Adrian Smith + Gordon Gill Architecture (AS+GG) released construction photographs of its Expo City in Astana, Kazakhstan, for the Future Energy Expo of 2017. The 174 hectare development includes two planned phases, one for the run of the Expo itself, and the other to follow the Expo's closure in a legacy mode, where pavilions from the former mode will be converted into an office park for the latter. AS+GG won a 2013 competition to design the Expo City, and anticipates delivery of the completed project in advance of the Expo's opening in June 2017.
Project DescriptionFROM THE ARCHITECTS (June 14, 2016)
Astana Expo City 2017, the site of the world’s next international exposition, is now under construction in Astana, Kazakhstan. The Expo’s master plan and 28 buildings were designed by Adrian Smith + Gordon Gill Architecture (AS+GG) around the designated theme, “Future Energy.” The Future Energy concept is aimed at finding ways to achieve qualitative changes in the energy sector, primarily for the development of alternative sources of energy and transportation. AS+GG was selected as the winner of an international competition that featured 105 entries from all over the world in 2013. Once their conceptual design was completed, AS+GG worked under a design-build contract with IT Engineering, a group consisting of Sembol Construction and Mabetex Group.
Located south of Bayterek Tower and east of Nazarbayev University, Astana Expo City 2017 is positioned to become a significant new landmark neighborhood development in Astana. The overall goal is to reduce the energy demand of the site to the greatest extent possible by using both passive and active strategies. The master plan and architecture were primarily determined by site-specific indicators such as solar and wind orientation, weather conditions, and the cultural context. The design team executed a series of studies with the goal of minimizing the site’s energy-use while maximizing its energy-harvesting potential and comfort levels. A significant part of the energy consumed by the Expo community will be provided from renewable sources.
“We worked closely with the client and the governments in Astana and Kazakhstan to develop urban planning and design guidelines that in many instances challenged the established standards, obsolete codes, and regulations,” says AS+GG Partner Adrian D. Smith, FAIA. “Through creativity, patience, and compromise we were able to successfully procure and implement a plan for a sustainable community that will be capable of catalyzing city development in a totally new way.”
Smith says, “A key challenge was to design venues that could be easily converted into usable spaces such as museums, performing arts halls, office buildings, headquarters facilities, and educational facilities, after the three month exposition has transpired.”
"It was important for us to understand the larger issues surrounding all International events like this and to conceive of Astana Expo City 2017 as an integrated urban, architectural, social, cultural, and sustainable contributor to the City; not as an island of buildings but as mixed-use neighborhoods providing quality places to live, work and learn long after the Expo is over,” says AS+GG Partner Gordon Gill, FAIA, adding, “The designs for these amazing projects need to leverage the massive investments that nations make, not just for the event but also for the people, cities, and nations for which they were designed. This was our goal.”
Strategies incorporated into the building design include high-performance glazing that will maximize solar heat gain in winter while providing shading in summer; energy piles that will reduce energy demand and exposed thermal mass that will provide temperature modulation within the buildings during both summer and winter; 100% of rainfall from a 100-year storm event will be managed on site; and 90% of waste generated on-site will be diverted from a landfill.
Gill says, “The forms and language of the buildings were designed to reduce their energy needs and operate as ‘power plants’ that harness energy from the sun and/or wind. The buildings will use the power directly or supply it to the district-wide smart grid for storage or use.”
Astana Expo City’s exposition phase will run from June 10-September 10, 2017, while a secondary, post-exposition legacy phase will convert the site into an office and innovation park with additional residential developments that will attract international companies and entrepreneurs.
“We knew early on that our role as architects and planners would go beyond the delivery of a design,” says AS+GG Partner Robert Forest, FAIA. “What was important to us in this project was working toward a higher standard for urban development and architectural design, one that serves the needs of a 21st-Century community. Our philosophy was to design a community that can be used for the Expo, not an Expo that has to be retrofitted into a community”
When completed, the legacy development will be one of the most sustainably built in the world. The design calls for 100% of the Post-Expo non-potable water demand to be provided by the on-site water reclamation facility and 24% of the Post-Expo electrical demand to be met from on-site BIPV energy systems. As designed, the total Post-Expo grid energy demand is 49% less than an ASHRAE 90.1 2010 Baseline, while the office buildings will use 22%-40% less energy than ASHRAE 90.1:2010 Baseline. Overall grid energy reduction is 59%.
Other key areas that add to the efficient legacy transformation include developing Expo parking areas into residential neighborhoods; integrating exhibition buildings into a first-class office complex; orienting the site for dedicated pedestrian and bike lanes; and creating dozens of public transportation links to the rest of Astana.
