Aflivadem Vocational School at Ankara, Turkey (Mediterranean Climatic Area)
This educational district at the AFLIVA DEM vocational school campus is composed of several buildings and includes different use profiles, which presents significant potential for synergies between different buildings and for the implementation of performance improvement strategies at a district level. The site is an educational complex including buildings for housing students (female and male dormitory buildings), the educational and teaching buildings and the staff housing building. Some additional facilities devoted to providing auxiliary services such as the canteen and some sports facilities complete the district.
The demonstration building is a boys’ dormitory located in the vocational school in Ankara. The dormitory block ranges between two to four storeys in height. The bedrooms and bathrooms occupy the upper floor while the offices and main entrance occupy the ground floor.
The main structure consists of reinforced concrete construction with external render finish with poor insulating qualities. The hipped roof has limited mineral wool insulation along the ceiling joists. The ground floor is of standard concrete construction again with minimal insulation. All the windows are standard double glazed with aluminium frames and no external shading devices.
All the buildings of the complex are connected to a district heating network. This HVac network consists of three natural gas boilers for space heating provision with a nominal power per unit of 930 kW and an additional gas boiler for the production of DHW with a nominal power of 581 kW. Ventilation is generally provided by natural ventilation, apart from the mandatory extract ventilation required for the canteen and sanitary facilities.
