The Case Study đ:
110 N Wacker is a towering 54-story high-rise office complex in the bustling heart of downtown Chicago.
This 1.5M+ square foot facility houses mostly office tenant space with a large lobby area consisting of retail spaces. Before engaging in utility-funded monitoring-based commissioning (MBCx), Aero Building Solutions worked as a third-party commissioning agent with the facility and ownership team.
The facility consists of (4) large built-up air-handling units that comprise almost the entire square footage of two building floors. There are also several smaller air-handling units that serve unique spaces of the building, such as the lobby, retail, fitness center, and conference spaces.
Due to the complexity of the mechanical systems and control sequences, as well as the extended build-out process due to the large footprint of the facility coupled with COVID-19, Aero, and the ownership team rolled the project into the MBCx program to assist with seasonal commissioning as well as identify energy savings items.
MBCx services Aero provided have also helped operations and maintenance by running analytics and providing monthly terminal unit checkouts on the entire system, including over 1,500 fan-powered boxes. The live monitoring has also enabled full commissioning of each tenant floor and fan-powered box instead of sampling.
To date, Aero has verified 1,840,513 kWh and 183,016 ton-hrs in energy savings, saving $159,949 in utility costs annually. These energy savings translate into a meaningful environmental impact. We used the US Environmental Protection Agency (EPA)'s Greenhouse Gas Equivalencies Calculator to measure the impact and our savings are equivalent to reducing gasoline consumption by 146,769 gallons annually!
