Indoor Condition Observation Series
How closely do brief room-comfort observations align with ordinary temperature and relative-humidity readings over seven consecutive days?
Study overview
What the study involves.
This seven-day study compares a simple description of room comfort with readings from a household temperature and humidity display, when available. It looks at consistency over time and is not a health assessment or building inspection.
What you’ll do
- Choose one ordinary indoor room and retain the same observation position for the full series.
- At each interval, record a neutral comfort category, whether a window or exterior door was recently open, and available temperature or relative-humidity readings.
- Complete one short end-of-series check describing schedule consistency and any ordinary interruption to the observation sequence.
Who can take part
- Age 18 or older.
- Regular access to the same ordinary indoor room for seven consecutive days.
- Able to make three observations during a consistent morning, afternoon, and evening window.
- A household temperature and relative-humidity display is useful but not required.
Not part of this study
- No workplace, clinical, secure, or otherwise sensitive location may be used.
- No health symptoms, resident identities, photographs, addresses, or precise location information are requested.
Study steps
How the study works.
Please follow the steps in order. If you miss an observation, leave it blank rather than trying to recreate it later.
Select
Choose one non-sensitive indoor observation point that can remain consistent for seven days.
Observe
Make one morning, afternoon, and evening observation within stable daily windows.
Record
Use fixed response categories and note instrument readings only when a display is available.
Review
Check the seven-day log for missed intervals and ordinary environmental changes.
Information used
What we ask for.
We ask only for the broad categories and observations listed below.
What we ask you to record
- Broad indoor climate description selected from fixed categories.
- Availability and general type of a temperature or relative-humidity display.
- Daily availability windows and confirmation of the seven-day commitment.
- Fixed-category observations of room comfort and recent ventilation.
What we don’t ask for
- Name, email address, telephone number, or date of birth.
- Street address, coordinates, IP-derived location, photographs, or recordings.
- Medical information, symptoms, diagnoses, or information about other occupants.
Sample questions
Examples of what you’ll be asked.
- 01
At this interval, did the room feel cooler than expected, neutral, or warmer than expected?
- 02
Was a window or exterior door open during the preceding 30 minutes?
- 03
Was the observation made within the assigned time window?
Method notes
Why the method is structured this way.
- The same response categories are used throughout the series so that changes in wording do not become changes in the observation scale.
- Instrument readings are treated as contextual observations. Consumer displays are not assumed to be calibrated laboratory instruments.
- A missed interval remains a missed interval; participants are not asked to reconstruct readings from memory.
Limitations
What the results cannot show.
- Room selection, instrument placement, and household equipment vary between participants.
- Self-reported comfort is an ordinal observation and is not interpreted as a medical or indoor-air-quality assessment.
- The series is designed to describe observation consistency and cannot establish the cause of a particular reading.
