A Visual Guide to Energy Use in Buildings in the Middle East

Karim Elgendy

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.

A Visual Guide to Energy and Emissions in the Middle East

Following on Carboun’s recent article discussing the two trends of energy and carbon emissions in the Arab World. Carboun has recently released a visual guide to energy and emissions with the goal of explaining the fundamentals of energy use in the region and how it relates to carbon emissions, economic development, climate change, and renewable energy. The guide, which was researched and designed by Karim Elgendy, was based on raw data provided by the World Bank and the World Resources Institute. It aims to explain the regional trends in local details but within the global context. Copyrights for all infographics are reserved for Carboun.

Two Trends of Energy and Carbon Emissions in the Arab World

Karim Elgendy

Discussions on the environment in the Arab World have traditionally been limited to the negative impact of region’s fossil fuel exports on climate change. In recents years, a more regional discourse has emerged that also addressed the region’s water scarcity, rapid urbanization, environmental degradation, and the expected impact of global climate change and sea level rise on its most vulnerable regions.

However, such discussions often overlooked the region’s own energy and ecological footprints and the impact of its own energy use on climate change. In the past , such disregard may have been justified by the fact that the region had not yet experienced the kind of economic development and prevalent consumerism that was common in most of the developed world. Such justification was supported by the region’s historically low rate of energy use and carbon emissions. In fact, the Arab world which constitutes 5% of the world’s population, emits just under 5% of global carbon emissions according to World Bank data, and except for Saudi Arabia, no single Arab country is responsible for more than 1% of global emissions. The energy use of an average Arab person is still below the world average and less than half that of an average european.

In February 2010, the design for Al-Birr Foundation Headquarters in Riyadh, Saudi Arabia, has been named as the winner of the 2010 Architectural Review / MIPIM Future Projects Awards under the ‘tall buildings’ category (Image 1). The unbuilt project, designed by Perkins+Will’s New York Office, was commissioned for Al-Birr Foundation, a non-profit organization aimed at alleviating poverty and caring for disadvantaged families and children.

The Design

Of the many features of the design of the 59, 000 sqm tower, perhaps the most interesting is how it was concieved as a sustainable urban tower that responds to the environmental characteristics and the microclimate of the city of Riyadh, which is a challenging climate to address given the extreme solar exposure and the heat conditions of Riyadh.

Faced with these climatic conditions and a deep plot of 1000 x 1200m, the projects’s designers response was to rethink the high rise typology in this context. The design’s most visible response to the climate is the building’s envelope which was designed as a large rectangular frame of brise-soleil enclosing the occupied parts of the building. This shading frame  was designed to respond to both the different amounts of solar radiation received by each elevation as well as the interior spaces behind it. To achieve this  result, a mapped shading mesh was devised to provide varying levels of openness for different locations of the different elevations depending on its solar exposure and its spatial/contextual influences. The result was an envelope that resembles a mesh of varying densities surrounding the building and simultaneously protecting and revealing the activities behind it.

This proposed design solution thus helps the building reduce its solar heat gain while maintaining its views towards the city (FIgure 1). In addition to this shading effect, the mesh-like dynamic treatment of the envelope has also helped animate the building’s expression with the dense and sparse zones of the facade adding a dynamic effect to what otherwise may have become a static pure form.
