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.

In the concept of long term measurement of ScOLa Building energy performance related parameters, detailed real time energy consumption, indoor air quality, HVAC operational details, earth tubes operational parameters and solar plant energy performance are monitored.

The ScOLa building has a “Multi-dimensional Energy Performance Monitoring, Visualization and Optimization Platform”. This platform has been developed by three graduate students with the assistance of the designers, CEEE and automation provider. This has resulted in a start-up company, which is emerging in the automation sector in Turkey nowadays.

All installed energy analyzers and indoor air quality sensors together with process monitoring Hardware, such as calorimeters, are monitored via a central energy management platform called “OzuGreen Energy Dashboard”. The platform intends to guide the building operator for the optimum operation of building systems as a decision support mechanism.

In addition, information is displayed in the “OzUGreen Public Kiosks and LCDs “, which are used by students, visitors and tenants. These dashboards show real time energy flows, enabling, engaging and energizing building occupants to save energy.

Building performance and savings

Energy consumption values are expressed in terms of primary energy. Different conversion factors have been applied according to national or European standards:
