120 Inhouse ecology at the Vienna sites The head office sites in Vienna are operated in accordance with the standards of environmental management systems (ISO 14001) (first certification 1998). The revision of ISO 14001 was published in September 2015. Auditing was conducted in accordance with this new version for the first time in 2016. The implementation of environmental measures was bundled through the relocation of the specialized subsidiaries to their new shared “R19” location in 2015, given that operational management of all buildings is performed centrally by ZHS Office- & Facilitymanagement GmbH. This improvement in inhouse ecology for the specialized subsidiaries concerns not only the building itself but also supporting processes, such as purchasing. All these processes are embedded in the environmental management system. The key figures for 2016 contain values for a complete year of operation at this site for the first time. The following measures were implemented in recent years: • Increase in the proportion of energy-efficient office space: One goal is to increase the energy efficiency of the office space. This concerns both the buildings themselves as well as the business and employee commuting to the sites. The “R19” site was constructed in Vienna with these considerations in mind. The building is located right by the express train/subway station, making it ideally connected to the public transportation system. The site consists of five interconnected buildings with a total of 46,000 m2 of lowest-energy office space (Class A – 20 kWh/m2 and year). The air conditioning system – powered by district cooling – is particularly innovative. This reduces CO2 emissions by around 70 percent compared to conventional air conditioning systems. • Use of the server landscape supply infrastructure: An increase in the energy efficiency of the data centers was achieved through the creation of appropriate infrastructure in 2014 as a result of the relocation of components to the new site, which resulted in significant improvements: - Heat recovery: The waste heat produced in a data center by the servers, storage systems, etc. is discharged via heat exchangers installed on the roof. A heat pump is also used in the new data center and uses a portion of this energy for heating/cooling the building. The heat pump is located in the return cooling circuit of the overall cooling system. This is equivalent to a reduction in primary energy use of around 200,000 kWh/year. • - Free cooling: A cooling system consists of a chiller and heat exchangers which extract excess heat from an object. To minimize the runtime of the chiller – and thus to reduce its energy consumption – only outdoor air is used for cooling purposes for as long as possible. The higher the share of free cooling hours, the greater the energy saving due to the non-use of the chillers. Based on the design data, approx. 4,900 hours per year of pure free cooling operation are anticipated. • Energy efficiency: In 2014, the Energy Efficiency Act was enacted in Austria in implementation of the Energy Efficiency Directive 2012/27/EU. The law aims at achieving the 20-20-20 targets by 2020 (i.e. 20 percent fewer greenhouse gases, 20 percent share of renewable energies, and 20 percent more energy efficiency than in 2005). Large companies are therefore required either to have an external energy audit performed every four years as required by the Energy Efficiency Act or to introduce a certified energy and environmental management system. The central institute and the specialized subsidiaries, as well as RBI AG, decided to have an external energy audit. As stipulated in the Act, all majority participations were included. • Fleet and business travel: A new communication tool (“Skype for Business”) was introduced for electronic cooperation and online meetings in 2015. The main goals were to reduce the number of business trips and printed documents. A conscious effort has been underway in recent years to build up a fleet of low-emission vehicles. This has
