This paper discusses the design and installation of an extensive west facing living wall on the University of Texas at Austin campus. The pilot project illustrates the importance of bringing multiple expertise together to address challenges in urban design. In its hot and subtropical climate, this custom, prefabricated system holds 99 hexagonal cells that are alive with diverse regional plant species, and varied wildlife habitats. The design of the honeycomb system allows for an appropriate level of installation and fabrication efficiency, alongside its aesthetic provision. Every cell in the wall holds flora and fauna specificity with a geometric logic for self-shading the substrate volume. The appropriateness of the vegetation indicates that there are suites of native plant species, tolerant of higher temperatures and limited water availability, especially critical in the specific climate of this application. The project ultimately manifests a new approach to architectural design with a living wall system to integrate fauna with flora and utilizes nature’s intelligent honeycomb patterning throughout its fabricated domain.

This study focused on the evaluation of a modular green roof system designed for residential roofs to determine its thermal performance. The green roof system was installed on roof models with three slope angles: 1˚, 20˚ (5/12 pitch), and 40˚ (10/12 pitch). Differences in the average temperature of the undersides of the roof decks were compared between green roof models and shingle roof models at the three slope angles. Experimental data were collected for three summer months to compare the cooling load difference of both roof types at all slope angles. A case study was conducted on a residential single-story unit in St. Louis, Missouri. Results showed that a residential green roof system can yield significant energy savings in the summer season. Roof slope angle is also an important factor in heat gain of building envelopes due to its relationship with the sun’s incident angle that affects the solar irradiation on the building.
