New Tool Maps Buildings' Energy Efficiency by George Putic Architects, engineers and building managers will soon be able to quickly collect data about building interiors that once took weeks to measure and process. A backpack-mounted device, developed by a group of scientists at the University of California, Berkeley, will require just one pass through the building to create not only a 3D model but gather other valuable information related to the building's energy efficiency. VOA's George Putic reports. __________________________________________________________________ [1]http://www.voanews.com/media/video/new-tool-maps-buildings-energy-ef ficiency/2660475.html References 1. http://www.voanews.com/media/video/new-tool-maps-buildings-energy-efficiency/2660475.html
