COLLABORATION WITH MECHANICAL ENGINEER | Mehmet OKUTAN

In this lecture, the issue is about collaboration among architects and mechanical engineers. Mehmet Okutan was the speaker of the lecture who is a mechanical engineer and also is working at Okutan Engineering Company in Ankara. The lecture under the topic of “relationship among mechanical systems and architectural design” was informative in terms of mechanical details of buildings and sustainable design.

While architecture was a profession based on engineering, it became the leader of the design team with the emergence of different specialist fields.

The architect leads the design of the building as the leader of the team. For this reason, it should be exclusively used, and the work of other fields of expertise should also be dominant. Even if the architect does not have the knowledge, he must have an idea.

 Building technology explores how the building can improve its performance against a variety of factors like environment, energy, movement, yield..etc. Architectural solutions that were formerly experiential are now being provided by various specialists with technology.

“A house is a machine for living in.  Baths, sun, hot-water, cold-water, warmth at will, conservation of food, hygiene, beauty in the sense of good proportion.  An armchair is a machine for sitting in and so on.” Mr.Okutan is saying that the structure looks like a machine with building construction process, function and life.

INTEGRATED DESIGN aims to produce sustainable architecture, all specialists studied with together.

• Experts predict with simulations and identify the parts that need to be redesigned.
• Allowing the building to fully meet expectations.
• Avoids the extra cost that may arise from incorrect manufacturing.

SUSTAINABLE DESIGN should be based on energy conservation with renewable energy sources such as solar energy, wind power, wave and tidal power, geothermal energy, hydropower in buildings. Efficient usage and design of external and internal loads are important to have sustainable design. Wrong practices in external loads and internal loads cause extra cost and work power.

Performance Expectations

• space heating
• lighting
• space cooling
• water heating

External Loads   orientation, façade, shading…

Internal Loads  lighting, equipment, occupancy, ventilation…

LIFE CYCLE / TIME FRAME

The success of the building; ‘Is about life, place, life, ecological effects and anticipations from the building. The achievement parameters are different in the different measures.

COLLABORATION WITH CIVIL ENGINEER | Zafer Kınacı

In this lecture, the issue is about collaboration among architects and civil engineers. Zafer Kınacı was the speaker of the lecture who is a civil engineer and also is founder of Kınacı Engineering Company in Ankara. He gave some information about the designing static project, structural system of the building and the materials, which is used in wide-span structure. In the end of the lecture Mr. Kınay gave some examples that the structural project is designed by him like Next Level, J.W. Marriott Hotel, Sheraton Hotel, Tim Towers.

Because of the typology of the structure designed by him, the important issue is the largest opening with the minimum columns. While designing a house, the width of a room is maximum 8-10 meters. Most materials are sufficient to overcome this. But if the gym or auditorium or conference room is designed, 30-40 meters opening is difficult to pass without any columns. As a solution of this problem, the prestressed concrete can be used in wide-span spaces which known in Turkish ‘artgerme beton’. When compared with concrete, it can be possible that wide-span spaces can be obtained using thinner sections. When compared the steel, the prestressed concrete can cheaper.

 Technically, after reinforcement is placed, ropes are placed. Concrete is poured and after the concrete is resistance, ropes are stretched. In this stage, this stress reduces the moment of the beam. As the moment of the beam decreases, the deflection decreases and the moment of inertia decreases. So that when the dimensions of the column and the beam are reduced, larger openings can be obtained.

 As an example, in Next Level, 7.5 m centilever was passed with a 40 cm prestressed concrete slap. In J.W. Marriott Hotel, 27 m span and 9m cantilever were passed with prestressed concrete.
