Robert Llewellyn introduces The Sustainable City in Dubai, a quiet, car-free town designed for net-zero energy. The design prioritizes energy reduction, with villas oriented North to maximize shade and reduce air conditioning costs. UV reflective paint and high thermal value windows further minimize heat gain.
The city utilizes gray water from wash basins, showers, and washing machines, treating it on-site for irrigation and cooling biodomes. A farm running the length of the city is irrigated with this treated gray water. The landscape is designed with useful trees like date palms, avocado, and fig, all irrigated with treated sewage effluent.
All car park spaces are shaded with solar panels, contributing to the city's 10 megawatt peak solar installation (40,000 panels). 3 megawatts come directly from parking areas. This solar energy feeds into the grid and powers all services within the city, including cooling pads, the farm, streetlights, and water features.
The city features a community pool with an environmentally friendly treatment system. Recycling stations are spread throughout the city. A mixed-use area at the entrance generates rental revenue, which covers all service and maintenance fees for residents, ensuring economic sustainability.
The Sustainable City has successfully reduced the average carbon footprint of its residents to 3.1 metric tons per person per year, significantly lower than the global average of 7 metric tons. The city encourages electric vehicle adoption by providing charging stations and a cash subsidy of up to 10,000 euros for Villa owners purchasing an EV.
The city has 11 biodomes for growing food, currently experimenting with 40 different herbs and vegetables. These biodomes use a traditional 'fans and pads' desert cooling technology, where fans blow air out, creating negative pressure that draws air through moist pads (wet with treated gray water) and drops the temperature significantly.
The Sustainable City emphasizes being 'Future Ready' by adapting to climate change and reducing environmental footprints. The solar panels are seamlessly integrated into the architecture, making them an aesthetic part of the city rather than an afterthought, showcasing that sustainability can be beautiful and cost-effective when planned from the start.
