[originaltext]Architects, engineers and building supervisors will soon be able

Architects, engineers and building supervisors will soon be able to quickly collect information that once took weeks to measure and process. Scientists have developed a device to gather information about building interiors— the design and exact measurements of a building. The device requires only one pass through a building to create a three-dimensional model of the structure. In other words, the model shows an object’s height, width and depth. The device is also able to collect other valuable information related to the building’s energy usage. The first thing you need to know is the exact shape of all rooms in the building. You have to consider the size and position of heating and cooling equipment, windows and doors. Another consideration is the placement of electrical outlets— the areas where electrically-operated equipment can be connected to the power supply.
