The Aesthetic of Rust: Weathering Steel

Written by

Weathering steel, more commonly referred to by the U.S. Steel tradename Cor-Ten™, is a group of steel alloys that develop a stable oxidation requiring no additional coating. Upon exposure to normal environmental stresses, it acquires a dense, dark brown colored barrier layer that protects it from further oxidation.

Many people like the natural appearance and simple maintenance that weathering steel fabrications provide. In addition to being used in structural framing, roofing and siding panels, weathering steel is often used for decorative fabrications, including signage and sculptures.

Written by

In just about every part of the world not the United States -- the only country that dares to use the word "soccer" -- the sport of football makes for extremely important events. It is no surprise that many football stadiums feature impressive architectural design, such as the Bird's Nest National Stadium for the 2008 Beijing Olympics by Herzog & de Meuron and the World Cup 2010 stadium in Johannesburg, South Africa, by Populus (formerly HOK Sport) with local firm Boogertman & Partners.

Maintenance Tips: Central Air Conditioner

Written by

Perform a few simple maintenance tasks, schedule professional HVAC service on a yearly basis, and enjoy efficient performance and trouble-free operation of your central air conditioner throughout its expected lifespan (and maybe longer).

Invented after the turn of the 20th century but not mass-produced for homes until after World War II, the air conditioner has increased our comfort and modified the landscape from coast to coast. According to the U.S. Department of Housing and Urban Development (HUD) 2009 American Housing Survey (AHS), 75% of owner-occupied housing in the United States has a central air conditioning unit. The average life expectancy of these air conditioning units is 10–15 years, according to the Study of Life Expectancy of Home Components, prepared in 2007 by the National Association of Home Builders (NAHB). Neglecting your unit will result in a shortened lifetime, costly repairs, and higher energy costs due to inefficient operation. Maintain your unit and you will extend its lifetime and keep repair and energy costs low while ensuring your comfort on those hot summer days.
