LENZ software delivers the power of advanced weather normalization routines through an easy to use user interface. Using linear regression models, LENZ determines the best model for each premise and estimates weather normalized annual useage.
How does LENZ work?
- Using the graphical user interface, users select project data files:
- consumer billing records
- daily weather
- normal weather
- Applying various degree days with linear regression modeling, LENZ selects the best weather model for each premise and estimates weather normalized annual usage.
- LENZ delivers powerful graphical analysis in an easy-to-use fashion.
- Easily determine energy usage for a normal weather year.
- Weather-normalized annual usage is critically important for:
- understanding customer usage by class and other segmentation strategies
- evaluation of energy efficiency programs
- customer-specific reporting
- long-term system planning
- Automatic matching of daily weather to periodic billing data at the premise level.
- Unlimited number of premises in analysis.
- Heating and cooling degree day models.
- Automatic selection of best degree day base for each premise in analysis.
- Informative reports and graphics.
- Ships with historical and normal temperature data for all stations in the state of your choice.
- Model diagnostic information for advanced users.
- Export results to Excel or database.
- Built on the powerful analytical and reporting capabilities of SAS® software.
- Available for desktop, server or mainframe installations.
Frequently Asked Questions:
- What are the LENZ models?
The LENZ models relate energy usage for a customer or customer class (i.e. resedential) to user selected weather data. The weather data are not only specific to the utility but can also vary to reflect weather zones within a utility service territory. LENZ allows the user to define the weather station for each customer. This becomes important when significant weather variances exist within the service territory.
