Using Insulating Green Building Materials is a One-Time Solution for Building Energy Efficiency

Taiwan is grappling with increasingly intense heat, with temperatures already soaring above 35 degrees Celsius even before the official start of summer. This extreme weather forces widespread use of air conditioning in commercial spaces, offices, and homes, placing significant stress on the national power supply. The heat emitted from buildings also exacerbates the outdoor temperature, making it difficult to spend time outside.

In Taiwan's summer peak electricity consumption, over 40% of energy is used for building air conditioning.

Statistics reveal that over 40% of peak electricity consumption during Taiwan's summers is dedicated to building air conditioning. While the government has set a goal of net-zero emissions by 2050, the focus has largely been on improving the efficiency of active systems like air conditioners and lighting. However, the article argues that these systems merely move heat from indoors to outdoors and have a limited lifespan, necessitating a greater emphasis on passive energy-saving strategies.

Passive energy-saving measures, such as external wall insulation and thermal insulation building materials, are perhaps more important.

Passive measures, such as external wall insulation and the use of thermal insulation building materials, are presented as a more sustainable solution. These methods work by blocking direct solar radiation and reducing heat transfer through walls, thereby keeping interiors cooler. They also prevent cold air from escaping, further reducing the need for active cooling. Unlike air conditioners, which require regular maintenance and replacement, passive insulation can last as long as the building itself, offering a truly long-term, maintenance-free approach to energy conservation.

Passive energy-saving facilities can be installed during building construction or renovation, and their lifespan is basically the same as the building's lifespan.

The article champions the use of 'green building materials,' particularly those made from recycled waste products like fly ash, waste glass, and reservoir silt. These materials, when certified with the 'recycled green building material label' by the Ministry of the Interior, offer not only environmental benefits through resource recycling and reduced carbon emissions during production but also provide effective insulation and soundproofing. The author strongly recommends these 'high-quality recycled green building materials' for all new construction and renovation projects as a crucial first step toward achieving net-zero buildings, especially urging government initiatives in urban renewal projects.

These recycled green building materials not only have basic resource recycling and environmental benefits but also provide insulation and energy-saving effects.
