5.0 Innovation in Urban Design, Transportation, and Affordability
5.1 Urban Regeneration:
We use the word “regeneration” to indicate our dedication to cause as little disturbance as possible in our mission to revamp the city and its social housing system. Taipei city has very little available space, and we do not wish to destroy pre-existing buildings, so our solution is to build on rooftops.
We studied the rooftop configurations of Taiwan, and came up with dimensions for our house that are adaptable to the most common forms of buildings in the city.

Our design also contributes to improving the conditions of urban life such as:
• Water: The Orchid House collects and uses rainwater and dew for maintenance of the house,
5.2 Transportation
Our main strategy for efficient transportation is pre-fabrication. We designed the house as a module, which when combined with use of RFID, decreases construction time, increases quality control, lowers costs, and allows for easy assembly. Furthermore, because the Orchid House is designed as parts, if it ever needs to be removed from the rooftop – perhaps if the original building is being renovated or torn down – it is easily disassembled and moved to another location.
5.3 Affordability
Our plan for the Orchid House to act as a prototype for social housing includes making sure that it is not only affordable to maintain, but also to construct. The costs for building the Orchid House will be split into three parts: 30% paid by the government, 30% by the residents of the original building, and 40%
by energy serving companies (ESCO).
• Government: Since social housing is supposed to be the government’s responsibility, paying only 30% of the constructions cost will be an added incentive.
• ESCO: ESCO’s will be willing to shoulder part of the costs because their company mission is to pro-vide comprehensive energy solutions.
• Residents: Residents of row houses and duplex apartments will be willing to pay for 30% because they will receive rent. The costs for building an extension on the apartments is already low because the rooftop land is for free; when the 30% is further divided among the multiple households of the row house or duplex apartment. Also, because the houses are pre-fabricated and can be manufac-tured by parts, the more houses that are commissioned, the lower the cost.
6.0 Smart Living
“Smart living” in a home setting normally refers to the use of emerging technologies to enhance the quality of life, which might include designs to support physical as well as psychological comfort and convenience/efficiency in modern household activities. However, instead of planning a complete smart living system, which might cover designs that do not have a strong connection to the performance of the house, we focus on the applications of technologies in two directions:
1. To raise the comfort level, both physical and psychological 2. To support the awareness in the condition of living environment
Moreover, the designs we propose are centered on a key element of everyday life – lighting, and we believe that a “smart” design should be built on minimal elements.
6.1 Environmental Awareness
In addition to using technologies to endow a house with the capability to perform
automation which leads to lower energy consumption and higher comfort level, we believe it is important to support inhabitants’ awareness of the conditions of the environment they live in. It is the inhabitants who have the ultimate ability and right to actually change the environment and make it better. Therefore, developing designs to support conscious awareness of the environmental conditions is no less important than designs that reduce human efforts and enhance a house’s performance through home automation.
Our aim is to turn architectural space into an interface for information visualization. By visualizing information about environmental conditions - average indoor
temperature/humidity or overall energy consumption for instance - with key elements that constitute a living environment, it is possible to make inhabitants aware of the conditions without using conventional information interface such as display monitors or projections.
The developed design strategy is to use the element of “light” as the main means for such information visualization and we choose to visualize two major factors of environmental conditions: temperature and energy consumption.
6.2 Visualization of Temperature
For the factor of temperature, we use color to visualize it. The temperature is translated as the color of ambient light, arranged at the boundaries of ceilings, visible to the inhabitants.
Instead of using a simple analogy – the temperature of the environment corresponding to the temperature of light – the relationship between the color of light and the temperature of the environment is reconsidered based on the concern of psychological comfort. Therefore, rather than using a warmer color to indicate a higher temperature, a cooler color can be used to provide a psychological comfort during an overly warm day or in a warm space.
Consequently, changes in the color of lighting becomes readable and yet has effect to the level of comfort at the same time.
On the top of this basic strategy for the use of light and its color, we have developed two possible rules to guide the use of colors for ambient lights, and the two rules describe the change of ambient lighting colors as a response to the two possible factors explained below.
Outdoor Temperature:
The ambient lighting color changes according to the variation of the environment temperature in real time. We hope to let people feel more comfortable by surrounded in the different ambient lighting color. Warm colors give people the feeling of heat. Cool colors give people opposite feeling. If the outdoor temperature is too cold, the warm coloring lighting warms you up. On the contrary, if the outdoor temperature is too hot, the cool coloring lighting cools you down.
Average Temperature of Each Defined Space:
The ambient lighting in the house is divided into a few zones, and each of which can be controlled individually. The color of ambient lighting is determined according to the long-term average temperature in each defined space (living space or dining space, for instance). Consequently, the color of ambient lighting in a space may be distinguished from that in another space due to the difference in average temperature between the two spaces over a long period of time.
6.3 Visualization of Energy Consumption
The factor of energy consumption is visualized through the pattern of light and shadow generated by the indoor artificial lighting. Translating the abstract quantity of electricity consumption into a visual pattern shown on the surfaces of the interior spaces provides a
natural and ambient way for the inhabitants to be aware of the status of the house’s energy consumption. We propose to show such “energy pattern” on ceilings, and it is generated by a specially designed lighting fixture. The pattern is designed to have features of a flower, by which we hope to create a connection to the “Orchid House”.

The lighting pattern changes according to the electricity consumption in corresponding spaces.
Fig.5.2.2.1 Variation of color temperature for ambient lighting
Each petal of the “flower” corresponds to the energy consumption of each defined space, including living space, kitchen, and bedroom. The length of the petal represents the quantity of the electricity consumption. The more electricity used, the longer the petal is.

The “flower” represents the status of energy consumption. The length of each petal changes in response to the quantity of the energy consumption in each corresponding space.
6.4 Visualization of Outdoor Air Quality
Following the concept of social housing, visualization of environmental conditions may take place in an urban scale, in addition to the inside of each Orchid House. Similar to the idea of turning architectural space into interface for information visualization, the exterior of the house, as part of the urban space, can be used to convey information to users of the city.
Through the status of the house envelope, signified by the lighting, information about the city’s environmental condition at the location of the house can be made visible.
We propose visualization for the quality of outdoor air, which is a crucial information about the city-wide environmental condition. By controlling LED lighting on the exterior envelope according to the data of air quality collect from the weather station installed on each Orchid House, the exterior envelope becomes a signifying interface. The residents in the city can get a sense of the outdoor air quality by just looking at the houses. Lighting color is used as the way to represent the air quality. Blue color, for instance, tells that the outdoor air is in a relatively good condition. Red color, by comparison, may tell that the air pollution is severe.
6.5 Lighting Automation
In addition to the use of light and its associated properties as a way to visualize information about environmental conditions, as described above, the controlling of lighting, including both natural and artificial lighting, may be done automatically according to the lighting conditions and the presence of people in a space monitored by sensors. On the top of this automation, a manual override is also provided.
In general, automation of artificial lighting control is provided constantly in each space Fig.6.4.1. The lighting color on the envelope represents the quality of outdoor air
of the house. Automatic control for the combination of both natural and artificial lighting, in contrast, is provided at the bedroom and the living space. The adjustment of lighting is determined based on the scenarios of activities taking place in a space. The scenarios and rules of automation are presented below.
Living Room Scenario
To increase the convenience of the house, we integrate light with automatic curtain into the Living Room Scenario Control System. You can adjust both lighting and curtain at the same time by just touching the button on mobile device. There are two modes of the scenario control system, Default Mode and Movie Mode.
Bedroom Scenario
There are two modes in this scenario control system, “Wake-Up Mode” and “Sleep Mode”.
Similar to the living room scenario, in the bedroom scenario, the controls of artificial lighting and natural lighting, though the electric curtain system, are integrated and may be
automatically performed. The Sleep Mode is manually triggered through buttons or interface on the remote control device. The Wake-Up Mode allows the user to specify a wake-up time, when the electric curtain along with artificial lighting are controlled to provide proper lighting for the ease and comfort of morning wake-up.

6.6 Interface for Smart Living System
A controlling interface is provided based on a mobile device, a smart phone or a tablet computer. This gives users a convenient way to control the house when needed. The interface allows users to manually select the operations modes, as described above, or control certain devices such as lighting fixtures or electric curtains. Instead of using conventional 2D maps to organize
controlling functions, we may use a 3D model of the house as the basis of an interactive interface design. This leads to an interface through which navigation of location-based information becomes natural and understandable. Such a 3D interface serves two purposes. Firstly, it allows its users to locate device items to control based on their locations in the 3D model. Secondly, it presents information about environmental conditions based on corresponding three-dimensional locations.

Use mobile device to remote control the light and automatic curtain.
In Taiwan, the average temperature in summer is rather high. During this season, a thermal wall cannot offer any benefit to the house. Instead, it would accumulate heat and consequently lead to unwanted warmth to houses. Therefore, an additional controlling layer of sunlight to a thermal wall is necessary. Such a “skin” layer responds to the level of sunlight (or temperature) and changes it physi-cal status which results in a change of sunlight passage through itself.
Rather than using a conventional electrical-mechanical solution to achieve a layer of adaptive skin, which normally relies on complicated electrical-mechanical mechanisms including motors and gears, we are developing an innovative solution which is based on the use of smart materials. SMA (shape memory alloy) and thermo bi-metal are perhaps the most common smart materials available, and they have similar behaviors in terms of physical reactions to the temperature. We choose SMA as the major material to achieve kinetic movements in the building envelope. It has the ability to return from a deformed state (temporary shape) to their original (permanent) shape induced by an external stimulus (trigger), such as temperature change.
With smart materials, it is then possible to develop kinetic mechanisms which can perform designed movements without electricity. Combining such kinetic mechanisms with the design of building en-velope lead to a special architectural skin which adapts to environmental conditions. In our case, the
“smart skin” reacts to the temperature. As the outdoor temperature rises, units in the smart skin de-form to block partial sunlight, resulting in change of sunlight passing through. In this way, we expect that the smart skin can increase the performance of the thermal wall by reducing unnecessary heat in warm days. Other than this, it is generally a light-filtering layer of skin which can be fitted to other part of the Orchid House’s envelope.
7.0 Smart Skin
Temperature low (less shadowing area ) Temperature high(most shadowing area )
The key component of the smart skin – the kinetic mechanism with smart material – is designed as a unit with the shape of an orchid flower. Therefore, the smart skin appears as an array of orchid flow-ers that react to the sunlight. In direct sunlight which causes high temperature on the surface of the smart skin, the orchids bloom, and the petals become flat, allowing less sunlight to enter. On the con-trary, when there is less sunlight and the temperature is low, the orchids shrink, and the petals curl.
This allow relatively more sunlight to go through and reach the thermal wall. The heat stored during the day time is released during the night to keep the interior at a moderate temperature.
Similar device can also be used in indoor space, for instance, to replace automatic curtain. Instead of using electricity or human power to change the status of sunlight shading, this device enables archi-tecture to interact with the environment and climate. In addition to the thermal wall, this smart skin can also be installed on the 2nd floor west façade and under the north roof. This does not only offer sunlight shadings, but also provide an interesting pattern which gives the house a strong feature.

1.0 General Concept of the Project and Sustainability
Cities in Taiwan contain buildings with illegal structures. Everyone tries to gain a little more living space by encroaching vertically. Solar Decathlon is an opportunity to make people rethink what they have done, and what is crucial for a better world. Orchid House strives to solve problems such as electricity and water usage, along with social housing at once, in a smarter and more sustainable way.
2.0 Bioclimatic Strategies : Passive Design Strategies
There are three key bioclimatic strategies we have learned from Orchid’s eco-system:
• Indirect sunlight
• Good ventilation
• No excess water
To mimic the living environment, the Orchid House’s outer skin serves as a canopy to filter direct sun-light and reduce heat gain in the interior space. Large swinging doors opens up and let in cool air, which then go out through the operated windows on the mezzanine level. The sloped solar panel harvest rainwater which are stored, filtered, and can be used for irrigation.
2.1 Poject’s envelope
The Orchid House is the composition of two different type of volume, the exterior volume and the L-shape living space volume. This two different volumes play different roles in terms of climate control and spacing.
2.1.1 Exterior Envelope
The Orchid House’s exterior envelope consists with Makrolon® polycarbonate 40mm Low-E coated Inter-locking sheet from Bayer Material Science on general façade, automatic transparent glass louvers on south side, as well as high efficiency photovoltaic panel on the south facing roof.
Even though the Makrolon® polycarbonate 40mm is 55% transparent and its U-value is 1.1 W/m²*K, the installation process and supporting materials are far less than conventional glass curtain wall sys-tem. The Orchid House will already eliminate large amount of material usage and human resource by incorporating this system. Also Makrolon® polycarbonate is also 100 % recyclable, making it inherently sustainable.
