Start with the household glance.
Selected pollen is Low, modeled AQI is 42 (Good), and the illustrative cooling window is already active. The approximately 45¢ benefit is based on entered assumptions—not measured savings.
Try two fixed sample conditions: a favorable evening and a high-ragweed day. Follow how the recommendation changes.
Four host-rendered design examples show distinct states, from health-first advice to unavailable data.




Earlier labelled screen samples follow a constructed evening, a high-ragweed variation, and a separate unavailable-data state. Select any image to view it at full size.

Selected pollen is Low, modeled AQI is 42 (Good), and the illustrative cooling window is already active. The approximately 45¢ benefit is based on entered assumptions—not measured savings.
Health names the selected pollen outlook and the modeled air-quality reading. Only three of four selected pollen types are covered; the missing type is not silently treated as Low. Pollen is a daily forecast, not an hourly decline.
After health and weather checks, Energy recommends an open-window period ending at 11:10 PM. Why This Plan shows the factors and owner-entered rate behind the illustrative 45¢ estimate.
The Week view covers seven days, but selected pollen extends only five. Mosquito activity is a weather-based likelihood, not a detector at the property or a prediction of bites or disease.
Saturday Air & Window compares a sample optional AQI with a modeled value. The Sunday Dry-out card is a separate outdoor-forecast example.
The clear 74°F weather, modeled AQI 42, and household rate stay the same. In Example B, selected ragweed is High, so the Home view says Keep Windows Closed. Health makes that daily pollen condition and shorter-outdoor-period guidance visible.
Energy withholds the open-window plan and savings estimate after the pollen check fails. The separate health alert makes the reason visible; “I saw this” acknowledges the message.
This final frame is a different sample fixture—not what happened next in A or B. When current outdoor evidence cannot be verified, the screen offers no positive cooling advice.
Switch between favorable and high-ragweed sample conditions, then explore the reasoning. Related design screens appear beside matching views.
