Sustainable Built Environments Senior Capstone Project / This research examines the viability of tire masonry units as a material for exterior walls in residential construction when compared to other alternative materials (straw bales) and traditional materials and methods (wood frame construction). This comparison is executed via a matrix which assigns scores to each material based on their performance in the following criteria; energy efficiency, human health, environmental health, structural soundness, and monetary costs. Tire masonry units have been offered up as a solution to both tire disposal issues that are detrimental to the environment and the problems posed by the need for virgin materials in housing construction. This research concludes this is not the case, and the use of tire masonry units fails to provide solutions for either of these pressing issues.

Earthships are buildings which are constructed almost entirely of recycled materials and are built to be almost totally self sufficient through the recycling of rain water, the recycling of solar energy into electrical energy, passive solar techniques and sometimes the recycling of wind through turbines, also into electrical energy. This thesis draws out and demonstrates the logic that Earthship architecture emerges from and generates amongst its inhabitants. This logic, it is argued, can be characterized as containing elements of the baroque and Neo-baroque. It is a logic of following and interfacing the elements (earth, sun, wind, rain) that folds them into itself. In such a space it is impossible to delineate any strict division between the inside and outside of a house. The inside becomes a node, interval, or point of passage of the outside and domestic life emerges from a complex and dynamic rhythmic arrangement with the outside. Such a space emerges from and generates a new sense of nature as cycles, flows, and interconnections which are fundamentally inseparable from architecture, technology or domestic life. This thesis also argues that to properly understand Earthships it is necessary to draw out the sense of historical and natural catastrophe that has impacted their origin and present incarnations.

Architecture, as a discipline, has the potential to serve as a catalyst for cultivating an awareness of our intrinsic connection to the Earth and the broader universe. However, in the contemporary world, architectural practices frequently tend to alienate us from the natural environment, compelling many of us to inhabit indoor spaces reliant on centralized utility systems. This reliance, in turn, exerts significant stress on the Earth's ecosystems. The essence of architecture should instead lie in its capacity to engage with the surrounding natural elements, including the sun, wind, earth, and rain, thereby prompting individuals to acknowledge their geographical and planetary context. By harnessing these natural forces at the local level, architectural structures could autonomously provide their occupants with essential resources such as energy, water, and sustenance throughout the year. This thesis embarks on an exploration of the feasibility of integrating these principles of passive design into architectural structures, with the overarching goal of imparting experiential learning opportunities to the broader public. Through this endeavor, architecture can transcend its conventional role and emerge as a conduit for disseminating knowledge and awareness about sustainable living practices. Ultimately, this reimagined role for architecture can play a pivotal part in catalyzing the ongoing human evolution towards enhanced health and resilience, both as individuals and as a species. / Master of Architecture / Architecture should make us aware of how we are connected to the earth and by its extension, the universe. In today's world, it often closes us off from nature instead. Many of us are plugged in to an indoor culture that relies on centralized utility infrastructure to sustain, which often puts great strain on the natural environment. By interacting with surrounding natural phenomenon such as the sun, wind, earth, and rain, our buildings should remind us of our geographical and planetary context. By gathering these natural forces local, a building could supply its inhabitants with energy, water, and facilitate food production year round. This thesis aims to explore how a building could demonstrate these principles of passive design to the general public by using architecture as a vessel for experiential learning. This is the role Architecture can play in the process of human evolution towards becoming a healthier and more resilient species.

In an age where the sharing economy has proliferated as a preferred means of travel in the tourism industry, and the accommodation sharing platform Airbnb has risen to the forefront, there is much criticism and discussion about the need for such nascent platforms to operate in alignment with sustainable development. Currently, economic benefits for the host and guest lie at the core of Airbnb’s sustainability appeal, while few concrete steps have been taken to advance environmental and social values. Many have proposed a green rating system and sustainability-oriented search filters as a means to propagate these values and catalyze a necessary paradigm shift within the sharing economy. Through the lens of green architecture and construction, this study analyzes the extent and manner in which sustainability features and amenities are promoted by hosts on Airbnb in the high-desert mountain town of Taos, New Mexico. This case study approach selects and intriguing destination that is not only characterized by a long history of earthen building traditions by the Tiwa people, but was also the birthplace of the world-renowned, off-the-grid Earthship concept. An analysis of all active Airbnb listings was compared with a more targeted analysis of off-the-grid listings to reveal that hosts more often than not frame their sustainability features and amenities in terms of visitor comfort, convenience, and enjoyment. For instance, the valorization of earthen adobe building for its authenticity and cultural appeal in lieu of its energy efficient and natural qualities. This indicated a high level of unexploited potential, wherein hosts could enhance their listing’s sustainability appeal and educational value through reframing these features to potential guests, and off-the-grid listings could benefit from implementing and promoting sustainable practices and emphasizing the local culture. Most importantly, after quantitively analyzing the features that arose, this study assembled the content basis for a theoretical green rating system and sustainability search filters that could be applied to Taos as a localized system, or merely provide insight to other destinations and the Airbnb platform as a whole.
