New Headquarters

IMEG provided LEED Fundamental Commissioning services for the CDOT Region 1 Headquarters which was awarded LEED Gold certification. Commissioning services were provided for both
the 175,000-sf office building and the 130,000-sf parking garage. The main commissioning activities included an onsite kickoff meeting, construction site observations, controls submittal review, pre-testing checklists, TAB review, and functional testing. The building’s main HVAC system consisted of a heating water plant and 2 roof top air handing units, which served common ductwork throughout the building. There were 118 VAV boxes and 106 fan powered boxes that provided temperature control to the individual spaces. Supplemental heating and cooling in electrical rooms and vestibules was provided by a combination of unit heaters and split system air conditioning units. One large domestic water heater and a hot water recirculation pump supplied the building with domestic hot water. Lighting and daylighting controls; including occupancy sensors, automated timeclocks and photocells, provided a majority of the lighting controls.
