The Study of Energy Efficiency by Central Atrium in Residential Complexes

Atrium with a history of several thousand years, in various forms, in all climates was observed and in the last century with a glass roof and different features, despite the high heat dissipation and interaction of comfort conditions are welcomed in public buildings for reception and living room, providing interior lighting and creating interior green spaces. Limitations of energy resources make necessary optimizing in various ways. By applying the principles of sustainable architecture and modern methods of architecture in addition to the optimized use of sunlight in building, creating a comfortable space for life is possible and energy resources is maintained for future generations. One of the most important ways to use solar energy in the buildings is atriums or middle-forums. Before the atrium is one of the building components, it is the last human achievements and also is the result of his efforts during the history of building for recruiting and better use of sunlight. Atriums due to the physical and environmental factors have a changeable thermal performance that non-consideration of designers to them makes disturbing individual’s comfort and waste of energy. Atriums also have proper capabilities of solar energy gaining and saving that. Energy can reduce 40% of the energy used to provide thermal comfort within the atrium. This paper using library based and descriptiveanalytical study, investigates the effect of optical reflectors of atrium as a important space in today’s architecture and its importance in sustainable and solar architecture and atrium is known as a architectural spaces with a formal, conceptual and functional richness that its existing in a building aside the other spaces leads to pure spatial experiences.
