Sorry this was a typo, the first two lines should be:

ac            5.8s      6.0s     24.7s     23.0s    +    4.0s
aermod      223.9s    227.3s    485.8s    467.6s    +  233.1s

All the sources are on

 http://www.lps.ens.fr/~dominiq/polyhedron/

under name.f90. There are also some variants with hand optimization:
ac.v1, air.v1, chan.v1, indu.v2, indu.v3, indu.vm, test_fpu_v1,
for those interested. Except for the indu.v*, the optimization has
been minimal.

Cheers
