` Focus We have seen that temperatures and rainfall are on the rise. Coupled with the imminent global issues of global warming and climate change, it is important to invest in alternative cooling methods without causing more damage to our only home. This is especially relevant in Singapore where we experience summer all year round and people choose to counter this weather via air-conditioning. However, it is important that we must not neglect the experience of the user while tackling this issue. We believe that the two are not mutually exclusive and we can achieve both at the same time.

` Precedence Methods to maintain the room at a comfortable temperature Houses gain/lose heat through: 1.Air infiltration 2.Heat conduction 3.Solar radiation According to one government study, winter heating bills may be reduced by as much as 15 % while summer cooling energy needs may be cut by as much as 50%.
