Implementing the (3ms) Framework to Achieve Sustainable Facade Design and Architectural Resilience in Developing Countries

Rapid urbanization, increasing electricity demand, and developing environmental challenges have created a pressing need for sustainable and climate-responsive architectural solutions in Bangladesh. Despite the growing adoption of sustainable façade techniques, there remains a lack of an integrated design framework that systematically connects sustainability goals with practical architectural implementation in developing-country contexts. This study aims to propose and apply the 3Ms framework—Missions, Milestones, and Methods—as a structured approach for achieving sustainable façade design and enhancing architectural resilience. The study adopts a qualitative design methodology combining an in-depth literature review, architectural case-study analysis, on-site field research, and design development using AutoCAD, SketchUp, ArchiCAD, and Lumion for drafting, modelling, documentation, and visualization. The gathered evidence from literature, case studies, and field observations is synthesized to develop the 3Ms framework, where Missions outline sustainability and resilience targets, Milestones establish progressive design goals, and Methods identify appropriate architectural strategies for implementation. The framework is finally applied to a proposed building design incorporating passive façade interventions, locally available materials, green design techniques, natural ventilation principles, and photovoltaic façade integration. The study presents the architectural application of the proposed framework and evaluates its potential contribution to sustainable façade design through comparative design considerations and photovoltaic integration. The findings highlight the relevance of a structured decision-making framework for guiding architects and planners in developing context-responsive and environmentally conscious building envelopes. However, the study is limited by its design-based and case-study-oriented approach, and further research involving validated building-performance simulation and long-term post-occupancy evaluation is recommended. The major contribution of this research is the development of the 3Ms framework as a practical architectural approach that links sustainability goals with implementable façade design strategies for Bangladesh and other developing countries.
