DIRECTIONS: Write, speak or perform your answers as directed below.
6. Plan a Housing Solution. Make drawings on sheets of graph paper (or use paper, index cards, straws, tape, string, paper clips &/or play-dough to make a 3-D model) of an architectural structure that addresses all the needs of a perfect and affordable home for a low income family. It can be situated in any specific site in the world, but must address all natural, cultural, human and visual site conditions, plus safety and sustainability. Take 15-20 minutes to create it. When done, describe your drawing or model to your teacher, and/or write a paragraph to explain all the features of your house and how it meets the criteria above. 7. Debate a water issue. With a partner, consider several issues that may arise regarding an Army decision to build a canal in your town at the site of a stream that flooded recently, causing one death and a million dollars in damages to the neighborhood. Consider each issue, then pick just one and prepare to debate each other, either ‘pro’ or ‘con’. You may write brief notes on another page if you wish to use in the debate:
a) The Environmental Protection Agency is concerned that endangered species of a native plant, bird and snail inhabiting the proposed canal site and reef at mouth of the stream may become extinct due to loss of habitat and erosion from construction b) Some of the water has always flowed to kalo (taro) farms just below the proposed canal site and subsistence farmers could lose their livelihood c) A national hotel chain and small local businesses will be able to provide more jobs if the
canal is built and water diverted to support their interests d) If the canal is built at the proposed site and a portion of the water is diverted, a proposed
low income housing development will benefit needy people. When ready, take 2 minutes each and debate both sides of the issue you chose to address before your teacher and two other students. Take an additional 1 minute to rebut each others’ arguments. Discuss with your audience who would persuade the public and policy makers with their response more & why.

Water Power in Hawai’i: Wai
The earliest settlements now known in Hawai’i are on the northeast side of the island of O’ahu. The oldest site excavated — its earliest parts dated between 300 and 600 A.D. — lies along this windward coast on land now occupied by Bellows Air Force Base. The first Hawaiians preferred locations like this which furnished ample water for their crops and other uses. Recently uncovered walls of lo‘i (pondfields) indicate that wetland kalo was grown on lands mauka (toward the mountains) of Kawainui.

At a site in Hanalei Valley, Kaua‘i, that has been dated to approximately 6IO A.D., archaeologists have uncovered the first known instance of lo‘i fed by an ‘auwai (irrigation ditch). This irrigation method became extremely important in later years as the population grew and spread throughout the islands. ‘Auwai ranged from simple to elaborate in construction, but all shared a basic design: at the head of the ditch, water was diverted

into the ‘auwai from springs, streams, or pools and was led downhill to the lo‘i very gradually, with the result that the water moved slowly and its passage did a minimum of erosive damage. The ‘auwai were lined with carefully fitted rock, at least near their heads, and were routinely maintained in order to prevent soil and debris from filling the ditch and impeding the flow of water.
The engineering of the ‘auwai was excellent. With only the
simplest tools, Hawaiians modified natural stream flows and devised new routes that systematically exploited the slope of the terrain to carry water into their fields with great efficiency. These aqueducts, some of them very elaborate, are considered the finest in the Pacific islands. So well designed were they that later, when Western engineers planned irrigation flumes for commercial sugarcane production, they often followed these channels laid out by the Hawaiians of old.
Though ‘auwai were principally for irrigation, they also served
to furnish water to some house sites. Since water belonged to the gods and was therefore valued beyond human terms, no one could claim its ownership or rights to its sole use. There are few records of quarrels over water use until foreigners came, bringing with them different concepts of water rights.
Engineering Waiāhole Ditch & Tunnel System
The first sugar cane irrigation ditch (the Rice Ditch) was built on Kaua‘i in the mid-1850s. In 1905, the first engineer was commissioned to investigate the feasibility of developing water in the Ko‘olau Range on O‘ahu, but it took until 1913 to venture such monumental construction by the newly formed Waiāhole Water Company. When completed a little more than 3 years later, the system included a large number of tunnels ranging in length from 280 feet to the 2.76-mile long main trans-Ko‘olau tunnel.

Excavation in those days was far from predictable. Access road and trail construction in the rugged terrain was especially difficult and the workers had to contend with voluminous flows of water as the first dike was pierced. Initially, supplies had to be moved by mule but eventually a 10-mile railroad and ocean pier made the task more efficient.

July 30, 2007 - Waterflow along the Waiāhole Irrigation System is controlled partially by a series of gates. Earlier this month, Gate No. 31, located in a tunnel drilled on the Windward side of the Ko‘olau range, was not responding to phone commands, so water systems manager Vernon Pico had to trek up to the site and manually open the gate to let more water go through. Pico’s vast worksite is shown in the graphic below.
Agribusiness Development Corporation’s water systems manager, Vernon Pico supervises a crew of five who maintain the Waiahole Irrigation System. After graduating from Campbell High School in Ewa, Pico furthered his education at Leeward Community College in a carpenter apprentice program. He started work as a carpenter making repairs to the system, then was promoted to his current position.

Waiāhole Water Rights Issues

Photos by Bruce Asato, The Honolulu Advertiser & www.earthjustice.org/about_us/offices_staff
Nearly a century ago, water vital to taro farmers, streams, and the estuary
on O‘ahu’s east side was diverted to sugar plantations. The plantations are gone now, and Earthjustice represents farmers and Native Hawaiians in an effort to restore the water to where it belongs.
The Waiāhole case arose from the efforts of small family farmers and Native Hawaiians, led by citizen groups (Hakipu‘u ‘Ohana, Ka Lahui Hawai‘i, Kahalu‘u Neighborhood Board, Makawai Stream Restoration Alliance) and a coalition of supporters to restore streams originally diverted by Central O‘ahu sugar plantations. O‘ahu Sugar’s 1993 announcement of its closure in 1995 sparked a monumental legal battle over the diverted water -- in the words of the Hawai‘i Supreme Court, a case of "unprecedented size, duration, and complexity."
The windward parties sought to: return diverted flows to the streams to restore native stream life, such as ‘o‘opu, ‘ōpae and hīhīwai; protect traditional and customary Native Hawaiian practices; support the productivity of the Kane’ohe Bay estuary; and preserve traditional small family farming, including taro cultivation. But large scale agricultural and development interests, including Campbell Estate, Robinson Estate, Kamehameha Schools, Dole/Castle and Cooke, and others, joined by the State, pushed to continue the flow of Windward water to leeward lands to subsidize golf course irrigation, short-term corporate agriculture, and housing development.
This debate is likely to arise again as demands for Waiāhole water increases on both sides of the island.

-Radiocarbon Testing Challenges Our Understanding of Ancient Hawaiian
Architecture
An aerial view of a large war temple (Loaloa) on Maui.
Courtesy Michael Kolb and Northern Ill inois University The development of monumental architecture and social complexity on the Hawaiian island of Maui occurred over a span of at least 500 years, according to the most detailed study to date on the antiquity of the island's extensive temple system. The findings, in the August 2007 issue of Current Anthropology, challenge previous conceptions of ancient Hawaiian civilization by identifying cycles of temple construction that coincide with politically charged periods of warfare and island consolidation. "Because the islands are relatively isolated from the rest of the world, the development of monumental architecture and complex society in Hawai‘i is of keen interest to archaeologists," writes Michael Kolb (Northern Illinois University), who spent more than a decade locating and excavating temple sites. "In many ways, Maui represents an excellent test case for state development. Its monumental architecture is directly linked to economic, political, and ritual development, not unlike the most famous early civilizations, such as the Maya or ancient Eqyptians."

Kolb conducted radiocarbon-dating* analyses on samples from forty ruins on the island of Maui, including several newly discovered temples. The radiocarbon dates indicate the earliest temples were built in the 13th century, with construction continuing into the early 19th century. Prior research had indicated that Maui's temples, known as heiau, were built within a span of decades near the turn of the 17th century. Kolb's study also identifies an important shift in temple construction from open-air temples used for ancestral worship to enclosed, more elaborate temples used for sacrificial offerings to war gods. Large temples often covered more area than a football field and stood 40 feet in height. "The Hawaiian civilization did not use ceramics, which is typically why radiocarbon dating is relied upon by scientists," says Kolb. "Before a temple was built, the land would be set ablaze to clear it from vegetation, leaving behind charcoal remains. We also were able to gather samples for dating from the sites of ancient ovens and bonfires." The ancient people of Maui stacked lava rocks to form the foundation of the platform temples, often built on the faces of cliffs or other high points on the island. The more elaborate, terraced temples were adorned with altars, oracle towers, offering pits, and god or ancestral images carved from wood or stone. "Oftentimes, in a show of economic might, a conquering chief would remodel, build additions to, and re-dedicate a rival's temples," explains Kolb. "Many of the early structures were modified or new ones were built with enclosures on top. Access was limited to reward loyal constituents, and sacrificial worship became more of a focus."
Carbon Coal
Graphite Diamond
What is radiocarbon dating? Carbon is what’s in your pencil (graphite) in your barbecue (coal) and in your jewelry (diamond). Carbon is abundant on Earth in various forms and scientists can figure out how old carbonaceous materials are by a radiometric dating method that uses the naturally occurring isotope carbon-14 (14C) to determine age up to about 60,000 years!

BONUS READING: More About Radiocarbon Dating The technique of radiocarbon dating was discovered by Willard Libby and his colleagues in 1949 during his tenure as a professor at the University of Chicago. Libby estimated that the steady state radioactivity concentration of exchangeable carbon-14 would be about 14 disintegrations per minute (dpm) per gram. In 1960, he was awarded the Nobel Prize in chemistry for this work. One of the frequent uses of the technique is to date organic remains from archaeological sites. Plants fix atmospheric carbon during photosynthesis, so the level of C14 in living plants and animals equals the level of C14 in the atmosphere. Radiometric dating (often called radioactive dating) is a technique used to date materials, based on a comparison between the observed abundance of particular naturally occurring radioactive isotopes and their known decay rates.[1] It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself. Among the best-known techniques are potassium-argon dating and uranium-lead dating. By allowing the establishment of geological timescales, it provides a significant source of information about the dates of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological remains and ancient artifacts, the best known technique in this field being radiocarbon dating. Raw, uncalibrated, radiocarbon ages are usually reported in radiocarbon years "Before Present" (BP), "Present" being defined as AD 1950. Such raw ages can be calibrated to give calendar dates.

BONUS READING: More About Carbon & Allotropy
Allotropy is a behavior exhibited by certain chemical elements: these elements can exist in two or more different forms, known as allotropes of that element. In each different allotrope, the element's atoms are bonded together in a different manner. For example, the element carbon has two common allotropes: diamond, where the carbon atoms are bonded together in a tetrahedral lattice arrangement, and graphite, where the carbon atoms are bonded together in sheets of a hexagonal lattice. Note that allotropy refers only to different forms of an element within the same state of matter (i.e. different solid, liquid or gas) - the changes of state between solid, liquid and gas are not considered allotropy. For some elements, allotropes have different molecular formulae which persist in different phases - for example, the two allotropes of oxygen (dioxygen, O2 and ozone, O3), can both exist in the solid, liquid and gaseous states. Conversely, some elements do not maintain distinct allotropes in different phases: e.g. phosphorus has numerous solid allotropes, which all revert to the same P4 form when melted to the liquid state.
The structure of eight allotropes of carbon are shown in this diagram:
a) Diamond
b) graphite
c) lonsdaleite
d) C60
e) C540
f) C70
g) amorphous carbon
h) a carbon nanotube

IAO, Maui » Maui High School students tie palm fronds to the A-frame of a traditional Hawaiian house at the state's Kepaniwai Park in Iao Valley in a hands-on class that teaches them about native culture.
"Not too wide. I'd rather have the palms too close than too far," said master builder Francis "Palani" Sinenci, who has helped to build more than 60 native Hawaiian structures.
The construction project, sponsored by the county and state, involves the building of a Hawaiian "hale halawai," or gathering house, to replace a "hale noho," or sleeping house, burned down a couple of years ago.
Sinenci, who is volunteering his labor and expertise, point out that the hale is being constructed according to rules adopted on May 7 by the county Department of Public Works and Environmental Management establishing standards for indigenous Hawaiian architecture.
The rules, mandated by the Maui County Council, include limits on the size of the hale, materials to be used in making them and when a fire sprinkler system is required in the structure.

Similar rules are being developed by the City and County of Honolulu's Department of Planning and Permitting, following the adoption in July of an indigenous architectural ordinance on Oahu.
Rather than using traditional sennit, students are knotting the fronds onto the structure with nylon parachute cords because of their proven strength and resilience, he said.
Because of the lack of affordable native hardwood, some non-native trees such as ironwood and inkberry are used in the structure, but the wall posts are made of native ohia, he said.
During a day-long workshop Monday, the 19 students from a Hawaiian studies class at Maui High helped in gathering the palms from a storage shed and taking turns tying the palms on the 30-by-40-foot hale.
"It's good because you learn more of the Hawaiian culture," said Paulo Samita Jr., a freshman.
Hawaiian studies teacher Kailani Ross said the students learned about indigenous plants, the names of various posts in a traditional hale and the cultural protocols in preparing to erect a native structure.
Ross said eventually the Hawaiian studies class would like to build a hale on the school grounds and is looking for funding sources.
Several years ago, erecting a traditional Hawaiian hale would have been difficult because the county building code on Maui was based on using Western techniques and materials.
But county ordinance and rules now allow the use of native woods and other materials within limits and have established a way for the traditional hale to be built by a new generation of master builders.
Sinenci, who has taught a course on traditional Hawaiian hale construction at Maui Community College, has trained 10 master builders, including one from Oahu and another from Kauai.
At the Iao hale site, apprentice Prescott "Kepa" Guillermo hopes to become the 11th.
Guillermo, who has worked as a certified arborist and tree trimmer, said he has enjoyed the experience since he started the apprenticeship in July. "I'm learning my roots," he said. "It's a great privilege."

Maui Community College’s Eco-village
LIVING THE SUSTAINABLE LIFE By Don Ainsworth
A group of Maui college students is awakening to the challenges and benefits of sustainability. Maui Community College Instruction in Sustainable Technologies (MIST), a program funded by the Department of Energy, a grant from the Sohn Foundation and community donations, is not only educating students about sustainable technology, but also hopes to impact resource use island-wide.
Since 1994, student interns have been learning both theory and practical applications of alternative energy and conservation-related systems. This semester, 16 students enrolled in two new courses are designing and constructing an "eco-cottage" as a demonstration project for the community. Because of the desire to utilize these technical skills throughout Maui County, students from Hana, Lana‘i, and Moloka‘i are participating.
The eco-cottage, located on the Maui Community College campus, will be a prototype used to demonstrate the potential of resource conservation and the ability to live in areas without access to electricity, public water and sewers. As the work progresses, the structure will be visible from Kahului’s main thoroughfare, Kaahumanu Avenue.

From Cottage to Village
After completion of the eco-cottage, an eco-village will be constructed which will consist of five 3-bedroom dormitory units around a pentagonal main building used as a common area. The central building will house classrooms and labs for students studying for an Associate of Science degree in Sustainable Technologies, as well as provide recreation and meeting facilities.
The buildings, sited in a cluster configuration, will make efficient use of trade winds and solar paths. Both the eco-cottage and eco-village will provide students an opportunity for hands-on experience in the design, installation and maintenance of sustainable systems, as well as create a research facility for real-time testing and development of energy-related products and systems.
The eco-village will incorporate the following technologies: 1) Solar stills and filters to treat water from an existing brackish well on campus in order to provide drinking and utility water; 2) Composting toilets, gray water systems and mechanical conservation devices. A bio-filter meander will process the gray water and provide biomass for composting and, eventually, bioconversion; 3) Passive cooling and ventilation utilizing architectural systems as well as landscaping and siting; 4). Solar power to heat water and provide basic electric power, utilizing building materials with built-in solar thermal and photovoltaic system components; 5) An energy management system that will accept input from solar, wind, on-site generation and electric grid sources and maintain power storage bank integrity; 6) Propane-powered refrigerator, generator, range and back-up water heater; 7) Biomass anaerobic digestion conversion system to convert green waste, wet kitchen waste and biomass crop into soil extenders, fertilizers and methane gas. The methane gas will be used to eventually eliminate the need for propane.

BONUS READING: Re-Use Principles In Action
The dorm units will be designed and constructed in such a way that they can be sold and moved from the site. New buildings, incorporating the latest technologies, will then replace the initial units. Sales from the older units, in addition to dorm rental income, use fees and non-credit seminar income will provide continuing financial sustainability.
The eco-village residents will be the students themselves. As members of a sustainability team, they will be responsible for the caring and feeding of the systems. Living in the units will give the students an understanding of not only the technology but the lifestyle changes required in a sustainable setting, such as altering times for use of electric power and limiting water use.
To support their involvement with sustainable technology, the students will have access to e-mail, the Internet, the University of Hawaii HITS television instructional system, MCC's Skybridge outreach learning system and the CU/CMe video interactive communication system.
Maui Community College offers not only an innovative sustainable technologies program, but also the only one in the state. Ground-breaking and blessing ceremonies for the eco-cottage were conducted in February. Building and site tours will be coordinated through the campus MIST office. For more information, call Jane Yamashiro at 984-3262 or Don Ainsworth at 984-3384. The eco-village will offer "real-world" study of sustainable technologies that can be practically applied in Hawai‘i. It is the program's goal to demonstrate that these technologies are of value now and in the future to conserve our valuable resources.

PREFAB FRIDAY: Solar Green Homes Delivered by Truck! by Mahesh Basantani
Elevation of PowerPod with “Butterfly Roof”
The houses are factory built in the US and currently are delivered in pieces by truck to states in New England and to New York. Their concrete foundations are pre-poured, and space is left for lighting, plumbing, and wiring to be completed on site.
One highlight is the metal roofing, which serves dual purposes. It provides heating during cold seasons and generates electricity. Water runs in plastic tubes installed under the roofs and is heated by the sun, which supplies hot water and heats the homes. Also, roof-integrated solar photovoltaic (PV) panels generate a portion of the homes’ electricity needs.
The multi-units range from affordable housing to high-end urban condominiums. The PowerPods could be used as energy-efficient guest houses, vacation homes, offices, studios, or even house boats, and come with a choice of roof variations. The “solar butterfly” roof design collects rainwater, maximizes the use of daylight, and is fitted with solar PV panels to generate electricity - all for about $100,000!

structure challenges. Each team will build and test its structure and record its results.
4. When the teams are done, have them rotate so that each team is working on a new structure challenge, using the information gained from the team that already worked on that challenge. Have teams again record their data and analysis. Continue rotating until all teams have built and tested three different structures. Once this is done, bring the class back together and discuss the results. You may want to have one student record all the results on the chalkboard. Which features, if any, helped resist which challenges? Which features helped resist all challenges?
Challenge #1 High Impact: A relatively short, wide building will be more stable than a tall, narrow building. Another design feature that will help the building's stability is to concentrate most of its mass near the bottom, since a top-heavy building will tend to be unstable. Since many of the buildings in earthquake-prone cities are skyscrapers, most of them are narrower at the top than the bottom. An extreme example of this is the pyramid-shaped Transamerica building in San Francisco, California.
Challenge #2 Hillside Home: The building will be most stable if it is given a wide foundation, such as a fan of paper to skirt its bottom to provide more surface area against the side of the hill. Another strategy would be to brace the building by attaching straws to the downhill wall that angle down to the hillside surface. Again, as with the High Impact challenge, a relatively wide building will be more stable than a relatively tall, narrow building.
Challenge #3 Rolling Along: This building will be stabilized by focusing most of its mass near the bottom. A pyramid shape would be a very clever idea, and is unlikely to tip over even when it is being shaken quite rapidly. In some communities where the ground beneath buildings is quite soft, such as the Marina district of San Francisco, California, which was badly damaged in 1989, the buildings were literally shaken apart because the soft ground magnified the intensity of the earthquake. Explain that some new buildings have actually been constructed on rubber mountings that absorb the shock waves.

Hale Maquette Project A maquette is a scale model created by architects and engineers to provide a visual of a structure they propose building. Your maquette should be build to a scale of 1: . BEGIN … by choosing the type of hale you wish to create. Your choices are:
√ ancient heiau √ traditional hale √ modern eco-hale NEXT … either choose a real or an imaginary site in your community to put your structure on, and a time in which this structure will be built (ancient Hawai‘i, today, in 2050 or ________??) RESEARCH … using the Internet, the library and interviewing people (yes, you must do all 3, so write down your sources!), find out these things about your type of structure: √ what was the purpose of similar structures in the past? √ what different kinds of structures like this have been built here in Hawai‘i?
√ who would want a structure like this in your community (past, present or future)? √ what purpose(s) will your new structure serve and for whom? √ how does the above information affect the design of your structure? √ in what 3 ways can you incorporate the science you are learning into this project?
DRAW … sketch 10 small diagrams showing the most important design considerations for your proposed structure. These must include natural (esp. topography & hydrology), cultural (esp. history), human (esp. environmental quality) and visual (esp. spatial). DRAFT … create 3 scale drawings of your proposed structure, including: √ 1 Floor Plan √ 1 Cross-section √ 1 Elevation √ (optional) Perspective Drawing GATHER … bring clean, recycled materials from home as much as possible. These can include: flat cardboard, various thicknesses; plastic; cellophane; thread & string; dry pasta, various kinds; natural fibers such as leaves, bark, small stones. Avoid using materials that will wilt, attract insects, break too easily, interact with glue poorly. PRESENT … describe your research & maquette to an audience on: __________________

ARCHITECTURAL DESIGN: RESPONSES TO SITE CONDITIONS
Hale hālāwai (gathering house) at Hana, Maui
Site conditions can be classified into 4 categories:
1. Natural – topography (shape of the land); geologic base (soil, erosion, etc.); hydrology (water, drainage); vegetation (existing & desired plants); wildlife (habitats, protected species); climate (sun, temperatures, precipitation, wind)
2. Cultural – existing land use (neighbors, noise, roads); transportation
(access by vehicle, on foot, disabled, parking, public bus routes); utilities (sewage, electricity, gas, sustainability); boundaries (property line, easements); legal regulations (building codes, bylaws, zoning, development proposal); history (past site use and history, current importance, protocols for use, kapu)
3. Human – current use & needs of site (observations, interviews);
environmental quality (safety from crime, traffic, natural hazards); proposed structure’s impact (quiet, cleanliness, convenience, privacy, community identity, diversity, structure’s scale, continuity of site uses, cultural expression, social interaction needs & opportunities)
4. Visual – site features (outstanding nearby features, natural or human-
made); views (from and of proposed structure, seasonal affects of views); spatial qualities (outdoor/indoor spaces, variety, uniformity); sensory qualities (sounds, smells, touch, colors from proposed structure and around site)
Usually, architects and engineers will create visuals of their proposed structure and how they plan to respond to the site conditions using CAD (computer assisted drafting). However, they often start with simple small sketches, usually drawn to shown an aerial view of the site.
When architects and engineers plan to build
something, they first look at the site in which it is to
be constructed and they consider the purpose of
the structure they will build. This was true in
ancient times in Hawai‘i and it is still true today.

C) Group Brainstorm: Plan Your Project As a group, decide if you want to …
explore ocean OR land-based water energy technology recreate a model of existing technology (you will have to
research this) OR design your own model (you will have to pose research questions, hypotheses and experiments)
1. List all the options you like here (use additional paper if needed):
2. List the pros & cons of these ideas here (ease, feasibility, usefulness):
D) Group Brainstorm: Project Evaluation Tell the class what your group’s best idea is and listen to their ideas, then discuss how you would each like the projects to be evaluated.
How many points for learning as you work? Will science learning and progress/cooperation as a team both count?
How many points for a quality final project? How much time is needed to gather materials, do research or
experiment, and create the model? How will you demonstrate understanding of the physics
involved in your project (written report, presentation notes, PowerPoint?)
Who & how will evaluate your final projects? How could the project be shared and/or extended in a way
useful to the class, others at school, home or in the community?
