1. A charrette is an intensive workshop that involves all team members, lasts from three to fours hours to a day or more, and aims to create a clear vision for how the project will be developed, including how the green building elements will be incorporated.

2. A pinwheel design groups services such as elevators and stairs in the structure's central core, with short, easily navigable corridors emanating outward in a pinwheel arrangement. In this case, each corridor ends with a floor-to-ceiling window that provides views, daylight, and natural ventilation.

3. The rainscreen approach, by effectively managing moisture, can enhance the durability of exterior wall systems. Rainscreen systems are exterior claddings that incorporate a designed airspace between the sheathing and the exterior cladding to allow water to flow faster to an exit point. The airspace is created by vertical furring strips (boards), a drainage mat, or some other means to hold the cladding off the wall framing/sheathing and create a gap.

4. Title 24 refers to California's Energy Efficiency Standards for Residential and Nonresidential Buildings. These standards were established in 1978 in an effort to reduce energy consumption in California. A periodical process of updating the standards allows for consideration and possibly incorporation of new energy efficiency technologies and methods. It is estimated that California's Title 24 standards, along with standards for energy-efficient appliances, have saved over $56 billion in electricity and natural gas costs since 1978, and will save an additional $23 billion by 2013;

5. Additionally, single-room occupancy projects tend to cost more than other affordable housing projects because they are so densely filled with mechanical, electrical, and plumbing systems. The Plaza Apartments were more intensive because each studio includes a kitchen.

6. The pinwheel design reduced costs for mechanical system and lighting because the shorter corridors, ending in large windows, meant that air and light had shorter distances to travel, thus reducing the length of ductwork and requiring less lighting.
