SUSTAINABILITY STRATEGIES
SUSTAINABILITY STRATEGIES
OPEN SPACE (LEED)
To create exterior open space that encourages interaction with the environment, social interaction, passive recreation, and physical activities. Area
SUSTAINABILITY STRATEGIES
WATER EFFICIENCY (LEED)
To reduce outdoor water consumption
Reduced irrigation
Harvesting of rainwater
1830810 L/year
Suction tank
A filter placed in the tank clears the water of impurities
Building roof
To reduce indoor water consumption

SUSTAINABILITY STRATEGIES
GREEN TRANSPORTATION (LEED)
To promote bicycling and transportation efficiency and reduce vehicle distance traveled. To improve public health by encouraging utilitarian and recreational physical activity.
Requirements
Provide long-term bicycle storage for at least 30% of all regular building occupants, but no less than one storage space per residential unit.
30% of all regular building occupants: 94 occupants
Number of bicycle storage space to be provided:
To reduce pollution by promoting alternatives to conventionally fueled automobiles.
Requirements
Designate 5% of all parking spaces used by the project as preferred parking for green vehicles.
Install electrical vehicle supply equipment (EVSE) in 2% of all parking spaces used by the project.
Number of parking space to be provided:
Ground
SUSTAINABILITY STRATEGIES
RENEWABLE ENERGY PRODUCTION (LEED)
To reduce the environmental and economic harms associated with fossil fuel energy by increasing self-supply of renewable energy.
