Thermal and Illuminance Performance of a Translucent Green Wall

AbstractThe aim of this research is to evaluate the energy savings and environmental benefits contributed by vegetal facades in comparison with traditional ones. To this end, a particular type of vegetal facade (translucent green wall) has been designed, built, and monitored in an experimental building. All the constructive components of the system are recyclable and reusable. A similar facade without the vegetal layer has also been installed in the same building to compare both models. These two experimental facades are monitored by duplicate probes that record temperature, humidity, and illuminance data. A weather station installed in the same experimental building collects data about solar radiation and outside humidity. Using thermal and humidity data, the internal vegetal layer helps to prevent an excess of temperature inside the building, thus contributing comfort during the summertime. This prototype entails spatial innovation and is relatively easy to apply to housing construction, but further res...
