Purchase, installation, and maintenance of an air conditioning system for a building in Zimbawe has immediate and long-term costs. The challenge was to create a self-regulating ventilation system that would keep the building at temperatures that are comfortable for workers and residents.
Mick Pearce worked with the construction company Arup to design the structure, which is
passively cooled and does not require a fuel-based air conditioning
system. The $35 million building saved 10% on costs up-front by not purchasing an air conditioning system. Rents are less expensive in this building compared to nearby buildings because of the savings in energy costs.
