Abstract: Improving the energy performance of historic buildings without damaging its cultural heritage possess several challenges such as cultural, social, economic, and technical. However, the current report of IPCC published in 2018 has shown that immediate mitigation actions are required in order to keep the global temperature within  1.5 degrees. Therefore, energy demand by the buildings even by the historic buildings should be reduced significantly. Hence, this study takes the Otto-Wagner-Areal as a case study to show how historic buildings can contribute to the mitigation of climate change without losing their cultural heritage. Otto-Wagner-Areal offers a unique opportunity to preserve its cultural heritage and simultaneously, set a future-fit standard for the coming hundred years, as well as increase its user comfort and value. The result of the exploratory study shows a clear guideline to establish an economic implementation of the “Historic climate neutral-Quarter for the entire monumental protected Otto-Wagner-Areal”. Due to its unique Art Nouveau jewel, this project will be a pioneering holistic renovation of a historic district into a climate neutral district of historic magnitude.
