The Challenge: EP Properties, the property management firm that owns and manages the multi-building facitity were so handicapped with the existing control system that they had to literally push an antiquated computer terminal on a cart between buildings to gain access to the system. This presented numerous challenges for effective comfort management response times when equipment went down

The Solution: TraneOregon Energy Services and EP Properties developed a comprehensive approach that included leveraging the local utility incentive program for energy efficiency upgrades plus ongoing contracting services to do the controls upgrades. TraneOregon Energy Services provided all the upfront energy auditing and energy modeling to predict savings for performing these controls upgrades and building tune-up work.  With anticipated yearly energy savings and incentives, the project was sold with an estimated 2 year payback. Actual payback was 4 months! 

Highlights:

  1. Upgrading the backbone DDC system to current day technology with a user-friendly graphical head end interface
  2. Building controls tune-up to improve energy performance for each facility and ease of access/interface building HVAC controls.
