Much of the environmental control is achieved through passive means, before resorting to less efficient, active systems such as air conditioning. Fresh air filters through a desiccant, then to conventional chillers. As the desiccant extracts moisture, it also cools the air inside. But to keep the desiccant functioning, energy is needed to remove the accumulated moisture. This is where sustainable technologies come in: An on-site biomass boiler—fueled entirely with green waste from the city’s national parks—and hot air collected from the top of the glasshouses provide sufficient energy to cool the conservatories.
“The result is not an experimental building, but its ventilation strategy has an experimental component,” Finch said. “In a globalized environment, there is so much interest in how we deal with density and this combination of urbanism with a garden that is both an attraction and nature is a wonderful solution. If they can cool these glasshouses through natural cooling, we should ask why it can’t be done in other buildings?”
