Energy balance of yield-producing real estate
In terms of operating and maintaining its own income-producing real estate, Allreal endeavours to keep the strain on the environment as low as possible. For its income-producing properties, the company measures and analyses energy and water consumption based on the internationally accepted recommendations of the European Public Real Estate Association (EPRA). The data systematically gathered for the first time in 2012 provides an inventory of the current status, and a multi-year comparison is of relevance for the definition, implementation and control of sustainable measures taken in order to lower energy consumption and the connected reduction of pollutant emission.
The calculation of energy and water consumption takes into consideration income-producing properties for which the necessary information is available across a twelve-month accounting period. In the 2017 financial year, this applies to 20 residential properties at a total market value of CHF 818.4 million and 37 commercial properties at a total market value of CHF 2,682.9 million (2016: 18 residential / 37 commercial properties). Comparability is, however, restricted as both the composition of the portfolio and the parameters differ from year to year.
Total energy consumption (electricity and heating) of the surveyed properties in the year under review amounted to 72.8 million kilowatt-hours, corresponding to an average consumption per square metre of 105.2 kilowatt-hours (2016: 72.7 million kWh / 104.1 kWh). These values correspond to a CO2 equivalent of in total 20,425 tons or 30 kilograms per square metre (2016: 19,903 t / 28.7 kg).
Water consumption of the surveyed properties amounted to 414,438 cubic metres corresponding to a slightly higher average consumption per square metre compared to the previous year of 599 litres (2016: 383,801 m² / 554 l).
