13、sing calculations based on the annual nonhome-based commuting trips per employee), only regular building occupants can be included in the occupant commute survey. Those who are absent on 1 or more days of the survey period because they telecommute or work a compressed workweek must be listed as maki

14、ng zero trips for the day (or using zero vehicles, per the SCQAMD metric). Employees who walk, cycle, tele-commute, use public transit, or use a fuel-efficient vehicle (as defined in this credit) are counted as making zero conventional commute trips or using zero vehicles. Those who carpool or ride-

15、share for more than 50% of their commuting trip distance are counted according to the number of other commuters in the vehicle. For example, if 2 people carpool to work together for most of the distance to the building, each is counted as making half a trip; 3 carpoolers are counted as making 33.3%

16、of a trip each. Employees who report vacation or sick leave days should be noted but not included in the results. Example 4 Building D has 100 regular occupants, 25 of whom use alternative transportation for their daily commute. To determine the AVR for the building, divide total occupancy (100) by

17、the number of conventional single-occupancy vehicles used for occupants daily commute (75). In this instance the ARV is 1.3. To calculate the RCCT, divide the number of trips avoided or reduced by the use of alternative transportation (50) by the total commuting trips (200). The RCCT is 25%. For res

18、idential projects (i.e. those using calculations based on the annual home-based commuting trips per capita), residents commute patterns only should be included in the occupant commute survey. For residential calculations, assign a value of zero to a trip in which a resident carpools. Example 5 Apart

19、ment building E provided a survey to its 10 occupants. After a preferred parking and transit voucher program was started, seven residents commute to work only using a single occupancy vehicle in both directions, 1 resident carpools to work but drives alone on the return trip, another resident carpoo

20、ls to work but takes transit home and a final resident takes transit in both directions. This building is considered to have reduced its number of regular commuting trips by 25% since 5 of the 20 commute trips used alternative transportation.
