In the ever-evolving landscape of construction and energy efficiency, a groundbreaking study led by Ruxandra Cozmanciuc from the “Gheorghe Asachi” Technical University of Iași, has shed new light on the critical intersection of building performance and energy consumption. Published in the Bulletin of the Polytechnic Institute of Jassy: Constructions, Architecture Section, this research delves into the complexities of enhancing the energy performance of existing non-residential buildings, a sector that has seen a surge in both new construction and rehabilitation works over the past decade.
The study, which focuses on a non-residential building in Romania’s IVth climate zone, explores various scenarios to improve energy efficiency while accommodating a larger number of occupants. Cozmanciuc emphasizes the importance of integrating renewable energy sources and thermal rehabilitation works to meet the stringent performance indicators set by new legislation. “The key to reducing energy consumption lies in a holistic approach that addresses both the building envelope and its technical systems,” Cozmanciuc states.
The research highlights the necessity of increasing the thermal resistance of enclosing elements, reducing heat losses, and minimizing thermal bridges and air infiltrations. By simulating different scenarios using specialized software, the study analyzes primary energy consumption and equivalent CO2 emissions, providing a comprehensive view of the potential impacts of various energy-efficient strategies.
The findings are particularly relevant for the energy sector, as they offer practical insights into how existing buildings can be retrofitted to meet modern energy standards. This is not just about compliance; it’s about creating a sustainable future. “The integration of renewable energy sources and advanced thermal rehabilitation techniques can significantly reduce the carbon footprint of non-residential buildings,” Cozmanciuc explains. “This not only benefits the environment but also presents a compelling commercial opportunity for energy providers and construction firms.”
The implications of this research are far-reaching. As the demand for energy-efficient buildings continues to grow, driven by both regulatory requirements and market trends, the construction industry must adapt. This study provides a roadmap for achieving energy performance goals, offering a blueprint for future developments in the field. By understanding the interplay between building design, energy systems, and renewable sources, stakeholders can make informed decisions that drive innovation and sustainability.
The Bulletin of the Polytechnic Institute of Jassy: Constructions, Architecture Section, is a testament to the ongoing efforts to advance the field of building energy performance. As the construction industry navigates the challenges of energy efficiency, studies like Cozmanciuc’s will play a pivotal role in shaping the future of sustainable building practices.
