The predicted economic impacts of climate change play a key role in directing policy responses to a warming planet. Of particular importance is a figure called the social cost of carbon (SCC), which gives a dollar amount to each ton of carbon emissions—and a figure derived by the Obama administration of $21 per ton of carbon is drawing sharp...

The Finnish company Upofloor’s PVC-free LifeLine CS commercial resilient sheet flooring uses a tough wear layer and low-emitting materials to create a durable surface. It is appropriate for healthcare, education, and other public spaces prone to consistent, heavy foot traffic.

Distributed in North America through Altro,... Read more

R-value, which measures resistance to heat transfer in insulation, is one of the most popular building metrics—but what it does and doesn’t tell us is often misunderstood.

There are two test methods that are important to measuring R-value. The first, ASTM C518, is relevant to single materials. In this test, a sample of the material is... Read more

By Paula MeltonIt’s been five years since our super-sized housing market collided with the iceberg of reality and began its long descent, eventually pulling the global economy into the frigid depths along with it. The magnitude and origins of this collapse are making the recovery a slow one—and uniquely painful for those working in building... Read more

The urban heat island effect created by large areas of pavement and buildings can cause many problems, from increased energy use to reduced water quality. A new study from the National Center for Atmospheric Research (NCAR) suggests that expanses of paved surface may also worsen air quality in coastal cities like Houston, where... Read more

Manufacturers are improving photovoltaic (PV) module efficiency and bringing down costs, but the most efficient PV systems today use silicon crystal technology that is decades old. At the same time, thin-film technologies offer a cost-competitive solution with some advantages but with lower efficiency. With the hundreds of... Read more
