Sustainability Efficiency in Architecture

Creating Self Sufficient Structure
Utilizing city waste to build structures that generate energy for itself and the surrounding area. The self-sufficient buildings and blocks are the new paradigm for the city's construction. For constructing buildings and blocks that are self-sufficient we have to create new methods of architectural thinking in which the metabolism of the buildings (production and management of matter and energy cycles, water and waste, information, etc) is designed in a form that is integrated with the natural structure and its function. (HMC Architects, 2017)


Green Buildings
A ‘green’ building is a building that, in its design, construction or operation, reduces or eliminates negative impacts, and can create positive impacts, on our climate and natural environment. Green buildings preserve precious natural resources and improve our quality of life. 
Any building can be a green building, whether it’s a home, an office, a school, a hospital, a community center, or any other type of structure, provided it includes features listed above. However, it is worth noting that not all green buildings are – and need to be - the same. Different countries and regions have a variety of characteristics such as distinctive climatic conditions, unique cultures and traditions, diverse building types and ages, or wide-ranging environmental, economic and social priorities – all of which shape their approach to green building.

Materials Availability
Traditionally people use earth bricks, concrete, and wood in construction. Many have been, and continue to be used in everyday construction, meaning the continued destruction of trees for timber, and the mining of resources to produce cement for binding sand, gravel, and bricks. For a better world, there are new processes, and sustainable as well as green building material alternatives that can be used in construction today. (Conserve Energy Future, 2022)
At present the demand for a more sustainable way of building is no longer a matter of personal choice, and the sector has been now regulated for the purpose of implementing measures that improve the infrastructures´ and buildings´ environmental behavior. We are wrong to consider vehicles as the only polluting factors, as buildings consume 20 – 50% of the physical resources, according to their environment. The building trade is a great consumer of natural resources such as wood, minerals, water and energy. In addition, buildings, once built, continue to be a direct cause of pollution because of the emissions produced in them or their impact on the ground. 
A sustainable architecture takes account of the use of resources (energy, natural resources), their environmental impact and the specific risks to people´s safety. (Acciona, 2019)
In building, environmentally-friendly materials (also known as green building materials) are those in which, for their production, placing and maintenance, actions of low environmental impact have been performed. They have to be durable, reusable or recyclable, include recyclable materials in their composition and have to be from resources of the area where the building activity will take place –they have to be local materials.
