In 2003 – 2004, we participated in an open international architectural competition for an Egg Paper, we proposed to use paper as structural and cladding materials of an egg-shaped building. Our entity was selected as one of the five winners in 1st stage, but was not awarded as the winner due to the concern of constraints of budget and Chicago design guideline.

Due to the needs of industrialization in Chicago, the original marshy landscape of the Calumet Park was slowly manipulated, and over the 20th-century, a new landscape was formed. Today, contami – nation from abandoned industrial sites, hazard waste dumps and landfills continue to threaten these natural areas. Aggressive non-native plants, such as the Purple Loosestrife, are disrupting the natu- ral ecosystems that native animals depend upon. The perception of the Calumet Park is now one of a forgotten landscape.
Despite these changes, the land remains the home of a rare bird: the yellow-headed blackbird, although their population is declining dramatically.
The egg of the Yellow-headed Blackbird is employed as both a symbolic and generative force within the design. Ultimately the egg represents new life, bringing hope for the revitalization of the mistreat- ed land.
Recycled paper has traditionally been considered as a physically weak and forgotten material, simi- lar to how Calumet Park has been perceived as a wasteland. Through advanced technologies and ecosystem renewal, the “perceived weakness” of paper and the park becomes the strength of this project.

We propose to take advantage of the ecological value of reused paper: It is local, recyclable and inexpensive, and its production and treatment are not toxic. Advanced treatments also allows for a high fire resistance rating and structural stability.
We have accumulated much expertise in the techniques of paper architecture, and would like to dis- play the material qualities of paper tubing that have allowed us to design, detail and construct the Calumet Paper Egg.
Natural evolution has given us the inherently strong shape of the egg, easily resisting the elements through its aerodynamic shape.
We have proposed the structure as a mesh-shell system. The system is an independent shell structure that will support the outer skin, its own self-weight and additional structural live loads.


Title of the project:
The Sustainable Approaches for the Building Renovation in the Subtropical Region

Taking some Practical Projects in Taiwan as the Demonstration on the Environment-sustainability and
Occupant-healthy Benefits

Sustainable Development is a worldwide trend that analyzed from the lately international conference. It is in search of a system that can provide comprehensive performance..

Occupants in buildings which included the built-environment (illumination, acoustics, air quality, diet, thermal comfort, and social environment) reflect the situation which surrounds them by their mental sensations and physiological.

Taiwan develops a system of sustainable healthy construction that can provide comprehensive performance assessments of buildings in the different environmental scales: global, regional, local, interior and individual.

This paper takes some practical projects as the demonstration to
illustrate the design and technology approaches, integrated environmental harmony and occupant-healthy, in the hot- wet tropical area.

The basis of the environmental activity is the conscious objective of protecting the environment through the use of renewable resources within an eco-cycle that is sealed to the level possible, and the avoidance of environmentally destructive substances. The environmental policy and programme are based on the Natural Step concept.
One of the major objectives of the programme was to operate the facility using only renewable ener- gy, and that was achieved in September 1996. Only green electricity is purchased, while the rock- and marine-based heat pump systems with propane as refrigerant ensure space conditioning for the facility. Water for the pool and sauna is heated by means of heat pumps and solar panels.
The cold-rooms and refrigerators in the kitchen also utilise lake water as a cooling medium. Even the vehicle fleet and all gardening equipment operate on bio-fuels, apart from lawnmowers of which one is electric, one solar powered and the third – grass powered. Furthermore, a number of energy effi – ciency and saving solutions are in place.
The facility is equipped with its own water purification and sewage treatment plants as it relies on the water from Lake Malaren for its needs. Own sparkling water is produced on the premises to reduce the unnecessary transport. Waste is sorted to over 20 fractions and own compost plant has been cre- ated. The quantity of chemicals used in the facility has been significantly reduced and all products are eco-certified. All the raw materials, construction materials and consumer products are carefully selected and preferably eco-labelled.
The holistic environmental approach is especially visible in the new addition to the complex – the 16- room Malarblick building. It was constructed in a way to blend in with the surrounding nature, rock blasting was minimised and no trees were cut during the construction. The building is made of certi- fied wood and equipped with eco-labelled interior materials and furniture. It uses rock heat pumps with floor heating for space conditioning and solar panels for hot water production.
In general, all operations are designed to lead to continual improvement and to create the basis for preventive environmental programmes. This approach has lead to increased occupancy and higher profits.
The annual turnover was tripled in the last decade and the profits are at the level of 10-12%. This example clearly shows that environmental management does make a good business sense even in a highly competitive hotel market.

The World Tourism Organisation (WTO) describes tourism as one of the most important economic, social, cultural and political phenomena of the 20th century, while hotel buildings are outstanding landmarks at many destinations. The tourism industry has a dual relationship with the environment but has for many years claimed to be a “smokeless industry”. In fact, accommodation facilities inter- act with their environments during every stage of their life cycle, often negatively. Resorts are fre – quently developed in pristine and fragile ecosystems with little or no consideration for the local natu- ral or cultural environment. Many of the services offered by these establishments require the con – sumption of substantial quantities of energy, water and non-durable products. The resource-use effi- ciency of the many end-users in such facilities is frequently low, and the resulting environmental impacts are of significant magnitude.
While the average visitor may not yet be vocalizing clear-cut requirements for more sustainable practices in the tourism sector, the increasing environmental awareness among travellers is gradually translating into a growing environmental demand. In response, hotel compa – nies begin to consider environmental issues in their business practices.
Hilton International is an example of a worldwide known company that has put Corporate Social Responsibility (CSR) and environmental sustainability high on their priority list. A comprehensive environmental programme has been developed and implemented chain-wide. It is based on five cor- ner stones: Environmental Policy, environmental education (ecolearning), environmental reporting
(Hilton Environmental Reporting), a creation of sustainable facilities (Sustainable Hotel Siting, Design and Construction Guidelines), and internal communication (Hiway).
Most of these initiatives are based on a 10-year experience of environmental work at Scandic
(Scandinavian based hotel brand, and a part of Hilton since 2001). Scandic has introduced the con- cept of a 97% recyclable hotel room (eco-room), and developed its own Environmental Construction Standard (SERECS), listing materials that may not be used in their facilities, and specifying accept – able alternatives. Currently more than 10,000 rooms in the Scandic stock are 97% recyclable, while a number of hotels have been built or refurbished according to the eco-hotel standard. Between 1996 and 2003, energy consumption in the Swedish Scandic branch was reduced by approximately 19% on a kWh/m2 basis and 15% on a kWh/guestnight basis (with 1996 as a reference year). In the same period, water consumption was reduced by approximately 6% on a liter/guest-night basis, and the amount of unsorted waste decreased by approximately 48% on a kg/guest-night basis (NB: only properly reporting hotels are included in the analysis). Furthermore, 77 out of 123 eligible hotels
(62.6%) have been eco-labelled with the Nordic Swan Eco-label, the most demanding ISO Type I label for the tourism accommodation. The results of the environmental program at the Hilton level will be more clearly visible in a couple of years, but the right direction has already been established. This experience shows that the hotel industry can be an important partner in introducing sustainabil- ity into the built environment, and that responsible practice makes a good business sense.

Sustainability Concepts

The essence of a pavilion in which the constructive form gives a sense of scale and precise space of timeless light and shadows, poses in the tranquility and simplicity derived by the destined use of the edifying materials, in which structural steel greater accomplishment of industrial revolution-, rein – forced concrete stone of the XXth century- the glass sand of perennial beauty that reconciles matter and spirit-, emphasizes the exterior aspects of an enveloped plain geometry and conformed by vari- ous levels, like a pedestal, body and culmination.

These are assembled by various punctual elements constituted by the evoked materials: a stony solid anchor to the ground the work of art that erects above it; the visible structure that gives the rea- son to be-, materializes itself in columns that for reasons of equilibrium and function express the strength of the edified object posing on the land.

Finally, the lightness and transparency of the wrap emphasizes the swelled crystal plane that marks pavilion main entrance and limits from the immediate environment. An exterior ramp which ascend – ing sense avoids the eternal human wish to unravel the immemorial knowledge of life-, concludes in the last level where a delicate box of glass shelter the richness of the donated heritage by Vladimir Kaspe.
