Sustainability as an integral component of our core processes

From idea to implementation: We incorporate sustainability aspects into our core processes and always take a building’s entire life cycle into account.

Pre-project and acquisition

Each project is evaluated at an early stage on the basis of various environmental, social and economic criteria. We only pursue projects with a high sustainability value.


During development, Ina Invest requires all projects to meet the Swiss Minergie standard at a minimum from an energy point of view. In terms of material, we focus particularly on the use of renewable resources, such as wood. We carefully select recognised sustainability certificates and apply the associated standards in line with local and project-specific conditions.


The fulfilment of sustainability criteria is also the top priority in construction. Project-specific environmental concepts are defined and implemented in order to prevent or limit environmental emissions. Material approval procedures guarantee the use of safe and environmentally friendly materials. Ina Invest maintains these procedures by training construction personnel and utilising a targeted partner selection process throughout the entire procurement process.


The sustainability quality of Ina Invest's project portfolio is reflected in the excellent GRESB rating. The optimisation of each project is ensured with respect to energy consumption as well as water and waste management. The users benefit from activities relating to ESG (Environment Social Governance) issues that are designed to increase community involvement, social interaction and health and comfort.


Ina Invest plans to register all projects in a material database in order to be able to determine the material quantities used and their current market value at any time. Thanks to transparent data preparation, the materials can be sold prior to the actual dismantling phase and the separation of individual materials on the secondary raw materials market.


We plan to use the GRESB methodology to continuously optimise our portfolio’s social and environmental performance. GRESB is the leading system for assessing the sustainability performance of real estate companies and real estate portfolios. For 2020, Ina Invest has achieved first place in its peer group with 92 out of a possible 100 points and thus "Green Star" status
