The heart of HIAG’s business model is the long-term development of real estate in our own portfolio. Due to the use and conversion of the existing building substance, our business model is sustainable in and of itself, since we are making an important contribution to the circular economy and creating room for people and companies to flourish when we develop new destinations. We always take the technical possibilities for creating energy-efficient buildings into account as part of our site and redevelopment strategy and expand our production capacities for renewable energy in a targeted manner.


At the Kunzareal site in Windisch, HIAG installed one of the largest photovoltaic facilities in the Brugg-Windisch region on the roof of the former Swiss Army recruitment centre, which is now a FARO Foundation residence.  With a surface area of 1’300 m², it allows for maximum electricity production of 194 Mwh using 794 modules. The resulting total amount of CO2 emissions avoided since 2013 was approximately 712 tons of CO2 as at the end of 2019. Furthermore, “The Hive” campus in Meyrin has been illuminated by solar power-supported LED lights since 2019. The solar cells collect the sun’s energy during the day, store it in a battery and release it autonomously at night via LED lamps. This saves 1'118 kWh of electricity and 30.2 kg of CO2 every year. In addition, the photovoltaic facility at the “Hive 2” building produced 19’657 kWh of electricity in 2019. For new buildings, HIAG always checks whether the roof areas are suitable for solar panels and systematically expands the production of renewable energies on large roof areas in its own real estate portfolio.

Hydroelectric power

A few of HIAG’s sites are located on the courses of rivers, and have hydroelectric plants that were important energy sources for previous industrial operations. Due to their integration in site structures, we have gradually taken over the operation and maintenance of these facilities, repairing and modernising the plants in recent years. Today, they are being used again to produce electricity. In 2019, five small hydroelectric plants with an installed capacity of about 2 MW generated a total of about 6’534’610 kWh of electricity from renewable energy, which corresponds to the average annual requirement of about 1’600 homes.

Every step of real estate development offers room for innovation, from the acquisition to site development, operation, portfolio and asset management and finally the sale. This is the case on both the technical as well as the social and environmental level. An example of this is the “Hive Innovation Lab” in Meyrin: using a concept developed jointly by Hewlett Packard Enterprise and HIAG, it has created a flexible and interconnected ecosystem that offers start-ups attractive space for interdisciplinary cooperation and innovation.

Quality in architecture and urban planning

HIAG places value on urban planning and architectural quality when developing its sites, and particularly for parks, where a unique biodiversity can develop. They are part of urban planning, as high-quality living space is created around these parks. A habitat with its own flora and fauna was created at “The Hive” campus in Meyrin, for example. Around 70 kg of honey are produced annually from five beehives.

UN sustainable development goals

The United Nations set forth 17 sustainable development goals in its 2030 agenda, which can be recognised in many of our developments. That way, HIAG’s sites can become the centre of meaningful entrepreneurial initiatives. In particular, the goals of “Industry, Innovation and Infrastructure”, “Sustainable Cities and Communities” and “Responsible Consumption and Production” are at the heart of our understanding of site development.
