Parametrical design tool and the production of technical data for superadobe domes

Abstract

The interest in earthbag dome construction (also known as earthbag or superadobe) has been increasing as world consciousness develops to achieve the planet’s equilibrium for sustainable living. The main objective of this research is to develop a parametric tool to help architects modeling virtual earthbag domes from ideation to construction phase. This challenge has been addressed by adopting an experimental methodology that explores parametric generative design with the use of a visual programming language (VPL). In this paper we present the development of a tool for the ideation level including features that allow for the calculation of material quantification. Even thought, the tool does not work in a Building Information Modeling environment, the generative model outputs technical information to support construction, namely material quantities. The usability of the tool was validated by a random international sample of experts.

“…Outro ponto forte no uso do BIM-VPL diz respeito a verificação de conformidade das construções com base em regras e requisitos pré-definidos (7 artigos) e a análise de eficiência energética e desempenho, principalmente desempenho térmico (5 artigos). No primeiro, o VPL é utilizado juntamente com o BIM para verificar se os projetos e construções atendem aos requisitos normativos, requisitos de projeto, do cliente, entre outros [9], [10], [11], [12], [13], [14], [15]. No que diz respeito à análise de eficiência energética e desempenho, um dos estudos buscou a criação de uma estrutura de otimização do desempenho visando à minimização do consumo de energia [16].…”

A study of the geometry and structural performance of superadobe domes

“…o The algorithm receives a dome's parameters (section 6.4.1, Figure 6-31 for example) and produces an output screen (for example, section o As before, the central idea of such algorithm is that it estimates the greatest (limit state) forces and stresses that could possibly form inside the dome given the hypothesis that the material is stiff, perfectly transmitting stress without deformation. with the features and ideas of a tool such as CICERO [57], which calculates material quantities and produces building visualizations from a set of input parameters using computational thinking, also integrated with the assessment tool for structural safety of the designed building (calculating forces, stresses and possible failure modes for each ring and the trajectory of a hypothetical resultant force [53]), is a worthwhile effort to control and automatize the design of Superadobe domes.…”

“… Chapter 8, proposition 9, is a medium term effort, that seems suitable for a technology with an adjustable-parameter geometry and a homogenous construction pattern: To create a program that finds missing geometric parameters of a dome having preset a desired combination of functional geometric dimensions (solving systems of inequalities, see section 5.7), integrated with the features and ideas of a tool such as CICERO [57], which calculates material quantities and produces building visualizations from a set of input parameters using computational thinking, integrated with an assessment tool such as the one developed in this thesis, which, given more refinement, could predict structural safety of a designed building (calculating forces, stresses and possible failure modes for each ring and the trajectory of a hypothetical resultant force [53]). It is a worthwhile effort to control and automatize the design of Superadobe domes.…”
