Promotion of Eco-glass S and Eco-glass

FLAT GLASS MANUFACTURERS ASSOCIATION OF JAPAN

Outline

Eco-glass S and Eco-glass have higher heat shielding and thermal insulation performances than single-glazed glass and general insulating glass which are widely used for houses in Japan.
If we use them instead of single-glazed glass or general insulating glass, reduction effect of greenhouse gases emission will be expected by reducing air conditioning load of buildings.
From the viewpoint of environmental load in the product life cycle, Eco-glass S and Eco-glass are adopted in many new houses, today.
However, they have not be popularized in existing houses field in Japan yet.

Description

In April 2006, we registered a trademark for low-E insulated glass unit with a high energy-saving effect with the common name "Eco-Glass" and started activities to promote its dissemination.
Furthermore, in June 2019, we named “Eco-Glass S” for Eco-Glass with high performance, and we started activities to promote its usage.
According to our research in fiscal 2018, the penetration rate of eco-glass in new housing were 81.8% for detached houses and 25.9% for apartment houses in Japan. It is however assumed that the spread to existing houses is still small.
We estimate that CO2 emission reduction potentials to be approximately 17 million tons per year by replacing all domestic windows with eco-glass.
In Challenge Zero, we aim to popularize eco-glass to existing houses field in Japan. (We will not set the quantitative targets, because quantitative evaluations should be difficult.)
It is essential to establish the legal systems such as government grant, because actions of company level and/or industry sector have limitations.
And strong lobbying activities by the whole economic world to the national and local governments should be necessary.
