This directly applies to over 65 million energy-inefficient buildings in EU27 urban areas as well as heat supply systems. However, unified funding for long-term renovation programs is not planned. To respond quickly to diverse financing options with distinct conditions and target variables, a costly and time-consuming elaboration of detailed renovation projects becomes ineffective.\nThe article outlines the functional algorithm developed for the innovation sandbox, which is intended for the simulation of various renovation\/modernization options in the overall urban heating system including heated buildings, district heating network and heat sources. The aim is crafting the application\/project that meets the specific conditions to the maximum and provides high performance-price ratio. The algorithm is founded on the previously developed methodological concept.\nCreated sandbox\ufffds algorithm:\n\ufffd encompasses the analysis of all components of the overall heating system;\n\ufffd is applicable to the requirements of relevant projects and available funding options;\n\ufffd offers a flexible pre-design assessment of the benefits to be achieved by the project;\n\ufffd capable to consolidate many individual projects;\n\ufffd provides objective and sufficiently precise results for the initial simulation and evaluation of project variations;\n\ufffd does not necessitate specific knowledge in building physics and economics;\n\ufffd utilizes a limited set of input indicators.\nThrough the sandbox, both central and local governments, as well as building owners, can effectively adapt to evolving funding and\/or project tender rules.<\/jats:p>","DOI":"10.5593\/sgem2024\/5.1\/s21.76","type":"proceedings-article","created":{"date-parts":[[2024,12,4]],"date-time":"2024-12-04T12:27:54Z","timestamp":1733315274000},"page":"615-624","source":"Crossref","is-referenced-by-count":1,"title":["SIMULATION OF URBAN HEATING SYSTEMS' RETROFITTING PROJECTS: FROM CONCEPT TO INSTRUMENT"],"prefix":"10.5593","volume":"24","author":[{"given":"Girts","family":"Karnitis","sequence":"first","affiliation":[{"name":"University of Latvia","place":["Latvia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stanislavs","family":"Gendelis","sequence":"additional","affiliation":[{"name":"University of Latvia","place":["Latvia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maris","family":"Pukis","sequence":"additional","affiliation":[{"name":"University of Latvia","place":["Latvia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ugis","family":"Sarma","sequence":"additional","affiliation":[{"name":"University of Latvia","place":["Latvia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edgars","family":"Diebelis","sequence":"additional","affiliation":[{"name":"University of Latvia","place":["Latvia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janis","family":"Bicevskis","sequence":"additional","affiliation":[{"name":"University of Latvia,","place":["Latvia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3602","reference":[{"key":"ref=1","unstructured":"[1] European Council.
