Bergama National Garden — Double-Move Bioclimatic, Guillotine Glass and Sensor Door

Bergama National Garden Project: A Public-Scale Four-Season Solution

Completed in Bergama, Izmir in 2023, the National Garden project is an important reference work showing where GlobalTente has reached in public-space applications. In the project, double-move bioclimatic pergola, guillotine glass systems and sensor (automatic) door applications were implemented together; it was completed turnkey in approximately 1 month. The result was a prestigious public living area, usable in four seasons and serving many visitors, by combining modern architecture, durability and comfort. Unlike residential applications, public projects require heavy use, high durability and accessibility; this project responded to these requirements by combining three different advanced-technology systems in a single design.

National gardens are public spaces open to everyone in cities, for social and rest purposes; this means high visitor traffic and a need for four-season use. At Bergama National Garden, the aim was to create a social area where visitors are protected from the summer sun, winter rain and wind, while also airy and bright. A public-scale solution had to comfortably host many people, be highly durable and consider accessibility. So the solution was designed not as a single system but as the integration of three complementary systems: a double-move bioclimatic pergola above, guillotine glass systems on the sides and an automatic sensor door at the entrance.

In this project a double-move, not single-move, bioclimatic pergola was preferred. In the double-move model the louvres open in two directions (from the centre to both sides); this makes both drainage and ventilation more balanced in wide, symmetric public areas. Sloping a wide span from the centre to both sides allows balanced drainage of water to a central gutter or to the two edges and gives the ability to control the louvre opening more flexibly over large areas. In a national garden with heavy visitor traffic, the natural ventilation the louvres provide when open prevents a feeling of stuffiness in an enclosed volume; when closed, they provide full protection from rain and sun. This flexibility made the public area usable all day regardless of weather.

Technical Solution and System Integration

The integration of the three systems was the most critical engineering element of the project. While the bioclimatic pergola provided protection from above, the guillotine glass systems could close and open the sides of the area vertically; the sensor door offered a hands-free, hygienic, accessibility-friendly entrance in heavy visitor traffic. Choosing the three systems in harmony in colour, profile and line created an integrated, prestigious look.

Project Details and Process

Guillotine glass systems were chosen for the side enclosure, because guillotine glass is a system where the glass panels open by sliding vertically upward, requiring no side stacking area. This is an efficient solution on the façade of a public area: in good weather the panels are lowered to open the area to fresh air, in bad weather they are raised to close it against wind and rain. The glass surfaces keep the area bright and airy even when closed; this is important for an inviting atmosphere in a public social area. The vertical operation of guillotine glass provided full opening without side-area loss even on narrow or busy façades.

In a public area, the entrance must be accessible to everyone. So an automatic sensor door was preferred. Opening automatically with a motion sensor, the door provides hands-free passage for smooth flow in heavy visitor traffic; it provides barrier-free access for wheelchair, stroller and elderly visitors. The anti-trap safety sensor stops and reopens when it detects an obstacle while closing, guaranteeing safety. Hands-free passage, critical for hygiene and accessibility in public areas, made the sensor door the right choice for this project.

The project started with a detailed survey suited to the scale of the public area: the area was measured, the floor load capacity evaluated and the integration points of the three systems planned. Stronger construction and durable components suited to heavy use were chosen. Installation was run coordinated so the three systems met in harmony with each other; the columns of the bioclimatic pergola, the rails of the guillotine glass and the casing of the sensor door were brought together on the same axis and in the same colour. The turnkey approach provided a single point of contact and single-source responsibility in the public project, completing the process in approximately 1 month.

The biggest challenge in a public project is durability against heavy use and constant access. The systems were chosen in a higher durability class considering that many visitors a day would use them; the sensor-door motor was determined to be of a quality that withstands thousands of open-close cycles a day. The flawless integration of three different systems in a single design required precise planning; the installation sequence and meeting details were laid out in advance so each system works without interfering with the others. Drainage was carefully calculated and tested so there is no pooling over a large area.

When completed, Bergama National Garden became a prestigious public social area, usable in four seasons regardless of weather. In summer the bioclimatic louvres are opened for shade and natural ventilation; on rainy days the louvres and guillotine glass are closed to protect visitors; the sensor door offers an accessible, smooth entrance for everyone. The project showed that a public investment can be both functional and aesthetic, and how advanced-technology systems add value to a public area. Serving many visitors, this application is a strong example of GlobalTente's public-scale project capability.

In public areas a bioclimatic pergola offers much more than a fixed sunshade. In a national garden with heavy visitor traffic, stuffiness and heat build-up in an enclosed volume is a significant comfort problem; when the bioclimatic pergola's louvres open, natural ventilation is provided and this problem disappears. The louvres closing within seconds when rain starts lets visitors be protected without leaving the area. Combined with guillotine glass, the area turns into a fully enclosed, heatable volume that can host events in winter too. This versatility increases the return on the public investment: the area is actively used not just for a few months of the year but for almost all of it. The low maintenance need of the aluminium construction is also an important advantage for the efficient use of public resources.

In public projects, durability is the most critical requirement. The aluminium construction and electrostatic powder coating used at Bergama National Garden provide long life against heavy use and outdoor weather; they do not rust or fade. The sensor door's motor and sensors were chosen of a quality to withstand heavy commercial/public use. Maintenance of the systems consists of periodic cleaning of the bioclimatic louvres and gutter channels, checking the guillotine glass rails and calibrating the sensor-door sensors. GlobalTente provides post-delivery service support in public projects, ensuring the systems work safely for years. This low maintenance burden is an important advantage that lowers operating costs for the public administration.

A national garden must be open to all parts of society; this puts accessibility at the centre of the project. The hands-free operation of the sensor door provides barrier-free passage for wheelchair, stroller and mobility-restricted visitors. The sheltered but airy area created by the bioclimatic pergola and guillotine glass lets visitors of all ages spend time comfortably. The area kept bright by the glass surfaces offers an inviting, safe atmosphere even when closed. In this respect the project is not just a shading but an inclusive social-infrastructure investment that enriches public life. This four-season-usable area added lasting value to Bergama's social life.

The value of Bergama National Garden emerges in the area being usable in four seasons and for different purposes. In summer the bioclimatic louvres open for shade and natural ventilation; visitors spend time in a cool setting even on hot days. In the variable weather of spring and autumn, in sudden rain the louvres and guillotine glass are closed to make the area instantly sheltered. In winter, when the area is fully closed and heated, it turns into an enclosed, bright social space that can host events, exhibitions and meetings. This flexibility maximises the return on a public investment: the area can be programmed year-round regardless of weather and adapted to different social functions. The façade kept bright by the guillotine glass provides an airy atmosphere even at indoor events.

It is important for a public structure to be in harmony with the fabric of its city. In the Bergama National Garden project, the colour and profile line of the three different systems were chosen in harmony with each other and the surroundings, achieving an integrated, plain and modern look. The slim aluminium lines of the bioclimatic pergola combined with the transparent surfaces of the guillotine glass to form a light, inviting architectural language; this strengthened the open, accessible feel sought in a public area. The visual integrity of the systems gave the impression that the area arose from a single design idea rather than added-on parts. This aesthetic consistency made the project not just a functional protection but an urban element contributing to Bergama's public identity.

The Izmir region, which includes Bergama, has a Mediterranean climate with hot, sunny summers and mild but rainy winters. In this climate an open public area suffers comfort problems from excessive sun on summer middays and rain in winter. The system combination chosen at Bergama National Garden responds precisely to this climate: the bioclimatic pergola cuts the summer sun and provides natural ventilation, the guillotine glass keeps the winter rain and wind out. So the public area offers visitors a comfortable setting in all of Izmir's seasons; this is a concrete example of managing an outdoor space with shade in hot climates and with enclosure in cold periods.
