“…Many studies in different industries have focused on modeling decision-making and scheduling, such as building a decision support model for the maintenance and management of green areas [8], renovation scheduling to minimize user impacts in a building that remains in operation [5], and optimized maintenance and renovation scheduling in multifamily buildings [1]. For instance, Lee et al [8] propose a model using a decision support system to provide an appropriate maintenance schedule of green areas on campus by optimizing manpower.…”

“…Lee [5] also proposes an integrated model to search for a near-optimal schedule by minimizing the impact on users by relying on calculating the work zones and the time delay. For a group of buildings in an area, Farahani et al [1] carried out partial dynamic modeling to provide a cost-optimal maintenance plan by simulating several scenarios. However, these models have not found a solution for the long-term performance of the building since these studies do not propose a schedule optimization strategy attributed to the occupant convenience rate and the quality of the building.…”

“…For example, the maintenance of campus buildings is important because they serve many students during their education and serve as a workplace for teachers and staff. The main function of building renovations is to control deterioration and maintain optimal performance of each building component [1]. In the building life cycle, renovation is a prevailing activity carried out after the completion of the building construction phase.…”

“…Renovation design on campus does not rely only on technical necessities but also has to provide a strategy to achieve multiple objectives and often conflicting under resource constraints. Therefore, renovation of university campuses have three main elements: (1). Renovation projects are more difficult than new construction projects: The main characteristic that influences the complexity of renovation projects is the concurrent utilization of a building by both workers and users.…”

Renovation construction is employed for maintaining the long-term performance of buildings. For the occupants, the building users, renovation contributes to the acceptable levels of convenience and quality of the buildings. However, if the operation continues during the renovation for an area containing several buildings, such as a university campus, the impacts on the occupants are unavoidable. The complicated schedule plan is needed due to the various types of buildings and types of renovation under limited resources. The goal of this study is to build a model that can help the planners to make the renovation schedule plan. Taking a university campus as an example, the occupants’ convenience rate and the long-term quality of the building are analyzed in this paper. Based on the key attributes of building renovation, this study proposes a model integrating the genetic algorithm and simulation to provide the optimal schedule plan to the planners. The model is demonstrated by an application case of a university campus of 11 buildings remaining in operation. It helps the university maintain a good level of long-term performance of buildings.

“…In Italy, the residential stock is rather old, in line with the main part of European countries. In general, in Europe, almost half of the residential stock was produced before 1960 and is approaching the end-of-life stage, or have reached the end of its service life [1]. Analogously, a large number of infrastructures built in reinforced concrete have similar conditions.…”

Service life estimate is crucial for evaluating the economic and environmental sustainability of projects, by means—adopting a life cycle perspective—of the Life Cycle Cost Analysis (LCCA). Service life, in turn, is strictly correlated to maintenance investment and planning activities, in view of building/building component/system/infrastructure products’ durability requirements, and in line with the environmental-energy policies, transposed into EU guidelines and regulations. Focusing on the use-maintenance-adaptation stage in the constructions’ life cycle, the aim of this work is to propose a methodology for supporting the “optimal maintenance planning” in function of life cycle costs, assuming the presence of financial constraints. A first research step is proposed for testing the economic sustainability of different project options, at the component scale, which imply different cost items and different maintenance-replacement interventions over time. The methodology is based on the Annuity Method, or Equivalent Annual Cost approach, as defined by the norm EN 15459-1:2017. The method, poorly explored in the literature, is proposed here as an alternative to the Global Cost approach (illustrated in the norm as well). Due to the presence of uncertainty correlated to deterioration processes and market variability, the stochastic Annuity Method is modeled by introducing flexibility in input data. Thus, with the support of Probability Analysis and the Monte Carlo Method (MCM), the stochastic LCCA, solved through the stochastic Equivalent Annual Cost, is used for the economic assessment of different maintenance scenarios. Two different components of an office building project (a timber and an aluminum frame), are assumed as a case for the simulation. The methodology intends to support decisions not only in the design phases, but also in the post-construction ones. Furthermore, it opens to potential applications in reinforced concrete infrastructures’ stock, which is approaching, as a considerable portion of the building stock, its end-of-life stage.
