# Parametric Integration of Multiple Criteria from a Cultural Heritage Perspective
## 2 Materials and Methods  
We will outline the methodology creation process based on the \"design thinking\" methodology:  
1. Empathize: through several activities of space and territory recognition carried out by researchers and the Misak community, providing explanations of the cultural heritage linked to space, symbolism, and lifestyle, so they can comprehend their cosmovision and highlight three key elements. 2. Define: the starting point is the demands of the Misak members. The first key is the spiral, which represents how a baby's life spins from the moment of his birth until the day of his death. Evidence of this is that the Misak members don a traditional hat with a spiral-shaped knitting detail, shown in Figure 2--described in detail in Section 3.1.1. The second key is the presence of the fire that serves as a metaphor for how people and their possessions interact. The third key component is the importance of natural materials in their architecture. Besides these previous key components, other characteristics need to be considered. The location of the site was chosen because it is at the summit of a mountain, putting people on a site that could be easily recognized from far away, and transforming its meaning into a building of reference for the community. The location also offers a beautiful view of a breathtaking landscape. The structure serves as a gathering place for ADA members of the Misak Community, including blind or deaf or those who are unable to walk. 3. Design: the geometric and mechanical characteristics of the Guadua (_Guadua angustifolia_) serve as the primary inputs for the algorithms developed for this research. Thus, we find a geometry using a specific material instead of using materials that are recommended for a group of geometries. 4. Prototyping: in which the parameters are transformed into algebraic design ideas. The tool used for parametric design is the graphical algorithm editor Grasshopper, which is tightly integrated with 3-DRhinoceros. The first consideration is the maximum slope permitted by the Colombian Code, which is 10% [23]. The second consideration is the space which must have a fireplace that can be placed inside it, with respect to integrating the cosmovision of the Misak Community. During the form-finding phase of the roof morphology, we considered the design of two variants of a double-curvature surface. In the first variant, called \"Variant A\" from now on, freeform surfaces were contemplated for the possibility of deforming the rods within the elastic limit. In the second variant, called from now on \"Variant B\", there are constant-slope surfaces, which do not require the Guadua (_Guadua angustifolia_) to be bowed, considering that only linear structural elements can be used. Once the morphological variants were defined and the material data were integrated into the algorithm, the next step on the design stage transformed the geometry into a structure. This associates architectural intentions--in relation, for example, to environmental parameters such as luminous flux--with structural constraints and the feasibility and ease of construction on site. The final structure must follow the usual dimensioning criteria for a structure meant to be open to the public: the strength and rigidity of the structure must be those of a building considered safe by the standards in force in Colombia. To check that displacements remain under control and stresses below a certain threshold, we use RDM7, under a combination of normal loads--the serviceability limit state--and low probability loads (the ultimate limit state). 5. Testing: the stage where the prototype design, optimization and geometry evaluation processes are carried out. Information used as input for the daylight algorithm is related to the site location. It is situated at a height of 2.800 m (9.186 foot) above sea level in Silvia, Colombia, which experiences a tropical climate.
