A system is self-sustaining or self-sufficient if it can maintain itself by independent effort. The system self-sustainability is the degree at which the system can sustain itself without external support and the fraction of time in which the system is self-sustaining. Self-sustainability is considered one of the "ileitis" and is closely related to sustainability and availability.
Maximal independency was a driving factor for conceptual ideas applied to provide good use of the land on giving project and preserving ecological sustainability of the design area. Analyzing plan of proposed plot of land for creating self-sustainable township, it came first to attention that it is located in Newtown, Papua New Guinea at suburbs of its capital Port Moresby. The plot is adjacent to Sir Hubert Murray Highway on East and South-East side and rest is surrounded by land used for agriculture and proposed land itself was used also for agriculture.
The location and surroundings frame the development in a low populated area, economically depressed with tropical climate zone. Design focus was extended to include an integrated solution taking into consideration the challenges of this whole plot of land with its surroundings. Based on the pre-existing scheme given by client, an evolutionary development plan was put forward based on main principles of ecological friendly, totally walkable community:
1. This town is for both life and work, providing healthy, comfortable and efficient work and living environment.
2. Town must be completely self-sufficient by use of renewable energy resources such wind, solar energy and geothermal energy produced by wind generators; solar panel ; geothermal boreholes and created waterfalls for electricity generation (photovoltaic cells), and for heating of water which is used for domestic needs and for heating (solar collectors).
3. Use of energy saving, solar, wind, water and geo-thermal power; autonomous life support systems.
4. Automobile totally free town with underground parking on town borders at exits from highway and golf cart depots; electrical car garages; town bike stands; horse burns on the ground level. Additional public transportation (bus, taxi, mini-bus) to and from site.
5. Main venue elevated above the ground for pedestrians and local eco-friendly transportation such a private and town rental bicycles, horse carriages, golf carts, electrical cars and minibuses along south, west and north plot property lines.
6. All areas of new sustainable town are linked by wide green landscaped corridors along improved bed of existing creeks with gardens and boardwalks.
7. A new centrality for the area around Central Park with pond system; educational, religious and sport complex; performance center; public gardens, open venues; playground and boulevard.
8. Low rise housing, 2 – 6 storeys, not higher than trees with passive light and air flow, built from environmentally friendly recycled construction materials with possibility of intensive private and public agriculture and gardening, using recycled greywater. This concept proposes a different method of densification; one that is built on a low rise, livable, high occupancy design directive through an intensive "carpet-style" site plan, bringing people in touch with the ground plane, something typically lost in high density, high rise developments. The concept responds to the low-rise, high-density challenge by creating a modular, carpet style scheme that rises off the site between 2 and 6 levels in height, allowing residents access to the physical ground, or the intensive network of "park like" green promenades that expand across all residential areas.
9. The architecture of buildings and structures designed in harmony with surrounding environment.
10. Living environment socialization and education for residents and children.
