APPENDIX B (continued)
b) If only a RUSSWO summary is available, use the two hottest
months of the year as determined in STEP 3. From Part C, "Surface Winds",
determine the total percent calm for these months, as follows.
(1) Add the percentage of time within the natural ventilation
boundary (STEP 2) and the percent above the boundary (STEP 3) for each of the
two months to determine the total time above the comfort zone boundary.
(2) Multiply the percent time calm by the total time above the
comfort zone boundary for the month and divide by 100.
If result is greater than 10 percent for either month, then fans
must be installed.
Proceed with schematic site and building design, using the
appropriate concepts and design strategies as discussed in Sections 2, 3,
