It's not just sunlight. A building that widens as it goes up will also focus wind. The effects are a bit more 'wave' than 'particle' - no beams, just constructive interference - but the principle is the same. This reminds me so much of University of Illinois at Chicago. Most of the humanities are housed in this gigantic concrete monolith that widens as it went up, supposedly to represent the 'city of broad shoulders'. But ironically, it better captured the 'windy city' -- we'd fight yard-long patches of gale-force wind that would appear out of nowhere and steal your papers. "The architecture ate my homework" was a not unheard-of excuse -- and one that as a TA I actually honored on one occasion.
