8. RESIDENTIAL BUILDINGS
The three different zones:
1. Bathroom
2. Bedroom
3. Other room

9. TEMPERATURE VARIATIONS
A residential building is a dynamic system; the outdoor
environment, the internal heat gains and the ventilation rates
are just some of the constantly changing parameters
influencing the indoor temperature.

11. IMPROVING THERMAL COMFORT IN
RESIDENTIAL BUILDINGS
 Proper Orientation of Building
 Proper Ventilation
 Using Shading Devices
 Proper Lighting
 Creation of Microclimate
 Preventing Infiltration
 Use of Light Color Paints
 Proper use of Electric Appliances
 Sensitizing Building Professionals

13. MEASUREMENT OF INDOOR CLIMATE
The instruments were used to measure physical comfort
variables; liquid Crystal thermometers, wet and dry bulb
hygrometer, and digital thermo-anemometer were used for
collecting data of the indoor thermal environment.

14. CONCLUSION
 Better comfort in building
 Energy saving
Material conservancy
