What are the best biomimicry solutions to apply to architecture design to solve problems in tropical areas such as heat, mosquitoes, and energy consumption?

Passive cooling systems have proven to be very efficient and reliable. (See The Eastgate Centre in Harare, Zimbabwe and The Portcullis House in London, UK) This system mimics the self-cooling mounds of African termites. Check this page for details about termites' process and how it was adapted for The Eastgate Centre: http://inhabitat.com/building-modelled-on-termites-eastgate-centre-in-zimbabwe/ But basically, this is how it goes (by Wikipedia): - Start of day: the building is cool. - During day: machines and people generate heat, and the sun shines. Heat is absorbed by the fabric of the building, which has a high heat capacity , so that the temperature inside increases but not greatly. - Evening: temperatures outside drop. The warm internal air is vented through chimneys, assisted by fans but also rising naturally because it is less dense, and drawing in denser cool air at the bottom of the building. - Night: this process continues, cold air flowing through cavities in the floor slabs until the building's fabric has reached the ideal temperature to start the next day Passively cooled, Eastgate uses only 10% of the energy needed by a similar conventionally cooled building.
