Decarbonizing the urban environment has two significant challenges: Increasing electricity demand due to the electrification of space heating and increased renewables share in the electricity supply. The European Commission defines a new grid support mechanism for peak-shaving products in renewed Electricity Market Design. This aims to enable a new market tool to stabilize electric supply and demand. This study examines a grid-integrated thermal storage device's technical feasibility and economic performance to meet net zero building (nZEB) definitions. Alternative scenarios considering current national nZEB targets present energy market options and regulations are compared using the life cycle cost and the global warming potentials over the building lifetime. The results show that better building performance is possible even with a low investment increase of 6.7% compared to minimum building standards based on regulations. This enables older building cases to perform similarly with new building targets for Turkish National nZEB. Building electrification using heat pumps and thermal storage systems gives similar economic performances in the long term when a dynamic electricity tariff is available. Adapting the life cycle approach to decision-making in construction contracts can lead to a 50% decrease in building emissions while staying within the same construction budget. © 2024 Elsevier B.V.

Urban Open Therapy Gardens in EU Cities Mission: Izmir Union Park Proposal
(MDPI, 2023) Ebru Alakavuk; Duygu Cinar Umdu; Alakavuk, Ebru; Cinar Umdu, Duygu
One of the biggest problems of societies living in modern world cities is the stress brought by a fast lifestyle. Stress affects individuals psychologically physically and socially. With the increase in the factors that cause stress the need for places that individuals can use as therapy areas has also increased. Especially in this period when the 2030 100 EU (European Union) Cities Mission is determined it is very important to design urban green spaces where the environmental and social criteria of sustainability are met as places where society can breathe and where the society gets away from stress. In this study based on the experiential quality criteria in outdoor therapy gardens and the results of the evaluations made by experts and users suggestions are made to improve the conditions of Birlik Park located in the Gaziemir district of Izmir one of the cities selected for the 100 EU Cities Mission and to use it as an open space therapy garden.
