  • Shaky Foundation: Why the U.S. Lags Behind in Building Science Research

    Energy efficiency is the next frontier of design and construction, but due to underinvestment and the lack of a national agenda, America isn't leading the way to high performance building.

  • EarthWall is a combination of structural rammed earth and post-tensioning rods anchored to a concrete foot, which allows the wall to receive lateral weight as well as withstand wind and earthquakes. The earthen mixture, developed by architect Tom Ward, is made up of 10 percent on-site soil, 80 percent locally sourced gravel byproduct, and 10 percent cement. While the post-tensioning system is made of steel, EarthWall uses less of this material than traditional grid systems. The rods, retaining plates, and nuts can all be reused, leaving only the bond beam and footing as waste.


    A combination of structural rammed earth and post-tensioned rods, EarthWall is strong, locally sourced, and recyclable.

  • Green Wall Systems: Active Phytoremediation Wall System

    Green wall systems are a balm for cubicle-weary office workers as well as a great energy-saver. The Center for Architecture Science and Ecology creates a new modular green wall system that bares the plants roots and increases air-cleaning efficiency.

  • 2009 R+D Awards

    Introducing the third annual ARCHITECT magazine R+D Awards.

  • Solar tube density varies on the different faces of the tower. The highest concentration is on the south façade, in an effort to harness the maximum amount of solar energy to convert to steam power.

    Oasis Generator

    SOM's Chicago office engineers a desalinization tower that aims to make the seaside desert a bit more habitable.

  • Ecoworx backing for broadloom carpet was engineered as a cradle-to-cradle product, which can be reclaimed at the end of the product's life cycle, broken down into its component pieces, and completely recycled into new commercial-grade carpet.

    Ecoworx Backing for Broadloom Carpet

    Shaw Industries created a cradle-to-cradle solution for broadloom carpet backing.

  • A mock-up of the SFIS with bundled plastic bottles. Most plastic water bottles are discarded with the caps on; capped, empty bottles are airtight and can be placed within a concrete structure to create a void. Hydrostatic pressure from wet concrete will only nominally reduce the air volume inside the bottles.

    Sustainable Form-Inclusion System

    Skidmore, Owings & Merrill design a prototype system that uses plastic bottles, bags, and other compressed waste to lighten and fill spaces in concrete slabs.

  • TWA Building Renovation

    At 135,000 square feet, the TWA Corporate Headquarters Building in Kansas City, Mo., is the largest project that El Dorado has completed to date, and the only one already listed on the National Register of Historic Places.

  • Green Roofs for Healthy Cities Educates Building Professionals

    Steven W. Peck, founder and president of Toronto-based nonprofit association Green Roofs for Healthy Cities, shares his thoughts about the benefits of vegetated roofs.

  • Empty Workspaces Aren't Green

    In today's era of mobile technology, offices often waste energy by sitting empty.
