| 1 | Title of project: The hybrid ventilation device with increased functionality Period: 2017–2020 Title of the Programme, sub-programme: "Targeted research in the area of smart specialization", "High-level research group research" |
The aim of the work is to create a prototype of only renewable energy using hybrid (partially mechanical, partially natural) air handling unit which, acting on the basis of a wind turboejective ventilator (lit. TEV), would increase the functionality of a ventilation system using energy of stochastically changing wind, i.e. would ensure longer and more stable air supply in ventilated areas. This will include an analysis of research on renewable energy using hybrid ventilation solutions, their components (including energy storage), and the algorithm and model of the mechanical, thermodynamic, aerodynamic computation of the patented combination of the selected components. A patent application for increased functionality for a hybrid air handling unit is also prepared and submitted. The algorithm and model of the selected device components are validated by the experimental investigations. A prototype, based on the parametric analysis performed with the created model, was made and its experimental experiments were carried out. The results will be published in two foreign journals with a citation index and in proceedings of two international conferences. |
| LIFE22-CET-SET_HEAT – Supporting Energy Transition and Decarbonisation in District Heating Sector | The project aims to accelerate the energy transition and decarbonization of district heating (DH) in four targeted Eastern European countries through the integration of low-grade heat sources in high-temperature DH networks. The overall concept is to trigger tangible investment projects through the direct involvement of DH companies and relevant stakeholders in a collaborative planning process, which aims at sharing ideas and joint development of replicable model investment projects. The project will also feature a significant transfer of knowledge from numerous previous EU and national projects and the mobilization of stakeholders. It includes tailored activities focusing on filling knowledge gaps, developing necessary skills and competences, stakeholder outreach, as well as extensive communication, dissemination and exploitation. Project partners and key stakeholders will collaboratively develop technical and non-technical solutions for follower DH companies and the sector. The project will directly support four DH companies, which operate high-temperature DH systems, in preparation of investment plans to fulfill the revised criteria for 'efficient district heating and cooling' defined in the Energy Efficiency Directive for the period from 2026 to 2035, and pave the way for further developments. The number of DH systems directly involved in the project (owned by project consortium partners) is 20. The participating countries are Poland (Silesian University of Technology – coordinator), Lithuania, Romania, Croatia and Denmark. Lithuania is represented by Vilnius Gediminas Technical University and the DH company Vilniaus šilumos tinklai. Giedrė Streckienė is the project manager of the VILNIUS TECH part of the project. https://setheat.polsl.pl/ |

| 2 | Title of project: Evaluation of seasonal thermodynamic efficiency of air handling unit (EXOPTAS) Period: 2015–2017 Title of the Programme, sub-programme: Research group projects, Research Council of Lithuania |
By choosing different parameters of the exergy flow estimation - Carnot factor and coenthalpy – two independent methods have been prepared for the heat recovery process thermodynamic (exergy) efficiency of the air handling unit and its components and for the exergy flows that form this efficiency to calculate. New scientific findings were obtained with the application of the methodology elaborated and purposefully developed: the variation of values distribution, depending on the ambient temperature, of the different technological schemes ventilators of air handling unit, heat recovery device and heat pump heat exchangers, compressor's power and combinations of energy flows energy efficiencies, exergy flows and destroyed energy. The relation between the freon temperature in the evaporator and its and condensers specific heat flows' and ventilated room temperatures are revealed when ambient temperature of the reference is changing. Experimental studies have shown that the management of these influential parameters is possible with modern technological implements. An analytical study of the two alternatives of the air handling unit for two different locations (Vilnius and Paris) has shown that the average and maximum exergy efficiency of the heating season for the same installation varies between locations. In addition, the optimal heat pump regulation mode identified in the work allows obtaining seasonal exergy efficiencies of 1.4 times in Vilnius and 1.7 times higher in Paris than in the traditional case. The results show the possibilities of exergy analysis to evaluate and compare the operation of equipment under different climatic conditions. An algorithm was prepared which, in the chosen programming language and environment, provides the possibility to create a computer program for assessing the energy and exergy seasonal efficiency of air handling unit. The project's scientific results have been published in 5 Web of Science Core Collection works. In proceedings of the 1 st International Conference and in 4 articles. 1 of these is in Q1 journal, 2 is in Q2 journals. 1 publication is being corrected after review in C1 journal (ISSN: 1359-4311). |
| 3 | Title of project: Model of the renewable energy sustainable use in buildings (PATEnMOD) Period: 2012–2014 Title of the Programme, sub-programme: National Research Programmes (NRP) “Future Energy” |
The aim of the project is to develop and test a model of the assessment of the efficiency of renewable energy-using systems in building. The project product is the conception of the building in specific area and the concept of preliminary solution modeling technology, which quantifies its energy sustainability in the algorithm created in this project by combining several specialized digital modeling tools with specially designed interfaces. The project's scientific results have been published in 6 Web of Science Core Collection works. In proceedings of the 1 st International Conference and 5 articles. 3 - Q1 journals, 2 - Q2 journals. One of them received enough citations to place it in the top 1 % of the academic field of Engineering based on a highly cited threshold for the field and publication year (2016). |
| 4 | Title of project: Network for Using BIM to Increase the Energy Performance - Net-UBIEP Period: 2017-2019 Title of the Programme, sub-programme: Project of Horizon 2020 programme of the European Commission |
Net-UBIEP aims at increasing energy performance of buildings by wide spreading and strengthening the use of BIM, during the life cycle of the building. The use of BIM will allow to simulate the energy performance of the building using different materials and components, both the to be used in the building design and/or in building design refurbishment. BIM, which stands for Building Information Modeling, is a process that lasts for all the building life cycle from the design phase through the construction, management, maintenance, demolish. In each of this phase is very important to take into account all the energy aspects in order to decrease the environmental impact of the building during its life cycle. BIM Qualification Models to tackle the problem of energy competences gap in the existing buildings sector as a whole. Each BIM Qualification Model will be composed by a BIM Training Scheme and a BIM Qualification and Certification Scheme. |
| 5 | Title of project: Sustainable Zero Carbon ECO-Town Developments Improving Quality of Life across EU - ECO-Life Period: 2009–2015 Title of the Programme, sub-programme: FP7 Energy WP, CONCERTO |
Sustainable Zero Carbon ECO-Town Developments Improving Quality of Life across EU. The aim of the "ECO-Life project" is to demonstrate innovative integrated energy concepts throughout three countries in the EU where urban areas will be transformed into CO2-neutral communities. The three communities in the project are: Høje Taastrup in Denmark, Kortrijk in Belgium and Birstonas in Lithuania. The project started up in January 2010 and will end in January 2016 and in the project period there will be erected new low energy houses and renewable energy production. Furthermore buildings with several different functions will be refurbished into minimum existing building regulations. However, many of the activities and the transformation of the three communities will carry on beyond the project. The project is funded under the CONCERTO Initiative. |
