Ulaanbaatar (Mongolia) is the coldest capital city in the world with approximately 98% of its heating demand satisfied by means of coal-burning stoves. This leads to enormous air pollutant emissions, with Ulaanbaatar being one of the top five most polluted cities in the world. In this study, an innovative solar hybrid heating system for the Mongolian scenario was used, which was based on the operation of a solar field composed of four series-connected evacuated tube heat pipe collectors, coupled with a thermal energy storage. The solar hybrid heating system was simulated and analyzed using the software TRNSYS. The simulations were designed to satisfy the heating demand of a typical single-family detached house located in Ulaanbaatar and were carried out with and without considering the soiling effects on the solar system operation. The overall performance of the proposed plant was compared with those associated with different fossil fuel-based Mongolian conventional heating systems, in order to assess the potential energy, environmental and economic benefits. The results highlighted that the proposed plant allowed for the obtainment of significant reductions in terms of primary energy consumption (up to 34.6%), global CO2 equivalent emissions (up to 52.3%), and operating costs (up to 49.6%), even if the expected return on the investment could be unacceptable.

“…Another key element of energy efficiency is the availability of engineering systems that allow the use of "passive" energy sources, such as geothermal, light and wind sources. In conditions of a "moderately cold climate", with a small number of light days per year, as well as features of the relief and vegetation, the use of "passive" sources is limited only by geothermal sources [3]. In Finland, one of the most common heating methods is the use of heat pumps with a geothermal circuit using the "ground-to-water" or "ground-to-air" technology.…”

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.

“…On the other hand, Erdenedavaa et al 28) investigated the applicability of the solar thermal system for space heating based on the measurement of a detached house equipped with solar collectors in Ulaanbaatar. Pillarisetti et al 29) monitored the performance of electric heat pumps tailored to cold climate in baishins and gers. Although it is a well-known fact that a frigid climate generally worsens the performance of heat pumps for space heating, their long-term observation in houses where occupants resides as usual shows acceptably moderate performance.…”

In Ulaanbaatar, Mongolia, 30% of households in urban settlements live in traditional mobile dwellings-gers. This study outlines urban gers based on a field survey of 49 households. The authors analyse space heating and thermal characteristics of ger envelopes, which are essential factors for the emission of air pollutants during winters. The results suggest the necessity of urgent policy implementation of the change of coal stoves to other appliances with better energy performance and lower pollutant emissions. Further, there is a need for new, customised methods to improve the thermal insulation of gers, based on local economy and needs.
