    Rethinking Smart Home Design: Integrating Architectural Perspectives and Technologically-driven Design Thinking within a Framework
    Dasgupta, Archi (Virginia Tech, 2021-10-25)
    Smart homes, equipped with sensing, actuation, communication, and computation capabilities, enable automation and adaptation according to the occupants' needs. These capabilities work together to build holistic spatial and living experiences for the occupants. Smart technologies significantly impact spatial experiences, making smart home design an architectural problem along with a technological problem. Nevertheless, smart home research focuses primarily on standalone technological solutions, where the spatial/architectural aspect is largely absent. We argue that addressing the technological aspects isolated from the spatial context leads to reduced experiences for the users/occupants, as this practice blocks the pathways to develop holistic and innovative smart home solutions. Hence, we focus on bridging the gap between architectural and technological components in smart home research. To this end, we studied the design of smart homes from related disciplines, i.e., architecture, human-computer interaction, human--building interaction, industrial manufacturing, and modular assembly. Our research used the triangulation technique to consult with subject matter experts (researchers, practitioners, and professors of related disciplines) to understand current design processes. We conducted ethnographic studies, focus group studies, and in-depth interviews and identified challenges and best practices for smart home design process. Our investigation recognizes a nascent research problem where the technological and architectural aspects come together in the design thinking of smart home designers. We expanded the scope of design thinking to include three primary elements of smart homes- embedded technology, architectural elements, and occupants' needs. This multidisciplinary and complex process requires a well-defined design framework to methodically address all the issues associated with it. Hence, we developed a user-centered design framework, ArTSE, through an iterative Delphi study to guide the smart home design process. ArTSE stands for "Architecture and Technology in Smart Home DEsign". This framework guides user requirements collection using HCI models, technology decision making, interaction modalities selection, the decision support system for schematic design, technology infrastructure development, and production of the necessary documentation. This framework is an evolution of the normative theory in the architectural design process that caters to the needs of smart home design. For defining implementation strategies, we applied the framework to a case study-- a smart reconfigurable space design project. Overall, we document different aspects of the smart home design process and provide a comprehensive guideline for designers, researchers, and practitioners in this area.

    Russell County Fairgrounds Commercial Building Conceptual Improvements and Master Tree Planting Plan
    Gilboy, Elizabeth; Jones, Kevin; Williams, Daphne; Dasgupta, Archi; Nautiyal, Divya; Stroud, Patricia; Thomas, Andrea (Virginia Tech. Community Design Assistance Center, 2016-08)
    Russell County, with a population of around 28,300, is considered “The Heart of Southwest Virginia.” The +/- 13-acre fairground site is located in Castlewood on Donnie Dean Drive. The fairgrounds highlight the Appalachian region’s heritage with its scenic rolling mountains as a backdrop. In sharp contrast to the beautiful views, the fairground buildings are outdated and in dire need of maintenance and upgrades so that they can continue to serve the changing needs of the community. The Commercial Building of the fairgrounds acts as the central venue for indoor activities such as beauty pageants, wrestling, music, arts and crafts, commercial vendors, political rallies, Boy Scout meetings, agriculture expos, and a community meeting place. The Russell County Fair Association (RCFA) and the Community Design Assistance Center at Virginia Tech worked together to develop a conceptual design to resolve these issues by developing concepts to upgrade the Commercial Building, the adjacent landscape, and a master tree planting plan for the entire site. This work was made possible, in part, through a $6,000 grant from the Virginia Department of Forestry’s Urban and Community Forestry Program. CDAC’s proposed concept for the Commercial Building expands the capabilities of the facility which can support economic growth for the fairground and Russell County.

    Towards a Unified Framework for Smart Built Environment Design: An Architectural Perspective
    Dasgupta, Archi (Virginia Tech, 2018-05-07)
    Smart built environments (SBE) include fundamentally different and enhanced capabilities compared to the traditional built environments. Traditional built environments consist of basic building elements and plain physical objects. These objects offer primitive interactions, basic use cases and direct affordances. As a result, the traditional architectural process is completely focused on two dimensions of design, i.e., the physical environment based on context and functional requirements based on the users. Whereas, SBEs have a third dimension, computational and communication capabilities embedded with physical objects enabling enhanced affordance and multi-modal interaction with the surrounding environment. As a result of the added capability, there is a significant change in activity pattern/spatial use pattern in an SBE. So, the traditional architectural design process needs to be modified to meet the unique requirements of SBE design. The aim of this thesis is to modify the traditional architectural design process by introducing SBE requirements. Secondly, this thesis explores a reference implementation of immersive technology based SBE design framework. The traditional architectural design tools are not always enough to represent, visualize or model the vast amount of data and digital components of SBE. SBE empowered with IoT needs a combination of the virtual and real world to assist in the design, evaluation and interaction process. A detailed discussion explored the required capabilities for facilitating an MR-based SBE design approach. An immersive technology is particularly helpful for SBE design because SBEs offer novel interaction scenarios and complex affordance which can be tested using immersive techniques.

    Transience and Permanence: An Architectural Dialogue
    Dasgupta, Archi (Virginia Tech, 2018-03-16)
    The American way of life is becoming increasingly transient in nature. But at the same time there is also the inherent need to have a sense of rootedness, the need for a place to call home, to belong. The current thesis is an architectural exploration of creating a dialogue between this duality. The approach is to explore a composite system, where modular prefabricated architecture is implemented in conjunction with traditional building practices. The idea is to address the transient nature and sense of belonging by combining the prefabricated modular approach with the site-built traditional approach. This study proposes that there are two types of spaces in a house that creates the overall spatial experience of a home. These can be termed as core functional spaces and more fluid or flexible spaces. Core functional spaces are bedroom, kitchen, bathroom, dining, formal living etc. Flexible spaces are more fluid in terms of function, for example – family living, lobby, lounge, connecting/common spaces etc. In the current thesis, core functional units are proposed to be developed as modular units. The reason is, because of their defined functionality they can be designed as basic modules. The modules would be prefabricated in a factory and transported to site. The modules themselves are composed of panelised systems. This allows for a flexibility in different permutation of layouts and enables adaptability of the house with changing family dynamics and other functional needs, thus addressing the transient nature of life. The fluid spaces are proposed to be built on site allowing greater flexibility in terms of dimensions, construction material and design. This type of space addresses the sense of permanence and rootedness as they are designed to be responsive to the site forces and define the unique characteristics of a home based on client’s unique requirements. Overall, the composite approach addresses transience and changing family demographics through the modular, prefabricated, core functional units. Prefabrication is adopted for saving time and expenses of construction. Assembly line techniques, grouping of similar tasks and use of skilled labour help in achieving that. The core functional spaces serve some basic purposes which is common for every house in general. So these spaces can be considered as repeating units and forms, and can be considered for prefabrication. For example, Kitchens, bathrooms or bedrooms can be treated as basic units and thus can be designed as prefab modules. Prefabricated, modular construction is rapidly gaining interest in the building construction industry. Implementation of modular construction improves the efficiency in production and safety in the working environment. This reduces the necessity to transport many skilled workers to the construction site. Prefabrication also helps avoid other adverse conditions like exposure to harsh weather or a hazardous environment, lack of water or power etc. On the other hand, the proposed composite approach addresses permanence through the site-built components. These components are responsive to different sites and different client needs. The fluid spaces are the spaces that do not serve any specific or basic purpose for the designed architectural piece to function as a home, but rather work as a space that binds all the core functions together. The fluid spaces ne the architectural experience of a house and how the core functions are coming together to form an architectural piece that one can call home. For example, common lobby spaces, informal living, corridors etc work as fluid spaces where all the functional spaces are connected. For different households, different family needs, the fluid space can receive the functional modules differently thereby defining the architectural space differently. This type of spaces can be designed using traditional on-site construction which provides the language of permanence and rootedness. Proposed modular units themselves follow a panelised construction, so it is easy to add or remove panels to support the different arrangements of modules around different types of site built elements. Thus the composite system supports the transience by providing adaptability and permanence by responding and being rooted to the site. The overall spatial experience created by the juxtaposition of these two systems and two types of textures is the focus of this thesis.
