Population growth, increasing development of cities and subsequent destruction of green spaces and finally an increase in air pollution and global warming, have increased the need to find ways to coexist with the natural conditions, conserving energy, preventing land pollution, protecting the environment and reducing energy consumption. In order to increase green space in urban areas and greater energy efficiency in buildings, especially in cities, attitudes and new approaches of modern architecture are one of the strategies toward green architecture which has attracted the attention of many contemporary designers and architects in the world in recent years. This architecture is derived from the concept of sustainable development in harmony with environmental compatibility in order to meet the needs of people, step for the survival of human interaction and environment. To create green buildings, after examining the need to use them, first, we must be familiar with the principles of ...

Nanocoatings are regarded as the most promising high-performance materials for construction applications. Thanks to their self-assembly effect, they represent remarkable characteristics against environmental agents compared to conventional coating materials in construction industry. They also show high performance in contradiction of energy efficiency, CO2 emission, and the air quality improvement. In this study, a review of nanocoatings on the basic reaction mechanisms and materials, in general, and for building application, in particular, is presented.

One of the most lucrative renewable energy sources for supplying energy in future decades is the solar energy. Solar energy can be utilized through both active and inactive systems. Inactive solar systems are the ones which collect and store solar energy without the use of energy-consuming devises such as pumps or controllers, so that the energy can be used at the time of need. This causes the amount of energy consumption in different parts of a building to reach their point of minimum. There are different methods for the utilization of the solar energy in an inactive way, namely solar windows, solar greenhouse method, Trombe wall and aqua wall, atriums, and pools on the roof tops. In this paper, the most common methods of using solar energy in inactive ways, which are atriums, Trombe wall, and solar greenhouse are analyzed. The method of the research is descriptive-analytic so that with better knowledge, modern designs can gain full benefit from these techniques.

Population growth, increasing development of cities and subsequent destruction of green spaces and finally an increase in air pollution and global warming, have increased the need to find ways to coexist with the natural conditions, conserving energy, preventing land pollution, protecting the environment and reducing energy consumption. In order to increase green space in urban areas and greater energy efficiency in buildings, especially in cities, attitudes and new approaches of modern architecture are one of the strategies toward green architecture which has attracted the attention of many contemporary designers and architects in the world in recent years. This architecture is derived from the concept of sustainable development in harmony with environmental compatibility in order to meet the needs of people, step for the survival of human interaction and environment. To create green buildings, after examining the need to use them, first, we must be familiar with the principles of green architecture and then proceed to the design and construction. This paper attempts to investigate different parts of a building (green views, indoor and outdoor living walls, green walls and green roofs area), due to the possibility of planting and principles of construction. Then by examining samples of  green buildings in the world today and expressing characteristics and their impact on the environment, some steps should be taken towards creating healthy cities and  reducing energy consumption.  Keywords: Sustainable development, green building, energy efficiency
