Standard Bank

Project Information NrG completed one of the largest hybrid hot water systems in Southern Africa for Standard Bank building in Braamfontein. The building forms part of the cluster of buildings in the CBD of Johannesburg and boasts an employee count well within the thousands. The hot water supplied by the system ensures that the 24-hour gym facility is supplied with hot water at all times for its large staff complement. The system utilises solar thermal, heat pump and electrical technologies as heat sources with a complex cascaded storage system, all monitored by an online control system. The sheer size and complexity of the hybrid system earned NRG both a win and nomination of the prestigious Southern African Association of Energy Efficiency Energy Company of the Year Award in the years of 2010 and 2011 respectively.
