Free app enables facility managers to view LED lighting savings

A free smart device app and Web-based tool has been developed to enable anyone in South Africa to measure how much energy, cost and greenhouse-gas emissions savings will be achieved by switching to light-emitting diode (LED) lighting, while ensuring the quality of luminescence is maintained or improved. A team from State-owned South African National Energy Development Institute (Sanedi), supported by German development agency GIZ and the South African German Energy Partnership, investigated three public sites in South Africa used by government agencies or departments using the app, and each site demonstrated significant savings in energy and costs, as well as rapid payback periods of up to two years, Sanedi Renewable Energy Centre of Research and Development manager Dr Karen Surridge said on October 28.
