Union Investment provides visibility into the sustainability of its properties
Union Investment teamed up with atmosgrad° to develop “atmosphere”, a new sustainability label that allows tenants, investors and other market players to see the sustainability performance of a property at a glance.
“atmosphere” – the new sustainability label
Union Investment’s Real Estate segment first embedded sustainability into its business strategy more than ten years ago. Over the intervening period, we have been measuring, analysing, planning and improving, steadily moving closer to the German government’s declared goal of making the nation’s building stock virtually climate-neutral by 2050. We have now taken a major step forward with our new sustainability label “atmosphere”, which captures the environmental pathways of our properties and renders the sustainability of buildings visible.
In future, a key performance indicator will allow tenants, investors, managers and other market players to see how a building or portfolio has been assessed against specific sustainability criteria. This score also shows what proportion of the “Manage to green” strategy has already been implemented. Union Investment created the “Manage to green” strategy in 2018 to help it systematically achieve the goal of making its building stock climate-neutral by 2050.

Why create a sustainability label for buildings and portfolios?
Rationale and challenges
Basis
The sustainability label is underpinned by our “Manage to green” strategy. The key performance indicator on the label shows the extent to which the sustainability criteria have already been met.
Criteria
- 40% of the achievement target consists of the results of the Sustainable Investment Check (SI Check). This evaluation system was introduced back in 2010 and covers a number of categories, including data related to building structure, in-use measures and user comfort.
- A further 40% relates to energy and water consumption, waste and CO2 emissions. It is therefore possible to see exactly how the building measures up in terms of environmental performance.
- 20% relates to governance factors at company and portfolio level (e.g. strategy or green building certificates).
Levels
The underlying calculation method allows the sustainability label to be awarded not only at property level, but also at fund level by aggregating all properties. This provides transparency for tenants and investors alike, and also supports management control.
Challenge of existing buildings
For new build projects, legal requirements are already in place to ensure certain energy performance levels are met. However, there are no benchmarks for existing properties. The new label makes a comparison possible for the first time and enables us to define property-specific strategies for achieving climate targets.
Different use types
From shopping centres and hotels to logistics properties and offices – different use types call for different approaches. Our sustainability label differentiates between each category, but always with the environmental pathway as a consistent criterion.
Updates
The label is updated annually across properties in order to document the progress achieved.
Classification
The criteria developed for the label are deliberately designed to be broad enough to accommodate the requirements arising from the EU Action Plan. They can also be modified if tougher regulations are put in place.
Commitment within the industry
To provide transparency for investors and the market, an industry-wide standard would be required. The “atmosphere” label could serve as a template.
The label in practice
A sustainability score is calculated for each property in the portfolio. The buildings are given an electronic label, wherever possible. The Holzmarkt 1 pilot property in Cologne is a particularly sustainable building and one of the first to display the label on a digital pillar.

The seven-storey and approx. 19,000m² office building was acquired by Union Investment in 2015 on completion. The special sustainability features of the property include an energy-optimized perforated facade, green spaces on the roof and in the courtyard, disability access to all floors, the use of district heating and much more.
