Sustainable Well-Being is broadly defined as the exploration of lasting happiness. It highlights the importance of a sustainable lifestyle that is environmentally friendly and socially advantageous. It requires us to pursue well-being in a much more holistic way and within the planetary boundaries.Towards the end of the last millennium, the word ‘sustainability’ was, and still is, the most used phrase with regards to all aspects of our livelihood, and even more so in the built environment field. This was when we understood that progress and environmental conservation are symbiotic – one is supposedly benefiting the other. Wellbeing, on the other hand, carries the notion of happiness, healthy and comfortable. Wellbeing has long been a much researched areas, although mainly in the sociological and psychological domains. Of late, it has increasingly becoming an important agenda in the built environment field as well.Acknowledging the importance of built environment in the pursuit of long lasting happiness, this issue of the Planning Malaysia Journal carries the theme of ‘Sustainable Well-Being in Architecture and Environmental Sciences’. This issue focuses on the design and building of living place which are harmonious and in sync with the environment needs and conservation.The contributions to the study of environmental sciences have come from diverse fields including architecture, town planning, transportation, engineering, legal matters, community development and psychology, and housing. Despite the diversity, each of the fields cannot be viewed as separate entities since they interweave in the broad framework of sustainable well-being. A broader yet explicit understanding of sustainable well-being from diverse research contexts would lead to better decisions, especially in the built environment designs and solutions.Finally, we believe that this issue of Planning Malaysia, can become the platform for experts and researchers to discuss on how sustainable well-being in the built environment can be realized. It is also hoped that the articles in this issue would be useful references for future studies related to the built environment and sustainable well-being.
