In 2010, USTDA worked with representatives of the public and private sectors in South Africa to reduce energy consumption by investing in energy efficient technologies. This program included a training session in South Africa and a reverse trade mission that introduced delegates to energy efficient technologies, equipment, and best practices. Based on this experience and a relationship forged during the reverse trade mission to the United States, the General Manager of Store Development for Pick n Pay, a grocery chain in South Africa with over 700 stores, placed a breakthrough order for energy efficient skylights from Sunoptics (Sacramento, CA) to enhance natural lighting for its new flagship store that opened in October 2010. Use of these patented prismatic skylights is estimated to reduce energy costs by 70% to 80%. It is anticipated that the initial sales for Sunoptics will lead to future orders in South Africa.
