RIBuild project is highly evaluated

The performance of RTU IESE and partners in the RIBuild project is highly evaluated in the European Union; the expected impact of the guidelines and the tools is considered very high, delivered information and knowledge has high quality. The RIBuild project summarizes the latest research on internal insulation in historic buildings, which is one of the most complex energy efficiency measures. Developed guidelines are applicable to historic buildings all over Europe. Anybody with an interest in building physics, retrofitting or energy efficient restoration can benefit from the guidelines. RTU realises this project together with partners from Denmark, Belgium, Germany, Italy,.

Looking back at the international scientific conference CONECT 2020

In the mid-May we had one of the most anticipated annual events – international scientific conference CONECT 2020, organized by RTU Institute of Energy Systems and Environment. This year it was a great challenge for participants and organisers because the conference was held online due to the worldwide Covid-19 outbreak. Nevertheless, CONECT 2020 conference was successful and fruitful. The conference was attended by 140 participants from Latvia and 19 foreign countries. For two days scientists presented their latest research at plenary sessions, panel sessions and poster sessions. On the third day the conference ended with a discussion on different scenarious.

Scientific articles in the project “Fog Unit”

The project “Individual Heat Supply with Integrated Fog Unit System (IFUS)” has published two publications on the results of a set of experiments submitted for publication in international journals indexed in the Web of Science and SCOPUS databases. Link Between Multivariables of Heat and Mass Transfer in a Scrubber. Case Study: Fog Unit Article summary - Combustion processes are one of the major sources of air pollution. The research uses a new, innovative flue-gas cleaning technology - a fog unit. Its purpose is to purify the flue gases produced by households. In the European Union, including Latvia, from 2020 a.

Experimental data of the fog unit

The project “Individual Heat Supply with Integrated Fog Unit System (IFUS)” collects experimental data at three boiler capacities (10 kW, 20 kW, 30 kW) and nozzles (MPL 1.51, MPL 1.12, MPL 0.77) used to obtain the data set to be analysed. The data analysis program Statgraphics XVII performed experimental data analysis to determine what parameters affect the capacity of the fog unit and the efficiency of particulate matter (PM). Regression analysis was performed to determine the parameters affecting the capacity of the fog unit, in which the dependent variables are: Flue gas temperature at inlet (tg1) and outlet (tg2); Water.

Fog Unit: calculation model to describe the operation of the fog unit

Within the framework of the activity 3.2, a program was developed, which includes a calculation model to describe the operation of the fog unit. The program is based on a pre-built mathematical model in the Excel environment (activity 1.3), which has been refined and transferred to another environment, facilitating faster calculations. Program written in PYTHON 3.7 using Visual Studio 2019. It includes the calculation of the thermal-physical parameters, the auxiliary equations and the calculation of changes in the main parameters. The main parameters, whose changes are considered in the model, are: injected water temperature, temperature of the flue gas, diameter.

Horizon 2020 BIOEASTsUP Project Launched!

The project “Advancing Sustainable Circular Bioeconomy in Central and Eastern European countries BIOEASTsUP” is funded by the EU Research and Innovation programme Horizon 2020 and began on 1st October 2019. Over the next three years, the consortium will have 21 partners from 14 different countries and will support the 11 Central and Eastern European (CEE) countries participating in the BIOEAST initiative to develop their national bioeconomy strategies and action plans for the transition to a sustainable bioeconomy. The RTU Institute of Energy Systems and Environment together with the Research Institute of Agricultural Economics from Hungary will develop a virtual toolbox.

Conference “Is it time for changes in the Latvian energy sector?”

What changes, endures. Rainis, “The Golden Horse” In the energy sector in Latvia in recent years we can observe the implementation of new, innovative and thoughtful projects. One of the last of these is the initiative of "Salaspils Siltums" Ltd. to start using solar energy in district heating. However, at the very core, we are still living the practice and thinking of 10-20 years or even earlier, which has resulted in the energy sector not developing as it could. No one can deny that in Latvia we still have huge potential in this sector that we are not using. Is this why we can.

World famous professor in system dynamics David Wheat started his lectures in Riga Technical University

On the 3rd of September guest lectures led by world famous professor David Wheat on system dynamics started for students of “Environmental Science” programme in the Institute of Energy Systems and Environment of the Riga Technical University. David Wheat received his master’s degree at Harvard University and his PhD in System Dynamics at the University of Bergen in 2007. David Wheat is past-president of the economics chapter of the International System Dynamics Society, is a member of the Scientific Committees of the international journals (“System Dynamics Review”, “International Journal of Pluralism and Economics Education”), and is a co-author of several.

Seminar “Sustainable and Flexible Energy Use”

Integrating renewable energy into existing systems; Multifaceted energy efficiency: different users, different options; Energy tariffs: from regulated tariffs to benchmark; These and many other questions will be answered in the seminar "Sustainable and Flexible Energy Use" on June 20 from 10:00-13:00, organised within EU Sustainable Energy Week. The seminar is organized by Institute of Energy Systems and Environment, Riga Technical University, Latvia. Lecturers have extensive experience in energy end-users (industry, municipalities, residential sector, etc.), as well as in integrating renewable energy into the Latvian energy sector. We are convinced that it is possible to reduce energy consumption by 5-15% without.

Looking back at the international scientific conference CONECT 2019

In the mid-May we had one of the most anticipated annual events - international scientific conference CONECT 2019, organized by RTU Institute of Energy Systems and Environment. The conference was attended by 110 participants from Latvia and 22 foreign countries. For two days, scientists presented their latest research at plenary sessions, panel sessions and poster sessions. On the third day the conference ended with a technical tour to the modern organic cosmetics factory of AS MADARA COSMETICS and a tour to Old Riga. Conference papers will be published in special issues of Journal of Environmental Management and Journal of Environmental.
