The human feeling of satisfaction with a building's temperature and humidity.

Satisfaction with the thermal environment, judged by how people feel.

The rate at which the body produces heat.

How clothing affects the body's heat loss.

The level of physical activity affecting body heat generation.

Building conditions like temperature, humidity and air movement.

Defines conditions for 80% of people to find a thermal environment acceptable.

The human body generates heat to maintain temperature.

The average temperature of surrounding surfaces, considering their size and how much heat they radiate.

The rate of airflow in a space, measured as air speed.

Using wind and temperature differences to naturally circulate air in a building, reducing reliance on mechanical systems.

High humidity reduces how effectively our sweat evaporates, making us feel hotter. Low humidity can make us feel drier.

Different spots within a space can have different temperatures, impacting comfort.

Assuming a stable environment for analyzing comfort, ignoring short-term fluctuations.

Standards for acceptable thermal comfort in buildings, aiming to ensure a comfortable environment for the majority.

Designing buildings to harmonize with the natural environment, using elements like solar radiation and wind for comfort.

A graphical representation showing the average maximum and minimum temperatures and relative humidity for a specific location.

The temperature range generally considered comfortable for most people, typically between 15°C (59°F) and 25°C (77°F).

A visual representation showing how biology, climatology, technology, and architecture all intersect in designing for thermal comfort.

The process of addressing thermal comfort needs of most people in a space by considering factors like temperature, humidity, and air circulation.

Specific temperature values that define the range for thermal comfort for most people in various conditions.

The movement of heat energy from a warmer to a cooler region.

Heat transfer through direct contact between surfaces.

Heat transfer between air and a solid surface.

Heat transfer through electromagnetic waves, with no direct contact.

A material's ability to store heat, proportional to its mass.

A material's resistance to heat flow, opposite of thermal capacity.

The measure of thermal resistance for insulators.

Materials with high thermal resistance, like air and wood.

The amount of moisture in the air. High humidity can make it feel hotter, while low humidity can cause dryness.

High humidity can contribute to mold and bacteria growth, and damage interior finishes.

Low humidity can cause dryness, irritation, and respiratory problems.

The quality of air inside buildings, influenced by factors like pollutants, ventilation, and moisture control.

Materials used in building construction, equipment, and cleaning products can release pollutants into the air.

Ventilation brings in fresh air, removes pollutants, and helps control moisture levels, contributing to good IAQ.

Air with no known harmful contaminants at dangerous levels, where a majority (80% or more) of people are comfortable.

Buildings are tightly sealed, making indoor air quality more critical for human health.

Pollution sources inside, poorly designed ventilation, and unexpected building uses.

Limit indoor pollution at its source, isolate unavoidable sources, provide fresh & filtered air, and maintain a clean environment.

They renovate buildings for new uses, participate in design teams, and specify pollution-free materials.

It leads to improved health and productivity, making it a cost-effective strategy.

This standard defines acceptable IAQ as air with no harmful contaminants at dangerous levels.

These standards focus on ventilation and acceptable indoor air quality, ensuring healthy and comfortable spaces.
