Chicago architects Adrian Smith + Gordon Gill Architecture (AS+GG) say the 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 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, the architects say in a news release.
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.
“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. “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.”
S“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,” he said in a statement.
“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. “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 percent of rainfall from a 100-year storm event will be managed on site; and 90 percent of waste generated on-site will be diverted from a landfill.
“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,” Gill said. “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 to Sept. 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. “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 architects say the legacy development will be one of the most sustainably built in the world. The design calls for 100 percent of the post-Expo non-potable water demand to be provided by the on-site water reclamation facility and 24 percent of the Post-Expo electrical demand to be met from on-site energy systems. As designed, the total post-Expo grid energy demand is 49 percent less than an ASHRAE 90.1 2010 baseline, while the office buildings will use 22 to 40 percent less energy than ASHRAE 90.1:2010 baseline. Overall grid energy reduction is 59 percent.
