In the sweltering heat of summer, buildings often become ovens, trapping heat and driving up energy costs as air conditioning systems work overtime. But what if the very structure of a building could help mitigate this heat, reducing the need for excessive cooling and saving energy? This is the question that Vasyl Zhelyh, a researcher from Lviv Polytechnic National University, has been exploring in his latest study published in Energy Engineering and Control Systems (Energetychna inzheneriya ta systemy keruvannya).
Zhelyh’s research delves into the heat resistance of a building’s external construction, a critical factor in determining indoor temperatures. “The thermal protection of a building, especially during the summer, is crucial for maintaining a comfortable indoor climate,” Zhelyh explains. His study focuses on how solar radiation affects the external construction of buildings during the summer months, a factor often overlooked in building design.
One of the key findings of Zhelyh’s research is the relationship between the solar radiation absorption coefficient of a building material and the amplitude of temperature fluctuations. In simpler terms, some materials absorb more heat from the sun, causing the building’s temperature to fluctuate more dramatically. By choosing materials with a lower absorption coefficient, builders can reduce these fluctuations, keeping the building cooler and more comfortable.
But it’s not just about the materials. Zhelyh also investigated the influence of airflow in July, a critical parameter that affects the heat transfer coefficient of the outer surface of a building. “Airflow can significantly impact how much heat is transferred from the outside to the inside of a building,” Zhelyh notes. By understanding and optimizing this factor, builders can further enhance a building’s heat resistance.
So, what does this mean for the energy sector? As buildings become more energy-efficient, the demand for cooling energy decreases, leading to significant cost savings. Moreover, by reducing the need for air conditioning, buildings can lower their carbon footprint, contributing to a more sustainable future.
Zhelyh’s research could shape future developments in the field by influencing building design and material selection. As the demand for energy-efficient buildings grows, so too will the need for materials and designs that can withstand the summer heat. This research provides a roadmap for builders and architects, helping them make informed decisions about the external construction of buildings.
As we look to the future, it’s clear that the energy sector will continue to evolve, driven by the need for sustainability and efficiency. Zhelyh’s work is a step in this direction, offering valuable insights into how we can build better, more energy-efficient structures. As the world continues to warm, this research could prove invaluable in the fight against climate change.
