An infographic comparing the two extreme urbanisms of Dubai and the Gaza Strip. While the two urban regions demonstrate surprising similarities when their geographic and demographic data are compared, their political and socio-economic conditions have produced urbanisms that are radically different and equally unsustainable.

In celebrating this year’s World Green Building Week, Carboun has released a visual guide to energy use in buildings with the goal of explaining the overall state of energy use in the region and the significance of buildings as a major sector in energy consumption. It also aims to comparatively explain the nuances of the major trends of energy use in buildings as a baseline analysis for further research. The visual guide, which was researched and designed by Karim Elgendy with additional contributions from a small research team, was based on raw data obtained from the International Energy Agency and the World Bank. Copyrights for all infographics are reserved for Carboun. No reproduction or republishing of any infographic or part thereof is permitted without prior written consent from the author.

During the 1990s and the early 2000s, the UAE, and the city of Dubai in particular, witnessed a rapid rate of growth in its built environment driven by a real estate bubble. In the span of a few years the city’s unprecedented rate of growth, which was driven by both demand and speculation, completely transformed the city. But such growth came at a price. Driven by their need for quick returns, developers cared little beyond delivering a building on time and on schedule. Speed of construction often came at the expense of quality, and issues of performance and energy use played almost no role in the design and construction processes. Common disregard of performance was also fueled by the fact that most buildings were commissioned for developers – rather than owner/occupier clients – since their focus lied solely on reducing initial capital expenditures without considering operating costs that are typically borne by tenants.

These commercial forces, coupled with relatively cheap electricity across the UAE, and a lack of demanding building regulations have paved the way to the development of unsustainable design practices over the last decade. A typical office building in the UAE today is a predominantly glazed high rise tower. Basic design decisions such as orientation, massing, and envelope design are usually made without much regard to their impacts on the buildings’ energy performance, and passive cooling strategies are rarely considered.

In the western context, notions of sustainable development often refer to the need to adjust existing economic models in order to maintain better balances between economic growth and social needs, while protecting local ecologies and reducing the negative impact of growth on the global environment.
In the developing world, however, sustainable development takes on a rather different meaning. With the agendas of developing nations focused on addressing basic developmental challenges such as economic growth, water scarcity, food security, and health, other environmental and social aspects are considered secondary at best and for the most part a luxury that a developing nation cannot afford.
The Environment and the Middle East – Pathways to Sustainability – Volume 1.
In the absence of functioning economic models in the developing world, sustainable development here is not about adjustments to maintain balances. Instead, it is about using this economical tabula rasa to build the foundations of a new economic model in which sustainability and the environment are integral. One of these economical foundations is the built environment.
The built environment of our cities plays a major role in shaping the way we live and work, and given its relatively long lifespan its impact is long lasting. Our buildings determine how much energy we use to maintain thermal comfort while our infrastructures determine how much energy we need for transportation. It is estimated that 40% of carbon emissions worldwide is produced from the occupation of buildings with at least a portion of transportation’s 20% share being a consequence of the way our cities are planned.
Our built environment also influences our impact on the local environment as well as our collective health and wellbeing. Thus, as the cities of the developing world continue to grow, they continue to make decisions about the direction their development takes.
In the Middle East, the role of the built environment is becoming more pronounced as the region continues to experience rapid population increases and urbanization. Increased urban densities together with the rise of consumerism, have not only led to an increase in environmental degradation locally, but they have also meant that the region’s traditionally low energy use — and consequently carbon emissions– are set to rise and to play a larger role in global climate change.
But embracing sustainable development in the Middle East faces many challenges which prevent it from becoming part of the region’s development framework and its building industry practices.

Two weeks ago, The English version of a leading Egyptian daily published an opinion piece on entitled “Our local ‘green’ agenda.” In his article, the author made a number of intriguing arguments that suggest that Egypt has a unique environmental agenda and a set of sustainability priorities that are different from the predominant global ones. He also suggests that imported ‘green’ concepts fail to take into consideration ingrained conservationist behaviors that already exist in Egypt.
While I agree that each country must develop a local approach to sustainability which responds to its specific socio-economic and environmental needs, I found many of the author’s arguments to lack sufficient context, and was therefore concerned that the article could potentially result in an inaccurate representation of the state of sustainability in Egypt.

Throughout the last three decades, the city of Dubai has not been known for its emphasis on sustainability as guiding principles for its development. Not only did it adopt an unnatural rate of growth by middle eastern and global standards, it has also long disregarded the environmental and social consequences of its rapid urbanization. Dubai’s growth relied on -and was economically fueled by- a development model which imported inappropriate and inefficient building forms and planted them in its extreme climate. The result was a 1,500 square miles city (3,885 square kilometers) with isolated island buildings that are not only divorced from their environments, but which also require a great amount of fossil fuel energy to remain habitable.

The city of Dubai also has one of the highest carbon footprints per capita in the world, and even though this footprint is partially a result of energy intensive water desalination processes on which the city relies for its potable water, Dubai’s carbon footprint remains higher than that of other gulf cities including Saudi cities which also rely greatly on desalination.
In many ways, it is fair to argue that the Dubai’s model of development has been, in essence, the antithesis of sustainable development over the last three decades. In other words, Dubai has come to represent the climax of an obsolete development model in which humans attempted to subjugate their environment rather than coexist with it.
In contrast to this un-sustainable development pattern, Dubai’s neighboring city of Abu Dhabi has long adopted a measured and less extravagant development model. Over the same three decades, Abu Dhabi’s development model was generally characterized with a more sustainable pace of development. In the last few years, Abu Dhabi has been attempting to champion sustainable development in the Middle East by establishing a sustainability oriented framework for its development over the next 20 years, and by establishing the Masdar initiative which includes the world’s most progressive sustainable city project at its outskirts with ambitious zero-energy and zero-waste targets.
