It is a fact that technology has the ability to do wonders in the field of industry, medicine, agriculture and communication. However, it cannot be denied that it is also one of the culprits to what is happening to our environment such as the occurrence of climate change, deterioration of natural resources and alarming waste problems. These situations gave the researchers the idea to create an improvised eco- friendly device that could contribute to lessen problems on energy crisis, ozone layer depletion and waste problems.
A. BACKGROUND OF THE STUDY Global warming is an overall state of existence that is the cumulative effect of hundreds of environmental factors. It is a gradual increase in the earth's average surface temperature and one of its effects is the extreme heat during summer that could lead to heat stroke. Heat stroke is the most severe form of heat illness and is a life-threatening emergency. According to Manny Mendoza, weather forecaster at the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the hottest days are usually experienced in the country in May. (Helen Flores, 2012). Philippines has a high relative humidity because of high temperature and the surrounding water bodies. The average monthly relative humidity of Philippines varies between 71 percent in March and 85 percent in September. The warm temperature and high relative and absolute humidity together give rise to high
