A platform for research: civil engineering, architecture and urbanism
The built environment, which includes buildings, accounts for approximately 40 percent of the totalcarbon dioxide (CO2) emitted as a result of human activity; transport, agriculture and industry combinedaccount for the rest. Reducing energy consumption in buildings thus becomes significant. Heat transferthrough building envelopes, including through roofs, accounts for 60 percent of electricity consumed by airconditioningsystems. The natural insulation afforded by green roofs is one of the most efficient ways to curbroof thermal transfer value (OTTV) and keep such values below 25 Watts/m2, as stipulated under the buildingcode limits in many countries, including Thailand. The benefits of green roofs are several, including storm/flood mitigation in urban areas, reducing urban heat-island effects, increasing urban ecology and wildlifehabitats, increasing usable roof areas as well as aesthetic values. Green roofs have been used to conserve heatin buildings in Scandinavia for centuries and they have gained momentum in European countries, particularlyin Germany and more recently in the United States, in order to combat the effects of global warming.Thailand has had intensive green roofs built over commercial buildings for more than three decades but notdirectly for reducing CO2 emissions. Intensive research is required to find local hardy plants that would bemost suitable and require the least maintenances in a country like Thailand, which is situated in a hot andhumid region. Generally, green roofs are classified according to three degrees of maintenance: intensive,semi-intensive and extensive which requires the least care.Key words: green roof, global warming
