The average windspeed at the San Jose Int'l Airport is 9.5 mph, com-ing from the south/southwest, except in December and January when it comes from the northwest. This is not enough to justify large-scale turbines, but smaller building-mounted products could potentially harness these slower wind speeds, providing power at the household or block scale.

The sun hits its highest point in the sky, 78 degrees above the horizon, at noon on June 21. The lowest noontime point is at 30 degrees on December 21. Between April and August, the sun rises and sets above the E-W line. This means that there are times at the edges of the day when direct light can enter north-facing windows (this is important mostly for the hot late afternoons in the middle of the summer).

Latitude: 37.25 N, Longitude: 121.8 WHeating Degree Days: ~2300, Cooling Degree Days: ~700Moist mid-latitude climate with mild winters. High humidity with short dry summers. Heavy precipitation in winter.

Residential Units: 2,559

Buildings generally form pe-rimeter blocks and respond to the street grid.

Blocks have been kept purposely small to maximize pedestrian/bike permeanbility. The average size of a block is roughly 200’ by 300’(not including mid-block access points such as alleyways and pedestrian pathways).

Due to the demands of solar orientation, many buildings are positioned along east-west streets, creating strong facades. Retail podiums were used to create facades on north-south streets.

Residential Unit Types

Highrise Tower 1090Midrise Apartment 810Lowrise/Townhouse 508Single Family 150 Total 2558

A mix of unit types will encourage a diversity of residents (mixed income, mixed age, mixed ethnicity).

Total Retail: 389,930 ft2

Southern retail will consist of a cinema complex and an anchor tenant supermarket, which is greatly needed in the neighborhood.

A hierarchy of street types is

the public realm. They will prioritize pedestrian and bike movement over vehicle use.

Two special green streets act as connectors through residential districts in the eastern and southern areas of the site. Their serpentine na-

emphasize pedestrian priority.

Back alleys (20’ ROW) func-tion as service corridors for commercial uses and allow parking out of sight.

Neighborhood streets are narrow (~40’ ROW) to discour-

quiet, safe place for children.

Pedestrian and bike routes will be accessible both on-street and off-street. On street lanes and sidewalks will provide routes for com-muters and commercial passerbys. Off-street routes will provide pleasant, slower meandering routes through the development.

Direct pedestrian access will be available to both tran-sit stations. Bridges will be constructed for both transit stations, Caltrain and VTA, allowing bikers and pedestri-ans to pass safely and quick-ly over dangerous arterials.

Mix of onstreet, podium, and underground lots; very little surface parking. Parking is out of sight at the rear in the retail district.

Owing the transit-oriented nature of the project, it is reasonable to provide less parking than a similar development that does not possess such good transit access.
