Applications of this philosophy range from the microcosm — small objects for everyday use, through to the macrocosm — buildings, cities, and the Earth's physical surface.
APPLIED TO ARCHITECTURE
Sustainable design seeks to reduce negative impacts on the environment, and the health and comfort of building occupants, thereby improving building performance. The basic objectives of sustainability are to reduce consumption of non-renewable resources, minimize waste, and create healthy, productive environments.
Sustainable Design Principles
Low-impact materials, Energy efficiency, Quality and durability, Design for reuse and recycling, Design Impact Measures for total carbon footprint and life-cycle assessment for any resource used are increasingly required and available, Sustainable Design Standards, Biomimicry, Service substitution, Renewability, Healthy Buildings, Robust eco-design
b.New Orleans sustainable design competition
Fig. 1 Looking northeast to mixed-use building along River Boulevard from levee
Litmus Architects was one of 11 runners-up featured in an exhibit at the Ogden Museum in New Orleans for the Global Green USA competition to design a sustainable community in New Orleans, aided by the financial assistance and star-power of none other than… Brad Pitt.
The Holy Cross neighborhood of the Lower Ninth Ward was the site of the competition, where multidisciplinary teams were asked to design six single-family houses, a mixed-use building which included apartments and community services, and the site itself. Though entrants were encouraged to think beyond the site, balancing sustainability with affordability was a key component of the competition.
Six finalist entries were announced today on NBC’s Today Show, which will be further refined over the next month.
The entry by Litmus Architects stressed the site’s adjacency to the Mississippi River by locating the mixed-use building at the southern edge, creating a River Boulevard and open-air amphitheater (Figs. 1,2) at the levee for concerts and parades.
Fig. 2 Partial south-north section through site. From left to right - levee/amphitheater; River Boulevard; mixed-use building (in color); the Commons with playgrounds, gardens and wetlands; houses.
The organizing strategy for the site (Fig. 3) was a north-south grid of walls that could rise at the north end to become pre-engineered foundations for houses (saving the owners time and money), define the playgrounds, wetlands and public gardens (Fig. 4) at the heart of the site, and extend south across the levee into the river to become breakwaters to control erosion of the banks.

The entry also concentrated on learning from the inside/outside spaces often seen in New Orleans and the low-tech ways of shading places, keeping out the sun in summer while admitting natural light and breezes. Some striking spatial compositions resulted, such the internal courtyard in the mixed-use building with the upper floor apartments linked by bridges

c.Multistory building in Singapore will restore bio diversity
With cities and urban locations turning into jungles of concrete, sustainability and adaptability are the catchwords of modern designers. Keeping ecological improvement in mind, a Malaysian architecture firm has come up with a marvelous design, which surely will be a landmark in the field of architecture. Hailed as the EDITT (Ecological Design In The Tropics) Tower, the pioneering structure is planned to restore the bio-diversity of the local ecosystem. Set to build in Singapore, the 26-story tower will accumulate rainwater and incorporate a gray-water system, which will fulfill over half of the water requirement for plant irrigation and lavatory flushing. Residents and visitors will be able to visit the gardens through ramps that connect the EDITT to adjacent shops and offices.
Design Status:
The EDITT Tower is currently lined up for construction in downtown Singapore.
Usability:
Covering half of the surface area in organic local vegetation, the EDITT Tower also features photovoltaic panels in about 855 square meters of area that will fulfill about 40% of the energy requirements of the structure. If required, there is also the scope for an energy plant that will convert human sewage into bio-gas. With a number of movable or altogether removable walls and floors, the innovative tower affords a lot of space and scope for future modifications.
Designer:
The EDITT Tower is designed by TR Hamzah & Yeang, a renowned Malaysian architecture firm, and sponsored by the National University of Singapore.
a.Sustainable Style: Prefab Futuristic Green Home Design
Like any good sustainable design the zeroHouse has all kinds of green bells and whistles, but it does something that many eco-friendly designs fail to do when they get too carried away with sustainability: it also looks extremely cool. Green home design strategies are balanced with beautiful prefabricated materials, colors and finishes.

Green home design strategies are balanced with beautiful prefabricated materials, colors and finishes.
The zeroHouse collects solar power and can store energy for up to a week’s worth of use. It also gathers rainwater in an elevated 2700 gallon cistern so that gravity can do the work rather than tapping into the power supply. Waste is processed into dry compost below the house. Insulation and day-lighting are used to balance internal temperatures and maximize thermal performance.
The house has everything needed for a short-term getaway or long-term residence, including a living room, kitchen, bathroom, two bedrooms and an elevated, covered deck. Everything in the house is automatic, with master controls tied to a central laptop computer.
This seems to be more and more the trend within green design: building homes that take maximum advantage of versatile materials, prefabricated parts, energy indepedence and other sustainable design strategies while maximizing style, comfort and livability.
