Each tool answers one practical question. Start with the activity closest to your current situation.
Ventilation Planner
Compare indoor temperature with outdoor heat, humidity, wind, PM2.5 and possible smoke before deciding when opening windows may help.
Plan ventilation →Home Heat Profile
Review sunlight, roof exposure, windows, insulation, floor level, night cooling and other pathways that can make a home retain heat.
Check a home heat profile →Indoor–Outdoor Comparator
Record paired readings to see thermal lag, delayed cooling and whether the home is releasing or storing heat.
Compare conditions →Cooling Cost Estimator
Explore how power, operating time, duty cycle and electricity price affect an estimated cooling cost. Assumptions stay visible and editable.
Estimate cooling assumptions →Seven-Day Heat Log
Keep a local record of indoor heat, sleep, ventilation, cooling actions and daily observations to identify repeated patterns.
Start a seven-day log →24-Hour Household Plan
Turn indoor conditions, expected outdoor heat, air quality and available cooling options into a morning-to-night action sequence.

PLAIN-LANGUAGE LEARNING
Understand the conditions behind the numbers
These pages explain common environmental concepts without requiring programming, paid software or specialist equipment.
Heatwaves, hot nights and warming trends
Learn how repeated hot days, weak overnight cooling and long-term temperature changes are described and measured.
PM2.5, smoke and outdoor air
Understand pollutant concentration, AQI categories, smoke context and the uncertainty of model forecasts.
Urban heat and local microclimates
See why shade, building density, surfaces, vegetation, wind and neighborhood form can produce different conditions within one city.
How the information is produced
Review assumptions, limitations, data provenance and the difference between educational decision support and official warnings.
A SIMPLE PATH
From observation to a practical action
- 1Observe
Check the indoor condition and the latest outdoor heat and air-quality information.
- 2Compare
Ask whether outdoor air is cooler, cleaner or more humid than the indoor environment.
- 3Choose
Select a reversible action such as shade, ventilation, a cooler room, a fan or scheduled cooling.
- 4Record
Note what happened so future decisions are based on observations rather than memory alone.
- 5Escalate when needed
Use trusted local alerts and qualified professional support whenever conditions or symptoms are serious.
PUBLIC-INTEREST PRINCIPLES
What this page does—and does not—do
Free access
No purchase button, subscription, affiliate link or product recommendation.
Visible assumptions
Tools show the values and thresholds behind results instead of presenting a hidden score.
Local-first use
Manual entry remains available, and several activities store information only in the user’s browser.
No false authority
Results are educational aids, not official forecasts, medical instructions, emergency warnings or certified reports.
IMPORTANT SAFETY LIMIT
Use official local guidance when risk is high.
Extreme heat and smoke can become urgent, especially for older adults, infants, people with chronic illness, people taking certain medicines, outdoor workers and anyone without effective cooling or clean air. This website cannot evaluate a person’s medical condition or replace local emergency services.
