The building owner was a long-term customer of the contractor that recently acquired a new multi-tenant commercial office building. The owner approached their contractor upon acquisition, as the incumbent mechanical contractor had recently provided a phased proposal to retrofit a failing automation system. The new contractor suspected that with the help of BuildingAdvice, they could work with the building owner to evaluate the financial benefits of completely implementing a controls upgrade by the late spring of 2018 instead of the phased approach.
In March of 2017, the ABM sales team ran a Scorecard showing the building was using 68.6kBTU of energy per square foot, indicating just below median performance against the national building stock of Commercial buildings. In a competitive leasing market, the new owners wanted to get a deeper understanding of the source of poor performance. To rapidly assess potential sources of waste, ABM deployed BuildingAdvice wireless sensor arrays throughout the building to "shadow" the Building Management System.
These findings led the contractor to run a Project Financial Analysis (PFA) to calculate estimated savings and the cost of delaying upgrades. The contractor found that the building owner could expect $61,000 in energy savings by completing the upgrades immediately, and that the cost of inaction over 15 years would cost them an additional $1.08MM.
New controls and control strategies including:
Using SavingsTracker™, the contractor was able to monitor savings generated from the upgrade. Eight months after the upgrade, the building is on course to generate 140% of estimated annual energy savings. These results, if sustained, could lower the Simple Payback of the project from the originally estimated 5.8 years to 4.3 years. And during this same period the building’s Energy Star Score has increased by almost 20 points since project inception.
