Case studies
What Do Our Clients Think?
“We installed PEAK+ to ensure our HVAC units remained on-line during hot summer days. This was an investment for our tenants to ensure all day, reliable comfort.”
— Kim CarT, LBA Realty
“PEAK+ lowered one of our data center’s annual operating cost by $80,000; it quickly paid for itself.”
— Phillip Shatter: Verizon
“We selected PEAK+ to help achieve our sustainability goals. PEAK+ drastically cut our energy consumption by 40,000 kilowatt hours, and thus, our carbon footprint.”
—Mark D’Ambrosi, Summit Properties
Trane Commercial Services
Atlanta, Georgia
This case study is the result of a joint effort between Georgia Trane and PEAK+. The results were analyzed and prepared by Trane’s in-house LEED AP, Energy Engineer.
Project Scope
The objective of this study quantified the energy savings potential of the PEAK+ System in the humid Atlanta climate. This project did not evaluate the additional benefits of the PEAK+ System, including reduced maintenance costs, increased cooling capacity, extension of HVAC equipment life or improved HVAC equipment reliability.
PEAK+ SOLUTION
Trane installed the PEAK+ System on a 40-Ton Trane DX Package Unit on the Georgia Trane main office building in Atlanta, Georgia. Unit performance was monitored using an Amprobe DM-II PRO electrical data logger/recorder, from August-September.
Beale Air Force Base
Yuba County, California
Project Scope
Standard air-cooled chillers become less efficient and less effective when they are needed most: when it’s hot outside. This facility’s refrigeration chiller was a prime target to help reduce electricity costs and ensure chiller reliability.
PEAK+ SOLUTION Results:
After a season of use, Beale AFB commissioned a study by the Western Cooling Efficiency Center on the performance of the PEAK+ system. PEAK+ reduced annual chiller electricity use by 22% while dropping the peak demand for this unit by 20% on hot summer days. Water consumption of the PEAK+ system was negligible; accounting for only 2% of the annual dollar savings per year. The system achieved Beale AFB’s electricity reduction goal.
Private Data Center
Southern California, USA
Project Scope
The owner of a large data center facility with 3,310 Tons of air-cooled HVAC equipment had trouble losing compressors during peak temperature conditions. Additionally, their aging equipment was near the end of its useful life and the customer wanted to defer the large CAPEX expenditure required to replace all of their HVAC. The customer selected PEAK+ to ensure HVAC system reliability and to allow it to operate for additional years before a total HVAC system replacement.
PEAK+ SOLUTION Results
Thanks to lower condenser air inlet temperatures, this customer went from losing upwards of nine compressors a year to losing zero compressors since installing PEAK+, resulting in fewer maintenance calls and a much lower maintenance cost. Additionally, they experienced a 25% overall decrease in HVAC energy consumption bringing their PUE from 1.60 to 1.45 during the summer months. The resulting six figure annual cost savings went straight to the data center’s bottom line.
Riata Trace Commercial Complex
Austin, Texas
Project Scope
The owner of this eight-building commercial office property (688,100 SF) looked for ways to save money and help meet their sustainability goals. Electricity demand charges, or kilowatts (kW), accounted for 80% of this customer’s utility bill so reducing HVAC demand, which sets the demand charges for these buildings in the summer, was critical.
PEAK+ SOLUTION Results:
PEAK+ projected a total demand reduction of 978 kWs using our system, saving the customer over $100,000 in demand charges alone. We then secured a $300,000 rebate for our technology with local electric utility, Austin Energy. This covered half of the cost of the project for the owner. After one season of use, the customer reported a savings of 959 kWs; 98% of what was forecasted. Additionally, other savings resulted from reduced energy consumption (kWh) and reduced annual coil cleanings.
Summit Properties
Aliso Viejo, California
Project Scope
The owner of this five-building office complex had aging HVAC equipment that would trip off-line on hot days. Additionally, it did not supply enough cooling capacity which led to tenant discomfort. The owner was at risk of losing tenants.
PEAK+ SOLUTION Results:
By choosing the PEAK+ system instead of purchasing new HVAC equipment, the owner was able to defer large capital expenditures and solve their problem at a much lower price. Since installing the system, the customer experienced zero unit tripping events and zero compressor failures. In addition, tenant complaints about a warm office space were eliminated. PEAK+ used its Energy as a Service model to install, operate and maintain this customer’s PEAK+ system year over year so that the customer only needed to enjoy their energy savings while increasing the cooling comfort for their tenants.
Royal Ridge III: JLL
Irving, Texas
Project Scope
Royal Ridge III utilizes six chillers on a rooftop with a parapet wall. These walls restricted air flow to the chillers and caused them to trip offline in the heat. Being frequently driven to maximum head pressure was, in turn, burning up compressors.
PEAK+ SOLUTION Results:
By installing the PEAK+ system on all six chillers, the temperature of the air cooling the coils was reduced enough to keep the chillers from tripping offline. The building has not lost any compressors since installing PEAK+. Additionally their tenant, American Airlines, realized a 10% overall savings on their power bill.
