Air & window plan
Compare outdoor conditions and identify possible natural-cooling windows, with health checks considered before a recommendation.
Portfolio project / Home Advisor
A clearer moment to open the windows.
Home Advisor is a pre-release home guidance project designed to bring weather, outdoor air, pollen, and energy context into one explained decision—so a promising cooling window does not hide a health reason to keep it closed.
The problem it addresses
Useful guidance, not another wall of numbers.
“It feels nice outside” is not the whole decision. Outdoor air can be cool while pollen is high; a short ventilation opportunity can change as a forecast ages. Home Advisor brings the relevant conditions together and shows why it suggests an action.
The appliance offers guidance rather than operating windows or HVAC. The website demo uses fixed sample conditions.
What the intended experience brings together
01 / Timing
02 / Health context
03 / Explanation
04 / Planning
A decision with context.
Pollen and outdoor air
See daily pollen in relation to selected sensitivities, modeled air quality, and explicit unavailable states instead of treating missing data as “low.”
Energy “why”
Understand the assumptions behind a potential savings estimate. It is a calculation based on owner-entered settings—not a measured reduction in utility use.
Beyond right now
Browse a seven-day weather-oriented planner, weather-based mosquito likelihood, and a dry-out view based on outdoor air. Data horizons vary by source.
Earlier design examples
The health check changes the answer.
Earlier host-rendered examples compare the same sample evening with Low and High ragweed; the window advice changes with the health context.

The design challenge behind the screen.
See how the interface weighs comfort, health, and the quality of the available information.
Turn separate forecasts into a decision.
A household needs to weigh comfort, weather, outdoor air, and selected pollen before opening windows. A number-only dashboard can hide the caution that actually changes the answer.
Useful without pretending to measure everything.
Settings and decision logic run locally, while fresh forecasts still need public providers. Pollen is daily, the default AQI is modeled, and the device does not sense indoor air, window position, or HVAC activity.
Action first, reasons close behind.
The interface checks health and weather limits before estimating a cooling benefit, names the time window, reveals source freshness, and withholds positive advice when evidence is insufficient.
Release gate still open.
Home Advisor is an owner-tested pre-release touchscreen prototype. Weather appeared on the installed development build after its scheduled refresh, but full settings storage still blocks durable alert-history rewrites. Offline travel and reconnection remain to be verified on the physical device; no customer release is available.

A representative decision
What changes the answer?
01Start with opportunity
Outdoor air may be cooler than inside, creating a possible natural-cooling period.
02Check the constraints
Pollen sensitivity, air quality, forecast freshness, and current weather can change that opportunity.
03Show the reason
The recommendation explains whether to open, wait, or keep windows closed—and what information it used.
Custom work
Have a different decision to make clearer?
Home Advisor shows how ZeroHour Systems approaches applied software, interfaces, and real-world constraints. If your team has a decision-support or interactive-system challenge, we can talk through the work it would take to build it.
