NEGST – NEW GENERATION OF SOLAR THERMAL SYSTEMS – is a project financed by the European Commission

Nästa generation av solvärmesystem Solvärmesystem kan bidra till att bevara vår natur och dess tillgångar. För att få en ökad spridning av solvärmesystem så krävs en fortsatt utveckling och optimering av produkterna fastän de redan idag är välutvecklade. För att kollektivt kunna möta denna utmaning på Europeisk bas så initierades projektet NEGST av Institutionen för Termodynamik och Värmeteknik (ITW) på Stuttgarts Universitet tillsammans med företaget “Solar- und Wärmetechnik Stuttgart” (SWT). Projektet ”NEGST“ (New Generation of Solar Thermal Systems) syftar huvudsakligen till utveckling och marknadsintroduktion av kostnadseffektiva solvärmesystem. Denna ”nya” generation av solvärmesystem representerar en ytterligare utveckling av dagens systemteknik med avseende på förbättringar av prestanda och minskning av investeringskostnad. I projektet behandlas både solvärmda tappvarmvattensystem och kombisystem (system för kombinerad tappvattenberedning och uppvärmning) samt system för sol-kylning och system för avsaltning av havsvatten. Projektet är huvudsakligen finansierat från den Europiska Kommissionen och har en budget på 1,3 miljoner Euro och kommer att pågå i tre år. Det finansiella bidraget från den europiska kommissionen intygar betydelsen av solvärmeteknik i Europa. Eftersom 18 olika institutioner från vetenskap, forskning och industri från 14 olika länder deltar i projektet garanteras att de mest betydelsefulla Europeiska systemkraven beaktas. Följaktligen skapas den plattform för en enhetlig europeisk marknad som krävs för en fortsatt marknadstillväxt. Från Sverige deltar SP Sveriges Provnings- och Forskningsinstitut och SERC från Högskolan i Dalarna.

NEGST – NEW GENERATION OF SOLAR THERMAL SYSTEMS – Progetto finanziato dalla Comunità

La futura generazione dei sistemi solari termici I sistemi solari termici sono in grado di fornire un contributo fondamentale alla salvaguardia dell’ambiente ed al risparmio delle risorse energetiche tradizionali. Tali sistemi si basano su una tecnologia ad uno stadio di piena maturità, tuttavia per la loro ulteriore diffusione è richiesta un’attività continua di sviluppo ed ottimizzazione. Per affrontare questa sfida collettivamente, su base europea, è stato avviato il Progetto NEGST, coordinato dall’Istituto di Termodinamica e Termotecnica (ITW) dell’Università di Stoccarda insieme alla Società di Termotecnica ed Energia Solare di Stoccarda (SWT). Il progetto “NEGST” (New Generation of Solar Thermal Systems) punta essenzialmente allo sviluppo ed introduzione nel mercato di sistemi solari termici economicamente competitivi. Questa “nuova” generazione di sistemi si otterrà attraverso il miglioramento delle prestazioni e la riduzione dei costi della tecnologia attuale. Oltre ai tradizionali sistemi solari per la produzione di acqua calda per uso igienico-sanitario (DHW), il progetto prende in considerazione i sistemi combinati (acqua calda sanitaria e riscaldamento ambientale) e gli impianti per il raffrescamento e la dissalazione alimentati da fonte solare. Il progetto, finanziato in misura predominante dalla Comunità Europea, prevede un budget di 1,3 milioni di Euro per una durata di tre anni. Tale contributo finanziario testimonia l’importanza attribuita al solare termico in Europa. Nel progetto sono coinvolte 18 istituzioni, operanti nei settori della ricerca e dell’industria, provenienti da 14 differenti Paesi; ciò garantisce che saranno considerate le esigenze di sviluppo di tutti i principali sistemi utilizzati a livello europeo. In tal modo si creeranno anche i presupposti per un mercato europeo più omogeneo, requisito indispensabile per una sua ulteriore crescita. Ulteriori informazioni sul progetto e sui partecipanti e i riferimenti per eventuali contatti sono disponibili sul sito internet: http://www.swt-technologie.de/html/negst.html.

Η Νέα γενιά Ηλιακών Θερµικών Συστηµάτων Τα ηλιακά θερµικά συστήµατα είναι δυνατό να συνεισφέρουν στην προστασία του περιβάλλοντος, εξοικονοµώντας παράλληλα φυσικούς πόρους. Αν και τα ηλιακά θερµικά συστήµατα βρίσκονται σε ώριµο τεχνολογικό στάδιο, εν τούτοις, περαιτέρω διάδοση της τεχνολογίας αυτής απαιτεί συνεχή ανάπτυξη και βελτιστοποίηση. Στο πλαίσιο αντιµετώπισης, σε κοινό Ευρωπαϊκό επίπεδο, της πρόκλησης αυτής, το Ινστιτούτο Θερµοδυναµικής και Θερµικών Τεχνολογιών (ITW) του Πανεπιστηµίου της Στουτγάρδης, σε συνεργασία µε την εταιρεία “Solar- und Wärmetechnik Stuttgart” (SWT), ανέλαβαν την πρωτοβουλία ανάπτυξης του Προγράµµατος NEGST. To Πρόγραµµα „NEGST“ (New Generation of Solar Thermal Systems/ Νέα Γενιά Ηλιακών Θερµικών Συστηµάτων), στοχεύει κυρίως στην ανάπτυξη και διείσδυση στην αγορά οικονοµικά αποδοτικών ηλιακών συστηµάτων. Η “νέα” αυτή γενιά ηλιακών θερµικών συστηµάτων, εκφράζει την περαιτέρω ανάπτυξη της τεχνολογίας των σηµερινών συστηµάτων, µε γνώµονα την αύξηση της απόδοσης και µείωση του κόστους. Παράλληλα µε τα ηλιακά θερµικά συστήµατα για ζεστό νερό χρήσης, εξετάζονται συστήµατα παράλληλης χρήσης θέρµανσης χώρων, καθώς και συστήµατα ηλιακής ψύξης και ηλιακής αφαλάτωσης. Το Πρόγραµµα, χρηµατοδοτούµενο, ως επί το πλείστον, από την Ευρωπαϊκή Επιτροπή, παρουσιάζει συνολικό προϋπολογισµό της τάξης των 1.3 εκατ. €, και έχει διάρκεια τριών χρόνων. Η οικονοµική συµµετοχή της Ευρωπαϊκής Επιτροπής επιβεβαιώνει την σπουδαιότητα της τεχνολογίας των θερµικών ηλιακών για την Ευρώπη.

NEGST – NEW GENERATION OF SOLAR THERMAL SYSTEMS – est un projet financé par la Commission européenne

La future génération de systèmes solaires thermiques. Les systèmes solaires thermiques peuvent contribuer à la protection de l’environnement et sauvegarder nos ressources naturelles. Bien que les systèmes solaires thermiques soient bien développés à l’heure actuelle, une diffusion plus poussée de cette technologie demande un développement et une optimisation continue. Afin de relever ce défi collectivement en Europe, le projet NEGST a été initié par l’Institut pour la thermodynamique et la Chaleur (Institut für Thermodynamik und Wärmetechnik, ITW), l’Université de Stuttgart et la compagnie Solaire et Thermodynamique de Stuttgart (Solar- und Wärmetechnik Stuttgart, SWT). Le projet NEGST (Nouvelle Génération de Systèmes Thermiques Solaires) vise principalement le développement et l’introduction de systèmes solaires à coût réduit. Cette nouvelle génération de systèmes thermiques solaires représente un développement de la technologie tenant compte de l’amélioration des performances et de la réduction des coûts du système. En plus des systèmes pour la préparation de l’eau chaude sanitaire (ECS), cette étude prend en compte les systèmes solaires combinés (ECS + chauffage), les systèmes pour la désalinisation de l’eau de mer et la climatisation solaire. Ce projet, principalement financé par la Commission européenne, a un budget de 1,3 millions d’euros et a une durée de 3 ans. La contribution financière de la Commission européenne témoigne de la pertinence de la technologie du solaire thermique en Europe. La prise en compte des besoins européens est garantie par la présence de 18 établissements différents de recherche scientifique et industrielle, répartis sur 14 pays. On pourra créer ainsi de bonnes bases pour le développement du solaire thermique dans le contexte du marché unique européen.

1. Communiqué de presse

Septembre 2004

NEGST – NEW GENERATION OF SOLAR THERMAL SYSTEMS – is een door de EU gefinancierd project

‘WHAT’S NEGST?’ EEN VOLGENDE GENERATIE ZONTHERMISCHE SYSTEMEN Zonthermische systemen leveren een positieve bijdrage aan het milieu, onder andere door de energiebesparing die ze opleveren. Hierdoor worden natuurlijke hulpbronnen minder snel uitgeput en CO2-uitstoot wordt teruggedrongen. Hoewel de huidige zonthermische systemen qua ontwikkeling volwassen zijn, vereist de verspreiding hiervan nog verdere ontwikkeling en optimalisering. Daarnaast kan de technologie verder worden uitgewerkt in nieuwe concepten en systemen. Om deze uitdaging collectief in Europees verband te kunnen realiseren is het Europese “NEGST”-project opgestart. Het initiatief voor het opzetten van dit project is genomen door het Duitse “Institut für Thermodynamik und Wärmetechnik” (ITW), samen met het bedrijf “Solar- und Wärmetechnik Stuttgart” (SWT). Nederland is in dit project vertegenwoordigd door TNO en Ecofys. Het project “NEGST” (New Generation of Solar Thermal Systems – Nieuwe Generatie Zonthermische systemen) richt zich voornamelijk op de ontwikkeling en marktintroductie van nieuwe kosteneffectieve zonthermische systemen. Deze “nieuwe” generatie systemen heeft de huidige systeemtechnologie als basis en is gericht op een verdere prestatieverbetering en kostenreductie. Behalve zonne-energiesystemen voor de productie van warm tapwater, worden in het NEGST-project ook zonnecombisystemen (zonne-energie voor zowel tapwater als ruimteverwarming), zongedreven koeling, zongedreven warmtepompen en het ontzouten van zeewater met behulp van de zon beschouwd. Het NEGST project is voor een belangrijk deel gefinancierd door de EU. Het totale budget is 1,3 miljoen euro en het project duurt drie jaar. Hiermee onderschrijft de EU het belang dat zij hecht aan zonthermische technologie in Europa. Ieder land heeft zo zijn eigen wensen voor wat betreft ontwikkeling van concepten en systemen. Deze kunnen worden verwezenlijkt doordat in dit project 18 onderzoeksinstellingen en industriepartners uit 14 verschillende Europese landen zijn vertegenwoordigd. Hiermee wordt een basis gelegd voor een uniforme Europese markt, die een verdere marktgroei van zonthermische systemen in Europa bevordert.

ANDIDATES FOR NEW GENERATION OF SYSTEMS WANTED P 1 – NEXT GENERATION OF SYSTEMS

ndustry and researchers shall join forces to accelerate the development of thermal solar system echnology. Enterprises active in the field of solar thermal system design may profit from gathered uropean expertise in system development, testing and evaluation. NEGST offers a unique pportunity to present and develop your next generation of systems. The steps planned in WP1 to esign, build and evaluate the next generation of systems are: . identify promising system concepts for a next generation of systems . theoretically evaluate the candidates presented in step one . advise industry to design and build the systems . field evaluate system operation

f you are a designer of active solar thermal systems you are now asked to suggest your view of he next generation of systems. Contact your preferred participant or SPF (see last page of this ewsletter) and mention if confidentiality is desired. This is a unique opportunity to link up with he experts who will help you evaluate your ideas and develop them into a product.


SURVEY WP 2 – STANDARDISED SYSTEM CONCEPTS NEGST WP2 “ Standardised System Concepts” has the goal to overcome the still existing barriers that hinder the dissemination of larger solar systems to become standard in hot water supply (and heating) for multi family houses and other buildings with a large hot water demand.

First step in this work package: By means of a questionnaire a survey of the practice of designing, planning, installing and marketing larger solar systems in different European countries will be performed in autumn 2004. This questionnaire will be sent out by end of the year 2004. Main target groups: Building industry, Solar manufacturers, Planners & Installers.

Topics to be dealt within this questionnaire: Costs, district heating, decentralisation, subsidies, quality of products and installation, training of installers, building laws, financing, yields, performance, monitoring devices, monitoring data, hydraulic schemes, dimensioning,….

Besides further steps in this work package, this survey will already contribute to the final result which is a comprehensive but very practical guideline for realisation of large solar systems covering all aspects from financing to technical issues, design, installation, maintenance and marketing. To make them well known series of workshops will be performed to intensively distribute them amongst the target groups. CALL FOR INPUT FROM INDUSTRY WP 4 - TOWARDS THE NEXT GENERATION OF STANDARDS As solar thermal components, systems and applications are developing, new standards are and will be needed. Standards will always – by nature – be developed with a certain time delay compared with developments of products and systems. This delay is a barrier for the new products to enter the market, as no testing and certification is possible or existing standards do not express the benefits of the new products. The mission of this work is to minimize this time delay in order to bring the new and better products on the market as fast as possible.

The NEGST WP4 group has identified some areas where new/updated standards are/will be needed: • advanced/new types of collectors • advanced/new types of stores • advanced/new types of controllers • combisystems (DHW/SH) • solar cooling • combination of solar thermal and heat pump technology • solar desalination • fluids • LCA (environmental Life Cycle Assessment) • conversion from m² to power and energy (for use in market statistics) • building integration

This list is not the final or complete list - decision on the specific topics to be treated in the project will be taken during the first half year of the project (before the end of 2004), and then before the end of 2005 decision will be taken on the specific proposals to be passed on to CEN TC312.

The group now calls for inputs from industry and others on specific products, systems, applications, topics, etc., for which new or updated standards are needed. Please give your input to Jan Erik Nielsen, ESTIF by mail ([email protected]) as soon as possible.

This is done by close collaboration with industry active in the field of solar thermal systems. For that purpose a detailed survey on today’s state of the art system technology has been made and new system concepts have been evaluated. Industry and researchers have been asked to contribute their ideas and to present their next generation of systems.

The market survey on today’s system technology identifies differences in technology which are relevant in the different countries today and which may be important tomorrow. Besides it gives an overview on different market requirements, shows the distribution of solar domestic hot

water and combisystems, indicates the share of installed collector area in single and multifamily houses, and includes the space heating and domestic hot water demand in the individual countries. An extract of the survey results is given in figure 1 and figure 2. Figure 1 shows the typically installed power capacity per solar domestic hot water system (SDHW) in comparison with the solar fraction in the respective countries.

Figure 1: Typically installed power capacity and solar fraction per SDHW Figure 2 shows the share of glazed solar collectors within combisystems installed in single family houses, multifamily houses and other applications for each country.

Meanwhile the systems were grouped in system classes with similarities and the most promising system types of these classes with the highest impact on the market have been identified. In the next step the selected system types will be further evaluated on site. Finally the systems will be presented with regard to efficiency, ecological and installation aspects as well as costs.

All collected experiences will be used to compile design and installation guidelines for the new system generation and will be made available for industry. Workshops with industry participants will be arranged in order to discuss the results and to derive general recommendations for future system development. Dates and places of workshops are listed on page 4.



SELECTED RESULTS OF WORK PACKAGE 2 The work in NEGST WP2 is meant to point out and overcome the barriers that hinder the dissemination of large solar thermal systems for the hot water supply in large buildings. While there is already a wide product range of standardised products offered by the industry for solar hot water preparation systems and also in combination with space heating, standardised solar systems for multi family houses and hotels are not available up to now in most European countries.

As a step towards a higher level of standardisation and systematic approach for large systems, a detailed questionnaire for planners, solar manufacturers, and the building industry was developed within the NEGST project and sent out to a clearly defined target group. The aim is to get feedback about the experiences and major barriers for the implementation of large solar thermal systems. The results of the evaluation of the questionnaires will be made available on the project website in August 2005.

SELECTED RESULTS OF WORK PACKAGE 3 In this work package pre-normative work on uniform methodologies to fully integrate solar heating systems in the building envelope is done. For this reason, an inventory of existing requirements and directives in EU countries has been compiled concerning topics like strength of construction (wind/snow), avoidance of fire risk, noise problems, construction damage, air leakages/thermal bridges, environmentally problematical materials, rain and moisture penetration, water tightness and maintenance of the roof. This inventory includes more than 150 regulations, guidelines and national standards concerning building integration from Austria, France, Germany, The Netherlands, Norway, Portugal and Sweden.

This work package has the objective to complete pre-normative work for a next generation of solar thermal systems and components. These new standards are needed to help new and better products, which are not covered by the existing standards, to penetrate the market as soon as possible. One of the results in work package 4 is the “conversion from m² to Wth”. Traditionally solar thermal installations have been accounted in square meters of collector area, a unit not comparable with other energy sources counting their capacity in kW. Therefore a formula was developed to convert installed collector area into installed solar thermal capacity counted in kW:

P = 0.7 kW/m² * A, P in [kW], A in [m²]

The comparison of global installed solar thermal capacity with the regenerative energy sources photovoltaics and wind power is illustrated in figure 3.

Figure 3: Comparison of different energy sources

SELECTED RESULTS OF WORK PACKAGE 5 The main objective of NEGST Work Package 5 is to assess the potential of solar thermal systems for advanced applications, such as cooling and desalination.

In this context, an overview on all cooling and desalination systems which can be suitable coupled with low to medium temperature solar collectors constitutes a preliminary step towards the aforesaid objective. Thus, the first step of this work package is an investigation, relevant to each considered process, which main issues concern: the brief description of the technologies under investigation, the assessment of the global energy requirements, costs, the main



advantages and drawbacks in particular in view of the coupling with solar thermal systems, the development status and their possible commercial diffusion. The result of this investigation is a “Technical Status Report on solar cooling and solar desalination”. This report will be available via the project website in July 2005 (http://www.swt-technologie.de/html/wp5.html). Besides information about the gerenal status of solar cooling and solar desalination the purpose of the report is to support in the selection of dedicated solar cooling or desalination systems worth to be subject to a further analysis in the following steps of the NEGST WP5. For this purpose, a preliminary screening criterion is introduced according to an energy saving approach. The obtained results are then to be analysed considering the system capital cost, the level of commercial maturity, the presence of technological barriers and any other key factor in order to reach a final assessment of the most promising solar thermal systems for cooling and desalination.

WORKSHOPS WITH INDUSTRY PARTICIPANTS National workshops with industry participants will be arranged in order to disseminate the current project results among a large number of national experts. Besides pure knowledge transfer the intention of these workshops is to initiate a discussion within solar industry in order to motivate them to intensify their efforts in the development of the next generation of solar thermal systems.

NEGST – NEW GENERATION OF SOLAR THERMAL SYSTEMS projecto financiado pela Comissão Europeia, na DGTREN, no âmbito do 6ºPQ

ALGUNS RESULTADOS DO WP 1 O WP 1 tem por objectivo o desenvolvimento de uma nova geração de sistemas solares térmicos e a sua introdução no mercado. Este trabalho conta com a colaboração da indústria activa no campo dos sistemas solares térmicos. Para tal foi efectuada uma pesquisa detalhada do actual estado da arte na tecnologia dos sistemas e novos conceitos de sistemas foram avaliados. Foi solicitado à indústria e aos investigadores que contribuíssem com as suas ideias e apresentassem os seus sistemas de nova geração. A pesquisa de mercado sobre a tecnologia actual dos sistemas solares identifica diferenças nas abordagens tecnológicas tomadas pelos diferentes países e que podem ser importantes futuramente. Além disso oferece uma visão acerca dos diferentes requisitos dos mercados, da distribuição de sistemas solares para aquecimento de águas sanitárias e sistemas combinados, indicando a quantidade e área de colectores instalados em habitações

unifamiliares e multifamiliares e inclui as necessidades de aquecimento ambiente e aquecimento de águas sanitárias nos diferentes países. Nas figuras 1 e 2 está representado um resumo dos resultados da pesquisa efectuada. A figura 1 mostra a capacidade típica de potência instalada por sistemas solares de aquecimento de água em comparação com a fracção solar nos respectivos países.

Figure 1: Capacidade de potência instalada e fracção solar por sistema de AQS A figura 2 mostra a quantidade de colectores solares com cobertura, integrados em sistemas combinados e instalados em habitações unifamiliares, multifamiliares e outras aplicações, para cada país.

Os sistemas solares foram agrupados em classes de sistemas com semelhanças e os tipos de sistemas mais promissores destas classes, com maior impacto no mercado, foram identificados. Num próximo passo os tipos de sistemas seleccionados serão avaliados localmente. Finalmente os sistemas serão apresentados em relação ao comportamento térmico, aspectos ecológicos e de instalação bem como aspectos de custo.

Figure 2: Distruibuição da instalação de colectores solares com cobertura em sistemas combinados em 2003/04. Todos os resultados das experiências serão utilizados para compilar guias de concepção e instalação para a nova geração de sistemas solares que serão disponibilizados à indústria. Serão também promovidos Workshops com participantes da indústria com vista à discussão de resultados e recomendações para o futuro desenvolvimento de sistemas. As datas e locais dos Workshops encontram-se indicados na página 4.



ALGUNS RESULTADOS DO WP 2 O trabalho desenvolvido no WP 2 consiste em identificar e ultrapassar as barreiras que impedem a divulgação dos sistemas solares térmicos de grande dimensão para fornecimento de água quente em grandes edifícios. Enquanto que, actualmente, já se encontra uma vasta gama de sistemas solares standarizados oferecidos pela indústria para aquecimento de águas sanitárias e também sistemas combinados para aquecimento ambiente, não estão ainda disponíveis sistemas standarizados para habitações multifamiliares e hotéis, na maioria dos países europeus. Como um passo em direcção a um maior nível de standarização e aproximação sistemática para sistemas solares térmicos de grande dimensão, foi solicitado o preenchimento de um questionário detalhado a projectistas, fabricantes e construtores civis no âmbito do projecto NEGST, tendo sido os mesmos enviados a um grupo alvo definido. O objectivo do preenchimento destes questionários é obter algum feedback acerca de experiências e barreiras que impedem a implementação de sistemas solares térmicos de grande dimensão. Os resultados da avaliação destes questionários será disponibilizado no website do projecto em Agosto de 2005. ALGUNS RESULTADOS DO WP 3 Neste WP realiza-se trabalho pré-normativo sobre metodologias uniformes de integração completa de sistemas solares de aquecimento em fachadas de edifícios. Por esta razão foi compilado um inventário de requisitos e directivas existentes nos países da EU considerando itens tais como resistência da construção (vento/neve), áreas de risco, problemas de ruído, danos na construção, fugas de ar/pontes térmicas, materiais ambientalmente problemáticos, penetração de chuva e humidade, impermeabilidade à água e manutenção do telhado. Este inventário inclui mais de 150 regulamentos, regras e normas nacionais relativas à integração dos sistemas solares térmicos em edifícios na Áustria, França, Alemanha, Países Nórdicos, Noruega, Portugal e Suécia. ALGUNS RESULTADOS DO WP4 Este WP tem por objectivo realizar trabalho pré-normativo desenvolvido para a nova geração de sistemas solares térmicos e componentes. O desenvolvimento de novas normas é necessário para a criação de novos e melhores produtos, não contemplados pelas normas actualmente existentes, por forma a introduzi-los no mercado tão breve quanto possível. Um dos resultados neste grupo de trabalho é a “conversão de m² para W th”. Tradicionalmente as instalações de sistemas solares térmicos têm sido contabilizadas em metro quadrado de área de colector, uma unidade não comparável com outras fontes de energia, contabilizadas em kW. Deste modo foi desenvolvida uma fórmula para converter a área de colector instalada em capacidade térmica solar instalada, contabilizada em kW:

P = 0.7 kW/m² * A, P em [kW], A em [m²] Na figura 3 está representada uma comparação entre a capacidade térmica global instalada e a potência proveniente da energia eólica e fotovoltaica.

Figure 3: Comparação de diferentes fontes energéticas.

RESULTADOS DO GRUPO DE TRABALHO 5 O objectivo do WP 5 é estimar o potencial de sistemas solares térmicos para aplicações avançadas, tais como arrefecimento e dessanalização. Neste contexto, uma visão sobre todos os sistemas de arrefecimento e dessanalização que podem adequadamente ser associados a colectores a baixas e médias temperaturas, constitui um passo preliminar para o objectivo supracitado. Deste modo, o primeiro passo deste WP é



uma investigação de cada processo considerado, sendo os temas principais: uma breve descrição das tecnologias em investigação, um levantamento dos consumos gerais de energia, custos, principais vantagens e desvantagens, em particular com vista à associação com sistemas solares térmicos, estado de desenvolvimento e possível difusão comercial. O resultado desta investigação é um “Relatório Técnico sobre o arrefecimento e dessanalização solares”. Este relatório estará disponível no website em Julho de 2005. (http://www.swt-technologie.de/html/wp5.html). Para além de informação genérica sobre arrefecimento e dessalinização solares, é propósito deste relatório dar suporte à selecção de sistemas dedicados ao arrefecimento e dessanalização solares que sejam interessantes para uma análise mais detalhada nos passos seguintes do WP5 do NEGST. Para tal, é introduzido um critério de selecção preliminar de acordo com a possibilidade de poupança de energia. Os resultados obtidos serão analisados considerando o custo do investimento, o nível de maturidade comercial, a presença de barreiras tecnológicas e qualquer outro factor chave com vista a alcançar um levantamento final das melhores opções para a utilização de sistemas solares térmicos no arrefecimento e na dessanalização. WORKSHOPS COM PARTICIPANTES DA INSÚSTRIA Serão promovidos workshops nacionais com participantes da indústria com vista à divulgação dos resultados correntes do projecto entre um largo número de especialistas de cada país. Para além da transferência de conhecimentos, pretende-se que nestes Workshops seja iniciada uma discussão que visa conjugar esforços da indústria solar direccionados para o desenvolvimento de uma nova geração de sistemas solares térmicos. Os workshops nacionais terão lugar em: - Dinamarca: Technical University of Denmark, 9 de Novembro 2005

Övergripande syfte med projektet är att tillhandahålla en ram för forskning inriktad på att föra fram mer kostnadseffektiva solvärmesystem, speciellt för tappvarmvattenproduktion och / eller uppvärmning, på marknaden. Dessa är en nödvändigt förutsättning för att EU’s mål om minskade CO2-utsläpp och kostnadseffektiv förnybar energiförsörjning ska kunna bli verklighet. Arbetet är uppdelat i 6 ”paket” eller WP:n. Målsättning för WP1 är utveckling av en ny generation solvärmesystem och deras introduktion på marknaden, medan WP2 sysslar med standardiserade systemkoncept för större solvärmesystem. WP3 ägnas åt byggnadsintegration av solvärme och i WP 4 arbetar vi med att analysera industrins behov och ta fram underlag för framtida standarder för system och komponenter. WP 5 fokuserar på avancerade tillämpningar som avsaltning av havsvatten och kylsystem och WP6 hanterar projektledning och spridning av resultat. Projektdeltagare Genom att sammanföra 18 olika organisationer från provning, forskning och industri ifrån 14 olika länder når vi en heltäckande bild av de viktigaste europeiska systemkraven. På så sätt läggs en grund för den enhetliga europeiska marknad som är en förutsättning för fortsatt stark tillväxt. EU-kommissionens ekonomiska stöd bekräftar betydelsen av solvärmetekniken i Europa. Internet www.swt-technologie.de/html/negst.html Detta nyhetsbrev ges ut regelbundet för att informera industri, tillverkare och andra intresserade om status och resultat från projektet.

Valda resultat från WP1 Målsättning för detta delprojekt är ”utveckling” av en ny generation solvärmesystem och deras introduktion på marknaden. Detta sker genom nära samarbete med industri aktiv inom området solvärmesystem. För detta syfte har en enkätundersökning över dagens status inom systemteknik genomförts och nya systemkoncept har utvärderats. Industri och forskare har ombetts bidra med sina idéer och att presentera sina kommande generationer av system. Marknadsundersökningen om dagens systemteknik identifierar skillnader i teknik som är relevanta i dag och som kan vara viktiga i framtiden. Dessutom ger den en överblick av olika marknadskrav, visar fördelningen mellan tappvatten- och kombisystem, fördelningen mellan installationer i en- och flerfamiljshus och ger en bild av varmvatten- och uppvärmningsbehov i de olika länderna. Figur 1 och 2 visar utdrag från undersökningen. Figur 1 visar typisk installerad effektkapacitet per tappvattensystem och typiska täckningsgrader i de olika länderna.

Fig.1 Typisk installerad effekt och täckningsgrad i små tappvattensystem i några olika länder.

Figur 2 visar andelen glasade solfångare i kombisystem i de olika tillämpningarna enfamiljshus, flerfamiljshus samt andra tillämpningar i olika länder. Dessutom har systemkoncept delats in i grupper och de mest lovande typerna, med de största marknadsgenomslagen, har identifierats. I nästa steg kommer de utvalda systemtyperna att

2006-03-20 3(4)

utvärderas vidare under drift. Slutligen kommer dessa system att presenteras med avseende på effektivitet, ekologi- och installationsaspekter samt kostnader. All samlad erfarenhet kommer att sammanställas i design- och installationsvägledningar för en ny systemgeneration och göras tillgängliga för industrin. Industriworkshops kommer att ordnas för att diskutera resultaten och ta fram råd för framtida systemutveckling. Tider o platser för dessa workshops listas på sidan 4. Valda resultat från WP2 Arbetet i WP2 är tänkt att identifiera och överbrygga barriärer som ligger i vägen för ökad spridning av solvärmda tappvarmvattensystem i större byggnader. I motsats till situationen för småsystem, där standardiserade produkter för både tappvatten- och kombisystem tillhandahålls av industrin, finns det i de flesta europeiska länder inga standardiserade koncept för t.ex. flerfamiljshus och hotell. Som ett steg mot en högre grad av standardisering och systematiskt tillvägagångssätt för stora system har ett frågeformulär tagits fram och distribuerats till konsulter, solvärmeindustri och byggbransch i de olika deltagarländerna. Målet med enkäten var att samla in erfarenheter av och identifiera hinder för introduktionen av stora solvärmesystem. Resultaten från enkätundersökningen kommer att finnas tillgängliga på projekt hemsidan inom kort. Valda resultat från WP3 I detta delprojekt arbetar man med att ta fram generell metodik för en fullständig integration av solvärmesystem i byggnadsskalet. Av detta skäl har man gjort en sammanställning av gällande regler och förordningar inom EU inom områdena lasttålighet, brandsäkerhet, ljudproblem, lufttäthet och köldbryggor, miljömässigt tveksamma material, regn- och fuktinträngning och takunderhåll. Inventeringen omfattar mer än 150 regler, föreskrifter och standarder angående byggnadsintegration från Österrike, Frankrike, Holland, Norge, Portugal och Sverige. Valda resultat från WP4 WP4 har som målsättning att färdigställa underlag för standarder för nästa generations solvärmesystem och komponenter. Dessa standarder behövs för att nya och bättre produkter som inte omfattas av dagens standarder ska kunna komma ut på marknaden så fort som möjligt. Ett av resultaten från WP4 är ”omvandling från m2 (area) till Wth (effekt)”. Installerad solvärme har tidigare redovisats i m2 vilket gjort det svårt att jämföra med andra energislag som räknar kapaciteten i kW.

Därför har man tagit fram en formel för att räkna om installerad area till effekt i kW: P=0,7 kW/m2 *A Där P anges i kW och A i m2 Jämförelsen mellan globalt installerad solvärmekapacitet, solcells elektricitet och vindkraftsel visas i figur 3.

Valda resultat från WP5 Huvudspåret i WP 5 är att bedöma potentialen för solvärme i avancerade tillämpningar som avsaltning av havsvatten och kylsystem. För de olika processer som kan vara aktuella görs därför en undersökning: Tekniken beskrivs, energibehovet bedöms, kostnader, för- och nackdelar specifika för kombinationen med solvärme lyfts fram, utvecklingsstatus och möjlig kommersiell spridning analyseras. Rapporten där detta redovisas, och som bl.a. ska ligga till grund för valet av ett antal lovande systemlösningar som ska analyseras vidare, kommer inom kort att finnas tillgänglig på projekthemsidan. Workshops med industrideltagare Nationella workshops med industrideltagare kommer att anordnas för att sprida projektresultaten bland ett stort antal nationella experter. Förutom ren kunskapsöverföring är syftet med dessa workshops att initiera en diskussion inom solvärmeindustrin för att motivera till intensifierade ansträngningar i utvecklandet av nästa generations solvärmesystem. Följande nationella workshops planeras:
