The paper analyzes approaches to modeling the processes of interaction of concentrated solar radiation with materials. The experimental results obtained on the synthesis of materials from a melt in a solar furnace are presented. The features of the interaction of concentrated solar radiation with materials are analyzed. The mechanisms are described and a model for the interaction of concentrated solar radiation with materials is created. A feasibility study is proposed for the technology of glass-based glass materials obtained on the Big Solar Furnace. 折りたたむ

Commercial buildings consume a significant amount of energy, contributing to greenhouse gas emissions and climate change. The adoption of energy-efficient technologies and practices can help reduce energy consumption and lower operating costs while improving occupant comfort and productivity. This research paper aims to explore the challenges, opportunities, and solutions related to energy efficiency in commercial buildings. The paper discusses the current state of energy efficiency in commercial buildings, identifies the key challenges, and highlights the opportunities for improving energy efficiency. The paper also presents the latest energy-efficient technologies and practices, including building automation systems, energy-efficient lighting, HVAC systems, and renewable energy sources. Finally, the paper concludes with recommendations for policymakers, building owners, and managers on how to promote energy efficiency in commercial buildings. 折りたたむ

Many renewable energy sources such as solar and wind energy are grown and well developed as the cost effective solution being widely used in Nigeria but the whole Africa and world at large has witnessed a dramatic increase, concern over environment and demand of energy have led the world to think about alternate energy sources such as wind, hydro, solar and fuel cells. The voltage multiplier cell was incorporated with the interleaved converter to design the DC to DC boost converter for the PV application. The proposed converter is supplied by 18V as an input voltage and produces 99V output and gives 95% of efficiency under no load and 94% under load conditions. The performance of the proposed topology was substantiated and the results achieved from the fabricated prototype are in good agreement with the design strategies. The effects of input parameters such as sun radiation and useful power input on PV system and DC-DC converter outputs were exploration for 14 days. Results confirmed that the DC-DC converter was perfectly designed and accurately constructed, when integrated with solar PV system, data were captured under no load and on load conditions. 折りたたむ

Promoting responsible energy usage in student hostels and residential buildings plays a crucial role in ensuring sustainable development. By implementing cost-efficient strategies for managing and conserving energy, both students and homeowners can not only reap economic and social benefits but also mitigate the adverse environmental effects associated with energy consumption. Unfortunately, student hostels and residential buildings in developing countries like Ghana are falling behind in the adoption of energy efficiency and management practices, thereby missing out on valuable implementation opportunities. This study investigates the potential for energy efficiency and conservation measures in student hostels, specifically the GETFUND hostel of the University of Energy and Natural Resources in Ghana. The hostel's monthly energy consumption is approximately 64,929.458kWh, which translates to $5,667.20. The objectives of the study include analysing the current electricity consumption pattern, identifying energy misuse, and recommending measures to save energy, as well as calculating the financial benefits of implementing energy management practices. The methodology employed is an energy audit approach. The results of this study can contribute to overall energy conservation efforts in Ghana and may be applied to other university residence halls in sub-Saharan African countries with similar climatic and energy-use characteristics. In a broader sense, the primary objective of this study is to enhance the energy efficiency of the GETFUND hostel and minimize energy wastage, resulting in substantial financial savings. 折りたたむ
