In the quest to enhance energy efficiency and durability in residential buildings, a groundbreaking study led by Artashes Petrosyan from the National University of Architecture and Construction of Armenia has shed new light on the critical role of thermal insulation in managing moisture and thermal-humidity regimes. Published in the Journal of Architectural and Engineering Research, the research delves into the intricate relationship between thermal insulation and the formation of condensate zones in building structures, offering valuable insights for the construction and energy sectors.
The study, which focused on two prevalent building types in Armenia—5-story tuff and 9-story reinforced concrete (RC) panel structures—revealed that the type, thickness, and installation method of thermal insulation materials significantly impact the formation of condensate zones. This finding is particularly relevant for buildings in different climatic zones, where varying vapor permeability rates can affect the physical condition and thermal properties of surrounding structures.
Petrosyan’s research underscores the importance of selecting the appropriate thermal insulation material and thickness to mitigate condensation and enhance energy efficiency. “By understanding the specific requirements for thermal insulation in different climatic conditions, we can not only reduce energy consumption but also extend the lifespan of building structures,” Petrosyan stated. This insight is crucial for construction professionals and energy sector stakeholders aiming to optimize building performance and reduce operational costs.
The study identified that in tuff cladding structures, condensate zones form in cities like Yerevan, Gyumri, Hrazdan, Vanadzor, and Sevan, but not in Kapan. However, by employing different types of thermal insulation materials, this phenomenon can be effectively avoided. For instance, the recommended thickness of foamed polystyrene thermal insulation in buildings with a tufa structure varies from 4 cm to 7 cm, depending on the city. In the case of RC panel construction, the thickness of expanded polystyrene ranges from 7 cm to 11 cm, again varying by location.
These findings have significant commercial implications for the energy sector. By implementing the recommended thermal insulation strategies, buildings can achieve the required thermal resistance, reduce fuel consumption, and minimize the need for costly maintenance and repairs. This not only enhances the energy efficiency of buildings but also contributes to long-term sustainability goals.
The research highlights the need for tailored approaches to thermal insulation based on local climatic conditions. As Petrosyan noted, “One size does not fit all when it comes to thermal insulation. Understanding the specific needs of different regions is key to optimizing building performance and energy efficiency.”
This study, published in the Journal of Architectural and Engineering Research, provides a comprehensive framework for construction professionals and energy sector stakeholders to make informed decisions about thermal insulation. As the industry continues to evolve, the insights gained from this research will undoubtedly shape future developments in building design and energy management, paving the way for more sustainable and efficient residential structures.
