Sea Train House 2003 Sustainanble Architecture……an introduction Los Angeles, California * Man has always depended on nature for it’s needs; taken so much yet redeemed so very less. To be true man has always robbed nature. * co-existence between nature, man and man-made structures a must. *The mutations in interpersonal relationships and intergenerational gaps, technological development, mass migrations and globalization have transformed the spaces in the urban landscape. a city with high inputs (of energy,food etc)and high output (thermal output,sewage etc) is less likely to ‘hold’ and thus keep up and is less sustainable (derived from sub-[under] and tener-[hold] means to hold under) than a city with less input and output. Need for sustainability : * meeting the needs of the present without compromising the ability of future generations to meet their own needs. * Technological advancements, sophistication, infrastructural conquests, never thought before designs, well…. a never ending list fuelled to excel . This is what we see today. *Due to all this we have a sorry loser in the form of nature. It has been receiving unkindly blows every time – ever decreasing resources, increasing pollution,congestion and all. * these days an architect can’t turn over a mossy green rock without finding the word sustainability written under it!! Strange it may seem!! But this seems to be the only option whereby humans and other forms of life will flourish on the planet forever. * inadequacies and the negative impacts of past choices and related mechanisms. Measures for Sustainability * Sustainably designed buildings aim to lessen the impact on our environment and the building’s occupants through energy and resource efficiency. * merging of innovation with technology, sustainability, function. * Architecture a hope for sustainability. •1) Modular Building Blocks2) Reconfigurable Spaces •3) Decentralised urban plannin4) Passive Energy * considerations like feasibility, affordability,materials etc Kenectic energy * Reduce pollutants, recycle, reuse when possible * Provide sustainable, easily available building materials where possible blending it with the vernacular architecture of that particular place. * Reduce the stress on nature and opt for alternate means. modular housing * Earth provides us with a finite amount of natural resources * Should be used in proper way * When selecting products and materials to use in your home, look for ones that have: High levels of: > Renewability, Reusability & Durability Low levels of: > Embodied energy, the energy required to extract, process, and transport materials > Environmental impact, the negative effects on outdoor and indoor environments Sea Train House 2003 Tucson Mountain House 2001 Los Angeles, California Tucson, Arizona * Situated at desert site * Its rammed earth wall is a mixture of desert soil and portland cement * Walls are 2 feet thick and 16 feet high * Ideal match for desert conditions * Structure – absorbs heat at day time and releases at night Sea Train House 2003 Los Angeles, Sea Train House California 2003 Los Angeles, California * wedged between a scrap metal yard and an industrial building * completely recycled from salvage materials * The roof insulation circulates cool air * living area features a cascading waterfall Sea Train House 2003 Great (Bamboo) Wall 2002 Los Angeles, California Commune by the Great Wall Shuiguan-Badaling, China * single building material: bamboo * add rhythm and texture to façades. * easy transfer of light and breezes * Luxurious modesty and eco-efficiency do not have to be mutually exclusive. Sea Train House 2003 Reconfigurable spaces Los Angeles, California * It allows a flexible adaptability * A specific module is selected * Containing all the necessary electrical equipment * Attached to each other with a seamless flexible connection * Attached to the corridol ,shared walls (provides the capability of expansion to a shared common place ) * A systemic modularity allows infinite shapes and combinations. Decentralized urban Planning The primary motivation of the design lies in creating a design solution that is flexible and adaptive at any scale, and at instances, responsive and intelligently active with respect to the changing individual and climatic contexts. Accordingly, the goal for the sustainable urban place was to provide a framework for flexibility that can be configured and reconfigured on two scales. Firstly, to satisfy the immediate desires of the community and users with the capability of adaptability and expansion to meet the changing needs of the urban place programmatic spatial requirements, and secondly on a local scale to optimize the building for changing environmental conditions. Such adaptability then aims to meet the changing needs of the users and their activities/environment for comfort and optimum spatial efficiency and thermal conditions. Decentralized urban Planning new kinds of built from based on factory-produced materials, with individual lighweight transportable homes located in natural countryside, thus creating a “townless, fully decentralised, and even populated country” . metropolitan region are not a harmonious equilibrium of city and surroundings, but as fundamentally shaped by the actual behaviour of individuals. whether to concentrate development at higher densities within the existing urban envelope, or whether to encourage decentralisation to new areas or satellite communities. residents look to their immediate surroundings rather than to the city for their jobs and other needs.The dispersed settlement structure is truly multicentered. Decentralized urban Planning Decentralization destroys both “nature” in its natural form and “society” in its civil form. metropolitan region are not a harmonious equilibrium of city and surroundings, but as fundamentally shaped by the actual behaviour of individuals. “The urban field as an artificial environment”. The nature of the city is that it turns nature to the city. Spatial balance as a key concept amounted to a decentralized urban system based on three basic principles: these were identified as urban spread, the development of corridors and the appropriate use of energy and transport. Decentralized urban Planning spread cities seem to have more advantages than the disadvantages because of the following reasons: 1. Compact cities would consume the open spaces making our cities’ environmental quality poor; 2. The compact city policy would result in the neglect of our rural communities.although it makes up a fraction of the population, it controls the policies for the entire archipelago. 3. The compact city would cause congestion, increase pollution, loss of space and reduction of privacy; 4. Social gaps would grow as a result of high cost of accommodation in the city centers and; 5. Compact cities mean massive financial resources.Compact cities maybe more efficient in terms of transportation and energy consumption. But if we are to scrutinize the negative effects of the “compact”loss of rural to urban migration and consequently the slow development of the rural communities, we can see that it outweigh its benefits. Energy Passive Kenectic energy Due to the incident solar radiation in the courtyard, the air in it becomes warmer and rises up to replace it cool air from the ground level flows through the covered opening of the room. Thus, producing the air flow. The roof surface are sloped towards the interior courtyards. Time cools air. It sinks into the courtyard are enter the lower spaces through vents and low level openings and leaves through high level opening. Courtyards with cut parapets permit coo lair to flow into the building at night. Energy Passive Kenectic energy Traditional clear storey windows with projecting shade provide diffuse light to create uniform ambient lighting in interiors. It helps in producing an effective stack effect for better ventilation, prevents glares and thereby lieat gains. One of the common passive shading device feature is a balcony whose upper portion is effectively used as a winter living space and at the same time provides edequately shaped buffer spaces below to create comfort condition during summer. As the temperature of soil ant bout six inches or more below the surface of the earth, if a pipe is buried underground at this depth atmosphere’s air is passed or circulated through it. The air will lose or gain heat depending upon whether it is.

The low pressure at this point vents the hot air under the roof. In this way air is kept circulating through the room under the roof, air vents are usually placed over living rooms, often with a pool of water directly under the vent to cool the air which is moving up to the vent by evaporation. In addition to shading, this arrangement provide an increased surface area for radiative emission, and an insulating cover of still air over the roof, which impedes heat flow into the building white still permitting upward heat flow at night. Terrace garden should be provided to reduce heat gain through exposed roof. Curved roof has a larger convection heat transfer area and transfer heat more efficiently than a flat roof therefore, a curved roof is more easily cooled.
