The 411 East Wisconsin Center’s mechanical systems provide heating, ventilating, and air conditioning to all tenant areas. Building temperatures are maintained between the hours of 8:00 a.m. and 6:00 p.m. on Monday through Friday and 8:00 a.m. to 1:00 p.m. on Saturdays, except holidays. HVAC outside of these hours is available for a fee. After hours HVAC requests or questions regarding temperature levels should be directed to the Building Management office at (414) 347-0411.

It is against building policy for a tenant to bring in a space heater in order to manipulate temperatures. Due to the potential fire hazard, 411 security officers will remove space heaters found in tenant spaces.
