Stainless steel is a group of iron-based alloys containing at least 10.5% chromium, with added elements like nickel and molybdenum to enhance corrosion resistance, heat resistance, and fabricating properties. The American Iron and Steel Institute (AISI) recognizes over 60 grades of stainless steel. Chromium forms a protective oxide layer on the surface, preventing rust by blocking oxygen from reaching the iron base.
“ Society is increasingly concerned about the health of the natural environment and the impact of materials on ecosystems. This awareness has led to the concept of “greening,” where the environmental performance of materials influences selection decisions.
The production process begins with selecting raw materials, which typically consist of 75-85% recycled stainless steel scrap and alloying elements like chromium, nickel, and molybdenum. This mixture is melted in an electric furnace and transferred to an Argon Oxygen Decarburization (AOD) vessel to reduce carbon content. Gaseous emissions are collected, and dust is recycled to recover metallic compounds. The molten stainless steel is then cast into slabs or ingots, which are further processed into various products through rolling, forging, or drawing.
Criteria for Evaluating the "Greenness" of Stainless Steel
A variety of criteria can assess the environmental performance of stainless steel, including:

Architectural Digest gợi ý Cloud Dancer phù hợp với plush fabrics và những hình khối “mềm”, tránh cảm giác cứng/rigid; họ liên hệ nó với cảm giác “weightless fullness” (nhẹ nhưng đầy) [3]. Đây là cơ hội cho các dòng vải bọc, rèm, thảm, bedding: màu trắng ngà làm nổi sợi dệt và tạo cảm giác chạm “ấm”.Pantone has announced the PANTONE 11-4201 Cloud Dancer as the Color of the Year 2026: a "buoyant" and balanced white, described as a whisper of peace in the midst of a noisy world. This is also the first time Pantone has chosen a white color since the "Color of the Year" program began in 1999. Pantone calls Cloud Dancer a "lofty/billowy" white tone that has a relaxing feel, giving the mind more space to create and innovate [1].

The Netherlands is one of the most vulnerable countries to climate change, with about a third of its area lying below sea level and the rest regularly at risk of flooding. As sea levels are forecast to continue to rise and extreme rains increase, the government is not only strengthening dikes and tidal culverts, but also testing new adaptation models. Floating housing in Amsterdam – typically the Waterbuurt and Schoonschip districts – is seen as "urban laboratories" for a new way of living: not only fighting floods, but actively living with water. In parallel with climate pressures, Amsterdam faces a shortage of housing and scarce land funds. The expansion of the city to the water helps solve two problems at the same time: increasing the supply of housing without encroaching on more land, and at the same time testing an urban model that is able to adapt to flooding and sea level rise.

Kampung Admiralty - the project that won the "Building of the Year 2018" award at the World Architecture Festival - is a clear demonstration of smart tropical green architecture. With a three-storey "club sandwich" design, a natural ventilation system that saves 13% of cooling energy, and a 125% greening rate, this project opens up many valuable lessons for Vietnamese urban projects in the context of climate change.

In the midst of the hustle and bustle of urban life, many Vietnamese families are looking for a different living space – where they can enjoy modernity without being far from nature. Tropical Modern villa architecture is the perfect answer to this need. Not only an aesthetic trend, this is also a smart design philosophy, harmoniously combining technology, local materials and Vietnam's typical tropical climate.

Amid rapid urbanization and global climate change, architecture is not only construction but also the art of harmonizing people, the environment, and technology. The Bahrain World Trade Center (BWTC)—the iconic twin towers in Manama, Bahrain—is a vivid testament to this fusion. Completed in 2008, BWTC is not only the tallest building in Bahrain (240 meters) but also the first building in the world to integrate wind turbines into its primary structure, supplying renewable energy to itself [1]. This article explores the BWTC’s structural system and design principles, examining how it overcomes the challenges of a desert environment to become a convincing sustainable model for future cities. Through an academic lens, we will see that BWTC is not merely a building but a declaration of architectural creativity.
