3D Solutions for Shelter

INSPIRATION
Reaction-diffusion is a mathematical concept that de-scribes the process by which patterns and structures emerge in systems through the interaction of substances that undergo both reaction and diffusion. This concept, originally applied in the context of chemical reaction’s, has found applications in various fields, including biology, physics, and computer science. When considering human interaction, the analogy to reaction-diffusion can be drawn in the context of social dynamics and the emergence of patterns in interpersonal relationships. This project aims to foster those interpersonal relationships for: friendship, professional opportunities and diversity.

IMPLEMENTATION
Architecturally, we created open spaces, niches for conversation and interaction that are marked by Gray Scott’s simulation of reaction diffusion. A portion of the code is shown to the right. Using json, grasshopper/ Rhino, we were able to convert this simulation to a 3d surface which then was imported into our 3d model and converted to one of the concrete 3d printed walls. These act as symbols of where people can come together for a meal, a conversation or a any communal opportunity.

PRINT BED PARAMETERS
The print-bed parameters allowed us to design 6 residential units and a communal breeze-way, as shown in the diagrams on page 2. These units are approximatley 450 s.f each. Interior walls are drawn at 8” thick and exterior walls are drawn at 12”. We created an efficient unit that utilizes consolidated plumbing shafts/wet walls. As shown in the plans above, the kitchen and restroom are positioned along the demising wall, creating the opportunity for multiple units to utilize the same wet wall. The entries are carved out to create privacy and security.

PASSIVE SYSTEMS
Passive systems were implemented in the configuration and orientation of the units. East and West faces were minimized. The south side includes an overhand to avoid solar heat gain. On the north side, the overhang is angled upward to let in more light. All windows are operable, along with the garage door place at every entry. Ceiling fans were also placed in the space to promote air movement. The hvac system chosen is a ductless hvac split unit. This allows maximum ceiling heights and detailed control of the unit’s air temperature. We thought this system would be best, even with the more expensive up front install costs.\

SCALABILITY
The axon below shows the scalability of the 6 unit spread. Space and placement was carefully considered to not only create interaction but also privacy for when a person is inside their unit. Trees, plantings and lawns are placed in between each 6 unit spread to create moments of privacy for the users. The roof construction includes TPO, wood joists that support the roof. The roof is slope 2% toward to the north. This created an opportunity of rainwater collection on the north face. Sprawling lawns are placed in between the 6 unit spread for native, vegetable plantings, passive cooling and physical activity. Additionally, this solar ready roof spans 3,800 s.f. which gives ample roof for such configuration. A minisplit (ductless hvac) system will be mounted to the roof to work with the 10’-6” maximum height printing bed constraint.
