ARCH2102 Design IV - Integrative Design / Spring 2022
Instructor: Katharina Kral
The proposed project site is in Seneca Falls, New York, a historically significant location known as the birthplace of the women’s rights movement and situated along a branch of the Erie Canal. The town has experienced a population decrease of -9.37%, largely due to the outmigration of young residents. To create new opportunities for community gatherings, the proposed community library aims to weave together ancient memories and modern experiences.
The community library design incorporates two distinct structural systems: a traditional brick dome and a free-form brick vault. The library programs are visualized as a series of brick domes arranged in the plan configuration, with the free-form brick vault serving as a bridge connecting different programs and as the primary medium for book collections. The form-finding and structural detailing process is informed by environmental performance analysis, with a focus on passive design strategies to maximize the thermal performance of the brick material and dome form. Overall, the community library design aims to honor Seneca Falls’ history while providing a modern space for learning and gathering.

Study models for brick vault’s form-finding (Clay, paper, and 3D-print resin)
The roof orientation is switched from southwestern to northeastern to obtain consistent and diffuse daylight.
Southwestern facades will still be the best location to place PV panels.
PV panels are designed as an additional layer on the facing brick. The density of PV panels will vary based on the orientation. southwestern facades will have more PV Panels.
To create a well-daylight space (illuminance target:800-1800), southern opening size need to reduced and northern openings need to be large. Original large, eye-level wiindow is reduced and move up. It could avoid more direct sunlight for improving both UDI and glare.Adding fixed shading on arch windows; Adding dynamic shading on rectangular windows(for different program demands).

ARCH2101 DESIGN III - “LIGHTNESS” / Fall 2021
Instructor: Roz Barr
The design of the project explores the concept of “in-between” moments in our daily life, symbolized by the name “Tri,” which represents the transition between different states. This discourse of “tri-status” is evident in the transition between workplace and home, the creation of “personal corners” for the three family members, and the relationship between inhabitants and nature.
The project also places emphasis on the concept of “lightness,” achieved through optimized fenestration strategies and facade materials choices that balance light performance and privacy. By carefully considering the balance between light and privacy, the design aims to create a harmonious and inviting space that is both functional and aesthetically pleasing.

ARCH3101 DESIGN V - “PUBLIC | SERVICE” / Fall 2022
Instructor: Sydney Maubert
This project seeks to challenge the Lincoln Center, a symbolic space of power and authority, by reconstructing the abandoned areas between its enormous constructions. By questioning whether the gigantism of architecture serves culture or authority itself, the design aims to reconstruct the space in a way that brings back the potential San Juan Hill culture and the neighborhood’s sense of place.
The design incorporates a timber-mesh construction as a threshold that intrudes into Lincoln Center. By rearranging the space’s vertical and horizontal divisions, the reconstruction aims to reconcile the enormous scales of Lincoln Center. The timber frame systems serve as the foundational approach for a dynamic threshold, while the meshes serve as a public medium for displaying the neighborhood’s artworks, propaganda, and statements. Through the deconstruction and reversal of spatial and political relationships, this project aims to explore the potential of architecture as a form of undemonstrative rebellion.

A WINDOW-TO-WALL RATIO ESTIMATION FOR ENERGY MODELING
Group Work with Jiayu Su, Zhisui Ren, and Tony Liu
Instructor: Timur Dogan
This project aims to investigate the optimization of methods for collecting window-to-wall ratio data of existing buildings on an urban scale for future building retrofits. The study employs multi-disciplinary methods, including the generation of photogrammetry models using drone-captured photos and the utilization of machine learning techniques to automatically identify windows on building walls.

Based on the existing research of “Structure-aware Building Mesh Simplification,” we could reconstruct the mesh into a clean, effective building model for energy analysis.
We expect this methodology could be applied to urban-scale building data collection and environmental analysis. It optimizes the currently available methods of energy modeling for building retrofits and aims to contribute to a sustainable future.

This project aims to create an environmental-friendly, low-budget, and easy-to-assemble house that would help promote the equality and sustainability of the construction environment. Located in southeast Asia, the buildings are mainly constructed using bamboo, a local material that is easy to get and manipulate. We learn from the traditional local bamboo building and develop a modular unit, which could later be combined in different ways to accommodate for different sites. Users could choose different facade panels with embedded furniture to construct their houses.
Bamboo lives in symbiosis with the landscape and surrounding nature. At the same time, as a natural material, bamboo could be easily disassembled and reused or recycled. Together with the photovoltaic panels, rainwater collection system, and roof overhang to block summer sunlight, both the operational and construction energy is reduced.
