Cost of stadiums retractable roof still bone of contention | 2011-12-22. It’s pretty safe to say that barring some type of meteorological miracle, the roof on Lucas Oil Stadium won’t be open for tonight’s Indianapolis Colts game. Most people would understand that decision with rain and cold in the forecast.
But on days like Dec. 18, when the skies were clear and game-time temperatures were in the 40s, the same pesky questions arise about the usefulness of the retractable roof in such a climate and the expense of making the stadium a convertible. It’s difficult for architects and engineers who worked on the stadium to pinpoint the exact cost of adding a retractable roof as opposed to a stationary one. Or maybe they just don’t want to. But it’s true that some of the same materials and engineering would be used whether it was retractable or not. One thing is certain. The cost isn’t insignificant. All and all, though, there’s still a solid argument for the roof. Edificios sustentables. Built in the arid suburbs of Jaipur, Rajasthan, The Pearl Academy of Fashion combines modern exterior styling with ancient Rajasthani architecture -- designed to keep temperatures down without artificial cooling systems.
The entire building is raised above the ground and a pool of water -- integrated into a recreation and exhibition space -- keeps temperatures low through evaporative cooling. As architect Manit Rastogi says, "When water evaporates in heat, it immediately brings down the temperature of the space around it. " This method was employed over 1,500 years ago by local Rajasthanis, who built "baoli" or stepwells -- bodies of water surrounded by a descending set of steps, helping to create a microclimate in the surrounding structure. The building is protected from the environment by a double skin which is derived from a traditional building element called the "jaali" which is prevalent in Rajasthani architecture.
