CLIMATIC ZONES OF INDIA

Regions having similar characteristic features of a climate are grouped under one climate zone. Predominantly, Indian subcontinent is divided into five climate zones-1. HOT AND DRY.2. WARM AND HUMID.3. COMPOSITE4. TEMPEARTE 5. COLD

CHARACTERISTICS OF WARM AND HUMID CLIMATE•Warm and Humid climate is characterized by high relative humidity(around 70-90 %)

•Precipitation levels (about 1200 mm per year.)

•The temperatures usually vary between 25–35 ºC in summers; while in winters, temperatures vary between 20–30 ºC. 

WARM HUMID CLIMATE

The building design in this climate should aim at –

•Reducing heat gain by providing shading

•Promoting heat loss by maximizing cross ventilation.

• Dissipation of humidity to reduce discomfort.

WHAT KIND OF BUILDING DESIGN IS REQUIRED?

PASSIVE DESSICANT COOLING SYSTEM

WHAT IS PASSIVE DESSICANT COOLING SYSTEM? It is a method that removes moisture from the air which decreases the relative humidity. The moisture is removed by passing the air through a material called a desiccant. As the desiccant absorbs the moisture from the air, it becomes saturated and loses its ability to continue absorbing moisture. At this point, the desiccant is then regenerated, or dried, with solar heat which evaporates the moisture into the outside air. It is then ready to absorb more moisture from the air entering your home.

Double roof. The outer roof will gain more of heat and there would be a dissipation of heat from the space between the 2 roofs.
