Sustainability
Company and project level

Sustainability Projects & Company

We take responsibility not only for the environment but also for society and the economy. To this end, we implement specific sustainability measures at both the corporate and project levels. Through these efforts, we aim to fulfill our responsibility as a company and have a positive impact on the communities and environments in which we operate. Among other initiatives, we actively advocate for the use of environmentally friendly materials and the implementation of renewable energy sources, as well as promoting the integration of social aspects into our projects.


ESG measures
for yielding residential platform

ZAR’s Manage-to-Green strategy follows a differentiated, two-phase approach to systematically improve energy efficiency, reduce asset-related risks, and create long-term value potential across residential real estate portfolios.

Phase 1 – Performance & Optimisation

  • Focus on optimizing existing heating systems through adaptive hydronic balancing
  • Deployment of sensors and AI-driven software to analyse and learn property-specific consumption patterns
  • Real-time monitoring of heat demand, weather conditions, usage behaviour and system performance
  • Optimisation of flow temperatures and volume flows across heating circuits
  • Reduction of energy consumption and operating costs, with energy savings of up to 40%

The optimisation achieved in Phase 1 forms the foundation for the transition to CO₂-neutral operation in Phase 2, effectively allowing EPC upgrades to A-C level

Phase 2 – Net Zero Transition

  • Upgrade to CO₂-neutral building operation through the installation of heat pumps and photovoltaic systems
  • Replacement of fossil fuel-based heating systems and boilers
  • Integration of PV-generated electricity to power heating systems and optimise self-consumption
  • Intelligent control of heat generation and storage to ensure stable and efficient operation
  • Achievement of EPC improvements to A-C level, enabling long-term regulatory compliance and sustainable asset positioning
