Special Issue Information

Dear Colleagues,

The European Green Deal’s goal is to radically reduce greenhouse emissions by at least 55% by the year 2030, aiming at making Europe the first climate-neutral continent in the world by 2050. Environmentally friendly, energy-efficient buildings with advanced building physics solutions and renewable energy sources will play an important role in achieving this goal. This goal prompts researchers to look for new solutions in building physics and renewable energy focusing on improving the buildings’ efficiency, considering indoor climate, local conditions, and cost-effectiveness.

Without renewable and clean energy as well as a deep understanding of science going around modern energy-effective structures, we never provide enough protection for our planet in case of devastating climate change and galloping environmental pollution. That is why the aim of this Special Issue is to collect the state of the art on theoretical, experimental, and economic studies covering various areas of buildings’ physics and renewable energy, enhancing a deeper understanding of contemporary trends in the abovementioned fields. Researchers are encouraged to share their original work in the area of building physics and renewable energy.  This Special Issue covers a broad range of topics:

  • New insulation and building envelope materials;
  • Building partitions (e.g., energy-efficient, with a thermal barrier, made of phase change materials);
  • Advances in air, heat, and moisture modeling;
  • Case studies of new building physics solution application;
  • Interactions with the building’s internal environment, inhabitants, materials, construction type, and systems applied;
  • Innovative building’s design solution and their energy performance;
  • Innovations in renewable energy solutions;
  • Hybrid renewable energy systems;
  • Safety-related aspects of renewable energy;
  • Advances in various renewable energy technologies (biomass, photovoltaic, solar thermal, wind energy, ocean energy, and hydro power technologies).

Creative extensions of the abovementioned topics are also welcome.

Thermal comfort affects not only the well-being of the occupants of a building but also the effectiveness of their learning and work efficiency. It can be disturbed if the ventilation airflow is increased when improving indoor air quality. When natural ventilation is used in the fall and winter period, the supply air temperature is low, resulting in a lack of thermal comfort. In existing buildings, there is often no place for mechanical ventilation; hence, decentralised façade ventilation units are increasingly used. The article presents an analysis of thermal comfort in rooms with this type of unit equipped with heat recovery exchangers of different efficiencies. Studies have shown that the alternating supply/exhaust airflow and the related unevenness of air streams flowing through the heat accumulator cause an inflow of low-temperature air, resulting in thermal discomfort. The highest value of the PMV index was −1.6, and the lowest was −4.1, which means that 54.8 to 100% of the occupants are dissatisfied with their thermal comfort. This means there is a need to change the construction of inlet/exhaust vents so that the stream of supply air is not directly parallel to the floor. In addition, the use of an air heater should be considered. Full article

The paper analyses thermal comfort in intelligent and traditional buildings in Poland. It provides a comprehensive study on the subjective assessment of indoor environment conditions as well as on parameters that influence human thermal sensations and preferences. Direct measurements of physical parameters (e.g., air and globe temperature, relative humidity) as well as simultaneously conducted anonymous questionnaire studies were used to provide the necessary data. The study covered all seasons and a large number of participants representing various age groups and body build types, who completed a total of 1778 questionnaires. The results indicate that typically smart buildings offer higher levels of thermal comfort than the traditional ones and that people tend to prefer warmer environments. Moreover, it has been observed that the BMI index, air movement and the number of people per surface area can have an impact on the perceived thermal sensations. Full article

Problems with inaccurate prediction of electricity generation from photovoltaic (PV) farms cause severe operational, technical, and financial risks, which seriously affect both their owners and grid operators. Proper prediction results are required for optimal planning the spinning reserve as well as managing inertia and frequency response in the case of contingency events. In this work, the impact of a number of meteorological parameters on PV electricity generation in Poland was analyzed using the Pearson coefficient. Furthermore, seven machine learning models using Lasso Regression, K–Nearest Neighbours Regression, Support Vector Regression, AdaBoosted Regression Tree, Gradient Boosted Regression Tree, Random Forest Regression, and Artificial Neural Network were developed to predict electricity generation from a 0.7 MW solar PV power plant in Poland. The models were evaluated using determination coefficient (R2), the mean absolute error (MAE), and root mean square error (RMSE). It was found out that horizontal global irradiation and water saturation deficit have a strong proportional relationship with the electricity generation from PV systems. All proposed machine learning models turned out to perform well in predicting electricity generation from the analyzed PV farm. Random Forest Regression was the most reliable and accurate model, as it received the highest R2 (0.94) and the lowest MAE (15.12 kWh) and RMSE (34.59 kWh). Full article

Wooden construction constitutes a specific branch of the building industry that focuses on high-quality materials, a developed sense of aesthetics connected with comfort and functionality, and concern for ecology and durability. This type of construction has a positive effect on human quality of life. This article focuses on modular frame construction and technological aspects of wooden houses built according to Canadian or Scandinavian technologies. Taking weather conditions of Scandinavian countries into consideration, timber is a popular building material, which, when preserving certain parameters such as density of rings, may provide durability of a modular wooden building even up to 200–300 years. This article is a review and presents the possibility of producing frame buildings in Europe (Poland) in accordance with the applicable standards, including a heat transfer coefficient U = 2 [W/(m²·K]. In Poland, wooden frame buildings can be traced back to the 14th century. Wooden frame buildings and modular wooden frame buildings were produced even earlier in Norway. Wooden construction continued in the mid-1800s in various forms (with wooden filling and/or panels). In the mid-1900s (1941), certain dimensioning became regulated by law, which then applied to different types of insulation fillings. Prefabricated modular wood frame houses were common in the 1960s.
