Portfolio Analysis

Do you know where your savings opportunities are hiding?

Energy savings are hiding throughout your portfolio, so begin your energy analysis with a portfolio wide-perspective. Clearly see which buildings in your portfolio are the highest energy users over time.

Benchmark your buildings to national averages using our automated ENERGY STAR Portfolio Manager integration. Fine-tune your ENERGY STAR scores based operating characteristics.

Building Operation Analysis

Can you spot the energy and demand savings opportunities in your buildings?

Recommissioning is the lowest hanging fruit for energy and demand savings. Over time, buildings tend to lose operational efficiency due to sensor drift, setpoint adjustments, overrides, and changing tenant needs. Typically, an energy efficiency improvement of 5-30% can be achieved with little to no capital cost through recommissioning.

Enpira’s building operation analysis enables you to easily identify recommissioning opportunities in your buildings. Once your buildings are properly commissioned, Enpira becomes your ongoing commissioning service to ensure that your buildings continue to operate at peak performance.

Anomaly Detection

When did your buildings’ energy use anomalies occur?

Anomalies are usage periods where the actual usage significantly exceeds the building’s predicted usage. Anomalies can indicate abnormal operations, system overrides, and excessive peak demand.

By comparing the actual usage to predicted usage, Enpira flags anomaly events in your buildings’ history. Use our Anomaly Detection Reports to identify past anomalies and take action to prevent them from reoccurring.

Disaggregated Energy Usage

Are your buildings using energy as intended?

Not all energy use is the same. Enpira computes weather adjusted whole-building energy use models to break apart energy consumption into its different components. See your energy use disaggregated into separate types and find opportunities to save energy and demand:

  • Base Load: continuous energy use. Identify 24/7 loads that do not need to be on overnight.
  • Variable Load: energy use the tracks with occupancy. Find equipment that can be shifted to off-peak hours.
  • Heating & Cooling Load: energy use that tracks with weather. Identify inefficiencies and degradation in HVAC systems, and eliminate unnecessary simultaneous heating and cooling.

Energy Savings Management

How much energy are your improvements saving?

Whole building energy use models combined with weather normalization unlocks Normalized Annual Consumption (NAC), the average amount of energy a building would use in a “normal” weather year.

Enpira calculates energy savings following improvements by comparing the pre-improvement NAC to the post-improvement NAC. This method is the industry gold standard for energy savings measurement & verification (M&V) and is available for ongoing monitoring and cumulation of energy savings.


Behind the Scenes


Automated Data Collection

Enpira collects utility data the easiest and most automated way available. We can collect data directly from your utility, through Green Button Connect, from your online utility account, or by importing spreadsheets and bills. Enpira automates the utility data collection process to ensure that your utility data is up to date, secure, and error free.

To ensure the security and accuracy of your information, Enpira performs all data collection processes in house. No more manual data entry, data errors, or spreadsheets. Let Enpira do the heavy lifting on your utility data consolidation and management.
