Bioclimatic architecture involves designing the built environment taking into account local climate features in order to achieve thermal and visual comfort, utilizing solar energy and other environmental sources as well as the natural climate features. Passive Solar systems integrated into buildings to exploit environmental resources for heating, cooling and lighting are basics of bioclimatic design. Bioclimatic architecture has become in recent decades, the basic decisive factor for the construction of buildings worldwide, and in most countries is now a key design criterion for small and large buildings that designers, architects and engineers take into account. This is due to lower energy requirements for heating, cooling and lighting of buildings that arise from designing with bioclimatic architecture principles and multiple benefits that this produces:

• Save energy by significantly reducing losses due to improved protection of the shell and thermal behavior of building materials and components.

• Thermal energy (heat) through direct or indirect gain solar systems that contribute to the thermal needs and partially covers the building’s heating requirements.

• Creating conditions of thermal comfort by reducing demands with thermostat setting (lower temperatures in winter and higher in summer)

• Maintaining indoor air temperature at high levels in winter (and correspondingly low in summer), thus reducing the load needed to meet the energy requirements of alternative systems that are used in the building.

In light of the above, bioclimatic design must have:

• Simplicity of use of applications and avoiding complicated passive systems and techniques.

• Small involvement of the building user in managing the operating systems.

• The use of widely applied systems.

• The use of techno-economic energy-efficient technologies.
