Before starting to talk about this interesting topic, we must be fully aware that all our work and efforts on the land of our planet, whether good or not, will always return to us, even if later, with its results that may be useful if we provide what suits our land or it will have negative effects on us, and it may cost us everything that is precious and beautiful on the surface of this planet.

With this topic, we will address the following points that we must take into account to live within a sound architectural environment and start talking about the components of green buildings…

1. Energy efficiency and renewable
2. Energy Water efficiency
3. Environmentally preferred building materials and pacifications
4. Waste reduction
5. Reduce toxins
6. Air quality indoors
7. Smart growth and sustainable development

Rethinking in the energy sector is the key to tackling carbon emissions.” Almost every country in the world has pledged to reduce its own carbon emissions through the Paris Agreement, and the energy sector makes up a significant portion of nearly every country's emissions. Overall, energy-related emissions account for two-thirds Global Greenhouse Gas Emissions today in order for the world to avoid catastrophic climate change, countries need to strive to decarbonize energy", says Dolph Gillen, Director of the Center for Innovation and Technology at IRENA: “We have found that renewables and energy efficiency can work together to provide more than 90% of the required mitigation in the energy system by 2050.” Decarbonizing energy is vital to put the world on the path to meeting the Paris Agreement.

We can say that real environmental and social benefits can be gained by promoting synergies between renewable energy sources and energy efficiency. Reducing air pollution - the real killer - is one of those reasons. Another recent study showed that, for example, nearly 13,000 lives were saved in the United States by deploying more solar and wind power. Therefore, the use of toxic energy in modern buildings, regardless of their areas and sizes, we extend our hand to save ourselves, as it is a societal responsibility that must be taken into account, especially when talking about the establishment of entire cities that we must need with the increase in population that requires urban expansion.

Instead of standing still without solutions and trying to build hospitals with the most luxurious technology and modern designs, we have to find a solution to the basic problem that might prevent these patients from entering hospitals in the first place.

Water efficiency

Water efficiency reduces water wastage by measuring the amount of water required for a specific purpose and the amount of water used or delivered. Water efficiency differs from water conservation in that it focuses on reducing waste and not restricting use through the use of modern technology concerned with this issue and taking it into consideration during the initial study for the design of urban facilities such as towers, transport stations, hospitals and other residential buildings, as the construction sector is one of the largest consumers of the Earth's fresh water supply.

Environmentally preferred building materials and specifications

Through the use of technology by those interested in preserving a healthy planet, one of them is the Athena Institute, which has introduced the so-called "Environment Impact Estimator" that allows construction teams to assess the environmental impacts of a variety of building types. This program provides evaluations for more than 200 products, and the launch of the National Program for Energy and Water Demand Management in the United Arab Emirates, in cooperation with strategic partners in federal and local government agencies and the private sector. The program had an impact on reducing consumption and demand for energy in the three energy-consuming sectors with 40% by 2050, and one of these sectors is the construction sector, which in turn leads to the preservation of natural and environmental resources.

Waste reduction

Waste reduction is a set of processes and practices that aim to reduce the amount of waste produced. By reducing or eliminating the generation of harmful and persistent waste, waste reduction supports efforts to promote a more sustainable society. Determining the extent to which an existing building is to be demolished or reused is often a major design decision. Developing a waste management plan that describes materials that will be reused on-site or separated for off-site recycling is a very effective way to reduce waste going to landfill.

Air quality indoors

This is often associated with the identification of lighting components and low-mercury buildings, and zero-VOC paint is an important reason to reduce indoor air pollution. In addition, the use of toxic-free paint for furniture or any type of wood found in the decorations of villas, palaces or any of the apartments has a significant impact on maintaining the purity of the air. Of course, studying the movement of the incoming air and the surrounding environment is necessary and imperative to maintain a healthy environment.

Based on the principle that about half of the energy consumed by humans is inside buildings, and this shows the huge amount of energy that can be saved if solutions that contribute to reducing cooling costs are adopted.

Heating, air conditioning and lighting in buildings, in addition to finding aesthetic solutions, add a beautiful and different architectural touch to the buildings. Which we can later call smart buildings, and this label is not new. It was launched in the eighties of the last century in the United States of America and defined as buildings in which multiple systems are integrated with high efficiency to manage resources and capabilities in order to maximize technical performance, increase revenue, rationalize operating cost, and achieve flexibility.

The environmental concept of design seeks to contribute to the regional and international effort to reduce the negative effects resulting from the use of energy resources. So with regard to the design and architecture sector, it was necessary to think carefully about the topic of the smart home by placing sustainable development and sustainable architectural design at the top of the list, and there are architectural structures that were designed and implemented In this form, as the dwelling of the heliotrope, inspired by the name of the flower that faces the sun during its movement. 

The Al Bahar Towers in Abu Dhabi is a perfect example of the splendor of green architecture.

As a summary of what was mentioned, the concept of green architecture is an architecture that results from its environment and is responsible for its direction, that is, an architecture that respects the resources of the earth and its natural beauty. It is an architecture that provides the needs of its users as it leads to maintaining their health, feeling satisfied, and increasing their production and this is done by taking care of implementing the proven strategies for environmental sustainability mentioned above.

Buildings must be designed in a sustainable manner aiming to reduce its negative impact on the environment through the efficient use of energy and resources. This is because buildings are one of the biggest causes of damage on Earth, as the pollution resulting from heating and cooling the internal environment of buildings is greater than the pollution resulting from car exhaust, even in the United States. In addition, the building materials industry consumes huge energy and non-renewable resources.
