Ursula von den Leyen’s visit to RTU IESE. The New European Bauhaus States

RTU’s IESE tackles the challenge of combining technology, culture, and nature in one synergy. In the project "Improvement of building energy efficiency Technologies (I-BEET)" (No. 03000-3.1.2-e/163) focused on the transition from traditional to positive energy block we study both existing building stock supporting the Renovation Wave goals and new buildings promoting smarter technologies as well as the use of renewables available on-site. Our work in RTU’s Institute of Energy Systems and Environment always has been focused on human well-being in liveable surroundings without compromise to the environment. It should become the new lifestyle. During the President of the European Commission (EC) Ursula.

Podcasts “Sustainable Worlds” about sustainable energy – The newest episode “Clean energy- the only way!”

Podcasts “Sustainable Worlds” about sustainable energy The Nordic Council of Ministers' Office in Latvia in cooperation with the Institute of Energy Systems and Environment of the Riga Technical University offering a series of podcasts “Sustainable Worlds”. The newest podcast entitled “Clean energy- the only way!” is available for listeners. The newest podcast episode is focused on the challenges and opportunities sustainable energy will feature. Professor Peter Lund from Aalto University in Finland and professor Gatis Bažbauers from Riga Technical University in Latvia will reflect on topic about sustainable energy. Discussion is moderated by Dr. Kārlis Valters form the Riga Technical.

Online seminar “Financing Energy Efficiency in Baltic countries: lessons learned and future outlook”

Within the framework of the EU Green deal which aims to transform EU economies and achieve climate neutrality by 2050 and Recovery and Resilience Facility in the context of national energy and climate targets, a sufficient amount of investment in energy efficiency, renewable energy projects, and innovative technologies are among the most important issues to tackle. Therefore, in the framework of the project CIC2030 (Climate Investment Capacity 2030) workshop is organized to bring together policy makers, project developers, researchers, and financiers to exchange on lessons learned and discuss future perspectives on energy efficiency project financing. We invite you to.

Online seminar “Solutions to reduce energy costs in companies”

When thinking about company development, new markets and new products come first, there often might not be enough time to analyze and work on reducing existing energy costs. Therefore, within the framework of the CIC2030 (Climate Investment Capacity 2030) project, we’re organizing a seminar during which, together with energy sector professionals, we will look at real examples that can help reduce energy costs. Together we will think about the best possible energy efficiency measures in wood processing companies. We invite you to join the online seminar “Solutions to reduce energy costs in companies”, which will take place on December 11,.

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.

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.
