RELaTED partners made great advances in last 6 months

On November 24th, the RELaTED project partners came together online at the RELaTED 7th General Assembly. The meeting, that took place in a virtual format, was a great opportunity to talk about their advances in the RELaTED Ultra-Low Temperature district heating solution and establish the work plan for the following semester. After 6 months of hard work, the RELaTED H2020 funded project latest developments were presented by video meeting at the 7th General Assembly. During this virtual event, the partners presented to the consortium their progress in the different work packages. A lot of advances have been made, especially in the four demo sites where the project is beins tested. In Denmark, for example, the Energy Flex Houses systems has [...]

SMACCs master programme invites the RELaTED Project coordinator to talk about district heating

The coordinator of the RELaTED Project will talk about district heating systems at the SMACCs Master Programme. The University of the Basque Country invites the RELaTED Project coordinator, Roberto Garay, for the second consecutive year, to be part of a seminar organized by the Master Programme in Smart Cities and Communities SMACCs. The seminar will be held from 1st to 4th of December, both included, and it will be a great opportunity for students to learn more about sustainable buildings and solar thermal systems in district heating systems. The programme is designed to educate the next generation of engineers and researchers in Smart Cities and Communities by learning best practice from 4 of Europe’s most prestigious universities (Heriot-Watt University, University [...]

Energy meters in District-Heating Substations for Heat Consumption Characterization and Prediction Using Machine-Learning Techniques

The use of smart energy meters enables the monitoring of large quantity of data related to heat consumption patterns in buildings connected to DH networks. This information can be used to understand the interaction between building and the final users´ without accurate information about building characteristics and occupational rates. In this paper, presented at Beyond 2020 digital event, an intuitive and clarifier data-driven model is presented, which couples heat demand and weather variables. This model enables the disaggregation of Space-Heating & Domestic Hot water demand, characterization of the total heat demand and the forecasting for the next hours. Simulations for 53 building have been carried out, with satisfactory results for most of them, reaching R2 values above 0.9 in some [...]

RELaTED Project presentation at Sustainable Places 2020: new developments on Ultra Low Temperature District Heating networks

The RELaTED project was presented at at Sustainable Places 2020, held as digital event due to the health situation in Europe. Antonio Garrido Marijuan explained the main developments of RELaTED within the Integration of Renewables in DHC for Sustainable Living workshop, held on 28th October 2020. The workshop intended to exchange new ideas, lessons learnt from implementation and proposals about the integration of substantial shares of renewable energy sources in district heating and/or cooling (DHC) systems, in order to share commonly with external colleagues the main concepts on reducing the dependency of DHC on fossil fuels and ultimately leading to a more efficient and sustainable energy system. The presentation of the RELaTED project shared the session with other very interesting [...]

Energy & economic assessment of façade-integrated solar thermal systems combined with ultra-low temperature district-heating

Authors: Roberto Garay, project coordinator of RELaTED and Mikel Lumbreras, researcher at TECNALIA, Basque Research and Technology Alliance (BRTA). This paper, published in the journal Renewable Energy (Volume 159, October 2020, Pages 1000-1014), conducts an energy and economic assessment of District Heating (DH) integrated Solar Thermal (ST) systems. An implementation with building-integrated ST collectors coupled to a Low Temperature District Heating (LTDH) system is studied, with special focus on unglazed collectors. ST heat is exploited in the building through direct use, while excess heat is delivered to the network. A novel control strategy for heat flows in the system is proposed. A meta-analysis of several DH configurations, interconnection schemes and installed ST capacity is performed in three different climates: Sevilla (Spain), [...]

RELaTED project will be present at the 8th edition of Sustainable Places 2020 (SP2020)

The workshop 'Integration of renewable energy technologies in district heating and cooling solutions for sustainable living' will bring RELaTED the opportunity to present and demonstrate the RELaTED ultra-low temperature dictrict heating concept. There is a large potential to integrate substantial shares of renewable energy sources in district heating and/or cooling systems, reducing dependency of DHC on fossil fuels and ultimately leading to a more efficient and sustainable energy system. A number of EU funded projects are currently working on this topic. The objective of the workshop is to share WEDISTRICT project concept with other sister projects and interested stakeholders in order to exchange new ideas, lessons learnt from implementation, proposals about the successful integration of renewable technologies in DHC. Sustainable [...]

Turning waste into energy for Belgrade’s district heating

The ambitious Belgrade Energy-from-Waste project received the IJ Global European Waste deal of the year 2019 award on 20th July 2020. IJGlobal recognize and reward excellent and exceptional performance across all regions, globally. Vinca Landfill Site october 2018. The project, the first of its kind in Serbia, addresses one of the most urgent environmental challenges in Europe updating the City's existing waste management practices and enhancing Belgrade's renewable power and heat generation capacity. Beo Cista Energija – the joint-venture formed by Suez, Itochu Corporation and Marguerite entered into a 25-year Public-Pivate Partnership with the City of Belgrade to deliver modern waste management infrastructure for its 1.7 million population. The project is intended to closure the existing landfill at [...]

“The global crisis of COVID-19 has highlighted the importance of the sustainable Energy Transition”

Author: Olga Macías, Smart Buildings and Cities Researcher at TECNALIA Research and Innovation. The last few months all the news has been overshadowed by the global crisis of COVID-19. This pandemic has turned the whole world upside down and shaken worldwide economies. Among other consequences, many of us agree that this crisis has highlighted the importance of the sustainable Energy Transition, and the need to search for solutions with technical and economic feasibility that will facilitate this transition. That is why, now more than ever, we believe in the concept of ultra-low temperature, de-carbonized and smart networks developed in the RELaTED project as a solution that allows transforming the current district networks with a greater use of renewable [...]
