Feasibility Study Concludes that Redevelopment of Otto Wagner-Areal Can Be Implemented in Plus-Energy-Standard Compliance
A feasibility study of Plus-Energy Standard districts in the Otto Wagner-Areal — the future home to Central European University (CEU)—includes research by Professor Diana Urge-Vorsatz and Postdoctoral Fellow Souran Chatterjee, both from CEU’s Department of Environmental Sciences and Policy.
The Otto Wagner-Areal, a historic art nouveau architectural site, was examined in terms of its potential to be transformed into a Plus-Energy Standard district while also meeting the stringent requirements of cultural heritage management. CEU’s Campus Development team has already incorporated the major findings of the Plus-Energy-Standard report into its development brief for architectural practices currently tendering for the project.
The report, commissioned by the Austrian Federal Ministry of Climate Action, concludes that the redevelopment of the complete Otto Wagner-Areal can be implemented in Plus-Energy-Standard compliance with the protection of historic monuments using the appropriate knowledge. Final energy demand can be reduced by more than 90% compared to a typical refurbishment under monument protection requirements, whereas primary energy demand can be reduced up to 75%. With a special focus on the use of highly energy-efficient user devices and further optimization of the other areas, the Plus-Energy-Standard could also be achieved when including the user equipment in the energy balances.
Chatterjee and Urge-Vorsatz's contributions to the project entail a lifecycle cost-benefit analysis, co-benefit assessment and life-cycle carbon emission assessment. The project team, under the consortium leadership of Schöberl & Pöll GmbH, included the project partners of Central European University, Institute for Architecture and Design of the Vienna University of Technology, LANG consulting and the OeAD-Wohnraumverwaltungs-GmbH. The Otto Wagner-Areal Plus project was funded by the Austrian Federal Ministry of Climate Action as part of the sixth call of the program “City of the Future”.
