place for the prospective team's inaugural season. After much consideration of possible other sites both in Downtown Atlanta and in the suburbs, it was decided that the Omni would be demolished in 1997, and a new arena would be built in the same location; the Omni was demolished on July 26, 1997. The Hawks split their games between the Georgia Dome and Alexander Memorial Coliseum for the next two seasons while Philips Arena was under construction. Philips Arena held its first event with a September 1999 concert by the musician Sir Elton John. The Omni's "center-hung scoreboard" now hangs in the lobby of Philips Arena, where it still displays the Omni's logo along with those of Philips Arena, the Hawks, and the Thrashers (who never played in The Omni). The scoreboard still functions and displays information relevant to the game taking place in the arena. On April 2, 2009, Philips Arena achieved LEED for Existing Building: Operations and Maintenance certification as specified by the United States Green Building Council (USGBC). It was the world's first LEED certified NBA/NHL arena. It has been nicknamed the "Highlight Factory", due to the number of exciting plays, or highlights, that occur and Philips' history with lights and electronics. On March 14, 2008, an EF2 Tornado struck near the Arena as part of a tornado outbreak that hit the city. The arena only received minor exterior damage. Events The arena hosted the NBA All-Star Game in 2003 and the Atlantic Coast Conference men's basketball tournament in 2012. The first playoff game in any professional league played in Philips Arena was in 2005, when the Georgia Force of the Arena Football League hosted, and won, its first home playoff game. The first NHL playoff game in Philips Arena was in 2007, the Thrashers' only appearance in the Stanley Cup Playoffs. The first NBA playoff game in Philips Arena was in 2008, when the Hawks made the 2008 NBA Playoffs after an eight-season drought of missing the playoffs. On April 10, 2011, the Thrashers lost to the Pittsburgh Penguins, 5–2, in their final game. Tim Stapleton scored the final goal for the Thrashers in team history. The venue had been named the site of the 2005 Southeastern Conference Women's Basketball Tournament; however, when the NHL announced in early 2004 that the 55th NHL All-Star Game, scheduled for February 2005 would be held in Atlanta, arena officials withdrew
