Improving the efficiency of HVAC systems in these buildings is therefore crucial for the energy transition and decarbonisation of cities in the EU.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.itaca.upv.es\/wp-content\/uploads\/2024\/01\/logo-AIGUAterm_v3_ok-1-1024x589.jpg\" alt=\"\" class=\"wp-image-13200\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The main objective of the AIGUAterm project is to analyse the technical and economic feasibility of using secondary water networks with heat pumps and to study the impact of their implementation in the city of Valencia&#8217;s secondary low-pressure network, developing an integral plan for the implementation of this thermal use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To achieve these objectives, the AIGUAterm project will first evaluate the efficiency and feasibility of this solution through a pilot installation at the Universitat Polit\u00e8cnica de Val\u00e8ncia (UPV). This installation will provide real data on the operation of the system, allowing to address the technical challenges of the proposed solution and compare it with traditional air conditioning systems in the same building.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project starts in November 2023 and runs for 27 months, with the participation of two research groups from the Universitat Polit\u00e8cnica de Val\u00e8ncia: the Information and Communication Technologies Against Climate Change (ICTvsCC) group and the Water Technology Institute (ITA). The consortium is completed by the Instituto Tecnol\u00f3gico de la Energ\u00eda (ITE), Geminis Tools and EMIVASA.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AIGUAterm is a project co-funded by the Ag\u00e8ncia Valenciana de la Innovaci\u00f3 (AVI) and the European Union through the European Regional Development Fund (ERDF) Operational Programme for the Valencian Community 2021-2027 (INNEST\/2023\/412).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.itaca.upv.es\/wp-content\/uploads\/2024\/01\/Foto-Piloto_1-1024x692.jpg\" alt=\"\" class=\"wp-image-16128\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Main project results<\/strong> (<em>update March 2026<\/em>)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The project has achieved the following results. An experimental demonstrator has been designed, implemented, and monitored at the Industrial Engineering Building (5N) on the Vera campus of the Universitat Polit\u00e8cnica de Val\u00e8ncia. In this pilot, the technology has been validated under real conditions, achieving <strong>COP values of 4-6<\/strong>, confirming the feasibility of thermal energy recovery from the network.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore, it has been verified that the system has <strong>a nearly negligible impact on the network<\/strong>, with no effects on its hydraulic operation or water quality, which maintains similar properties between the well head and the storage tanks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another relevant outcome is the development of a <strong>thermo-hydraulic model<\/strong> for EPANET, which incorporates temperature as a variable into conventional hydraulic analysis, enabling simulation of the network\u2019s thermal behavior and assessment of the impact of building connections.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, <strong>an urban planning tool<\/strong> has been developed and implemented to identify buildings with the highest energy recovery potential. In the case of the city of Val\u00e8ncia, <strong>315 public buildings<\/strong> have been identified for the implementation of the Aiguaterm solution. As an example, the study conducted at the <strong>Ayora Palace<\/strong> shows that the system can cover <strong>around 90% of the building\u2019s energy demand<\/strong>, achieving <strong>a 55% reduction in electricity consumption<\/strong> due to its higher efficiency.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\"
