Thermostat Settings & Mecho Shades
Tenants should not tamper with or attempt to adjust temperature control thermostats (or obstruct air flow from vents) in the leased premises. The Building Engineers of Columbia Square shall adjust thermostats as required to maintain the building's standard temperature. Management requests that all window Mecho shades remain down to help maintain comfortable room temperatures and conserve energy.
