Regional Site Analysis: Phoenix, AZ
This is part of an ongoing series where we will publish site performance studies in specific geographic regions. In this analysis we focus on two years of data collected from live, operating Peak+ site(s) in Phoenix, AZ. The dataset analyzed is:
- Region: Phoenix, Arizona
- Units: 2
- Months of Data: 16
- Raw Data Points Analyzed: 400,000+
What follows below are visualizations of our system performance derived from this dataset. Data collected represents time periods when Peak+ equipment was in operation.
Phoenix’s hot and dry climate is one of the best to realize the full benefits of our technology. In 2022, Phoenix had 113 days where the temperatures exceeded 100°F (145 days in 2020). As the graph below demonstrates, when installed, Peak+ technology turns these 100°F days into sub-80°F days for your HVAC unit.
The chart above shows the relative temperatures by hour of day when Peak+ was in operation. The x-axis is the time and the y-axis is the temperature. As you can see, the outdoor temperature rises over the course of the day [Blue], but with Peak+ installed your HVAC air inlet temperature [Orange] stays consistently low.
HVAC systems typically account for around 30-60% of a commercial building's total energy usage. In places with hot climates like Phoenix it is common for cooling to account for 50% or more of a building's total energy consumption during the hottest months of the year. Reducing the air-inlet temperature experienced by your HVAC will substantially reduce the electricity required to cool your facility and confer material reductions in your building’s electric bill.
In the chart below, the black line represents the outside air temperature, the blue dots represent the temperature behind the pad.
You may notice that at lower temperatures there are some datapoints where Peak+ is not as effective at reducing the temperature. This happens for two primary reasons: (1) The system has just started up, so the datapoint was collected before Peak+ hit peak effectiveness (in which case it is short-lived). (2) The wet bulb depression is compressed, typically there is a higher wet bulb temperature in the morning.
Another way to view the temperature drop is to look at the average temperature drop at different Dry Bulb temperature Bins.
On a normal 125°F day in Phoenix your HVAC unit would be forced to operate well beyond its factory design point thus straining to keep your building cool without tripping offline. That same HVAC unit with Peak+ installed will experience an 85°F day, operating normally with increased efficiency and plenty of capacity to spare.
What this means for you
The above is real-world data from a Peak+ installation collected over 2 years of operation. The customer’s aggregate annual energy savings far exceeded the required upfront investment for Peak+ as well as increased HVAC reliability and decreased HVAC unit wear and tear. We have seen similar performance at other sites in the Phoenix area plan to share those stories in future updates.
