Solutions

Energy Conservation Measures (ECMs)

The RCx project identified three key ECMs:

  1. AHU scheduling optimization
  2. Enhanced economizer function via integrated make-up air unit
  3. Domestic water pump optimization

The building hired their preferred controls contractor to implement ECMs 1 and 3, and to complete enhancements to their building automation system (BAS).

Impact

By implementing the selected RCx ECMs, the owners of 1111 E.Touhy successfully reduced the building's energy consumption and operational costs. The rapid payback period further highlights the effectiveness of RCx Flex projects in improving energy efficiency and occupant comfort while minimizing costs.

When I work on these projects, I put in a lot of hours and do what would I do if I owned the building. If I did, I’d leave no stone unturned looking for ways to save money. Plus, it makes the building more comfortable and it’s good for the environment, so why not? I have fun doing this and I think these are all reasons why my projects are successful.
