A B S T R A C TA great deal of interest in off-site construction has been remarkable over the last decade. However, building on the rooftops of existing building has not been given a significant importance as a subject of research, despite its dependence on off-site construction and prefabrication. Thus, this paper develops a novel conceptual framework to support a multidisciplinary decision making for selecting off-site prefabricated constructional system for roof stacking. The multidisciplinary approach includes each of safety, logistics, cost, time, environmental impact, and quality of construction as major criteria in the decision making process. This paper is the outcome of an exhaustive investigation of more than 136 roof stacking projects built during the last 20 years. The development of framework is supported by a feedback validation loop based on semi-structured interviews with experts in the field of roof stacking and off-site construction.

“…The choice of lightweight construction has been put forward as an objective based on a wide survey conducted among building engineers who have expertise in building on rooftops around Europe. The results of this survey show that the weight of the construction is an essential criterion when choosing the optimum combination of building parameters [32].…”

“…Although the scientific community has proposed a numerous of multi-objective optimization methods, there are a limited number of studies that consider the implications of roof stacking on the reduction of carbon emissions and energy use of existing buildings [6][7][8][32][33][34][35][36]. Generally, it is argued that by providing more compact cities, it is possible to reduce the energy use on the building and transportation scale [37][38][39].…”

The interest to find cost-optimal zero-energy solutions for building, using multi-objective optimization, has risen dramatically over the last decade. Accordingly, several studies have been carried out, proposing new methods and tools. None, however, has introduced a simplified approach that is viable by a broader range of users. This study addresses this lack, offering a methodology that supports the decision making process on cost-optimal zero energy building, using a novel approach, namely Multi-Objective Parametric Analysis (MOPA), rather than optimization algorithms. This study adds to the domain of roof stacking construction by setting the weight of construction as a third objective. The current methodology is applied to a newly developed theoretical Reference Building (RB) for a Belgian passive roof stacking house. Different options of the building's superstructure components (walls, roof, and windows) have been examined. MOPA follows three consecutive steps: modeling setup, parametric simulation, and ends up with evaluation and selection. The results show cost-optimal zero-energy and lightweight packages of design variables for the building envelope.

“…Dind, Lufkin and Rey (2018) presents a multicriteria evaluation of the architectural concept to design timber construction systems for vertical extensions of office buildings. According to Amer and Attia (2019), the selection of optimum roof stacking construction method is merely based on subjective evidence supported on architects' or owners' requirements. Therefore, they identified, categorized and ranked 37 influential criteria behind the selection and decision making on roof stacking methods, based on sustainability triple bottom line, i.e.…”

The initial premise of this research is that the relative efficiency of refurbishment solutions with architectural membranes needs to be measured in order to allow its comparison with conventional solutions, helping decision makers to select the most efficient solutions. The evaluation of this efficiency depends on economic features, but also on functional, technological and environmental ones. This study presents a model to solve this problem, using decision trees, multicriteria decision-making methods (SAW and AHP) and a sensitivity analysis. The selection of the criteria and the assignment of the corresponding weights was attained through an expert group survey for a baseline scenario, aiming maximizing functional performance (such as energy savings) and minimizing employed resources (materials, costs, etc.). The most efficient refurbishment solution among the set of alternatives was reached using the developed model. The methodology was applied to a case study-an old building from the 19th century, located in Portugal, which was refurbished with a vertical extension. The result reveals that the proposed model is successful and illustrates the potential of this evaluation methodology to compare and quantify the efficiency of a series of different lightweight constructive solutions. It also underlines the advantages of using lightweight building technologies, especially with architectural membrane materials, in building refurbishments.
