| summary |
This paper aims to investigate the relations between architectural quality and financial feasibility of the design for constructing a sustainable environment. how is it possible to make the architect a protagonist of the design decision-making process, in which the financial impact on the final result is often most valued? The design process is often the stage of conflicting processes, and in particular, most requirements aiming at design sustainability usually collide with the financial plan and investment feasibility. How can the architect manage these conflicting requirements at early stages of the design process and keep track of their impacts as the design progresses in detail?
During the design process, the architect is responsible to generate options seeking to meet the objectives of the stakeholders, while balancing multiple criteria such as sustainability requirements, cost, aesthetics and other. The set of design objectives must not impair the other qualities of the building or subjugate them to the final cost. In this way, we propose a digital tool to assist the architect, based on customer feedback, in different stages of the architectural project. Considering that financial feasibility is an essential design objective, the architect can operate a central role in this process, by balancing design decisions. The method consisted of (1) definition of the calculation models, (2) computational implementation of the tool (composed of a BIM modeling tool and an evaluation module), and (3) carrying out the case study. Initially, we present the framework, with an approach to the different stages of the project, systematized in LOD. Then, the different calculation models were implemented in a BIM/VPI environment, following a modular structure. We show a case study based on a housing project. Finally, we implemented the tool in a professional environment.
Once a design program and a maximum investment value is defined for that program, the tool allows to confront construction cost and sustainability objectives (e.g.: designing a nZEB - netZero Energy Building) along the design process at different levels of detail. The flowchart for our BIM/VPI algorithm is presented and discussed in regard to its possible contributions to the production of more sustainable environments. |
