Feasibility analysis of the Plus-Energy District renovation of CEU's new home in the Otto Wagner area
February 24, 2021
Prof. Diana Urge-Vorsatz and Dr. Souran Chatterjee from the Department of Environmental Sciences and Policy, CEU has participated in a project on the feasibility of Positive Energy Districts in Otto-Wagner-Areal. The final report is published by the Austrian Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation and Technology (BMK).
The findings of the study conclude that the redevelopment of the complete Otto-Wagner-Areal can be implemented in Plus-Energy-Standard in compliance with the protection of historic monuments using the appropriate know-how. 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.
Dr. Souran Chatterjee and Prof. Diana Urge-Vorsatz from the department have contributed to this project by conducting a lifecycle cost-benefit analysis, co-benefit assessment, and life-cycle carbon emission assessment in a project team under the consortium leadership of Schöberl & Pöll GmbH and the project partners Central European University, Institute for Architecture and Design of the Vienna University of Technology, LANG consulting and the OeAD-Wohnraumverwaltungs-GmbH.
