The project concerns the design of the building of the Police Division in Kastoria, which includes office spaces, temporary detention rooms, staff dormitories, multipurpose room, shooting gallery and auxiliary spaces.
The total area of the building is 3100 sq.m and consists of a basement, ground floor and three floors.
The study was based on the existing approved preliminary design, with the necessary changes made in collaboration with the relevant departments.

A full bioclimatic design was implemented in the project, taking into consideration the specific uses. Certain strategies were applied in order to ensure conditions of thermal and visual comfort, reduce the total energy consumption and improve the overall quality within the building.

The design of the building, takes into account the climate, the orientation, integrates natural phenomena, reduces heat losses and controls solar gains from the shell at all times, thus achieving conditions of thermal and visual comfort.
A conventional construction (concrete bearing structure-brick walls of substantial thickness) was selected , which permits the development of large thermal mass and hence thermal inertia with small temperature variations , while the thermal insulation of all building elements (building components and glazing) are characterized by optimal factors.

Regarding heating/cooling energy, the design objective is: for the heating period, the efficient collection, storage and transmission of solar gain, while reducing heat losses. By maximizing the openings with south orientation and integrating local architectural tradition in the design of mobile external shading devices - consisting of horizontal and vertical elements - the building openings function as passive solar direct gain systems with controlled penetration of solar radiation. For the cooling period the design provides additional control of heat gains, incorporating shading devices, in combination with applications that exploit natural phenomena (chimney- effect by using solar chimneys), in order to achieve adequate cooling and ventilation all year around. Further more the construction of solar chimneys even includes sunlight reflection devices, which permit natural light penetration deeply inside the building, thus improving the conditions of visual comfort.
All elements of bioclimatic design were successfully integrated in the morphology and typology of the significant architectural heritage of the region. The proposed materials are degradable and of low energy consumption (production, transportation), and the design supports "clean" building technologies.
