  • Rethinking the All-Glass Building

    Feature Article

    Is it time to end our love affair with the all-glass building? A lot of proponents of high-performance, green design certainly think so-while other respected architects, including some leading green designers and energy experts, argue that all-glass can work well if done right.

  • Avoiding the Global Warming Impact of Insulation

    Feature Article

    Insulation is key to reducing carbon emissions from buildings. But the blowing agent in extruded polystyrene and spray polyurethane foam offsets much of that benefit.

  • Passive House Arrives in North America: Could It Revolutionize the Way We Build?

    Feature Article

    The Passive House standard, imported from Germany, sets a high bar for energy performance in buildings. But some see it as inflexible and inappropriate for some U.S. climates.

  • Design for Adaptation: Living in a Climate-Changing World

    Feature Article

    Even if we stopped emitting greenhouse gases tomorrow, rising global temperatures would still bring major changes to the climate system and our way of life. This article offers solutions for designing buildings that not only mitigate our impact on the global climate, but also adapt to the changes that are coming-and those that are already here.

  • Sharing the Skyline with Birds

    Explainer

    Buildings are major killers of birds, but thoughtful design can help.

  • How R-Value Is Calculated

    Explainer

    You know what R-value is, but how do they figure it out? And is it really a reliable measure of insulation performance?

  • How Insulation Works

    Explainer

    Understanding how insulation works can help us find the right material for a particular project.

  • Thermal Bridging

    Explainer

    Thermal bridging, when one material conducts heat much better than materials around it, can reduce the effectiveness of insulation to a surprising extent.
