Again, the Eden Project Biomes by Exploration Architecture has delivered a design that incorporates an enclosed membrane made of ETFE. This is a high performance polymer, assembled in triple layer 'pillows'. These pillows are 1% the weight of glass (a factor 100 saving in embodied energy and allows more sunlight into the building. This means that the structure is self-heating and its humidity level is less than the weight of the air.
From this, I am leaning towards having an enclosed agricultural space so that crops are not subjected to varying temperatures and humidity;- causing loss to water vapor and reducing quality and yield.
