Architects Call for Indigenous Materials for Sustainable Architecture

Architects and construction experts have called for the development of climate-resilient and environmentally sustainable architecture in Bangladesh by prioritizing local technologies, indigenous building materials and innovative construction practices suited to the country's riverine landscape and climate challenges.

The call came on Thursday at the launch of the Delta Award for Architecture, where organizers also unveiled the award logo, trophy and official application website. The first edition of the award will be held on November 12 to recognize excellence in sustainable, climate-responsive and innovative architectural design.

The event also announced a dedicated engineering and architecture exhibition, while a seminar highlighted the importance of integrated ecosystems, green building finance and science-based urban planning for building environmentally sustainable cities.

Speaking as chief guest, Abu Sayeed M Ahmed, President of the Institute of Architects Bangladesh (IAB), said the award would open a new chapter in architectural research. He urged architects to combine global knowledge with indigenous technologies by promoting innovative use of lime mortar, bamboo and locally sourced timber instead of relying heavily on imported materials.

He noted that buildings are more than physical structures—they preserve culture, memories and history. Referring to growing climate risks, he emphasized developing blue-green infrastructure networks to address flooding and urban resilience while ensuring sustainable construction for future generations.

Jalal Ahmed, Founder of Archi Connect, said the organization is building an integrated architectural ecosystem through Homes, Academy, Store and the documentary series Sthapatya Shilpa. He announced that the Delta Festival of Architecture will be held from November 12 to 14 alongside the 31st Build Bangladesh International Expo 2026.

According to him, the festival—organized jointly by Archi Connect, SEMS-Global and the International Finance Corporation (IFC)—will promote green technologies, energy-efficient buildings and sustainable architecture through awards, regional roadshows, project exhibitions and architectural publications.

Asifur Rahman Bhuiyan, Chief Architect of the Department of Architecture, said the award would encourage architects to pursue innovative and sustainable designs beyond meeting client expectations. He stressed the need to develop high-rise buildings using recycled materials and environmentally responsible construction techniques.

Atif Saeed, Green Building Lead for South Asia under the World Bank Group's EDGE Programme, said scientific planning and sustainable design are essential to prevent environmental and financial losses. He highlighted IFC's work on Bangladesh's Green Building Code, green financing, capacity building and the Building Resilience Index to strengthen climate-resilient infrastructure.

In her closing remarks, Meherun N. Islam, President and Group Managing Director of SEMS-Global USA & Asia Pacific, said collaboration among architects, engineers, developers and policymakers is essential for building smart and sustainable cities. She added that the Delta Award platform will enhance the visibility of climate-resilient projects while accelerating green building finance and sustainable construction practices.

The organizers said the initiative is jointly led by Archi Connect and SEMS-Global, with the International Finance Corporation (IFC) serving as the strategic partner and the 31st Build Bangladesh International Expo 2026 as the host platform.
