There are three building types in Cappadocia that have

constituted by carving massive rocks according to
necessity of space. These buildings are also a type of
earth-sheltered buildings. According to Xu-dong,
traditional cave dwellings have become an important
developing direction in architecture because of its
energy-saving characteristics [2].
y Rock-cut & masonry buildings: These buildings are
named as rock-cut & masonry because some of their
parts consist of carved rocky earth and other parts are
masonry. Cave dwelling parts are generally in the first
floor and other parts are above the carved parts. These
buildings have the characteristics of both types.
y Masonry buildings: These types of buildings have
structures which are made of stone (special to this
region) and bound together with mortar. All types have
a special traditional construction process. They are
shown in Fig. 3.
B. Material Solutions
Traditional materials are used in the construction of
vernacular architecture because they are harmonious with
environment and their transportation is easy. Using
traditional materials is energy saving, too.
Geological characteristics of the region have great effects
on the regions’ architecture. The study area, Bahceli Village,
is located in the Cappadocia Volcanic Province (CVP) (Fig.
4). As seen in Fig. 4, the village is in the volcaniclastic and
cinder cone field (in Urgup Formation). Total thickness of Fig. 2. Scenery and plan of Bahceli Village [11].

IV. CONCLUSION
Providing an integration of today’s technology and
vernacular houses which are compatible with nature, have
comfort requirements like heat and sound insulation and
minimize the use of energy in regions like Cappadocia, which
has cold climate in winters, hot and dry in summers, is very
important for today’s sustainable architecture. According to
Esin et al., traditional design and construction process have
constituted worthwhile examples of architecture by gathering
local resources and workforces [15].
In the scope of this study, a village which has the general
vernacular architectural features of Cappadocia Region,

features about material types, natural ventilation, chimney
design and lightning were explained. The outcomes of this
research obtained from vernacular architecture are given
below:
y Analyzing building types and features of the place
where the building will be constructed is essential for
constructing an ecological building in this place,
y Using local materials for the constructions without
affecting the nature adversely is very important for

y Design principles of natural ventilation system and
chimney style should be decided according to the
principle of ‘‘Remove the dirty air from the place
quickly’’. Some local equipment can be useful and has
the potential of being used in a design as if it is a part of
the construction. Therefore, all immediate environment
of the building area should be analyzed in detail to see
the opportunities
