Insulation for cooling
On a sunny day in a hot climate country, a roof temperature of 70ºC is not unusual. Without insulation the extreme heat can penetrate the building and transform it into a sweatbox where people find it uncomfortable and difficult to work or live.
In most cases, air conditioners are used extensively to cool down the indoor temperature of buildings – and the associated energy costs also grow. In countries with poor insulation standards, investment in air conditioning becomes an expensive ‘solution’ that puts a strain on personal finances and the countries’ electricity supply.
With the use of insulation to stop the heat from entering into the building through the roof or it's facade, you can keep the cool air inside and at the same time reduce energy used to run air conditioning by almost 70%.
Some of the South European countries with their subtropical climates are facing similiar problem and increased demand for air conditioning. An example on the effective use of insulation can be found in Southern Spain, where weather is similar to the one in Asia with high humidity and temperature. Terraced houses in Spain were thoroughly insulated with stone wool insulation. As the result their cooling bills were reduced by about 85%!
Air conditioning will increase
According to McKinsey/Vattenhall Climate Map, usage of air conditioners in the world’s largest economies such as the US, China and India will triple before 2030. In order to control and reduce the use of air conditioning in these countries, it is crucial to insulate better. This is especially important in fast developing countries of India and China and other Asian regions where there are many new buildings being built .
