Decarbonization of Heat Supply to Urban Communities, a Regional Approach

Author: Jesús Mª Casado de Pradas. Energy Efficiency Technician in EVE, Ente Vasco de la Energía. Jesús Mª Casado, Energy Efficiency Technician in EVE. Thinking back, 9 years have passed since the publication of the Directive on the energy performance of buildings. Article 6 of that Directive identified the need to analyse the technical, environmental and economic feasibility of alternative installations in new buildings. These include district or block heating, particularly where it is based on energy from renewable sources, as well as Heat Pumps. These premises are included in Law 4/2019 on Energy Sustainability of the Basque Autonomous Community, published on 28 February this year. In effect, with respect to new buildings, provision should be made for [...]

Development schemes for new district heating developments

How can low temperature concepts be applied in new urban developments? The RELaTED Task 2.5 describes a set of guidelines that are, in general terms, based on best practices as most new urban development areas are different in relation to visions, DH network topology, temperature levels, buildings installations, tariff structure, management etc. […]

Prevention of legionella: actions to find safe domestic hot water solutions in relation to district heating

Use of low and ultra-low DH temperatures, that proposes RELaTED project, results in an increase of the energy efficiency of the heating system. However, the low temperatures in general also increase the risk of Legionella. This emphasizes the need of finding safe Legionella solutions for the domestic hot water (DHW) production from district heating (DH). Focus has been on both large installations in multi-family houses and commercial buildings often using a storage tank for hot water, and for smaller installations in one-family houses or in each flat in newer multi-storey houses with instantaneous heating by a heat exchanger. A survey of various challenges and solutions can be found in the IEA Guidebook “Future Low Temperature District Heating Design Guidebook” from [...]

Partners of RELaTED project presented their advances in Ultra-Low Temperature district heating in Copenhaguen

Partners of RELaTED, Renewable Low Temperature District, presented their advances in the innovative concept of decentralized Ultra-Low Temperature (ULT) network solution. The meeting took place at the premises of Danish Technological Institute in Taastrup, Copenhaguen, Denmark, on May 21 - 23. RELaTED Consortium. On the first day of the meeting for Thematic Sessions, several partners visited EnergyFlex House, part of the Danish test facility "Green Lab for Energy Efficient Buildings" (GLEEB) and which interacts with Danish Technological Institute’s other laboratories in a wide cooperation with entrepreneurs, manufacturers, consultants and contractors, as well as national and international knowledge centers. The second day of the meeting and first day of the partners General Assembly was a day-long gathering in which [...]

The innovative tools of RELaTED project were presented at EUSEW 2019

The innovative tools and solutions of RELaTED project were presented at the Policy Conference of EUSEW 2019 (18-20 June in Brussels), the biggest European event dedicated to renewables and efficient energy use in Europe. RELaTED project coordinator, Roberto Garay, took part on the conference "The Green Revolution starts at home" (Thursday 20 June 11.00 - 12.30), organizaed by the Decarb Heat Initiative. This policy session gave a thorough overview of the heating and cooling sector in Europe with its opportunities, tools and technologies available for local, regional and national authorities. Organised by the European Commission and EASME, EU Sustainable Energy Week (EUSEW) is among the biggest events dedicated to renewables and efficient energy use in Europe. In its 14th year, [...]

Definitions of ultra-low temperature district heating

District heating companies, equipment manufacturers, consultants and researchers have discussed definitions of district heating and cooling in general, and also ultra-low temperature district heating. This inform explains the different definitions and most used terms to give the reader not familiar with district heating the background of this system and the technology options. DOWNLOAD THIS DOCUMENT >> Photo by Pixabay from Pexels In the report "Benchmark for performance levels" (C. H. Christiansen, N. Winther, Ecoheat Cities WP2-report, 2012), the following indicative temperature levels and definitions were specified: DH High Temperature System (HT), 100/50 °C DH Low Temperature System (LT), 80/40 °C DH Very Low Temperature System (VLT), 60/30 °C DH Ultra Low Temperature System (ULT), 45/30 °C District cooling [...]

RELaTED concept was presented at the District Heating Road Show, in Poland

District Heating Road Show, Warsaw & South West part of Poland is one of the most relevant events about district heating in Poland. The major outcome of this road show is the heating/cooling knowledge and technology transfer from Denmark to Poland, contributing to the Danish export increase in the district heating market. Photo by Skitterphoto from Pexels On April 1, the Danish Embassy organized a seminar presenting Danish experience in the field of construction of energy-efficient district heating. About 30 people took part, including an expert of the Mazovia Energy Agency (MAE), who informed the audience about the RELaTED Project.

VIDEO: Aventa develops an innovative solar collector system for district heating

Michaela Meir, R&D manager from Aventa and leader of work package 3 in RELaTED project, explains at this video the solution that this Norwegian company is developing in this project. Both the Spanish company IMAR and Aventa are developing solar collector systems for heating. Aventa’s innovation in RELaTED is that these collector systems are decentralized at the end-user side using the district heating network as storage. The final aim is to install the developed technologies at the RELaTED demo sites. Aventa has developed and produced an all-polymeric solar collector of modular design and flexible in dimensions for building integration. Aventa has pioneer in the delivery of solar thermal collectors fully constructed in polymeric structured sheets. Due to mass production processes [...]
