Energy Consumption in Thailand
There has been a rapid increase in energy consumption in Thailand during the past three to five years. In 2008, Thailand produced 1.99 quadrillion BTUs (QBTUs) of primary energy, an increase of 0.12 QBTUs over the prior year and a compound growth rate of 4.62% over a 5 year period. Primary energy consumption meanwhile increased by 2.43% over the prior year to 3.96 QBTUs, equating to 57.98 million BTUs per capita which places Thailand into the 49th percentile of countries worldwide for per capita primary energy consumption. Since the numbers of consumption have increased significantly, it is a key measure for energy conservation in Thailand.
Unnecessary energy consumption may lead to environmental problems such as emitting carbon dioxide gas. Carbon emission is the main driving force of global warming, which causes undesirable climate change in many countries. It either causes the climate to be hotter than its regular temperature or colder. This does not only effect human health but also deteriorate the life of buildings and many other products. So it becomes important to be concerned about our energy consumption.
The following pie chart shows the energy consumption of Thailand by sector. The three major use of energy comes from industries (37%), transportation (37%) and residential (16%). In this report, we will focus on reducing the energy consumption in residential sector, because it contributes widely to the total energy consumption and architects can take part in this issue by designing an energy efficient home. Space cooling is important in Thailand most time of the year because of its hot-humid climate, therefore, most of the energy consumed in a household is by air conditioning and ventilation. Air-conditioning system (ACS) is responsible for a significant part of total energy consumption in building. Capacity of ACS is determined according to total cooling load of building.
