Maintenance for historic buildings: A current perspective

Purpose – It is well understood that maintenance is critical to the survival and in‐service use of any building. Despite recognition that the best way of protecting and maintaining historic buildings is to undertake a combination of proactive and reactive maintenance, it is rarely adopted or implemented, and when it is undertaken it often results in varying degrees of success. Maintenance theory currently exists, but fails to be realised in practical application and implementation. It is the purpose of this paper to ask why this failure is occurring.Design/methodology/approach – The paper is composed of a critical review of existing literature, highlighting some of the major issues affecting maintenance implementation. It also reports the early stages of proposed research ongoing at Heriot‐Watt University.Findings – Despite recognition in the literature of the need to maintain historic buildings, this review suggests that the ways in which maintenance is organised and financed often mitigates against its ...

Green Maintenance for historic masonry buildings: an option appraisal approach

Purpose – Sustainability is well understood to encapsulate economic, environmental and societal parameters. The efficiency of maintenance interventions for historic buildings is no exception and also conforms to these broad factors. Recently, environmental considerations for masonry repair have become increasingly important and this work supports this growing area. The purpose of this paper is to give insight on how an option appraisal approach of “Green Maintenance” modelling for historic masonry buildings repair practically determine and ultimately substantiate the decision-making process using a calculation procedures of life cycle assessment, within delineated boundaries. Design/methodology/approach – Calculation procedures of the model enables an assessment of embodied carbon that is expended from different stone masonry wall repair techniques and scenarios for historic masonry buildings during the maintenance phase. Findings – It recognises the importance roles Green Maintenance model can play in re...

Conservation plan and “green maintenance” from sustainable repair perspectives

Purpose – It is well recognised that Conservation Plan has attracted attention to the maintenance of historic buildings; despite diverse array of issues, particularly associated with “Green Maintenance” concept and methodology and sustainable repair approach. The theory of these three concepts currently exists, but fails to be realised in practical integration. The purpose of this paper to ask why this failure is occurring and how it influences sustainable historic environment. Design/methodology/approach – The paper is composed of a critical review of existing literature and an argument built based on the concept of a Conservation Plan, “Green Maintenance” concept and methodology and sustainable repair approach for historic buildings. Findings – Despite the need of maintenance of historic buildings, this review suggests that a Conservation Plan often mitigates against its own association with “Green Maintenance”. Conversely, this could be improved by transforming the integration to be more pronounced in ...

Green maintenance for heritage buildings: paint repair appraisal

Sustainability encapsulates economic, environmental and societal domains. In order to conform to these domains, the efficiency of maintenance and repair of heritage buildings is no exception. Emergently, environmental considerations for sustainable heritage buildings repair have become increasingly important. The purpose of this paper is to present a decision-making process based on “Green Maintenance Model” – an appraisal approach based on life cycle assessment (LCA) of paint repair options for heritage buildings.,Calculation procedures of Green Maintenance model within selected boundaries of LCA enable evaluation of carbon emissions, in terms of embodied carbon expenditure, expended from paint repair for heritage buildings during maintenance phase.,“Green Maintenance” model could be understood as a carbon LCA of paint repair and has been recognized in reducing carbon emissions. Significantly, the model underpins decision-making for repair options for heritage buildings.,It must be emphasized that the calculation procedures of Green Maintenance model is not limited to heritage buildings and can be applied to any repair types, materials used and building forms. More importantly, this model practically supports environmentally focused conservation and promotes sustainable repair approach.,The implementation of Green Maintenance model highlights the efficiency of repairs options that may be adopted.,Green Maintenance shows that generated environmental maintenance impact from repair options relays the “true” embodied carbon expenditure contextualized within the longevity of repair and its embodied carbon. This will consequently allow rationale in appraisal of repair options.
