With so many ecological concerns coming up every year, the need for the hour is to grasp the concept of Eco-friendly and sustainable architecture. The dawn of this green architecture came from the Eco-build in London, Cannes and the Earth Day and it seems to be develop rapidly in the developed countries. Green architecture can change the world. With rapid advancements in the field of Eco-friendly products, there is a huge demand for making buildings and construction techniques more greener and sustainable and less harmful for Earth. The world has grasped this idea very well. The need for new techniques and materials which can be easily recycled are taken into consideration. Here’s showcasing 5 trends in green and sustainable architecture which is a focus of attention amongst Eco-designers.
1. Vertical Farming
With an expected increase in population to 9.1 billion people within the year 2050, feeding all the people around the globe is a cause for major concern. Food production needs to increase by 70%. This would mean having higher crop yields and expansion of the area cultivated. However land available for cultivation is not evenly distributed, while others are suitable for cultivating only a few crops. Thus architects have been designing buildings where one can grow crops on all the edges surrounding the building. This gives more area for cultivation and helps solve the expansion crisis. The vertical farms can be integrated with residential buildings too, with farms being set up on the external periphery of the buildings. This provides a clean environment for the residents to live in.
Straw is a sustainable material which can be used as a building material. Many designers and builders today are making use of this natural material to make phenomenal designs which are Eco-friendly. These buildings can be made from prefabricated panels using straw. These panels can be assembled from locally sourced star which can be fit into the panel frame made from timber. This production style helps save money and energy and decrease build times and carbon emissions. Electricity can be generated by photovoltaic and solar thermal panels and the extra electricity can be sold to the electricity grid. The homes made by straw would be considerably cheaper, as straw is a product which is available in vast quantity. This low cost makes it more popular to the general masses.
3. Phase change materials (PCMs)
Phase change materials are used to store both cooling and heating energy. These new age materials can be embedded in the ceiling and the wall tiles from where they absorb heat to keep the space cool and reduces the need for air conditioning. These Phase change material tiles have micro capsules made of a special wax which is developed to contain heat during the day. Some companies selling phase change materials claim that using the material reduces temperature of your indoor surrounding by almost 7ºC, hence reducing air conditioning costs.
4. Bees and biodiversity
Bees are an integral part of our biodiversity. A small garden or a rooftop is all that is required to keep bees. They help in making delicious honey from plants and flowers in your gardens, parks and the tree lined roads. It is important to make an environment in cities that safeguards wildlife and also helps in further diversity. By incorporating biodiversity into architecture, we can make a cleaner and greener world. Hence keeping bees and making bee hives are an important step that needs to be taken to ensure a cleaner, greener environment. In London, vast number of bee hives have been created on the roof tops of buildings, attracting many bees.
5. Sustainable materials
Apart from the many products used in construction made from recycled materials, many researchers are looking at the construction industry for other sustainable materials from other sectors which are rarely used in design and construction.
Thousands of samples have been taken from countries all over the world. These selected materials provide an Eco-friendly alternative to other resource hungry materials which generally have many by products which are harmful to the environment. These samples are being studied and their properties are made good use of. So it is essential that we find sustainable materials which can be easily recycled and are durable and appropriate for construction.
