Through natural lighting and environmental analysis, towers are planned within residential cells to permit an abundance of day lighting and to minimize shadow casting from tower to tower. These studies allowed the team to propose building organizations that were not true east/west, or south facing, while maximizing day lighting and ensuring that environmental variables were fully understood. Programmed green rooftops, planned on all “bridge” buildings help contain storm water run-off, while rain gardens provide structured storm water management that connects with the larger constructed and natural bio-swales at the edges of each neighborhood. Solar hot water and photovoltaic systems are integrated into each of the residential tower’s façade design.
