1.0 INTRODUCTION
Introduction At the forefront of survival, human beings and animals alike confront weather on a daily basis. Shelter is our primal response to protecting ourselves against weather conditions and as such, weather constantly dictates and informs our design of buildings. Its challenges are often faced and overcome through the prediction and understanding of patterns as well as our interactions with phenomenons of weather. This weather research station will focus on a specific aspect of weather to not only enrich the city with pragmatic knowledge but also poetic insight into precipitation.

2.0 WEATHER PHENOMENON UNDER STUDY
Precipitation In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. Precipitation occurs in many forms, some of them include drizzle, rain, sleet, snow, graupel and hail. This project chooses to explore the potential of a scientific research facility that focuses on the most prevelant weather phenomenon in Portland. Portland receives approximately 40 inches of atmospheric precipitation annually or 8 months of rainy weather. The study and research of rain provides a sense of locality, building strong connection to the region while engaging the community with precipitation as its medium. The relevence of the research conducted at the institute will not only serve the architectural community but to the city and Pacific Northwest at large.

The traditional Malay house is a timber house built on stilts featuring high ceilings, large windows, an open interior space with minimal partition walls as well as a large overhanging gable roof. The rumah panggung is elevate on stilts to capture higher wind velocities while its high ceiling allows hot air to rise and ventilate allowing colder air to fall and cool the interior. Its roofing provides good insulation and shade against solar exposure while its large windows allow for cross-ventilation. Additionally, glare is also further reduced and controlled by the application of louvers and carved wooden panels. The lightweight construction of the Malay house is well suited to the hot and humid climatic conditions of its environment as it utilizes materials featuring low-thermal capacity and high insulation properties. As timber is plentiful in Southeast Asia, rumah panggungs are mainly built with wood utilizing tongue-in-groove joints as its main construction technique. Besides being well adapted to the environment, the house has also evolved a prefabricated building system which can be flexibly retrofitted and extended according to the growing needs of the family.
Response to Culture The rumah panggung is one of the richest components of Malaysia’s cultural heritage. This housing typology is appropriate to local climatic conditions and expresses the way of life of its inhabitants. It is often decorated and highly ornate with carvings that reflect cultural aesthetics and traditions. Fig. 3

Design Strategy Windcatchers are traditionally constructed out of thick ceramic with high insulation values built closely together with high walls to maximize shade at ground level. Windcatchers are usually built with refrigerating features such as water reservoirs and hanging wet towels to effectively takes advantage of evaporative cooling effect of the dry climate. They also feature small windows to minimize glare and direct heat gain from sunlight. Windcatcher designs vary according to specific local climatic conditions mainly dependant on the direction of airflow. Typically they feature from one to eight openings at various heights to direct air into buildings. Windcatchers function by either directing airflow downwards through direct wind entry, ventilating airflow through temperature differences of the environment and interior spaces, or utilize solar heat to exhaust hot air from buildings. In combination with courtyards and domes, the windcatcher is open towards prevailing winds to cool the building interior relying on the velocity of winds for its cooling effect. Windcatchers facing away from prevailing winds take advantage of pressure differentials of to draw air from the interior. The hot air of the environment drawn through an underground canal linked with the windcatcher is cooled by being in contact with cool water vapor and temperature of the earth decreasing the structure’s overall temperature. In windless environments, the windcather acts as a solar chimney allowing hot air to travel upwards and escape through its opening while trapping cool air below.

The Minka or Kominka is a traditional Japanese single family home built on wooden columns elevated on top of a flat rammed earth or stone foundation. In order to avoid moisture from seeping into the floor of the building, the building is elevated several inches and is laid across horizontal wooden floor beams. This crawl space usually exists underneath the living room, providing natural ventilation from below and cooling in the summer. One defining characteristic of traditional Japanese houses is the large curved roof and deep eaves to protect the house from the hot summer sun. Traditionally, Japanese roofs were covered with shingles of woven straw but to reduce potential fire hazards, they are also clad with ceramic tiles. Japanese roofs are sloped instead of flat, allowing rainwater to flow off easily. Partition walls and doors are made of translucent rice paper held together by a lattice of bamboo that slide open to conserve space. These doors or room dividers are translucent to reduce glare from the sun while allowing light to diffuse into interior spaces.
Response to Culture The distinctive feature of a traditional Japanese building is the way in which the house is open to nature. The main materials used are wood, earth, and paper, and the construction spreads out sideways rather than upwards. Another unique feature of Japanese housing is that houses are set to have a limited lifespan and are generally torn down and rebuilt after a few decades.

A tipi is a conical tent approximately 12 to 25 feet tall and is traditionally made of wooden poles covered by stuffed fabrics or animal skins pegged to the ground. Tipis are built to be durable; Providing warmth and comfort in the winter while staying cool in the heat of summer and dry during heavy rains. As the conservation of heat is essential to living in harsh unprotected climates, a small fire is set in the center of the floor for heat and cooking. The smoke is then exhausted through an adjustable smoke flap of the opening at the top of the tipi. A liner covering the exterior serves as an additional layer of insulation and is usually stuffed with grass in very cold weather conditions. In warmer weather however, the liner is rolled up to allow cooler wind to enter and ventilate the interior space.

Tipi construction vary according to locally available materials. Lodgepole pine is typically used in the Northern and Central plains while red cedar is used in the Southern Plains. Tipis can be deployed and disassembled quickly making them versatile. The adaptability of these nomadic dwellings allow the American Indians to live in various climatic conditions. Tipis are typically left unpainted while painted tipis feature geometric patterns and designs portraying celestial bodies, animals or sacred symbols.

Design Strategy Log cabins are usually constructed with round hand-worked logs, and were the first homes of pioneer colonists of North America. Log cabins are built from logs laid horizontally and interlocked on the ends with carved out notches. Log cabin construction typically utilizes straight and tall coniferous trees such as pine and spruce. Wood as a building material features a relatively high thermal mass and latency serving as a good insulator. It’s ability store heat during the day and gradually releasing it at night along with its abundant availability makes it a superior building material for cold climates. It’s simple construction also contributes to its popularity. A log cabin can be erected from scratch in a few days by a family in any weather or season without the use of mortar or other hardening agents.

The roundhouse is a primitive building type that is a low, circularly planned house featuring a large roof with low walls. Most roundhouses were built from local materials found on site. The wooden walls are typically framed by wood posts and covered with daub made from clay, soil, and straw. The daub is made from equal proportions of cow manure, earth, clay, and straw with water added and mixed into a heavy paste. This coating ensures that the house is air-tight and weatherproofed. The upright structural poles are usually around 4-6 inches thick with their ends charred in a fire and buried about 8-12 inches deep. Charing the wood that will be buried below the ground protects the wood from rotting and structure from collapsing. The roof is constructed from large timbers and densely thatched with straw to trap heat. The main feature of the interior space is the central open-hearth fire that is maintained 24 hours a day to cook food, provide warmth and light. The smoke from the fire that accumulates in the roof space heats the building while allowed to slowly leak out through the tightly knitted thatch.
Fig. 5.2
Response to Culture As the roundhouse does not feature any windows, it relies on the doorway for natural light. The position of the doorway may also have had a religious significance. The wattle and daub composite material is highly used in modern eco-building construction due to its low environmental impact and highly sustainable materials.

The Institut du Monde Arabe features mechanically controlled facades that control the level of natural lighting drawing inspiration from the traditional lattice work that has been used for centuries in the Middle East to protect the occupants from the sun and provide privacy. The system incorporates several hundred light sensitive diaphragms that regulate the amount of light that is allowed to enter the building. The ocular apertures are not only beautiful aesthetically but also functions as an environmental control feature as well through the closing or reducing the aperture sizes. During the various phases of the lens, a shifting geometric pattern is formed and showcased as both light and void. Squares, circles, and octagonal shapes are produced in a fluid motion as light is modulated and filtered through it. Lighting in interior spaces experience dramatic changes along with the building’s exterior appearance. As the institute serves to strengthen and educate the public about the Arab culture in France, the mashrabiyya, an archetypal Arabic screen architecture is incorporated in its design. The synthesis of traditional Arabic architectural elements into a modern design allows the building to serve as a beacon for the interaction with Arab culture.

Mountain Dwellings is a 80 unit apartment complex above a multi-storey car park by Danish architects Bjarke Ingels Group (BIG). As Copenhagen’s topography is flat, the building is tiered and stacked as a sloping hill. Instead of having a separate parking structure or lot for the cars of the tenants, parking is seamlessly integrates into the building. The two programs sharing one material-intensive foundation gives the dense housing project a feeling of safety to the parking garage at all hours. As the parking area is mostly concealed, it preserves the neighborhood’s pedestrian-friendly character. Atop the hillside units, each home enjoys a penthouse view, a private garden and plenty of fresh air and sunlight. The mountain dwellings combine features found in suburban living with urban density by providing roof garden terrace spaces. These roof garden terraces have built in seasonal planters providing shade to units in the summer while allowing natural lighting in the winter. The outdoor planters are carefully positioned to maintain privacy between units and also double as rainwater collectors, storing water for irrigation during the dry season. The north and west facades of the building are covered by perforated aluminum plates in the image of Mount Everest to allow natural light as well as ventilation in the parking spaces.

The VanDusen Botanical Garden Visitor Centre by Perkins+Will is Canada’s first certified Living Building designed to be LEED Platinum certified featuring various green technologies and annual net-zero energy consumption. The building was strategically situated to avoid destroying the rare trees, shrubs and plants around the site to preserve its natural environment. The Visitor Centre functions off the grid through the use of locally available renewable materials, geothermal boreholes, solar photovoltaics, and solar hot water tubes to achieve its annual net-zero energy status. The building is primarily constructed out of wood with the roof constructed out of glulam post-and-beams supporting a green roof. Rainwater is collected on its roof, filtered and used as greywater throughout the building. The blackwater on the other hand, is treated by an on-site bioreactor and released into a percolation field and garden. The building features a large skylight protruding from the roof landscape, producing an atrium space in the interior with a warm orange glow, reflected by the natural wood. While providing natural lighting in the building, the oculus assists with natural ventilation by operating as a solar chimney. It also serves as an aluminum heat sink, which converts heat from the sun creating air movement in its interior spaces through convection. The roof garden also replaces the vegetation displaced by the building itself and helps reintegrate vegetation into the architecture. Building materials are carefully chosen according to their carbon footprint, ability to be recycled and as well as their life cycles in order to be considered appropriate and long-lasting components.

The current condition of the site found is leveled with remnants of the previous building’s footprint in the form of tiles and concrete foundation found on site. The fenced- in abandoned site features a parking lot directly across from it and is located in a quiet and isolated residential neighborhood.
The site is a disused deciduous woodland park planted for butterflies and insects. It was named ‘butterfly’ for its importance as a habitat for butterflies. The site is currently fenced due to construction and is also heavily covered with trees, featuring a large transmission tower. The site is located close to a car dealership as well as a boat home community.

SE Oaks Park Way
Site Section
Currently a boat dock, the Sellwood bridgehead site features a tiered topography slowly meandering and sloping down towards the river. Although the site is considerably noisy due to traffic from Macadam Ave and the Sellwood bridge, it benefits from its proximity and accessibility. Being right by the Willamette river with no steep slopes or dense forest makes the site superior in view and accessibility.
Located between Sellwood Riverfront Park and Oaks Amusement Park, the site is a dense forest that features a nature trail encircling it. The river can be access along 3 dock points in the park but cannot be seen through the thick canopy of trees from SE Oaks Park Way that wraps around the entire site. The middle of the site as well as the South Eastern edge features a transmission tower and small shallow pond respectively.

9.3 CONCEPTUAL DESIGN PROPOSAL Formal Ordering Systems
Formal Ordering Systems The building’s centrally planned layout draws inspiration from the precipitation cubes found in the box of weather. The building is divided in 2 parts with circulation spaces around the core as well as between the separate spaces. This order allows the building to be modular and efficient in its programmatic layout while allowing site forces to flow and guide the form of the building.
