New revolutionary Ecovillage development in the UK | Lammas
It is one ecovillage in the UK to attain prospective planning permission. The permission was achieved in 2009 after three years of planning campaign (1). It is situated in Northern Pembrokeshire, Wales. It consists of only 9 households spread over an area of 75 acres. The concept of the development of ecovillage was to provide the residents with a sustainable lifestyle. The aim was to help residents learn to grow their food, fulfill their own water and energy needs without depending on mains (2).
Locally available materials have been used for construction. The materials include local timber, straw bale insulation and locally sourced aggregate. Green techniques have been incorporated in the design of ecovillage. Use of masonry stove, passive solar heating and a wood fired kitchen. Department of Energy and Climate Change funded the ecovillage project (3).
The project was designed in a way that it could be replicated anywhere across the country. Each household purchased a 1000 year agricultural lease from the organization that provides them security and autonomy. They employed systems of Permaculture which were used in Australia in 1970s. These techniques helped in maximizing the land productivity. It emulated the natural ecosystems, increase in biodiversity in the local area. It also helped in increasing the productivity organic food. There was a considerable decrease in the levels of carbon pollution (4).
Sustainable City in Japan – Toyota
Toyota, a city in Japan has been working to achieve ecological sustainability and has been taking effective measures to strive towards it. Toyota is called the eco-ful town. It has earned its renown for building a life sized model of sustainable living and demonstrating it successfully. Use of renewable energy and achieving energy efficiency has been its prime goal.
Design of Roads in Toyota
The roads laid in the city of Toyota have been paid special attention to. The roads are coated with water retaining and thermal insulation substances to minimize heat emission.
The transportation system has been very well developed in Toyota. It is called as “Demand responsive transportation“.
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…
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 | 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.
