Bilenerji
* Bilenerji was established in 1993 in order to provide the electric energy required by
the production plants owned by group partners located at the settlement area of
Bilkent University and by Bilkent University and besides, The operational steam for
Meteksan Paper Mill and the steam required for heating all the buildings at the
campus of Bilkent University.
* Energy requirements are provided from three units with an established power of 4.5
MW, 24 MW and 8 MW.
* Bilenerji started to generate electricity first in 1995 with a MAN-brand gas turbine of
4.5 MW. Later on, the capacity has been increased to approximately 36.5 MW, by
adding a Rolls-Royce brand gas turbine and Allen Steam brand steam turbine.

08:00 = Library Opening
23:30 = Library Closing
Library Staff: Ali Börekçi
All the maintenance service for library is provided by Bilkent General Directorate
of Construction.
HEATING:
*Central Heating Station: Faculty of Engineering Heat Station (Building Code: A15)
*There is one boiler room in A Block (-2nd Floor) and one boiler room in B Block (-1st Floor, entrance to the room is separated from the existent entrance).
*Both boiler rooms are controlled by Bilkent General Directorate of Construction, only for the A block library staff also can control the boiler room. Boiler rooms
are located in the basement of the library.
*In B block, the temperature of the space changes according to the temperature of the outside.
*For some special collection rooms, radiator temperatures are varied (different) because some collection items require specific temperatures to protect the items.
For example, in Halil İnalcık collection rooms’ temperature keeps in the limited degree of -18 C. Because some books have detail papers and should be protected
from decay.
*Besides central heating, in some spaces of the library have air conditioning for additional heating purposes. In Bilkent University policies, external air
conditioning cannot be used as a heating source because there is a central heating system already. But in some studying areas, periodicals rooms, general
director office, art room and electronic resources have their own air conditioning separated from central heating. Their air conditioner fans are located outside of
the building so the mechanical noise is minimized. For studying areas and periodicals rooms, there is a ceiling type (mounted) air conditioners and for offices and
art room, there is wall type (console) air
conditioners are used only in June, July and August months for cooling purposes. The spaces where student can occupant, heating and cooling systems cannot
controlled by the students. All is controlled by the maintenance staffs.
ELECTRICITY:
*Electricity is provided by the Bilenerji in the Bilkent University campus
area.
*In the library, there are two Uninterruptible Power Supply – UPS rooms
both in A and B blocks. In A block, it is located in the basement floor near
the entrance zone. In B block, it is located in the basement floor as well. An
uninterruptible power supply (UPS) provides nearly instantaneous power
when the main utility power source fails, allowing either time for power to
return or for the user to shut down the system or equipment normally by
closing running computer system applications and using the operating system to shut down the system. In addition, most UPS systems also work to address power
source electrical surges, sag voltage, voltage spikes, frequency instability, noise interference or harmonic distortion from the ideal sinusoidal wave form.
* In case of power interruption, electric energy is given to the electronical devices according to the importance and all lighting is provided during the interruption.
* During the working hours, all library lighting is available but between the 23:00 to 08:00, only outdoor lighting is keep opened by the staff.
Proposed Solution Considering the Sustainability: ICE BEAR
30
Ice Energy, based out of Glendale, Calif., uses an ice-powered air-conditioning unit
called the Ice Bear to cool buildings and in most cases, reduce a building's total
net energy consumption. Ina very abbreviated description, the Ice Bear works by
freezing 450 gallons of water in a tank overnight and making that available for
cooling the next day. When the Ice Bear is switched from its Ice Charging to Ice
Cooling mode, it provides cooling for up to six hours. After its ice has melted, the
job of cooling reverts back to the building's conventional commercial A/C unit,
which is why the Ice Bear works in conjunction with a conventional unit. The
company describes the product as the first effectively loss-less energy solution.

FACULTY OF ART, DESIGN AND ARCHITECTURE
ELECTRICITY:
The FF Building has 7/24 electricity but for both security and efficient use of
electricity, they closed some parts during nigts. Also, the computer labs are
not available all the times. Additionally, the staircases and some parts of the
transitional space in front of restrooms are photocell lighting which means it
works by the movements. Other lightings are manual which also beneficial as
well.
According to the information given by the Halil Sancak, who is responsible
for the electricity in campus, in case of any power outage not all of the electricity is supplied to the building.
Jenerators only help to cover 35-40% electricity (elevators, system rooms, labs and etc.) By the help of UPS
mechanism, the electricity is supplied without any outbreak to the labs and some important rooms.
Water Pipes in FC Building
F Buildings are for the Faculty of Art, Design and Architecture.
We mainly focus on FF Building because it is the center of
heating system for FADA.
All the maintenance service for FF building is provided by Bilkent
General Directorate of Construction.
They do not allow us to take photographs of the heating and
electrical system because of safety issue.
HEATING:
Central Heating Station: Faculty of Art Design and Architecture
There is one boiler FADA building. It is located under the
basement (They do not allow us to see what is behind the
doors). They covered with the partion walls and metal doorway
for the ventitalition.
Boiler is controlled by Bilkent General Directorate of Construction as like in the library. Until last year the
studios and classrooms were very cold because of the façade; however, this summer a façade is renovated
by insulation. All the windows are changed however the locations and materials of the radiators are same.
It also makes a huge difference inside of the building in terms of thermal comfort.
Proposed Solution Considering the Sustainability:
Since the insulation is done during the summer and enought for the heating, there is no proposed solution
except for the radiators. Radiators are placed near the windows mostly and there is no cover on them.
Maybe a cover with air gaps (like in the sketch) might be proposed. (e.g. Radiators in SB Building)
For the electricity, we also think about the spaces. Since there are too many transitional spaces, they need
artificial lights too much. Maybe some sunlight (skylights in entrance part might be bigger than the
existing) might be proposed. Also, the voids in the instructors corridors might be enlarge so that they can
benefit from the sunlight as well.
A huge problem is for the distribution of the water to the other F Buildings. Like in the photograph of FC,
even it is placed on the upper part of basements, it is not architecturally solved. Some suspended Ceiling
might be used with the tiles. Thus, in case of any emergency the tiles can be removed, the problem can
be fixed and the tiles can be put again.
We could not be able to enter the boiler and electrical room, we searched the other building. In V building the boiler room is in the ground floor but the stuff
did not allow us. We found another boiler room under SB (Science Faculty) but we could not be able to enter both electrical room and boiler room. However,
we entered boiler room (illegally) from the transitional space between UNAM and SB Building.

78. DORMITORY
Dormitory 78 is open to anybody in
campus. It has both none-gender
places such as kitchens, study rooms,
model-making rooms, TV Room and a
hair-dresser.
HEATING:
Since it is central heating system, no-one
cannot arranged temperature except the
stuff who deal with heat plants.
Some radiators has arrangement stuff.
According to the numbers, you can decide
on degree but there is no option for that in
Dorm 78.
ELECTRICITY:
The system in dorms are a little bit different fom
the faculty buildigs. Sine it is semi-private space,
it has kitchens, shower areas, study room with
electrical outlets are provided. They have
electricty all day and a jenerator .
For the kitchens, they have washing machines,
microwaves and any other kitchen stuff. Their
oven are used by electric; however, after 10
minutes, the oven is off automatically. (Because
of safety issue and fire concern)
Proposed Solution Considering the Sustainability:
We talked about the students who live in dormitory about both electrical issue and heating. They did not say anything bad
for electrical issue but they feel uncomfortable because of the heat. They said that the interior become to much hot and
they wear mostly very light clothes. Especially for the winter times, when they are sick, the they boil the water in order to
balance the humidty inside their rooms. They also said that the corridors are huge and there is no air in the corridors or
common-usage areas.
The first thing is they can decrease the temperature of the building. Other than that they need cross ventilatons. Maybe
some skylights might be use and in order to make a good ventilation and the floors might be drill in order to reach the upper
floors. Common areas has many subspaces and small windows. Maybe the windows of common areas might be enlarged.
Sketch- Plan
EE Building is the new building for the Electric and Electronical Engineers under the
Marmara Restaurant. It has marble and glass façade and an opening at the middle
of the building.
HEATING:
EE building heating is provided from the heat center of rectorate and library,
however there is also an additional heating center under the building as well;
therefore steam heating is used. As the building is the newest in campus, better
and more efficient insulation and façades play an important role in heating.
EE BUILDING
Low E number glasses were used in window frames to ensure
minimum transfer to the outside from the heat gained by solar
radiation. EE building has individually set radiators unlike other
centrally controlled buildings. Fans for air conditioning units are
on the outside of the building, overlooking the central courtyard.
Outflow is from the façade.
ELECTRICITY:
Electricity for EE building comes from the central system
provided by EnerjiSA and BilEnerji. In times of shortages, power
generators varying from 50 kws to 110 kws provide all campus
with electricity. Also, UPS units are placed to eliminate damage
from short period voltage fluctuations and power deficits. Ee is
one of the few buildings which have %100 power during a
shortage.
