This data article supplements the \u201cOverview of EU Building Envelope Energy Requirement for Climate Neutrality\u201d by presenting a detailed dataset on building regulations across all 27 EU member states, with a focus on building envelope efficiency. The data include thermal transmittance limits for windows, walls, floors, and roofs, offering insights into regulatory differences and potential opportunities for harmonization. Information was sourced from the Energy Performance of Buildings Directive (EPBD) database, national reports, and scientific literature to ensure comprehensive coverage. Key aspects of each country\u2019s regulations are summarized in tables, covering both new constructions and renovations. The inclusion of K\u00f6ppen\u2013Geiger climate classifications allows for climate-specific analyses, providing valuable context for researchers, policymakers, and construction professionals. This dataset enables comparative studies, helping to identify best practices and inform policy interventions aimed at enhancing energy efficiency across Europe. It also supports the development of tailored strategies to improve building performance in different environmental conditions, ultimately contributing to the EU\u2019s energy and climate targets.<\/jats:p>","DOI":"10.3390\/data9110127","type":"journal-article","created":{"date-parts":[[2024,11,1]],"date-time":"2024-11-01T04:59:54Z","timestamp":1730437194000},"page":"127","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Thermal Transmittance Limits Dataset for New and Existing Buildings Across EU Regulations"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7271-8586","authenticated-orcid":false,"given":"Paolo Maria","family":"Congedo","sequence":"first","affiliation":[{"name":"Department of Engineering for Innovation, University of Salento, 73100 Lecce, LE, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9553-6382","authenticated-orcid":false,"given":"Cristina","family":"Baglivo","sequence":"additional","affiliation":[{"name":"Department of Engineering for Innovation, University of Salento, 73100 Lecce, LE, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2154-7422","authenticated-orcid":false,"given":"Delia","family":"D\u2019Agostino","sequence":"additional","affiliation":[{"name":"European Commission, Joint Research Centre (JRC), 21027 Ispra, VA, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola Maria","family":"Albanese","sequence":"additional","affiliation":[{"name":"Department of Engineering for Innovation, University of Salento, 73100 Lecce, LE, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"129886","DOI":"10.1016\/j.energy.2023.129886","article-title":"Impact of climate change on the energy performance of building envelopes and implications on energy regulations across Europe","volume":"288","author":"Congedo","year":"2024","journal-title":"Energy"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"113716","DOI":"10.1016\/j.enbuild.2023.113716","article-title":"Towards climate neutrality within the European Union: Assessment of the Energy Performance of Buildings Directive implementation in Member States","volume":"301","author":"Maduta","year":"2023","journal-title":"Energy Build."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"110253","DOI":"10.1016\/j.rser.2020.110253","article-title":"Will climate mitigation ambitions lead to carbon neutrality?
