Biomass Burning over South America
Biomass burning is the burning of living and dead vegetation. It includes the human-initiated burning of vegetation for land clearing and land-use change as well as natural, lightning-induced fires. Scientists estimate that humans are responsible for about 90% of biomass burning with only a small percentage of natural fires contributing to the total amount of vegetation burned. Burning vegetation releases large amounts of particulates (solid carbon combustion particles) and gases, including gree

Through a number of projects and precedent studies, architectural design is studied in relation to the Space Between. The design process is studied in reverse, considering space first and objects second. This is not to imply that objects are not important, but rather that space is equally important.
