The third study visit took place on 12th & 13th September in Hamburg with the participation of numerous MOLOC partners. Partners were officially welcomed by the Deputy Mayor of Hamburg Henrick Lesaar who emphasized the importance of study visit in order to learn from each other's knowledge and experience. ZEBAU, the Centre for Energy, Architecture, Planning and Environment, presented progress of Hamburg local analysis, which will help in the design of the action plan in 2019. It will focus on an industrial and commercial area aiming at creating sustainable and efficient actions through synergies between companies.

In the afternoon, MOLOC partners went to Aurubis, the biggest copper Producer in Europe. They visited the company and learnt from the partnership with HafenCity. The idea is to recover heat from industrial production and supplu the Eastern part of HafenCity in heating through district heating network. It will save more than 4500 tons of CO2 every year.

The second day, MOLOC partners went to HafenCity area for présentations and interesting visit. HafenCity represents one of the largest urban projects in Europe and covers 155 hectares. In the 1990's, the port left its original site, next to the inner city, to move to the South part. After few years of brownfields, the City decided to extend the inner-city to the riverbanks of the Elbe. In the future, the area will represent 45 000 jobs and 70 000 housing units. The Western part is almost done whereas the Eastern part is still Under construction. The City invested almost 8.5 billion euros. Environmental issues are at the core of the HafenCity project. The whole area is concerned by flood. Public spaces, housing, parkign have been designed to adapt to the rise of sea level. Energy efficiency is also a prior concern to all buildings. This project represents a flagship for Hamburg towards a low-carbon city.
