Grover and C. Grover, 2015;Rodi et al, 2015).…”

“…Locational obsolescence is where an area suffers from devaluation. It reflects the fact that part of the value of any property is determined by the neighbourhood in which it is located (R. Grover and C. Grover, 2015). Locational obsolescence occurs when buildings located within a particular area suffer from devaluation because the area is seen as less attractive by current or prospective occupiers (Pinder and Wilkinson, 2001).…”

“…Therefore, obsolescence is a serious threat to built property, and necessary measures must be taken to avoid building obsolescence or to mitigate this problem. Prevention can be the most effective and efficient approach for avoiding obsolescence (R. Grover and C. Grover, 2015). Identifying building obsolescence and its different types can be the first step in the preventing approach.…”

PurposeObsolescence is a decline or loss of utility of an object, building or product. Different types of building obsolescence decrease buildings’ utility and shorten their service life. The purpose of this paper is identification of building obsolescence types and the relevant factors that affect buildings to become obsolete. It is also intended to categorise building obsolescence types to provide a contribution towards increasing building service life and delivering sustainability.Design/methodology/approachA systematic literature review is applied to conduct this research. It follows five steps: (1) formulating the research question; (2) locating studies; (3) selecting and evaluating relevant studies; (4) analysing the findings; (5) reporting and making use of the results.FindingsVia this study, it is revealed that there are 33 types of building obsolescence. They are clustered in 10 categories regarding their conceptual and causing aspects and are presented based on their recurrence in the literature. According to the findings, economic obsolescence (including economic, financial and market obsolescence types) and functional obsolescence (including functional, use and utility obsolescence types) are the most remarkable categories.Originality/valueInvestigating the literature makes it clear that building obsolescence types have been studied intermittently with infrequent profound exploration of the relationship between them. This paper presents a comprehensive identification of building obsolescence types and introduces obsolescence categories that classify connected obsolescence types. It is a new framework for further studies on building obsolescence to find more effective prevention strategies to mitigate social, economic and environmental consequences of building obsolescence.

Depreciated Replacement Cost: Improving the Method Through a Variant Based on three Cornerstones

Within the scope of real estate appraisal, the Depreciated Replacement Cost method is mostly seen as a solution of last resort, when no other option is available. Nonetheless, it is ever more useful in addressing various estimation needs. In its basic formulation, the method suffers from several simplifications that lead to rather rough results. Here we try to go beyond these limits. To this end, we propose a variant based on the following three cornerstones. The first is the partition of the replacement cost into its fundamental components, at least according to three cost items: building structure, finishes, and installations. The second cornerstone is the formulation of different depreciation curves for each of the cost items mentioned above, by processing distinct data on useful life and residual life. Finally, the third cornerstone is represented by the definition of a complex depreciation function to take into account both the original useful life of the construction and its lengthening due to partial or full refurbishments.

Obsolescence occurs when system elements become outdated, and it leads to operational, logistical, reliability, and cost implications. In the U.S. military, this problem is a result of the U.S. Department of Defense's (DoD) departure from Military Specification (MILSPEC) standards in 1994 and transition to the use of Commercial Off the Shelf products. Obsolescence costs the DoD more than $750 million annually. The current risk management tools for obsolescence are based on a quantitative approach that uses cost optimization, and expert judgment is not used as a critical criterion. A review of the literature has revealed that during the design phase of technological systems, there is limited knowledge and a lack of training associated with mitigating obsolescence, and multicriteria decision-making (MCDM) methods are not currently used to mitigate the risk of obsolescence. Thus, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS, which is a MCDM method) and Monte Carlo simulations are proposed as the foundation for this work. This paper adds to the methodology by introducing an expert judgment criterion. A case study was conducted using military and civilian experts. Expert validation showed that the TOPSIS model successfully identified the best system for mitigating obsolescence. This model can be used by system designers and other decision makers to conduct trade studies in obsolescence management.
