The Vision

“Turn cooling into a more elegant form” — a pinpoint temperature control system that works like a light switch.

Unmatched Energy Efficiency

Cut energy use by 25%–40% with radiant-focused panels that reduce fan power and circulation needs.

Health & Pathogen Safety

No air circulation means minimal airborne cross-contamination—ideal for hospitals and shared offices.

Precise Thermal Comfort

Experience quiet, draft-free cooling with uniform temperature distribution which creates a more personalized cooling experience.

DRC vs AIR-BASED SYSTEMS

Radiant Cooling and Air-based Systems

Radiant Cooling and Air-based Systems Comparison
Attribute Radiant Cooling Air-based systems (e.g., VRF, AHU, FCU)
Cooling Principle Cools surfaces (ceilings, floors, panels) so occupants dispose heat by radiation. Cools air directly and distributes conditioned air to spaces.
Sensible vs Latent Load Handling Excellent for sensible loads; poor at removing moisture. Handles both sensible and latent loads via supply air and dehumidification.
Cooling Capacity Density Moderate; lower peak capacity per area. High peak capacity; can deliver large sensible + latent loads quickly.
Energy Performance High part-load efficiency. Efficient with modern VRF and high-efficiency AHUs; higher fan energy for air movement.
Indoor Air Quality Requires separate DOAS ventilation for IAQ and moisture control. Integrated ventilation and filtration options; easier to control IAQ centrally.
Space and Architectural Impact Minimal ductwork; needs ceiling/floor integration and structural coordination. Requires space for ducts, plant rooms, ceiling voids; more intrusive in retrofits.
Installation Complexity Moderate (integration with structure, piping routing). Moderate; easier for modular installs (VRF) but complex for central AHU + ductwork.
Maintenance Access to panels/piping needed; risk of hidden leaks. Routine maintenance; easier fault isolation.
Condensation Risk High; needs robust humidity control. Lower if ventilation and dehumidification sized correctly; condensation mainly at coils.

How it works

WHY DRC IS REVOLUTIONARY- Low-carbon Thermal Environment Creation

Read the system in three moves: remove sensible heat at the panel, manage fresh-air moisture separately, then tune each control loop.

How it works
R
01 / DRC · Sensible = heat

Panels absorb sensible heat

DRC systems aims to deal with sensible load: cooling water temperature 5–15°C; indoor air temperature 26.0 ± 1°C; operating temperature 24 ± 0.5°C.

A
02 / Fresh air · Latent = moisture

Fresh air manages latent load

Fresh air ventilation system deal with latent load: relative humidity 50–60%.

C
03 / Control

Controls tune comfort

Thermostat and humidity controller work independently.

Technology

THE TECHNOLOGICAL BREAKTHROUGH

“Radiant cooling is a space-cooling approach that removes heat by thermal radiation and conduction from room surfaces (floors, ceilings, or walls) rather than primarily by blowing cold air. Systems lower surface temperatures so occupants and objects shed heat to those surfaces, reducing perceived temperature without needing as much cold supply air.”
