    The topic of law is dealt with in this committee in many different ways. Focal points include tenancy law, investor protection, brokerage law and data protection and the associated effects on the real estate industry.
  • Logistics Property Committee
    After the committee succeeded in raising the economic potential of logistics real estate, strengthening its importance in public perception and optimising it as an asset class by increasing transparency and improving the data situation, the focus is now on integrating the aspects of climate protection, digitalisation and changing mobility and consumer behaviour.

Innovation Think Tank

The Innovation Think Tank (ITT) provides impulses for the entire real estate industry. The core objective of the ITT is the systemic networking of all relevant actors and the committees of ZIA.

In this way, the ITT makes a significant contribution to more social, ecological and economic sustainability in all living spaces. (More information in German)

Task Force Energy

The energy turnaround is one of the core goals of the real estate industry, but it can only succeed with measures that make economic sense and are open to technology. For this reason, ZIA and its Task Force Energy have developed proposals for the real estate industry to achieve climate policy goals and presented the position paper „Real Estate Industry & Energy“. It deals with the energy policy of the European Union, the federal government and the states with regard to real estate. (More information in German)

In order to deal with and intensify the handling of the effects of the Corona pandemic at the end of the first half of 2020, the Board of Directors and the Executive Committee of ZIA convened a Retail Task Force under the leadership of Andreas Hohlmann, Managing Director at Unibail-Rodamco-Westfield (URW Germany).
