An innovative solar system will soon be installed in a building complex in Spain

The solar collectors from Inaventa Solar will deliver energy for heating and domestic hot water to a building complex in Spain, owned by the Basque Government. This campus area is defined as a demonstration site within the Horizon 2020 project RELaTED, where the possibilities of ultra-low temperature district heating systems in corporate building complexes are being tested. Editor’s Note: This article was previously published at Inaventa Solar website. Photo: Inaventa Solar. A new solar system is on its way from the factory of the Norwegian manufacturer of solar collectors  Inaventa Solar at Jevnaker to Iurreta in northern Spain. The solar collectors will be installed as a building-integrated solution in one of the south-facing facades of a larger building [...]

Energy improvement districts in the Basque Country

The RELaTED project deploys a decentralised, Ultra-Low Temperature district heating network concept. In RELaTED, every single building is converted into an energy node, where bi-directional heat exchange is allowed between the network and the building. One of the pilots of the project is located in Iurreta, in the Basque Country (Spain). This demonstration site will showcase the viability of the technology and the feasibility of DH, even in southern Europe. AUTHORS: Jesús M. Casado and José R. López - Ente Vascode la Energía - international@eve.eus District Heating (DH) systems are one of the most energy-efficient heating systems in urban environments, with proven reliability. When combined with renewable and waste heat sources, DH becomes an even higher efficient solution to decarbonise [...]

The Spring Edition of the FEDARENE Info includes information on RELaTED project

The 2021 Spring Edition of the FEDARENE Info is out. This edition -focuses on District Heating and Cooling- includes information about the RELaTED project and the progress made on its concept. Heating and cooling drive half of the energy consumption in Europe. However, more than two-thirds of demand is met with fossil fuels. Changing the conventional fossil paradigm in heating and cooling is essential for reaching the EU decarbonisation goals. District heating is one of the most promising options to decarbonise the heating sector and urban environments in general and is therefore crucial to reach European and global climate goals. Yet, several EU Countries are still facing challenges in implementing this technology: old and inefficient infrastructure, the unreliability of supply, loss of consumers, etc. [...]

Two approaches; one happy district heating & cooling network in Tartu, Estonia

Heat production technologies for district heating are only as efficient as the network they serve. Even if a heat plant is operating at 100% efficiency, heat loss due to the poor thermal insulation of buildings will create an “efficiency” ceiling that improvements at the heat production level cannot overcome. It would be as if a person were trying to heat their home in the winter with all the windows open. This analogy highlights one the biggest challenges for transitioning to ultra-low temperature district heating1 (ULTDH); How can a district heating (DH) operator improve the thermal efficiency for buildings they do not own? AUTHOR: Richard Karl Henahan – Research Analyst at the Institute of Baltic Studies. For the RELaTED project, the [...]

The desing of Triple Function Substations in combination with RELaTED technologies

Ultra-Low temperature district heating introduces multiple benefits at network level, as the reduction of heat losses and the improvement of heat generation efficiency. ULTDH also facilitates the integration of low temperatures renewable energy sources and waste heat into the district heating network. Renewable heat sources as solar thermal and heat pumps can be coupled to the district heating network and the buildings through specially designed district heating substations. Some images of the Microbooster and BILTST demonstration in Taastrup, Denmark. During the development of the RELaTED project, several Triple Function Substations (3FS) have been evaluated and designed. Those were investigated in different versions, connection schemes configurations and operating modes depending on the district heating characteristics, the building types and [...]

EnergyFlexHouse – Energy Neutral Concept House to Test Solar Collectors and District Heating

Editor's Note: This article was previously published at Inaventa Solar website. Photo: DTI Denmark is set on becoming 100% independent of fossil fuels. This is an inspiring challenge, which can be met through development and beneficial application of energy efficient and sustainable technologies, expresses Danish Technological Institute (DTI) on their webpages. DTI is the responsible developer of the energy neutral concept house EnergyFlexHouse, which is a part of “Green Lab for Energy Efficient Buildings” (GLEEB).  This has been established to evaluate and verify innovative solutions, with respect to both energy efficiency cost effective technologies and intelligent interfaces between the users, the equipment and the building itself.  The last piece of this puzzle is the installation of Inaventa Solar’s solar collectors. These are [...]

The RELaTED exploitation seminar shows that with ultra-low temperature district heating, everyone wins

Author: Richard Karl Henahan – Research Analyst at the Institute of Baltic Studies. Richard Karl Henahan – Research Analyst at the Institute of Baltic Studies. Last April, RELaTED partners took part in a three-day virtual exploitation seminar to formulate their individual exploitation plans. Exploitation plans help project beneficiaries develop a strategy and concrete actions for the protection, dissemination, and exploitation of the project results. At the end of the seminar, project partners created their own “Key Exploitable Results” tables which maps how the RELaTED results can be incorporated into their individual business plans. Exploitation plans help project beneficiaries develop a strategy and concrete actions for the protection, dissemination, and exploitation of the project results. Despite the technical and [...]
