“…The focus of the building's refurbishment was an extreme reduction of its energy consumption to a level where it is possible to cover it with energy supply from local renewable resources on an annual basis [2]. Usually this type of buildings is referred to as "Net Zero Energy Building" or "Plus-Energy Building".…”

“…As the aim of the building concept is that the supply from local renewable resources covers both the energy needed to operate and use the building, the term "Plus-Plus-Energy Building" would be a better fit. The first "Plus-" is put in brackets in order to indicate that the building concept could theoretically achieve the set aim but due to several reasons, which were mostly already discussed in [2], the planned energy saving potential could not be fully realized.…”

“…All other very energy-demanding services needed for scientific purposes ought to be relocated from the offices into the "research"-part of the server room and are thus excluded from the building's boundaries. Only the "office" part of the server room, hosting webservers, file servers and database servers, is included in the boundaries [2,[5][6][7].…”

“…In case of the (Plus-)Plus-Energy Office High-Rise Building, the waste heat is supposed be used as source for heating energy during the winter months [1,7]. As already indicated by the monitoring results in [2], this energy recovery potential could not be fully utilized.…”

Near the center of Vienna one can find the world’s first office tower which was designed to feed more energy into the power grid than is required to operate and use the building. This building is the result of the refurbishment of an over 40 years old high-rise building. The so called “(Plus-)Plus-Energy Office High-Rise Building” offers office space for several institutes of the TU Wien. The building was planned and simulated under the premise that every office occupant uses highly energy-efficient IT-hardware which would result in an average electrical power consumption of approximately 50 Watts per office workplace. Moreover, the cooling system of the building was planned for this case, allowing only for a minimal internal thermal load. To realize the simulation results, conventional office IT-hardware needs to be substituted by energy-efficient one and all intensive computing processes, e.g. simulations, ought to be outsourced into the building’s server room. This research presents the challenges faced during the transition from a conventional scientific office setup to an energy-efficient one. The method which was used to encourage the occupants to participate in this transition process will be discussed and the impact on the building’s energy consumption will be shown.
