What Uses Most

The What Uses Most module educates customers about the top three energy uses in their home for the report period. One of the customer's top energy uses is highlighted at the top of the module. Highlighted energy uses must meet one of the following criteria:

It is the customer’s highest energy use.
It is the customer’s second-highest energy use.
The energy use for that category is significantly above the regional average.

The highlighted usage category heading varies depending on the highlighted category and module state (highest energy use, second highest energy use, most above regional average), and is paired with a related energy-savings tip.

Appears in: Limited Income Report, Electric Vehicle Report

Note: While this module was designed for the limited income and electric vehicle customer experiences, it can be used for other audience segments as well. Contact your Delivery Team to discuss module options.

Heading: The heading identifies the energy use state of the highlighted energy category and emphasizes that the top category is an estimate.

Highlighted Usage Category: A set of algorithms identify the customer's highest usage category and the percent of energy used by that category. The highlight appears in a grey box at the top of the module.

Other Usage Categories: An additional two energy use categories and their energy use percentages are listed on the left side of the module. The categories are ordered from highest to lowest. A final "All other energy uses" category presents what percentage of the customer's energy use was made up of any remaining consumption. It is represented by a home icon.

Disaggregation explainer: An explanatory note that clarifies that the categorizations are derived from data science model estimates, and reminds customers that they can improve their report accuracy by completing their Home Energy Analysis is located below the other usage categories. A URL to the Home Energy Analysis where the customer can update their survey is provided.

Paired Tip: An energy-saving tip related to the energy use highlighted in the module is located on the right side of the module. For example, if a customer has indicated in the Home Energy Analysis that they use a heat pump for cooling, an associated heat pump tip and cooling tip are shown. This ensures that the tip information is tailored to the customer's uses in their home. See Paired Tips.

Call to Action: Directs customers to the [Home Energy Analysis where they can provide more details about their home to improve their report accuracy.

User Experience Variations

Highlighted Usage Category

The usage category highlighted in the module heading varies by highlighted category type and module state (highest energy use, second highest energy use, most above regional average). The following table includes an example of the possible heading variations for heating as the highlighted category.

Highlighted category	Module State - Highest energy use	Module State - Second highest energy use	Module State - Most above regional average
Heating	Here's how your home likely uses energy	Heating was one of your highest energy uses this period	Your heating use was likely above the regional average

Electric Vehicle Report

The What Uses Most module for the Electric Vehicle Report includes electric vehicle charging as one of the possible energy uses. If Electric Vehicle Charging is the customer's top energy category, a green leaf icon appears next to the top use category heading with a encouraging “smart, green choice” message below. The message is designed to positively reinforce the customer's decision, and ensure that they feel good about their environmentally friendly choices even when it may take up a significant portion of their energy use.

Heat Pump Usage

If the customer has reported using a heat pump for heating or cooling in the Home Energy Analysis, the module varies in the following ways:

Top Use Category: If a heat pump used for cooling or heating is the customer's top use category, the top usage category appears as "Heat Pump." A green leaf icon appears next to the top use category heading with a encouraging “smart, green choice” message below. The message is designed to positively reinforce the customer's decision, and ensure that they feel good about their environmentally friendly choices even when it may take up a significant portion of their energy use.

Usage category: If a heat pump used for cooling or heating appears in the use category list the usage category for cooling or heating appears as "Heat Pump" in the usage category list along with a heat pump icon.
