Description / Additional Information

Describe the key innovation and technology aspects of the project

Project Narrative

The Tower features numerous sustainable attributes such as an operable double-skin facade, an onsite grey water reuse system, locally sourced building materials, fixtures and furniture made from recycled materials, and numerous other green strategies to substantially reduce the environmental impact of the building. Some of these features enable the Tower's heating and cooling systems to operate in a "net-zero-energy state" up to 30% of the year. This is accomplished by its innovative solar chimney.
