Low-E stands for low emissivity, and these windows are constructed to minimize heat transfer through the glass. Since windows are essentially huge holes in the walls of a building, choosing a low-E window design that’s appropriate for local climate and architecture can greatly increase a structure’s thermal efficiency, while reducing energy use and utility costs.

Air travel can present an efficiency dilemma. Trips that wouldn’t be possible by any other means because of time or distance are suddenly viable – though when it comes to manufacturing and fuel resources, airplanes admittedly aren’t the most efficient mode of transportation. But Boeing’s newest passenger jet, the 787 Dreamliner, aims to take a […]

The new Blue Ridge Parkway Destination Center has just been completed in North Carolina. It’s a beautifully designed building that is also highly efficient — it will use 75% less energy than a comparable conventional building. The building has Trombe walls: a very clever feature that will reduce the building’s heating load by 35% alone!
