HIAG is already making consistent use of the technological possibilities for realising energy-efficient buildings and reducing CO2 emissions in its real estate portfolio. In parallel, the production capacities for renewable energies will be increased systematically across the entire real estate portfolio. The joint venture HIAG Solar, launched at the beginning of 2021, will have three newly installed photovoltaic systems on HIAG properties with a total output of 1 MWp in operation by the end of fiscal 2021. With a planned module area of around 65,000 m2 and an output of around 10 MWp, HIAG Solar is aiming to become a major solar power producer in Switzerland in the medium term. The sustainability report (ESG), published for the first time in fiscal 2020, will be continuously increased and will be based on the Global Reporting Initiative (GRI) standard starting in the 2021 reporting year. The United Nations Sustainability Goals (SDGs), which are already recognisable in many of HIAG's developments, also remain important benchmarks.
