What do Circular Strategies Mean for Current HVAC Systems in Utility Buildings?

Abstract

This research extensively examines the pivotal shift toward circularity within the European construction and building sector, with a specific emphasis on HVAC systems in utility buildings. It commences by underscoring the pressing urgency precipitated by the Paris Agreement of 2015 and subsequent climate objectives, necessitating reductions in greenhouse gas emissions and resource utilization. The construction and building sector's notable contributions to energy consumption, waste production, and material extraction highlight the imperative to address circularity within this industry.
The report delves deeply into the notion of the circular economy (CE), emphasizing its potential to disassociate economic growth from resource depletion and waste generation. While acknowledging the growing scholarly and corporate interest in CE, exemplified by industry giants such as Philips and IKEA, this study highlights the limited practical application of circular principles, particularly within the HVAC systems sector.
Recognizing the multifaceted and varying interpretations of circularity, the report seeks to demystify the concept by conducting a thorough literature review and interviews. Through a thematic analysis, it identifies existing challenges, proposes potential solutions, and evaluates the feasibility of implementing circular strategies for HVAC systems. Key findings encompass project-specific considerations, the influence of location and climate, and the imperative need for legislative reforms to expedite the transition.
Ultimately, the research provides a valuable starting point for MEP consultants, equipping them with a pragmatic decision support framework and a categorized repertoire of circular strategies. It encourages industry professionals to embrace circularity in HVAC design, bridging knowledge gaps and promoting sustainable practices. While acknowledging the study's limitations, including its qualitative nature and potential for bias, this study calls for future research to validate the framework through real-world cases, expand performance evaluation criteria, and advocate for policy reforms across the broader built environment. In summary, this study constitutes a vital stride toward fostering circularity and sustainability within the construction and HVAC sectors.
