Science lab buildings arc mechani­ cally interesting. For instance, chem­ istry fume hoods must vent to the outdoors. "and they require very high huurly turnover," says Marlin. "Yuu need to bring the laboratory exhaust up Lo the ruof and have it blown by high-velocity 'induction' fans [Martin calls these 'jet cngi nes') way up into the atmosphere to meet environmental requirements for dispersing lab gases." Traditional laboratory exhaust sys­ tems allow heat to be lost. To elimi­ nate the need to reheat supply air, MaRS Phase 2 was designed as a "shell and core" hu ilding with hase building systems to a llow tor zone level cool­ ing and heating.
