Humans spend 90% of their time indoors therefore proper air quality in buildings is crucial for human health and productivity. The problem with poor air quality is usually found in buildings with no mechanical ventilation. Contrary, modern office buildings, which are usually equipped with mechanical ventilation, are often over-ventilated. The reason is usually related to lower-than-designed buildings’...
One of the main problems of the modern world is the search for and supply of renewable energy resources that could compete with oil and natural gas. In recent years, the world is entering the era of biotechnology, which uses renewable raw materials to produce energy and materials. One of the sources of alternative types of fuel is peat, which is the cheapest type of fuel for the population, raw material...
This article presents the analysis of the actual indoor climate parameters of an existing supermarket, which influence the energy consumption of the building's HVAC systems. The study is performed using the data of the Building Management System (BMS) of the analyzed supermarket. The functionality of HVAC systems' equipment, control solutions, actual thermal comfort, and air quality parameters were...
Heat losses caused by ventilation systems significantly affect energy consumption in buildings. Therefore, it seems reasonable to look for solutions to improve the efficiency of heat recovery and storage in ventilation systems. One example of such solutions are thermal energy storage systems using phase change materials (PCM), which can be a way to improve the thermal performance of a building. Utilizing...
Effective energy use plays a crucial role in the conservation of energy sources. The recovery of waste energy is one of the available energy saving potentials and can be the possibility of ensuring the energy needs of commercial buildings. To date, research on heat recovery from wastewater treatment has focused mainly on the heat potential of wastewater evaluation and technologies to apply this energy...
The global pandemic COVID-19 caused Ukrainian institutions continued their work in a blended learning mode or completely switched to remote mode. The paper analyzes the university educational building energy consumption for the heating season under quarantine and normal conditions. Building dynamic energy model in the DesignBuilder software was created. According to the results of modeling partial...
