iv The world is facing two fundamental problems. energy. The second problem is increasing greenhouse gas emissions that are directly resulting from our energy consumption. The primary greenhouse gas in question here is carbon dioxide produced from the burning of articles and studies that carbon dioxide is directly linked to rising atmospheric temperatures. Buildings represent Many architectural theses and treatises have been written advocating architecture that is more and processes as necessary steps towards solving the global warming crisis. With the threat of global warming looming, everyday architecture must go through a transformation. architectural gems. Instead, sustainable architecture should become a commonplace condition in the built environment. In order to achieve this, we need sustainable architecture that not only addresses the environmental issues but also pays for itself and pays the building owner for taking on such a task. To answer this need, I intend to design a mixeduse multifamily building that exists in the environment as a living system. As all living things, it must function utilizing the resources available in that environment. It must have a practical and economically viable onsite energy production and storage methodology that is ARCHITECTURAL SYMBIOSIS ABSTRACT Tim Kimball
v environmentally benign and takes advantage of freely available natural resources. It must react to changes in the environment to better manage its resources and it must be able to store resources for later use. Lastly, it should foster sustainable living practices of its occupants. By building in this way, architecture can take on a new role as symbiant rather than parasite in the environment, producing its own pollution free energy and clean water. Each building acts as a life support system for its inhabitants but is also part of a macro scale biosphere. If resources are managed carefully, an exportable energy surplus can be generated provides an economic directive to adopt sustainable practices.
1 [A designer is] an emerging synthesis of artist, inventor, mechanic, objective economist and evolutionary strategist. Buckminster Fuller THESIS STATEMENT
2 It is absolutely imperative we understand that human beings do not exist in a vacuum. We are, like every other living organism on this planet, completely dependent on the quality of the environment that we inhabit. It is incumbent upon us to respect and maintain the cradle of humanity since we now wield considerable power to alter the landscape. We can wield that power recklessly, without regard to our neighbors and without any regard to future generations, or we can wield that power responsibly and effectively while still providing for our immediate needs. Some believe that there is a choice that must be made between human needs and protecting the environment. This is a false choice. We really can do both. Architects are routinely The evidence is very clear that human activity is having an effect on the overall health of our ecosystem. Figure 01 Kyoto Carbon percentages

4 Since buildings are responsible for at least 25% of this offer some possible solutions. We could try to build new architecture that does less damage to the environment. We could try to upgrade all of the existing buildings to be more sustainable. But, that pays modest dividends and upgrading everything is nearly impossible. (Not to What if people started building structures that can offset some of the damage thats currently being done on a new role as symbiant rather than parasite in the environment, producing its own pollution free energy and clean water, wherein each building acts as a life support system for its inhabitants but is also part of a had a building type that came with a viable business It is important to recognize that every building has an economic life. Our clients usually have economic motivations for the buildings that they ask us to design on their behalf. Architects must consider these economic realities and have an understanding of the economic environment during the earliest design phases. Only then can you begin to deliver solutions for your client that are holistically designed and economically viable. My approach is to examine the underlying forces that drive our current unsustainable behaviors,
5 which are primarily economic, and ask if it might be possible to use those same forces to achieve a new set of objectives. Students of Aiki Jujutsu, a traditional Japanese martial art, understand that when dealing with overwhelming force, its best to avoid direct opposition. The basic tenet of Aiki Jujutsu is to never oppose force with force but to redirect and utilize the power of the attack to overthrow the enemy with their own strength. With this in mind, the designer has a strategy for promoting sustainable architecture and living practices. The designer can harness economic forces to further We have to exploit the resources available to us locally and produce a marketable product. We must design our architecture to support and enhance that effort. In Florida we are fortunate to have a very potent natural resource available to us. That resource is solar energy. Traditionally, Floridians expend substantial amounts of energy attempting to combat the effects of the intense solar radiation that we experience here. But, we could be taking advantage of this resource instead. Each new building that is built could add to its program the function of micro utility, meaning that they could have enough solar energy output to provide some carbon free power to its neighbors and receive begin the shift from a carbon producing paradigm to the

7 Project Selection I have always believed that if you truly care about the environment then you should live in the city. Urban spaces make the maximum use of the land that we occupy as a species. This allows more of the environment to remain wild and support animal and plant life, which in turn supports human life. The density of the urban environment allows for minimized travel distances, which translates into lower energy usage as people conduct their daily lives. development is the mixed-use building. The mixednecessary to create urban communities that are vibrant, exciting and draw people into the urban core. In light of these facts, and in attempt to live up to the ideals I have outlined, I am proposing a mixed-use residential traditional components of residential space, retail and/or Cultivation Habitation Micro-Utility This new mixed-use typology can go into existing suburban neighborhoods surrounding an urban center
8 to create a cellular network of independant nodes producing carbon free energy and providing some of that energy to the neighboring legacy buildings while producing various marketable agricultural products that are grown on site as well. Problem Statement The design challenge that I have set forth in this thesis project is to develop a residential mixeduse building that lives off of the land. The interplay and overlapping of different building functions will be form. The local climate presents special problems and opportunities in relation to the creation of spaces that allow for maximum personal comfort while using minimal resources. Water use and treatment will also present unique challenges. Figure 04 Cellular Diagram

10 Design is a learning experience. So my agenda is to Olive1:1 CASE STUDIES
11 Case Study 1: Earthship Biotecture This architectural movement was started by architect Michael Reynolds. The primary aim of the Earthship design is to be a self-sustaining capsule like a sailing vessel. The Earthship operates utilizing freely available natural resources that exist in the environment. Built almost entirely out of recycled materials, including discarded tires, bottles, cans and other reclaimed building materials, the Earthship conserves natural resources by extending the useful life of materials that would otherwise be discarded. The tires are used as forms for the rammed earth structure which is a hallmark of the Earthship movement. The massive nature of the rammed earth walls serves as a thermal mass that helps Figure 05 Section, rainwater storage Figure 06 Section, passive design features
12 to regulate internal temperatures within the structure. harvest rainwater and store it on site. Potable water is Instead, a sophisticated system of graywater which employs constructed wetlands ensures that water is used no less than four times before it exits the structure. The constructed wetlands serve a dual purpose. They particulate matter before use in non-potable applications and they provide a planting area that can be utilized for the cultivation of food for use by the occupants. Figure 08 Banana trees cultivated in biocell
13 Lessons Learned The Earthship design is successful in the climate that it was originally designed for, which was a dry desert climate. However, thermal massing is not appropriate for a humid subtropical climate because unlike the desert climate, daytime and nighttime temperatures do not vary widely and because the everpresent humidity serves as an insulator which prevents proper thermal transfer. The geothermal constant could be utilized to aid in temperature regulation through other techniques such as ground source heat pumps in place of traditional HVAC. Rainwater can be harvested and utilized more patterns allow. By implementing passive strategies that are energy usage can be realized. Alternative energy sources, such as wind and solar, become feasible when energy demands are reduced through passive strategies. cultivation of some percentage of food resources required by the buildings occupants.

Lessons Learned Combining uses and layering them in a creative fashion can create opportunities for green space in an urban environment. Utilitarian elements can be screened with more aesthetically pleasing components creating a more harmonious design. Opportunities for community can be realized through creative spatial arrangements.

18 Case Study 3: Big Dig House Architects: Single Speed Design Location: Lexington, MA, USA Program: Private House Completion year: 2008 Constructed Area: 353 m 2 The Big Dig House is an artfully designed singlefamily residence constructed from salvaged components left over from Bostons Big Dig project. The steel and concrete components are designed with much higher carrying capacity than standard residential construction. This additional carrying capacity allows for substantial rooftop gardens. Because this building was constructed Figure 20 Ext. Perspective, Big Dig House Figure 21 Raw materials, Big Dig House

20 Figure 25 Interior perspective, Big Dig House using standardized industrial components, the architects planned the building as if it were a pre-fab system. Using repurposed steel structural members and roadway panels, the structural framing was completed in only 12 hours instead of an estimated two weeks for standard framing. This undoubtably represented a substantial savings in construction costs. The idea of using standardized erector set components leads to the possibility of designing structures with what the architects call on thier website Strategic front end planning wherein the components of a structure are designed for the eventual possibility that it may be dismantled and those elements reused in another construction project. This conserves resources along with the embodied energy within the materials.
21 Lessons Learned Standardized components can be arranged to create aesthetically pleasing spaces. Modular, prefabricated components can save time and money in construction. Reused components save resources and energy. structures can be designed to be easily dismantled Figure 27 Exterior perspective, Big Dig House Figure 26 Construction Phases

Tampa has an extended growing season which will also be an advantage for this project as well. of paramount importance. It can make the difference between a project that is merely good and a project that is spectacular. But in this particular case, site selection isnt as critical because this project will be existing neighborhood context. I want this to be something that can be repeated somewhere else, so my selection criteria will be driven by principles of sustainability and by suitability for the particular building type, which in this case is residential. Primary characteristics under consideration: Proximity to the urban core As stated before, it is preferable to have a site that is close to the downtown area. This minimizes travel distances for the occupants when accessing workplaces or the amenities that the city has to offer. Public transportation becomes a more viable option when travel distances are short. All of these things translate into lower energy use as people conduct their daily lives.
25 Access to sunlight Unblocked southern exposure is required because solar radiation will be collected as a primary energy source. There will also be some light agriculture being done on site, which will require sunlight as well. Non-virgin land Urban sprawl is responsible for a reduction in natural habitat for many plant and animal species that we rely upon to maintain a healthy ecosystem. Therefore, it is preferable to recycle land that has already been transformed for human use.

31 Site Selection The site that I have chosen lies between 7th Avenue and Oak Avenue on Morgan Street. This site is in an old Tampa neighborhood called Tampa Heights. 7th Avenue is one of old Tampas characteristic brick lined streets and it leads straight into the heart of Ybor city which lies about 10 blocks to the east. Tampas central business District lies to the south about 10 blocks. In much of the neighborhood, mature oak trees line the streets and provide much-needed shade which creates a very walkable neighborhood. There Figure 41 Site boundries Figure 40 Site location overview

Riverfront lies to the west of the site. Since Tampas central business district is surrounded by water on the eastern, western and southern edges, future growth will tend to be towards the north. Ybor citys growth has been primarily to the south but space is limited in that direction so future growth will probably be to the west along Palm and 7th Avenue. The selection of this particular site is designed to take advantage of the eventual merging of Tampas central business district and Ybor city as well as Tampa Heights eventual redevelopment. The approximate dimensions of the site are 222 x 295 with an area of approximately 65,490 s.f. and consists of 6 RS-50 lots, each approximately 50 x 100.

35 The focus of my research is to identify and evaluate various technologies that may be used to achieve the aforementioned goals of: Generating an excess of carbon-free power Zero discharge sewage On-site food cultivation In nature, nothing goes to waste. The refuse of one organism becomes the fuel for another organism. A sort of Yin-Yang relationship is often formed wherein one organism cannot exist without the other. We call this symbiosis. As mentioned in the previous section, we want to look for possibilities for achieving symbiosis between the systems that we will be using, thereby the overall system. We also want to evaluate each technology in terms of high tech or low-tech solutions with a bias towards low-tech solutions because they tend to be more simply constructed and easier to maintain. Flexibility will be another consideration. Throughout a buildings lifecycle, it may be asked to serve a variety of functions. New technologies may arise as well. So, it is preferable to provide options and opportunities for people to take advantage of new technologies and adapting to new uses without locking us in to any particular function. With this in mind, I will be seeking to put together a suite of technologies that is best suited to this climate and building typology, while being upgradable wherever possible.
36 Technologies under Consideration: Photovoltaics Concentrated Solar Thermal Algae Derived Biodiesel Small-Scale Aquaculture Solid-State Lighting Ground source heat pump Hydrogen Electrolysis Photovoltaics There are now two classes of photovoltaics: traditional silicon-based solar cells and a new class called dye sensitized cells. Silicon-based solar panels have been around for some time and are more or less a known entity to most architects. A typical solar cell converts sunlight into electricity at about 14%, which is not very high. They are prone to impact damage and installed, they require very little maintenance (aside from costs. Solar panel installations can be relatively compact and in some cases are even integrated into mimic photosynthesis. A description of the technology from Dyesol: In basic realisation a dye solar cell comprises a layer of nano-particulate titania (Titanium substrate and photosensitised by a monolayer of dye. An electrolyte, based on an Iodide-Tri-iodide redox system is placed between the layer of photosensitised
37 titania and a second electrically conducting catalytic The dyes and electrolytes can be deposited on nearly any substrate in a printing process that dramatically increases the speed of manufacturing as well as dropping the price to produce them. Unlike traditional and can be printed on cloth, plastic, glass etc. The whole new set of possibilities for the designer, with the potential to have the entire building envelope capable of producing carbon free power. However, while this technology shows enormous potential for the future, I decided against using it in this particular project because I was unable to obtain data regarding the Figure 45 Dye-Sensitized Cell Figure 44 Solar Cell, Circuit Diagram
38 potential power output of the DSC. Concentrated Solar Concentrated solar power uses mirrors or lenses to focus sunlight from a large area to a relatively small target area. Typically some type of solar tracking device is employed to keep sunlight focused on the target area. There are two types of concentrated solar power: way of supercharging the electrical output of traditional photovoltaic cells by concentrating more sunlight on the cells. Typical concentrations are between 2 and 100 Figure 47 Trough Solar Concentrator Figure 46 Linear Fresnel Concentrator
39 concentrates sunlight to create high temperatures. This thermal energy can be used for a variety of functions such as creating steam for power generation, process this technology has relatively low construction costs, they are moderately complex machines that require maintenance and are prone to mechanical failure from time to time. Another downside to solar concentrating and will be affected by high winds. This technology would work well in a parking lot or on top of a large inappropriate for this project because of the previously mentioned issues of susceptibility to high winds and maintenance and operational costs. Figure 48 Parabolic Solar Concentrator
40 Algae Derived Biodiesel Algae grown in bioreactors can grow at exponential rates while consuming carbon dioxide and organic material suspended in the water. The algae that is produced can be pressed produce oil which can be paired with aquaculture or be used to remove organic solids in in wastewater treatment system. This type of pairing achieves our desired goal of symbiosis. However, these systems can be somewhat complex to operate and are prone to malfunction or contamination making them an appropriate for a residential application. Figure 49 Algae Photo-bioreactor diagram Figure 50 Biofence Algae Photo-bioreactor
41 Hydrogen Electrolysis Any excess electrical power that is produced can be used produce hydrogen and oxygen bypassing a current through water. hydrogen gas can be used in any application where natural gas could be used such as cooking, production of domestic hot water, or space heating. Hydrogen can also be used in a fuel cell to produce electricity when other sources are not available or it could be used as a fuel for vehicular transportation. Equipment capable of producing large amounts of hydrogen can be expensive to install and maintain but given the versatility of hydrogen as a potential storage a communal asset. Figure 51 Electrolysis Diagram
42 Small-Scale Aquaculture There is a growing movement of people who small spaces with rather low-tech equipment. In some cases, the material used to create such a system consists of little more than a few plastic 55 gallon drums, a little bit of plumbing, and some air or water pumps. When paired with hydroponic agriculture, a symbiotic relationship can be achieved that enhances realize a respectable return on investment. According to Jonathan Woods: For each dollar that you spend in food, maintenance and utilities, you can expect to Figure 53 Diagram, Hydroponic Planting Bed
43 Figure 57 Photo, Aquaculture Cell 2 Figure 54 Photo, Aquaculture Cell 1 Figure 55 Photo, Aquaculture in greenhouse
44 growing vegetables in the aquaponic system, then you will harvest $1.25 worth of vegetables as well. The total return per dollar is close to three dollars for the aquaponic system and two dollars for the simple suited to such an endeavor with its warm temperatures and extended growing season. Solid-State Lighting Solid-state lighting, also known as LED lighting, offers several advantages over traditional incandescent can use as little as 10% of the energy required to power a comparable incandescent bulb while producing the Figure 58 Electrical Diagram, Light Emitting Diode Figure 59 LED Replacement Bulb
45 same amount of light. LEDs also offer a superior usable lifespan, lasting between 35,000 and 50,000 hours. By between 10,000 and 15,000 hours and incandecents are known to have a useful life between 1,000 and 2,000 no toxic materials. LEDs also produce very little heat, which reduces cooling loads and associated energy costs. The major disadvantages of LEDs are: Voltage sensitivity, Light quality, temperature sensitivity, and a relatively high upfront cost. Light quality continues to improve as the technology matures and proper engineering can mitigate the issues of voltage and temperature. Lastly, the high upfront cost is more than offset by the lifespan of LEDs. Ground Source Heat Pump This uses the same refrigeration cycle as traditional heat pumps but instead of exchanging heat with the ambient air, ground source heat pumps utilize the constant temperature underground to increase temperature and offers a more favorable temperature differential. This translates into less energy required to transfer heat into or out of the building. There are two types of ground source heat pumps: Closed Loop And Open Loop. Closed loop ground source heat pumps use two wells, one well draws water up to be circulated over the coils and the other well serves as a discharge.

51 After reviewing the various technologies available and selecting those that best suit my purposes, I set out to determine the basic massing. I wanted to respect the local building codes wherever possible and respond to the conditions that were present within the neighborhood context. Figure 42 shows just the most basic massing at scale along with the required parking. on the site within the established setbacks. Figure 43 shows a variation with parking underneath the structure and proposed rooftop tensile structures designed to provide some shade for users of the proposed rooftop garden. Figure 44 shows a distributed plan with each unit oriented in the ideal position with the long sides facing north and south. This scheme is problematic Figure 62 Massing study 2 Figure 61 Massing study 1
52 Figure 63 Massing study 3 Figure 64 Massing study 4 because the unit in the center of the eastern column would have access problems. Figure 45 shows a less than ideal orientation for the units, but it solves the access issues of the previous layout. This scheme also offers the advantage of a large central area that could be used as a communal cultivation area and central pond for the collection of rainwater. The close proximity of the neighboring units provides some shade for the eastern and western exposures. Well-designed overhangs and/or a bris de soliel could mitigate the Eastern or Western exposures as well.

56 After establishing the orientation and distribution of the units, I created a couple of systems models in order to have a visual representation of the various shows a basic kit of parts and it contains 3-D graphic representations of the technologies that I intend to incorporate into this project. Figure 49 shows a diagram of all the systems in the project that use water and how they are interconnected. It is important to note that there are separations within the system. Potable water has never used for things that do not require irrigation of non-agricultural planting beds. Also, there is a separation between agricultural and non-agricultural uses such that water carrying human waste is never used for edible crops. This eliminates the possibility of introducing pathogens into the agricultural systems. Figure 50 shows the energy gathering and storage systems. The solar panels in that diagram are arranged was determined to be impractical for Florida given the high winds that might be potentially seen in the case of a hurricane. A wind turbine is included in the mix despite the fact that Florida is not known for a particularly productive wind energy resources because it is relatively inexpensive and is a good complement to solar power. Also included in the mix, there is hydrogen electrolysis equipment and a fuel cell to provide some energy storage capabilities as well as potential to provide hydrogen fuel for vehicles. The fuel cell also
57 provides potential for co-generation. Since fuel cells tended generate large amounts of heat, that heat could be used to provide hot water or space heating during the winter. My intention is to design the overall system such that one could build everything at once, or implement the main features of the system and add some of the secondary functions at a later date as capital becomes available. Having established the massing and orientation as well as the systems, I did a series of sketch models take advantage of cross breezes and light construction to minimize the effects of thermal saturation within the construction materials. I eventually settled on sketch Figure 68 Sketch 1 Figure 69 Sketch 2

Figure 79 shows a deck spanning the pond to allow passage from one side of the property to the other as well as providing access for the aquacultueral operations, such as feeding or harvesting. Landscaping around the pond will include plants chosen to aid in the water treatment process and maintain the health of the pond.

This avoids the possibility of pathogens from human waste 64, aquaculture can be performed in a series of small containers approximately 8 feet across and 4 feet deep. Around the perimeter of the wall, there are hybrid places severe limitations on the amount of production that can be achieved in both the agricultural and the necessary that allows for the achieved separations while

76 Peak power output for the micro-utility portion is 180,00 Watts or 180 KW. With peak hours of sunlight varying between 4 to 7 per day, the system has a theoretical peak output range of 630 KWh and 1260 KWh. Of course, output varies as conditions change. Power usage for the buildings operations are estimated to be: 10KW Aquaponics operations 5KW Exterior lighting 83KW Excess output available for export back to the grid at peak production and usage. Hydrogen output is rated at 20 kg 99.99% purity of 12 16 vehicles. Additional capacity can be added by adding additional units. Excess production can be stored in tanks underground. Stored hydrogen can be used in a fuel cell during times of no solar output. in the greenhouse in the long central aquaculture trough by dividing it into segments. Approximately 3000 ft. of hydroponic growing beds are available for cultivation of fruits and vegetables with an upper-level crop cultivated overhead such as orchids for additional production possibilities.

ABSTRACT: The world is facing two fundamental problems. The first problem is a rapidly increasing demand for energy. The second problem is increasing greenhouse gas emissions that are directly resulting from our energy consumption. The primary greenhouse gas in question here is carbon dioxide produced from the burning of fossil fuels. It has been demonstrated through scientific articles and studies that carbon dioxide is directly linked to rising atmospheric temperatures. Buildings represent a significant percentage of this CO2 production. Many architectural theses and treatises have been written advocating architecture that is more energy efficient and which uses sustainable materials and processes as necessary steps towards solving the global warming crisis. With the threat of global warming looming, everyday architecture must go through a transformation. Sustainable buildings should not be limited to rarefied architectural gems. Instead, sustainable architecture should become a commonplace condition in the built environment. In order to achieve this, we need sustainable architecture that not only addresses the environmental issues but also pays for itself and pays the building owner for taking on such a task. To answer this need, I intend to design a mixed-use multifamily building that exists in the environment as a living system. As all living things, it must function utilizing the resources available in that environment. It must have a practical and economically viable on-site energy production and storage methodology that is environmentally benign and takes advantage of freely available natural resources. It must react to changes in the environment to better manage its resources and it must be able to store resources for later use. Lastly, it should foster sustainable living practices of its occupants. By building in this way, architecture can take on a new role as symbiant rather than parasite in the environment, producing its own pollution free energy and clean water. Each building acts as a life support system for its inhabitants but is also part of a macro scale biosphere. If resources are managed carefully, an exportable energy surplus can be generated representing an economic benefit to the owner. This provides an economic directive to adopt sustainable practices.
