Revolutionizing Sustainable Construction in Bangladesh: A Call for Localized Solutions
Explore the need for tailored green building practices in Bangladesh to address climate, cultural, and developmental challenges.
In recent years, Bangladesh has witnessed a surge in interest towards sustainable construction practices, particularly in the garment industry and commercial building sector. Developers are increasingly recognizing the importance of certifications such as Leadership in Energy and Environmental Design (LEED) to showcase their commitment to environmental responsibility.
However, a critical question emerges: Do these international standards truly align with our local climate and priorities?
While LEED certification signifies environmental consciousness and compliance with global sustainability norms, it may not perfectly suit Bangladesh's distinct climate and socio-economic context.

Challenges of Existing Green Building Rating Systems
This raises concerns about how well current green building rating systems cater to our environmental and developmental needs. One significant drawback of relying solely on international certification systems is their lack of customization for local conditions.
Bangladesh experiences a subtropical monsoon climate characterized by high humidity, heavy rainfall, and extreme temperatures. These climatic factors significantly impact building design, material choices, and energy consumption, making standards designed for temperate climates potentially unsuitable here.
Furthermore, Bangladesh's socio-economic landscape presents specific challenges and priorities that any green building rating system must take into account. Issues like resource scarcity, affordability, and access to sustainable technologies are crucial factors for the widespread adoption of green building practices.
Advocating for Locally Relevant Solutions
Recognizing the necessity for a locally relevant green building rating system, stakeholders in Bangladesh are pushing for frameworks grounded in research that consider our climate, culture, and developmental objectives. Such a system would provide guidelines for sustainable building design and construction while fostering innovation and knowledge exchange within our domestic construction industry.
While Bangladesh boasts several architecture departments in universities that mainly focus on design in bachelor's programs, there is a growing recognition of the importance of blending architectural design with scientific principles in education and practice.
Architects excel in creating visually appealing buildings but often lack expertise in energy efficiency and climate analysis, raising concerns about who will address the critical task of developing energy-efficient buildings in Bangladesh.
Urgent Need for Architectural Science Integration
Unlike some foreign architecture education systems that adapt to evolving built environment needs, Bangladesh's emphasis has predominantly been on design principles. To effectively tackle energy crises and sustainability challenges, a paradigm shift is imperative.
One potential solution is the establishment of professional bodies dedicated to evaluating energy efficiency and climate considerations for new constructions and renovations. These bodies would bridge the gap between design and environmental concerns, promoting a holistic approach to building practices.
Globally, there is a growing recognition of the importance of architectural science and technology. Many countries offer specialized bachelor's degrees in architectural science to equip professionals for modern built environment challenges.
Enhancing Building Approval Processes
In Bangladesh, building approval processes primarily focus on physical measurements and structural strength, often overlooking indoor environmental quality (IEQ) and energy efficiency. Despite efforts by regulatory bodies like RAJUK and the inclusion of an energy efficiency chapter in the Bangladesh National Building Code (BNBC), there remains a significant gap in understanding and implementation among building professionals.
The inclusion of an energy efficiency chapter in the BNBC is a positive step, but effective implementation remains a challenge. Increased awareness, education, and enforcement are necessary to ensure compliance with these standards.
Establishing a bachelor's or master's degree program in Architectural Science and Technology, with a focus on energy reduction in the built environment sector, is crucial for Bangladesh. Such a specialized program would equip future architects with the skills to design energy-efficient structures, addressing climate change risks and enhancing resilience.
Building a Sustainable Future
As a signatory to international agreements like the Paris Agreement and the UN Sustainable Development Goals, Bangladesh is committed to reducing its carbon footprint. To access funding for sustainable development projects and comply with international green building standards, investing in education and research in Architectural Science and Technology is paramount.
By training architects in energy-efficient design principles, Bangladesh can decrease its reliance on imported energy and make buildings more affordable to operate. Embracing innovative and sustainable practices is essential for Bangladesh's competitiveness in the global construction arena.
In conclusion, the integration of architectural science into education and practice will drive innovation, creativity, and resilience in Bangladesh's built environment. This shift is crucial for mitigating climate risks, improving energy security, enhancing competitiveness, and meeting local challenges, ultimately fostering a sustainable future for generations to come.
