In the context of global warming, the focus on applying and researching double–skin facade (DSF) systems to reduce energy consumption in buildings has significantly increased. However, researchers have not thoroughly examined the performance and applicability of DSFs in severe cold regions with high winter heating demands. This study aims to evaluate the potential application of DSFs in the harsh cold cities of Northwest China and investigate their role in enhancing energy efficiency in large public buildings. Through energy consumption simulation and a comprehensive evaluation using the TOPSIS entropy weight method, the effects of applying 20 DSF schemes in four cold cities in Xinjiang (Kashgar, Urumqi, Altay, and Turpan) were analyzed. The experimental results indicate that the average EUI energy–saving rates in Kashgar, Urumqi, Altay, and Turpan are 64.75%, 63.19%, 56.70%, and 49.41%, respectively. South–facing orientation is deemed optimal for DSF in Xinjiang cities, with the highest energy–saving rate reaching 15.19%. In Kashgar, the energy–saving benefits of west–facing DSF surpass those of north–facing DSF. Conversely, the order of orientation benefits for other cities is south, north, west, and east. An analysis of heating, cooling, and lighting energy consumption reveals that Box Windows exhibit superior heating energy efficiency, while Corridors are more effective for cooling. This characteristic is also evident in the optimal installation orientation of various types of curtain walls. Given the relatively higher demand for heating compared to cooling in urban areas, Box Windows yields significant benefits when facing south, west, or north; conversely, if there is a high demand for urban cooling, Corridors should be considered in these three directions. Multistorey DSF systems are suitable for east–facing buildings in Xinjiang cities. Selecting suitable DSF schemes based on specific conditions and requirements can reduce building energy consumption. The research findings offer theoretical guidance for designing and implementing DSF in diverse cities in cold regions.

The present study provides comprehensive analyses of a newly constructed passive energy-efficient building located in Harbin, China, which is a prime example of how to design a passive building that withstands the severe cold climate in northeast Asia. Conduction transfer functions of heat flux equilibrium are employed to simulate energy consumption characteristics of the paradigm passive building. The climatic conditions in severe cold region are analyzed, and the energy-saving designs in the studied engineering cases are summarized for their practical applications. Building physical models are established to perform numerical simulation analyses on the passive building paradigm in northeast Asian frigid zone. The dominant technical parameters of envelope structure affecting energy consumption in severe cold region, including thermal insulation thickness and heat transfer coefficient of building envelope, as well as window-to-wall ratio for each building facade, are taken into consideration as simulation variables to calculate cooling load, heating load, electricity consumption, and CO2 emission, which account for energy efficiency of passive buildings. The simulation results demonstrate the high energy-saving potential of the proposed passive building design and render the optimal energy-efficient parameters suitable for severe cold regions, which can reduce energy consumption and CO2 emission while ensuring comfort for occupants. The present study provides a theoretical reference for envelope structures of passive buildings in severe cold regions, which is of great significance to the development of green buildings and relevant policies.

The application of renewable energy sources is a current trend today due to the limited sources of fossil. A substantial part of these energy sources is solar radiation. The development of electricity prices was significantly affected by two global crises, the COVID-19 pandemic and the energy crisis associated with the Russia-Ukraine conflict. The essence of the article is to compare the economic sense and appropriateness of investing in a photovoltaic power plant system and its return over time, considering the prediction of the development of electricity prices between 2020 and 2023 and subsequently also with a 15-year price prediction. The article deals with investment, energy consumption and financial evaluation of a PV system with PV panels installed on the ventilated façade of a residential building in the Czech Republic. The conclusions of the article show that the increase in investment in the PV panels themselves between 2020 and 2023 is a crucial factor for the return of the entire system. Predictive models of the development of electricity prices and associated liquidity of the investment also play a significant role in this issue.
