Once considered a farfetched possibility by skeptics, global warming and climate change are now surfacing as palpable realities of the day. From wildfires in Australia to melting glaciers in Iceland, the year 2020 bid farewell to the hottest ever decade recorded on the planet. Fortunately, though, measures are being taken across all industries to curb our modern world’s carbon footprint, and the case of building and construction sector is no different.
According to a recent UNEP-supported report titled 2019 Global Status Report for Buildings and Construction, construction sector in 2019 continued its notorious position as the largest contributor of greenhouse gas emissions, resulting in 39% of the energy and process-related carbon emissions recorded during the year. The report further states that whilst as many as 136 countries have expressed intentions to work towards sustainable buildings, only a few have elaborated on tangible actions strategized to achieve such plans.
The global building stock is forecasted to grow twofold by 2050 as a direct consequence of increasing urbanization. If left unchecked, GHG emissions resulting from the building industry can rise to 50% of the global carbon emissions in the next three decades. While technological innovations have given way to reduced energy consumption, increasing cooling demand emerging from hot regions have overshadowed a significant positive trajectory. That said, countries across the world are increasingly targeting the urban built environment as a part of their national strategy towards a low-carbon future.
Within the Middle East and North Africa (MENA) region, Qatar houses one of the highest collections of sustainable buildings. Concluding 2019, the country saw completion of more than 50 projects certified under the Global Sustainability Assessment System (GSAS) – MENA’s first performance-based assessment system for green buildings. Based on their overall sustainability credentials, projects registered under GSAS can achieve up to 5 Stars, representing the highest levels of sustainable features in terms of design and build. The award of final rating and certificates follows a comprehensive process whereby auditors from the Gulf Organisation for Research & Development (GORD) analyze several aspects of projects at multiple stages throughout the construction phase.
For the year 2019, here are some green projects successfully completed under GSAS.
During 2019, many recipients of outstanding sustainability ratings were linked with Qatar Rail’s Doha Metro project. With Mesheireb Station achieving the highest rating of 5 Stars, another 17 metro stations and 2 stabling yards at different locations within Doha received 4 Stars for their environmentally friendly design and build aspects. Doha Metro is by far the world’s first metro project with accredited sustainable certification specific to rating railway stations. This has been achieved through GSAS’ unique Railways Scheme that is used for rating the sustainability and ecological impacts of new main station buildings, including spaces that serve various functions of a metro station. According to Consolidated Contractors Company, sustainability of the project has been achieved through responsible site development, water saving, energy efficiency, materials selection, cultural and economic value support and innovation in design. Stations awarded GSAS accreditation during 2019 included those located in Msheireb Downtown, Ras Bu Abboud, Al Sadd, Al Sudan, Bin Mahmoud, Qatar University, Hamad International Airport Terminal 1, Al Doha Al Jadeda, Umm Ghuwailina, Ras Bu Fontas, Economic Zone, Al Wakrah, Al Bidda, Corniche, Hamad Hospital, Al Riffa, The White Palace and Education City.
Lusail City Projects:
A number of projects receiving green certifications during 2019 represented Lusail City – Qatar’s first smart city covering 38 square kilometers, that has mandated GSAS to ensure sustainability of all of its buildings. A flagship project of Qatari Diar, Lusail City has been dubbed as the “largest single sustainable development” ever undertaken in the State of Qatar. Use of native flora and water efficient landscaping mechanisms are some ways the city conserves water. Its integrated transport system reduces GHG emissions resulting from private vehicles. The city’s urban connectivity has been achieved through light rail, ample pedestrian walkways, bicycle tracks and park-and-ride facilities at the public transport stations. With a capacity to reduce up to 65 million tons of CO2 per annum, Lusail’s district cooling plant boasts of being one of the largest in the world. Other green credentials benefiting the entire city include a pneumatic waste collection system, sewage treatment plant and an interconnected natural gas network designed to cut down energy consumption.
Within Lusail, Marina Yacht Club Al Khaliji Tower received the highest sustainability rating of 4 Stars during 2019 followed by another 8 commercial, residential and mixed-use developments receiving 4, 3 and 2 stars. Once complete, the city will have the capacity to accommodate 200,000 residents, 170,000 employees and 80,000 visitors without significant impact on the environment.
Sustainable development is one of the four key pillars of Qatar National Vision 2030, a fact that has provided a natural impetus for public projects to be designed and constructed sustainably. Now, all government projects within Qatar are now mandated to pursue and achieve sustainability under GSAS certification system. To this end, health centers in Al Waab, Al Wajbah, Muaither and Qatar University were successfully completed with 3 Stars sustainability rating during 2019 under the supervision of Public Works Authority ‘Ashghal’. Interestingly, all projects undertaken by Ashghal have been designed and built following sustainability principles – a fact that has been reiterated by Ashghal’s President, Dr. Eng. Saad bin Ahmad Al Muhannadi, who recently emphasized that “Ashghal is implementing GSAS standards in all its public buildings in Qatar, specifically in educational and health buildings.” In the light of these comments, one can safely assume that the upcoming stock of health centers in Qatar will continue to have sustainability at the core of their design and construction.
Hamad Port Project Facilities:
Increasing Doha’s total port capacity, Hamad Port Project started operations in 2016. However, construction has been underway to develop new facilities aimed at enhancing the port’s functional efficiency. The year 2019 witnessed completion of multiple facilities inside the new port with sustainability certification. From accommodation and mosques to civil defense and business center buildings, 19 projects under the umbrella of Hamad Port received sustainability rating between 3 and 2 Stars. Development of the new port has followed comprehensive mechanisms aimed at preserving the environment. For instance, 39,117 mangroves, 14,252 sqm of sea grass and 11,595 hard corals were relocated prior to the construction phase. The relocated flora and fauna are being continuously monitored and have so far proven to be surviving.
Taking green sports infrastructure to another level, Al Janoub Stadium received GSAS 4 Stars during 2019, and rightly so. Soon to be a venue for FIFA 2022 World Cup games, the stadium consumes 30 percent less water in terms of international plumbing codes. More than 15% of its permanent building materials are made from recycled content and more than 85% of the waste generated during construction was processed to be reused or recycled, making it one of the most sustainable stadiums worldwide. Apart from Al Janoub, Qatar University’s Sports and Events Complex was another distinguishing project that received 4 Stars under GSAS Design & Build scheme.
