“…A similar trend is in Sweden, where the best RET is considered HPP, and the worst alternative is solar PV -similar as in Latvia. As to Lithuania's and Denmark's results, there Turning to the distribution of RET ranks according to literature review [14], Denmark remains as the leader in solar technologies due to its contribution to electricity production, however, the most popular RET, in general, is WPP. The results of TOPSIS evaluation confirms results the of the study [17] in Sweden, where bio-energy installations are less preferable in the context of heating systems.…”

“…Also, by cause of marginal costs for heat pump technology (use of electricity to produce heat) and solar technologies (energy received directly from the sun), provides conditions where solar collectors seem more understandable for the end user. Moreover, one big drawback is the tendency to have lower efficiency than estimated [14].…”

The development of renewable energy technologies (RET) depends on a wide range of criteria and regulations. To evaluate which RET (solar photovoltaic (PV), wind power plants (WPP), hydroelectric power plants (HPP) or bio-energy plants) have the greatest potential in Latvia, the most suitable approach is a multiple criteria decision making (MCDM). The proposed MCDM methodology involves TOPSIS model based on information entropy, which contributes as a criteria weighting tool. The study investigates seven main criteria from technical, economic, environmental and social aspects. Firstly, each alternative country is analysed due to the chosen RET criteria. Secondly, the assessment is extended, comparing specific data with Latvia’s MCDM of RET results. The research results show that, according to the best available examples of RET, hydro energy plants still play a substantial role for Latvia, the most promising RET development is based on bio-energy and wind renewable energies.

In the article the author considers one of the most important factors of life support – the creation of an energy-efficient and healthy microclimate country house through the use of complex engineering systems including the use of “passive” energy sources. Based on the results of the foreign and Russian market analysis of energy-efficient houses, the reasons for the low construction pace of such houses in Russia are estimated. A constructive engineering solution is proposed that can increase the efficiency using the modern heating, conditioning and humidification systems, thereby making them economically feasible and affordable for mass use.

“…First, attempts have been made to shift energy consumption to off-peak hours when the emissions from energy generation are the lowest [25,26]. Second, low-emission heating systems that rely on renewable energy sources have been popularized in newly developed or upgraded buildings [27,28].…”

Assessment of Reducing Pollutant Emissions in Selected Heating and Ventilation Systems in Single-Family Houses

The article presents the results of a study aiming to select the optimal source of heat for a newly designed single-family home. Commercial software was used to compare heating and ventilation systems involving a bituminous coal boiler, a condensing gas boiler, a biomass boiler, a heat pump with water and glycol as heat transfer media. The effectiveness of natural ventilation, mechanical ventilation with a ground-coupled heat exchanger, and solar heater panels for water heating were evaluated. The analysis was based on the annual demand for useful energy, final energy, and non-renewable primary energy in view of the pollution output of the evaluated heating systems. The analysis revealed that the heat pump with water and glycol was the optimal solution. However, the performance of the heat pump in real-life conditions was below its maximum theoretical efficiency. The biomass boiler contributed to the highest reduction in pollutant emissions (according to Intergovernmental Panel on Climate Change Change guidelines, carbon dioxide emissions have zero value), but it was characterized by the highest demand for final energy. Mechanical ventilation with heat recovery was required in all analyzed systems to achieve optimal results. The introduction of mechanical ventilation decreased the demand for final energy by 10% to around 40% relative to the corresponding heating systems with natural ventilation.
