When The Palazzo was first being constructed, Las Vegas Sands had an opportunity to build it in a way that would be environmentally friendly as a LEED certified, Leadership in Energy and Environmental Design, building. Based on this initiative, Las Vegas Sands began to take on several opportunities in sustainability for new and existing buildings. As part of the initial group that led to the development of Sands ECO360, John Hess, corporate executive director of Engineering, provides technical support during all phases of construction for new buildings and major renovation projects.
