The work entitled The Green Passage, designed by Tobias Kea Suksmalana from Indonesia, won first place in the OGRA 2023 Asia competition.  Expressing his happiness on winning the OGRA 2023 Asia grand prize, Tobias said, "I am very grateful for this achievement; it has been such an incredible experience for me to move forward to higher levels. With this achievement, I will remember to keep pushing myself to improve and continuously learn new things, all in the pursuit of enhancing the quality of life through architecture. These experiences have been instrumental in my growth as a designer and architect allowing me to continuously strive towards becoming better”.


The design about when rethinking passive design, traditional architecture has already practiced the fundamental principles. The orientation, shape, and selection of building materials have been well chosen to adapt to the microclimate in every region of the archipelago. Within the kampong passage, we can still observe and learn about it. Furthermore, the kampong passage also creates a wind tunnel effect. It tells us that along the kampong passage, there are many things that can be rethought in being creative about passive design.


“The potential wind energy from the kampong passage is captured by porous partition such as louver windows and roof walls. This architectural details will reduce the wind speed entering the building. The combination of building mass and architectural details, ensures cross-ventilation inside the house. On the hottest side, the west side, there is a fish pond. It was designed with the intention that cold steam would be brought in by the wind coming from the west-south southwest,” Tobias said.


Prayoga Arya, one of the 1st runner up said that “I felt an overwhelming sense of happiness and pride in winning this award. I joined the Onduline Green Roof Award competition because I wanted to test my abilities and learn from others in the field. Seeing the work of fellow participants has allowed me to broaden my perspective and gain valuable insights. I also want to thank the judges for their valuable feedback and comments. The judging session was truly the highlight for me,” 


“The Onduline Green Roof Award was created as a platform to nurture and recognize exceptional talent in the industry. We are thrilled to honor the winners and showcase their groundbreaking ideas. Through its rich history of over 80 years, Onduline has continuously set new benchmarks in delivering roofing solutions that combine purposeful designs and pioneering technologies. Onduline continues to be trusted by generations for its progressive and dependable products.

The first winner won a cash prize of USD 3,300 and an exclusive trophy, with the runner up walking away with a total of USD 2,300 each and 4th & 5th winners each won cash prize of USD 1,000. The winners were also invited to participate in a design workshop as keynote speakers at the Onduline Indonesia upcoming activity.



The work assessment really takes into account the potential of a roof design that is easy to implement. The roof design of the house must meet the criteria of being healthy, comfortable and applicable, in addition to meeting aesthetic and environmentally friendly values.


"I am truly impressed that this year’s designs demonstrate an in-depth understanding of each space, material, color, lighting, and ventilation conditions. Overall, the entries reflect clear purpose, attractiveness, allure, and high feasibility. And within it, there are technical elements, roof technology, convenience, and aesthetics as core values that we all aim for. OGRA has played a very crucial role in initiating and creating challenges for designers,” said Chairman of Indonesian Green Building Council (GBCI), Iwan Prijanto.


He say that, in the midst of pressure on world food and energy needs, architects and designers must think about the environmental carrying capacity of every product and idea produced. Sensitivity to ecology is an absolute thing that must be considered and implemented in a work. Then that, designing house buildings with a net zero energy concept is a solution for creating energy efficient houses.


“There must be awareness that the earth is a place to live in the present and the future. Being local but thinking globally is the key word for producing products that are down to earth and directly beneficial to the environment," explained.


Principal Architect of Archimetric, Ivan Priatman, say that the largest contributor to emissions reached 39 percent: 11 percent from building materials and 28 percent from building construction. Therefore, it is important to implement an active passive design. Because to present sustainable architectural objects, this strategy is relevant and easy to apply.


Ivan says, so many ideas for creating a passive design and environmentally friendly home. For example, by reducing the use of electrical devices, using energy-saving lamps, using used materials, making openings and gardens in the house, roof designs that support the creation of this microclimate while also reducing noise, and so on. But, of all that, the most crucial thing is energy use. 


“By doing passive design, we don't need to use mechanical or electrical devices to provide comfort as a form of environmental response. That way, energy use can be minimized. The form of response to the environment will be to use more natural resources around us, such as sunlight and wind,"


In the passive design process, Ivan explained several stages that needed to be taken. First, the architect must truly understand the local climate of the design object site. By understanding the microclimate of a place, you can determine the shape and orientation of the building in accordance with the surrounding conditions. Of course, this is followed by concrete steps such as making openings in the building, space organization, shading and the outer envelope of the building, as well as paying attention to the outer space of a building.


Felino 'Jun' Palafox Jr. said that architects must be able to pay attention to every new residential design in the pandemic era while maintaining the mission of preservation and sustainability. If real estate development does not take into account the carrying capacity of the environment, the quality of the city and the lives of its citizens will deteriorate.


“Architecture is very important in creating a better-quality environment. It is the collective task of the entire community to be able to answer the challenges of the city's future now and in the future. "Architectural solutions are needed to make cities more humane, resilient and contributory”.


Country Director Onduline Indonesia, Esther Pane said, Onduline is serious about green building a crucial issue for the future, considering that by 2050, 70 percent of the world's population is projected to live in cities, which is the urban buildings use 40 percent of energy and water globally in addition to consuming a third earth resources.


“Our commitment is to expand our education and impact, not only to building designers in Indonesia but also to the Asian level. we want the echo to be heard more. One of our company group's commitments to sustainability solutions is to ensure that there is socialization and expansion of awareness to a higher scale, through this Asian level competition,” Esther closed.
