AMPITHEATER ?

As being one of the most sustainable and green building campus in Indonesia, In this project, I was asked to design an outdoor ampitheater that can attend 135 individuals where i put harmony of nature, manmade, and acoustic to represent the University of Multimedia Nusantara.

The Design of the buildings emphasize on Noise Control, Acoustic Comfort Quality, Thermal Comfort, Natural Ventilation, and of course just like every architectural design, function and visualisation have to meet on their path.

SITE CONTEXT

SITE LOCATION

The Site Location chosen by designer with his reasons, which was the center of activity of whole University of Multimedia Nusantara Area. The Location also already had their pedestrian way where this will be the strong points for the construction site for the ampitheater and the site location is on the park where the concept of the theatre is balance between fusion on Harmony of Nature and Man-Made

NOISE CONTROL DESIGN STRATEGY

Wall to reduce incoming noise sources from back on parking area based on vehicular noise which caused one of the most loudest noise sources.

ACOUSTIC COMFORT

Excellent design and analysis for acoustic comfort involves a variety of strategies and material selection that can ensure that a room or building has an optimal acoustic environment. Here are some strategies and materials that can be used:

Strategy Design:

1. Room Shape and Dimensions:

- Optimize Room Shape: Choose a room shape that can reduce sound reflections and create an even sound distribution.

2. Wall, Floor, and Ceiling Materials:

- Use of Acoustic Absorbing Materials: Use materials such as acoustic panels, perforated fabric, or fiberglass on walls, ceilings, and floors to absorb sound and reduce reflections.

- High Density Material Choices: High density materials, such as brick or concrete, can help dampen sound and prevent sound transfer.

3. Moving Sound Absorber:

- Moveable Acoustic Panels: Install movable acoustic panels or baffles to adjust room acoustics to suit your needs or type of event.

4. Roof and Ceiling Design:

- Use of Perforated or Ragged Ceilings: Complex ceiling designs can help break up sound and avoid harmful reflections.

- Sound Absorbing Material on the Roof: Install sound absorbing material on the roof to reduce sound reflection from above.

5. Acoustic Modeling with Software:

- Acoustic Simulation: Use acoustic simulation software to model and analyze how sound propagates and is reflected in a room. This allows for more precise design.

6. Furniture and Decoration Design:

- Selection of Sound-Absorbing Furniture: Use furniture and decorations that have sound-absorbing properties, such as sofas upholstered in thick fabric or acoustic wall panels.

Acoustic Material:

1.Porous Acoustic Panels:

- Acoustic Foam: Used to absorb sound and reduce reflections on walls and ceilings.

2. High Density Material:

- Perforated Brick or Concrete: Provides good acoustic insulation for walls or partitions.

3. Porous Sound Absorbing Material :

- Fiberglass: Effective in absorbing sound and can be used on walls and ceilings.

4. Ceiling Acoustic Materials:

- Perforated or Serrated Acoustic Ceilings: Increase sound diffusion and reduce reflections.

5. Perforated or Porous Fabric:

- Fabric Panels or Curtains: Capable of absorbing sound and can be used on walls or as room dividers.

6. Innovative Material:

- Passive Technology Based Materials: Materials that can utilize natural movement or environmental changes to control acoustics.

Audio Equipment Settings:

1. Acoustic Monitoring System Usage:

- Sound Sensor Installation: Uses sensor technology to connect and adjust audio settings automatically according to room acoustic conditions.

2. Speakers and Suitable Audio Equipment:

- Placement and Selection of Speakers: Select speakers that suit the characteristics of the room and place them with a strategy for even sound distribution.

By combining thoughtful design strategies with the use of appropriate acoustic materials, you can create a highly comfortable and optimal acoustic environment. It is important to understand the unique needs and characteristics of each space to design the most effective solution.

The Orientation of the auditorium responded to the climate on the site which it blocked the direct coming from the sun on time where the most heat gained.

The Roof blocks the most heat gained. The heat reduced and natural lighting still gained by the circle shaped hole that inspired by the UMN Campus itself.

THERMAL COMFORT

Through the Simulation of heat transfer from natural lighting by the sun, it showed that the design response have been successfully answered the problem for thermal comfort either for the performer or the enjoyers.

As seen as the graphic of thermal showed by the 3d model.

From the data Statistic, it showed the hottest temperature from the site is on 35° on the month of October and lowest temperature on 18° on August

NATURAL VENTILATION

Because the design is under the ground level, designer thinks it will be more maximizing air with lower temperature to stay because the law of physics from different density if air had different temperature.

Greeneries also help the overheating of the air so every performer or audience will have thermal comfort.

The open areas and breathable concept of the building with its circulas shaped hole perforated aluminium panel also help with cross ventilation easily.

Every aspects from natural ventilation is inspired by issue that has been problem around Tangerang excessive heat air.

Through Simulation with AutoDesk Flow Design, the design concept simulated that status of the natural ventilation is already Stabilized Stabilized

Holes on facade remove hot air easily as hot air has lower density than cool air

DESIGN REASONS

FUNCTION AND VISUALS

The roof design is inspired by UMN Building C and D because designer doesn’t want to remove the originality characteristic. The perforated aluminium panel had it’s circular hole pattern was inspired by UMN too but otherwise than aesthetic of visualisation, it’s function is for natural ventilation and natural lighting also diffuse the natural lighting from the sun. Wall is used for backstage need and as reflector as well.

Reflector is placed around the auditorium for the speakers to reach all audience properly using metal reflector and carpet is used on the stage to absorb sound and reduce noise transfer

The Seating (135 individuals) for the audience using nature precast material for its sustainability, easy maintenance, and durability to survive outdoor circumstances.
