Ecological responsibility

While impact on the environment may be minimised when constructing or operating real estate, it cannot be eliminated completely. While efforts to minimise environmental pollution as a rule lead to higher production costs, they are usually more than only compensated for in the medium to long term owing to lower operating and maintenance expenses and a longer life expectancy. When taking into consideration the entire life of a building, it shows that projects that are planned and realised sensitive to the ecology and easy on the environment can be considered profitable in the long term and by all means consistent with economic interests.

At Allreal, development, planning and realisation of all projects are therefore based on the principle of careful use of resources and minimum disruption of the environment. The company thus ensures to consistently comply with all provisions of environmental law, careful use of non-renewable sources of energy and implementation of energy-saving measures during realisation and operation of real estate. As a consequence, projects for third parties, for the sale to third parties and for the company’s own portfolio are balanced both in terms of ecology and the economy.

In this connection, Allreal has made a name for itself as a pioneer and pathbreaker in the development, planning and implementation of ecologically exemplary projects. The company has realised about 100 Minergie buildings since the year 2000, including the zero-heating-energy Eulachhof complex in Winterthur, which was granted the Swiss Solar Award and the Watt d’Or Award. Moreover, Allreal implemented Switzerland’s first building complex – Richti Wallisellen – which complies with the requirements of the 2000-watt society and in Mönchaltorf one of the first residential complexes in Canton Zurich to comply with the Minergie standard A.

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 2016 financial year, this applies to 18 residential properties at a total market value of CHF 758 million and 37 commercial properties at a total market value of CHF 2536 million (2015: 14 residential / 35 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 72.7 million kilowatt-hours, corresponding to an average consumption per square metre of 104.1 kilowatt-hours (2015: 62.7 million kWh / 110.9 kWh). These values correspond to a CO2 equivalent of in total 19 903 tons or 28.7 kilograms per square metre (2015: 16 830 t / 29.7 kg). The reduction of total energy consumption was due on the one hand to the new properties included in the portfolio and on the other to the refurbishment and modernisation of yield-producing properties.

Water consumption of the surveyed properties amounted to 383 801 cubic metres corresponding to a clearly lower average consumption per square metre compared to the previous year of 554 litres (2015: 373 026 m2 / 657 l).
