Study Notes

Internal Environment of Buildings

Buildings provide a space for occupants to work, relax, or rest.
Indoor environments should be pleasant and comfortable.
Indoor climate includes air quality, thermal conditions, acoustic conditions, and lighting conditions.
Outdoor environment affects buildings with natural ventilation.
Proper design & use of materials ensure comfortable indoor environments.
Good indoor environments improve occupant health, comfort, and satisfaction.

Necessity of Pleasant Indoor Environments

Occupants spend most of their time indoors.
Indoor climate is crucial for well-being, productivity, and health.
Indoor air quality, temperature, humidity, sound levels, and lighting levels all impact the indoor environment.

UN SDG 3: Good Health and Well-being

Goal 3 focuses on healthy lives and well-being for all.
People spend a significant portion of their time indoors.
Indoor environments greatly affect people's health and well-being.
Proper indoor air quality, lighting, temperature, and noise control can positively impact physical and mental well-being.
Poor indoor air quality can cause respiratory issues, allergies, or cardiovascular diseases.

Factors Affecting Indoor Climate

Ventilation: Involves providing fresh air and removing stale air, which is vital for maintaining good indoor air quality.
Thermal Conditions: Human bodies need to lose heat to the environment to maintain a constant temperature; the surrounding air's temperature influences this heat exchange.
Acoustic Conditions: High sound levels can negatively impact occupants.
Lighting Conditions: Natural and artificial lighting affect occupant well-being.

Instruments Used to Determine Factors

Air Movement: Measured using hot wire anemometers or rotating vane anemometers.
Air Temperature: Measured with digital thermometers.
Mean Radiant Temperature (MRT): Measured using globe thermometers that show the average effect of radiation from surrounding surfaces.
Relative Humidity (RH): Measured with whirling hygrometers.
Sound Level: Measured using sound level meters.
Lighting Level: Measured using lux meters.
