Environmental Technology Verification(ETV) Program
Verification Test Result
W hat is the E n viro n m en ta l Te ch n o lo gy Ve rifica tio n (E T V ) p ro gra m ?
There are advanced environmental technologies that are ready for commercial application and are believed to be useful, but neverthelessare not yet being widely used simply because of the absence of an objective assessment of their environmental conservation effects, etc.
The ETV program aims to establish the method and system to verify such environmental technologies and facilitate their spread,the preservation of the environment and the development of the environmental industry, with the third party implementing objective
verification of environmental preservation effects, etc.

Lowering the set temperature of air conditioner

ZEROCOAT is a siloxane compound coating film and chemically stable. It forms a hard coat layer
with high density and hardness, providing hyaline coating that is highly weather resistant andhard to deteriorate.
ZEROCOAT
General coatingby only 1℃ can reduce 10% of power consumption.
ZEROCOAT applied to window glass can cut over 90%of near-infrared rays which are the heat source.
Once the window glass is coated, the temperaturenear it will fall by 5 to 10℃, resulting in

Floor is warmed and re-emits heat, which raises
room temperature and increases the need for airconditioning.
Sunlight turns carpet, furniture and otherarticles into brown and deteriorates them. It
also causes bad effects on skins like spots andfreckles.

Since floor is warmed less and emits less heat,room temperature will not rise easily and the needfor air conditioning will fall.
Coated window glass will prevent carpet, furnitureand other articles from turning to brown anddeteriorating. It also protects our body from badeffects of sunlight such as spots and freckles.
