Neue Messe München is an exhibition center in the Messestadt Riem area in the eastern district of Munich Trudering-Riem built in 1994 until 1998. It is operated by Messe München. Location and transport The exhibition center was built on the northern half of the former Munich-Riem airport. It is bordered by the south Willy-Brandt-Allee and the residential development of Riem Messestadt and Riem arcades, there are also the two underground stations for the U2 line, Messestadt West and East located there. The Bundesautobahn 94 passes to the north and the exhibition grounds are connected with two highway exits. Further north is the S-Bahn station in Munich-Riem, where the transportation of freight to the fairgrounds runs since 2001. A direct connection of the S-Bahn to the fairgrounds is being discussed throughout the course of the construction of the Erding Ring Closure, which would also allow for a direct connection to the new Munich Airport. Terrain and buildings The heart of the exhibition grounds are 16 exhibition halls with a total of 180,000 m2 of exhibition space with the added, when needed, additional 360,000 m2 of open area to the north and east of the site. The two main entrances are located on the western and eastern end, these are connected by a 650 m long and 35 m wide atrium, which allow access to the twelve halls. Located at the western entrance is the International Congress Centre (ICM), the exhibition hall and the Messesee. An 86 meter high fair tower stands at the eastern entrance. Architects were Bystrup Architecture Design Engineering, Bregenhøj + Partners, Kaup, Scholz, Jesse + Partner. At the third entrance, to the north, a press center with the World Cup fountain was established for the 2006 FIFA World Cup, it has since been used by Messe München. Upon the completion of construction, the world's largest photovoltaic system was installed on the roof of the exhibition halls. The system produces about 1,000 MWh of electricity annually. At the north-eastern and south-western end of the show, there are two parking garages with a total of about 5,700 parking spaces. The outdoor area is used as additional parking space or additional exhibition space for major fairs, such as Bauma. In May 2016 two more halls will be built northeast of the existing building. The €93 million expansion should have been started as early as 2013 according to the Messe München GmbH,
