Green mindfulness seems to play an important role in promoting sustainability in architecture, but discrete areas of knowledge are still widely unknown. This study aimed to explore the publications that exist on the nexus between green mindfulness and architecture, and to find the architectural features that tend to foster green mindfulness. The study conducted a systematic literature review by searching publications from databases including Scopus, Google Scholar, and Thai Journals Online in September 2022. Five authors—one architectural researcher, two architectural professors, and two architects—independently reviewed the full-length articles to confirm their accuracy and objectivity. Eight articles were selected for examination by descriptive analysis showing the publication year, source, and citations of the articles. Thematic analysis was used to find the characteristics of the architectural atmosphere with the potential for fostering green mindfulness. Finally, only one study was found that was truly concerned with architecture and green mindfulness. This publication showed that mass and volume are associated with biophilic design, fascination with biophilic design, and affiliation with biophilic design. Material and object refer to natural material; light is in reference to natural light; and landscape and viewpoint suggest plants, greenery, and natural views, while details regarding color and sound were not explored.
