  • Life Cycle assessment and data envelopment analysis approach for the selection of building components according to their environmental impact efficiency a case study for external walls
    Journal of Cleaner Production, 2015
    Co-Authors: Diego Iribarren, Antonino Marvuglia, Paula Hild, Melanie Guiton, Emil Popovici, Enrico Benetto
    Abstract:

    Abstract Environmental criteria have to be taken into account when it comes to selecting a specific building component among a set of candidates with the same function. This article presents a methodological approach – based on both Life Cycle Assessment (LCA) and Data Envelopment Analysis (DEA) – for the selection of building components according to their environmental impact efficiency. A three-step LCA + DEA approach is proposed and tested through a case study for 175 external walls. The three steps of this approach involve data Collection, Life Cycle impact assessment, and DEA of the sample of building components using environmental impacts as DEA inputs. Overall, from the availability of multiple data on the material and energy flows of each building component, the method provides decision makers with eco-efficiency scores and environmental benchmarks. A cautious definition of the set of candidates is critical, as relative efficiency scores are calculated. Data availability and functional homogeneity regarding the building components evaluated are the key requirements for the general use of the method. The three-step LCA + DEA approach proposed is proven to be a useful method to enhance decision making and environmental benchmarking in the building sector.

  • implementing Collection Life Cycle management
    Charleston Library Conference, 2016
    Co-Authors: Annie Belanger
    Abstract:

    In a time of increasing physical Collection space pressures and rapidly evolving higher education institutions, a holistic understanding of the Collection Life Cycle, a strategic approach to Collection development and retention, and increased stakeholder engagement is needed. Some librarians struggle with what materials to withdraw, especially if there is faculty opposition, and how to move forward collaboratively. This article will explore leveraging the experience of leading the local culture shift in a large Association of Research Library, the principles, policies and methods required to shift mental models towards what must be retained, facilitating withdrawal decisions, and connecting Collection development with ongoing Collection management. Why Collection Life Cycle Management? The last decade has been a time of reduction in stack space, for a wide range of reasons. Increasing pressure to ensure that precious square footage is focused on user needs has precipitated a reduction of stacks in many libraries. Off‐site storage facilities are notoriously full, with some seemingly on Life support. Increasingly, libraries are having to weed print Collections, whether in the campus libraries or offsite storage. There has been a range of success based on stakeholder management and selector engagement. Many struggle with what materials to withdraw, especially if there is faculty opposition. The just‐ in‐case approach of Collection building is set in direct conflict when there is discussion of withdrawal—“How do we know this won’t be valuable in 10, 20, 50, 100 years?” The very essence of the definition of research libraries since the end of WWII is challenged by the need to withdraw beyond basic housekeeping. Evidence‐based practices are challenged when so much emotion and the definition of a profession is tied into the Collections. A holistic understanding of the Collection Life Cycle, along with a strategic approach to Collection retention, assists a library in moving the conversation from one of loss to one of empowerment and proactive engagement. Collection Life Cycle management (CLM) shifts mental models towards what must be retained, facilitating withdrawal decisions and connecting Collection development with ongoing Collection management. Further, CLM allows us to enhance stakeholder engagement at the level of overarching principles and areas of focus, and not at the title level, which has been found to be an impediment to good process management. It allows us to create multiple paths for material to move through, with a clear understanding of these paths and their associated intentions. It gives us permission to buy materials that have at most a midterm use and flag these for early withdrawal. It provides a cohesive framework to manage Collections from the start to the end of their Life Cycle. Exploring a Shift to a CLM Approach The road to implementing CLM will vary among institutions, in part due to the selector model in place and its history. Here, I will attempt to breakdown what is often an organic model with overlap into a set of concrete steps. Any one institution may be starting at any one step, depending on their Collection culture. The first step, if there is such a concrete thing, will be to create buy‐in for the concept. I suggest breaking this process down into manageable pieces. To begin, acquire a solid understanding of where your institution is and the gaps that need to be filled before a culture shift can occur. At Copyright of this contribution remains in the name of the author(s). http://dx.doi.org/10.5703/1288284316245 Collection Development 142 Waterloo, a palpable difference in the approach in thinking to Collections occurred after five years. The second step, and one your institution may have completed, is to create Collection development policies and, if possible, an overarching Collection development strategy. Collection development policies clearly articulate what is being purchased, and why and by whom, defining the incoming materials. Sometimes, they provide a way to refuse requests for materials that do not fit the goals of the Collection. The acceptance of donations should align with these policies to ensure a cohesive Collection. The third step in moving to CLM is to get buy‐in for Collection evaluation. This is commonly perceived as a task that requires a great deal of time; however, the benefits are profound. Collection evaluation  Strengthens decisions regarding the Life Cycle of a Collection  Ensures that individual Collections encompass materials that effectively meet the changing research needs of its users; gives opportunity to identify and remedy a Collection’s weaknesses; exhibits proactive engagement with a Collection  Helps maintain librarians’ accountability to users, academic departments, and stakeholders In critically asking questions, librarians will determine the unique facets and focal points of a Collection, aiding them in the selection of evaluation methods to target key materials for retention. I will not explore Collection evaluation methods in this paper, but rather the high‐level questions that frame the evaluation.1
