The transportation system has been very well developed in Toyota. It is called as “Demand responsive transportation“.
Effect of Economic breakdown on Construction Industry
Posted by BenzuJK in Green Building on March 12, 2013
Poor Economic state of the World | Effect on Construction Industry and its prevention
Sudden Economic change is extremely bad for Construction industry of any country. The status of Global markets determines the behaviour of an individual country. For example, if the economy of United Kingdom is suffering due to employment problems in the country or financial crisis; it affects the whole of Europe. On the whole, the economy of Europe plays a great role in moving the market.
The first and foremost bad effect of the market would be:
Banks going bankrupt. Banks are the main sources of capital for major construction projects.
Construction industry is capital intensive.
Because of the banks going bankrupt, there is not enough capital in the market that could be utilized for new projects. Because of less money in the market, people are unable to afford luxury homes, offices. This has two major effects on the construction industry:
- Since, people do not have the money to buy buildings, Existing projects are stalled due to increasing raw material cost and decreasing real estate value. No more gigantic home loans available.
- After analyzing the scenario of the bad economic conditions of the market, the builders decide to scrap the idea of new constructions and decide to wait for the right time to start the project. This brings recession in the construction industry which affects architects, engineers and mainly workers badly.
Financial Crisis in the country will result in major construction firms going bankrupt which in turn would be responsible for the loss of thousands of jobs.
Is it possible to prevent this from happening? If yes, then how?
A new system of design is needed to ensure very low energy footprint, sustainable development and optimum use of local materials.
A renewed focus is needed on Green building Design…
Growing Need for Environmental Sustainability
Posted by BenzuJK in Green Building on October 29, 2011
Chronic Need for Environmental Sustainability
Everyone is aware of the fact that the life on earth is degrading day by day. The quality of life on earth has gone from best to worst in the past 150 years.
For people who do not agree with the concept of Sustainability
The concept of sustainability is brought up for the betterment of human species and not for the earth. The Earth can survive without humans. Sustainability is for us to survive on earth.
The video illustrates the story of our Mother Earth or rather I should say “Sad story of Earth”….
Earth was beautiful and Green before humans started using Earth’s resources ruthlessly… The earth is now in the devastated condition and if this continues for the next 50 years, it will bring with it the end of Human life on Earth by the next century.
We should all work towards making our environment green and sustainable because we are the ones who are responsible for getting it into such a bad ruined state.
Aerocon Blocks – the new Green Generation Blocks | Sustainable Building Material

Aerocon Blocks | Green Building Materials
Aerocon Blocks are an innovative product in the green building revolution. Aerocon blocks are the new blocks in walling materials, substituting conventional and environmentally unsustainable materials like clay bricks, concrete and Hollow blocks.
Aerocon blocks are an Autoclaved Aerated concrete blocks used in the construction of walls. The raw materials used in the manufacture of these blocks are environmentally friendly and are certified green products. Flyash is also used as an alternative building material which is a waste from thermal power plants.

Since, these materials are light weight with high thermal insulation, they are highly fire resistant. These blocks save water during construction and ensure long term sustainability of the building. These blocks have been used in wide range of constructions which include residential, commercial, hotels, hospitals, schools etc.
Autoclaved Aerated Concrete (AAC) – A New Green Building System

Autoclaved Aerated Concrete (AAC) | Efficient Building Systems | Green Material
Autoclaved Aerated Concrete (AAC) was developed in Sweden in the late 1920s and has been used successfully in a variety of applications in commercial, industrial and residential construction. AAC is a lightweight, high strength building material and is produced in a variety of forms from blocks, to structural floors and wall panels.
AAC is credited by LEED (Leadership in Energy and Environmental Design) and USGBC (US Green Building Council) as an “green” alternative to traditional construction materials. Indian Green Building Council (IGBC) recommends its use in India.
AAC consists of 80% of air. It is manufactured by combining silica in the form of sand or recycled flyash, cement, lime, water and an expansion agent – aluminium powder and paving it into a mold.

Structurally reinforced AAC products like lintels or roof panels, steel rebar or mesh are also placed in the mould.
When added to concrete, the aluminium powder reacts with the silica, resulting in the formation of millions of microscopic hydrogen bubbles. The hydrogen bubbles cause the concrete to expand to roughly five times its original volume.
The hydrogen evaporates and leaving a highly closed cell aerated concrete. It is then cut into blocks or panels which are then steam and pressure cured in an autoclaved. Using AAC is very advantageous because it is environmentally friendly qualifies as a ‘green’ building material from manufacturing to recycling.
All the waste material like trimmings, rejected units are all recycled and hence there is zero wastage. All the waste on the sites is crushed and safely used as a fill or buried shallow underground. Spread AAC dust on the lawn serves as a great lime supplement.
AAC is so lightweight, it weighs 1/5th of the weight of the standard concrete, which results in lower transportation costs, faster work-flow lower material handling costs etc. AAC is in ‘ready to build’ material, requiring no onsite curing time. It has unparalleled workability because it can be sown, drilled, nailed, screwed and milled with common hand tools. AAC openings are easily and alternately cut.

Aayam in Sanskrit means dimension, and the presented design has provided innovative solutions in all the dimensions of creative world.
The entire building has been made in order to preserve the landscape and adapt suitable style pertaining to the topography. By determining the quantity and quality of light entering the spaces, they have eventually taken on greater reality. The galleries are woven into a modulated space, born of light and geometry.
IPSA - Indore (Sustainable Green Architecture)
The design is a centre of culture that is rooted in the region and reflecting contemporary art and architecture at the highest level that have come together with nature. The core of the annex is open to sky and the rigorous used of a geometric vocabulary. A reflection of land art with pure modernism, the convention centre is rooted to traditions and mirrors ideas if the youth of India.
Redesigning Institution as a Convention Centre
Posted by BenzuJK in Green Building on May 29, 2010
Perception
Convention centre are often a means to represent ethos of a particular country, perhaps, even an expression of myth of a particular community and their traditions. A place which can provide the essential, platform for exchange of ideas. In an urban context, where cities witness rapid growth and development, a convention centre caters the need of stage where new innovative ideas can be sold, shared, felt and experienced. This can be in the form of exhibitions, workshops, seminars, conferences serving the purpose of both the industrialist and the consumer. The best example is the Pragati Maidans.
Redesigned Elevation of the Convention Centre
Case Studies
Pittsburg Convention Centre
The largest first gold LEED certified building located near the Alleghemy river which was also appreciated for having the concept similar to that of the suspension bridges in that city. The planning thus offered dramatic vistas overlooking the river onto the historic downtown.
