Energy flexibility and District Heating Control

The activities carried out under the RELaTED project address the need for increased energy efficiency and new management strategies in relation to ULT DH. Installing smart meters allows for increased insight into the conditions of networks and installations and by the use of machine learning to utilize these data in new algorithms and tools. RELaTED report 2.4, which is part of a set of reports that define the system architecture of the RELaTED concept, describes new possibilities concerning measurement and control of ULT DH and other DH systems with high energy flexibility. RELaTED task 2.4 aims at developing a framework for advanced control procedures for managing and optimizing ULT DH networks based on energy consumers equipped with smart meters and [...]

Tecnalia presented the benefits of the RELaTED district heating concept at the Building Simulation 2019 Rome

The RELaTED concept was presented at the 16th IBPSA Conference Building Simulation 2019 Rome. Mikel Lumbreras, researcher at Tecnalia, presented the study “Simulation of Unglazed Solar Thermal Integrated into Façade & Combined with Ultra Low Temperature District Heating”. This session was a great opportunity to share information about the RELaTED ultra low district heating concept and to show the benefits of this system in combination with the unglazed solar thermal system. Building Simulation 2019 Rome took place in Rome, on September 2-4, and was organized by the International Building Performance Simulation Association, a non-profit international society of building performance simulation researchers, software developers, and practitioners, founded to advance and promote the science of building performance simulation in order to improve [...]

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 [...]
