Paradigm Properties recruits Limbach Company LLC to achieve ENERGY STAR® certification.
Project Scope
In 2011, Paradigm Properties hired Limbach Company LLC (Limbach) to benchmark a building located in
Columbus, Ohio, when one tenant insisted that the building must achieve ENERGY STAR certification in
order to execute the renewal of their lease. With assistance from AirAdvice Inc., a provider of an energy
services delivery platform, a focused effort to achieve ENERGY STAR certification was successfully
completed within a few months.
Project Summary
Using AirAdvice's automated link to Portfolio Manager, EPA's ENERGY STAR measurement and tracking
tool, Limbach benchmarked the building and received an initial ENERGY STAR energy performance
score of 76. While this satisfied the requirement for achieving ENERGY STAR certification, there was little
margin for error. Limbach conducted an Energy Savings Assessment using AirAdvice technology in order
to identify low- and no-cost operational changes that could further improve the building's energy
performance. In a one-week period, using portable wireless environmental sensors and Web-based
analysis software, Limbach found several low-cost ways to improve building performance. As Paradigm
Properties began to implement recommendations from the Energy Savings Assessment, Limbach
initiated the process to earn ENERGY STAR certification for the building. By the time the ENERGY STAR
was awarded in 2012, the ENERGY STAR score had already climbed to 80. The building's ENERGY
STAR score has continued to increase and now stands at an 86.
•	Energy Savings
The facility's annual energy usage has improved by 290,000 kilowatt hours, which equates to
annual savings of nearly $25,000, and site energy use intensity (EUI) has improved by more than
16 percent.
•	Investment
This process required very little investment. Limbach performed the initial energy benchmark at
no charge. The Energy Savings Assessment is usually bundled with additional maintenance
services, but if broken out, it would typically carry a fee of $2,000 to $4,000. Paradigm Properties
implemented the recommendations using their in-house staff members.
•	Financial Return
Paradigm Properties saw a return on investment in fewer than two months.
Monitoring & Verifying Energy Savings
EPA's Portfolio Manager is used to track improvements in the building's ENERGY STAR score, along
with reductions in EUI.
Distinguishing Value
Through the use of AirAdvice's technology and Limbach's focus on optimizing the operations and
maintenance of the facility, Paradigm Properties will achieve annual savings of nearly $25,000.
