The ScOLa (School of Languages) Building is a part of a master plan of the Özyeğin University, which is situated in Nisantepe in Istanbul (north-west Turkey). The building is located at the center of the campus, just besides the Student Center. More than 1.450 students, 125 tutors and 10 managers are using ScOLa since September 2014. As the user capacity of the building is very high, there are three entrances to the building. The building consists of 66 classrooms for 20 people, 4 lecture rooms for 56 people, 2 lecture rooms for 90 people, 3 seminar rooms, 25 study rooms, 54 offices, cafeterias, toilets, hallways and various service rooms. All classes are to be used between 08:00 to 17:00 five days a week, accept summer months and all instructor offices are to be used between 08:00 to 18:00 according to schedule of instructors. Since 2015, the basement hosts the students clubs which extends the use of this building to nights and weekends.

The whole campus is designed and constructed aiming to become an example of sustainability and energy efficiency. The University aims to provide hands-on education to its students by providing them facilities that teach by example; energy efficiency is monitored and studied by students very closely; thus, they learn about real performance of an energy efficient building in first person.

All campus buildings are candidates for internationally known LEED (Leadership in Energy & Environmental Design) certification, but this new faculty building aims to go a step further in energy efficient issues. In fact, it behaves 50% more efficiently than the rest of buildings in the campus.

The Turkish Demosite takes part in the “Zero Istanbul 2050″ initiative. This initiative is coordinated by Özyegin University and will increase the visibility of the demosite and facilitate the spread of NEED4B results.

> Demo site team: OZU, BDESIGN and FIBA

Özyeğin University, namely the Center for Energy, Environment and Economy (CEEE), undertakes the research activities and coordinates the demo site activities. B-DESIGN is the architect company in charge of the design of the ScOLa building. FIBA Group deals with project and construction management in Özyeğin University.

In addition, more than 20 stakeholders have participated in the design, construction and operation of this building. From the beginning, the preliminary expectations of the stakeholders are cost affordability, easy maintenance, availability of the selected products in the market and smooth construction facilities.

> Building process and schedule:

During the design phase in 2012 the building design was developed considering the expectations of the stakeholders. 1 M€ saving was achieved on optimization of solar shading. Also, 35 % energy saving was achieved thanks to lightning simulation and optimization, which is entirely fed with PV installation.

The construction works took place mainly along 2013 and the building final commissioning took place in May 2014. The building real time monitoring started in summer 2014 when students started a new academic year.
