Calculation of environmental indicators for Swiss Real Estate

The key figures are based on measured energy consumption values. The majority of consumption values are collected via consumption invoices from energy suppliers and utility bills from property managers. To a small extent, properties are equipped with automated data transmission. The balance year is the calendar year.

Incomplete or missing consumption values were supplemented by estimates on a case-by-case basis. In some cases, the measured value from the previous year was used as an estimate for fuels and heat consumption. For non-existent values for «electricity in general», average values were also added on a case-by-case basis.

The reported energy consumption values for fuels and heat are climate-corrected according to heating degree days. For the heating degree days, the data source of the HEV Schweiz association (external link) was used.

The calculation and presentation of greenhouse gas emissions were carried out according to the rules of the SIA 380:2016 standard. The emission coefficients according to KBOB 2016: life cycle assessment data in the construction sector 2009-1:2016 (external link) were used for the calculation of greenhouse gas emissions. 

The total area of completed buildings is the total area of the properties of the real estate investment products for the respective balance sheet year (calendar year).

Finished buildings do not include buildings in progress, construction projects, building land and demolition properties as well as individual properties that are due for sale or complete renovation in the near future. Property purchases in the financial year and construction projects completed in the financial year are not included; these are only recognised in the balance sheet as completed buildings in the following year. 

The energy reference area (EBF) calculated from the rentable area (VMF) is used as the area type. The conversion factors by building category of the Ordinance on Collective Investment Schemes (KKV) were used to calculate the energy reference area from the rentable area.

The degree of coverage is the measure of the proportion of areas for which energy consumption values for space heating and general electricity were collected in the billing period in relation to the area of all completed buildings.

The share of the measured values in the result is shown according to the specifications of the Conference of Managers of Investment Foundations (KGAST).

Greenhouse gas emissions are calculated and presented according to the rules of the Greenhouse Gas Protocol and the Swiss standard SIA380:2022 - based on climate-corrected energy consumption values.

The owner-controlled emissions are assigned to Scope 1 for the fuels used and Scope 2 for district heating and electricity.

For the calculation of greenhouse gas emissions, the emission coefficients according to the location-based approach of the Greenhouse Gas Protocol (in kilograms CO₂ equivalent / KWh) are applied in accordance with the «REIDA CO₂e-report – methodological principles, version 1.2». These are average values for Switzerland for the balance period (calendar year).
