Abstract

The energy consumption of the construction sector and its overall environmental impact has greater potential for improvement than those of many other sectors. Most energy consumed throughout the lifecycle of a building is expended during its operation and maintenance, for which the building envelope plays an important role. This study reports on the design, construction, and thermal performance evaluation of a ventilated façade. The façade should be quickly assembled, disassembled, and stored in containers for easy onward transport. Such features comply with the Rules and Building Code of the Solar Decathlon Middle East 2018 and the relevant Eurocodes. The façade is constructed using bio-based materials in keeping with the principles of a circular economy. The exterior cladding consists of sanitary paper, grass, reeds, recycled textiles, drinking water treatment waste, bio-based polyester resin, and other materials. Temperature and the air velocity measurements recorded on the façade in Dubai showed that the façade had contributed to cool temperatures within the apartment, particularly during the hottest hours of the day. The façade is a promising option for climates with hot summers and mild winters as it contributes to reducing energy consumption and the environmental impact of building materials.
