GRESB Results Event Germany –

18.10.2017 in Hamburg


Join us on 18 October in Hamburg for the launch of the 2017 GRESB Real Estate Assessment Results where we provide insights into the ESG performance of global real estate portfolios, hosted by Union Investment in partnership with ES EnviroSustain.

This annual event presents a unique opportunity for the European real estate community to engage on the current state of sustainability in the sector, review emerging trends from the annual assessments, and celebrate the continued growth of the movement.


Following the results presentations, we will recognize the achievements of the Regional Sector Leaders, release the Global and Regional Results Snapshots with new analysis into sustainability best practices and explore what investors consider to be the most critical issues for ESG integration in real asset investments.

16th VGIE-Conference,
14 Sept 2017 in Berlin

The building branch accounts for almost 40 percent of the total energy consumption in Germany. Almost a third of the total energy use in Germany may be attributed to heating, about 95% of which is used for the heating of buildings constructed prior to 1983. Given that new buildings are already subject to enhanced requirements on insulation and building services thereby lowering their proportion in total energy consumption, it becomes obvious that only improvements to existing buildings will achieve an effective reduction in energy consumption and carbon footprint.

Better energy efficiency for existing building is therefore a must; but how can the transformation within the existing building sector be accomplished and still remain attractive to owners and investors? This is the theme of the 16th VGIE-Conference, 14th September 2017 in Berlin, at the Park Inn Hotel at Alexanderplatz. The organizer is the VGIE – a network of experts on promoting the exchange of interdisciplinary scientific knowledge within the renewable energy and innovative technology sectors. In the light of the forthcoming challenges associated with the building and energy policies of 2050, VGIE invites you to attend talks and discuss innovative, integrated strategies to improve the design, implementation and operation of buildings and urban districts. The conference addresses designers, developers, representatives of cooperative building societies, building operators, facility management professionals as well as procurement and contracting executives.
