Architectural design influences both environmental outcomes and occupant behaviors. Green buildings convey environmental responsibility through formal (e.g., signage, tours) and informal means, including natural materials, daylighting, and energy-efficient features. These choices contribute to overall building “atmospherics” that can foster occupant awareness of sustainability. To explore how atmospherics contribute to occupant perception of building sustainability, we surveyed (n = 250) and interviewed (n = 16) occupants of two LEED-certified university buildings—the Green Building and the Green and Biophilic Building—focusing on their awareness of sustainable features and sources of this awareness. The results showed that occupants of the Green and Biophilic Building were significantly more likely to recognize its sustainable features. The diversity and frequency of features identified varied significantly between buildings, with the broader range in the Green and Biophilic Building. Content analysis revealed occupant misconceptions about the sustainability of features like automatic toilets, aesthetic elements, and biophilic patterns, with some assumptions based solely on appearance. These findings highlight how occupants develop green building awareness without formal instruction, underscoring the value of visible design elements in fostering engagement. This study offers practical recommendations for architects and designers to enhance green messaging through non-verbal cues and interpretative educational features.

Background: Home assessment is a critical component of successful home modifications, enabling individuals with functional limitations to age in place comfortably. A high-quality home assessment tool should facilitate a valid and reliable assessment involving health care and housing professionals, while also engaging and empowering consumers and their caregivers who may be dealing with multiple functional limitations. Unlike traditional paper-and-pencil assessments, which require extensive training and expert knowledge and can be alienating to consumers, mobile health (mHealth) apps have the potential to engage all parties involved, empowering and activating consumers to take action. However, little is known about which apps contain all the necessary functionality, quality appraisal, and accessibility. Objective: This study aimed to assess the functionality, overall quality, and accessibility of mHealth home assessment apps. Methods: mHealth apps enabling home assessment for aging in place were identified through a comprehensive search of scholarly articles, the Apple (iOS) and Google Play (Android) stores in the United States, and fnd.io. The search was conducted between November 2022 and January 2023 following a method adapted from PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Reviewers performed a content analysis of the mobile app features to evaluate their functionality, overall quality, and accessibility. The functionality assessment used a home assessment component matrix specifically developed for this study. For overall quality, the Mobile Application Rating Scale (MARS) was used to determine the apps’ effectiveness in engaging and activating consumers and their caregivers. Accessibility was assessed using the Web Content Accessibility Guidelines (WCAG) 2.1 (A and AA levels). These 3 assessments were synthesized and visualized to provide a comprehensive evaluation. Results: A total of 698 apps were initially identified. After further screening, only 6 apps remained. Our review revealed that none of the apps used thoroughly tested assessment tools, offered all the functionality required for reliable home assessment, achieved the “good” quality threshold as measured by the MARS, or met the accessibility criteria when evaluated against WCAG 2.1. However, DIYModify received the highest scores in both the overall quality and accessibility assessments. The MapIt apps also showed significant potential due to their ability to measure the 3D environment and the inclusion of a desktop version that extends the app’s functionality. Conclusions: Our review revealed that there are very few apps available within the United States that possess the necessary functionality, engaging qualities, and accessibility to effectively activate consumers and their caregivers for successful home modification. Future app development should prioritize the integration of reliable and thoroughly tested assessment tools as the foundation of the development process. Furthermore, efforts should be made to enhance the overall quality and accessibility of these apps to better engage and empower consumers to take necessary actions to age in place.

In means of improving the accessibility of performing home assessments, we have developed a novel set of augmented reality (AR) tools. To test the impact of these tools, a user study was run that compares the developed tools against traditional techniques. The findings show that the AR assessment tools generally provide results that are both more accurate and quicker to obtain compared to traditional methods. In addition, participants rated the AR assessment tools as easier to use and were more confident in their assessments compared to when using traditional measures. These results demonstrate that current generation phone-based AR technologies can be utilized as a powerful tool in the assessment process.
