Abstract: Indonesia is located in the tropics with high average temperature at daytime and relative exposure time throughout the year. Solar radiation received by the roof of a building can increase the cooling load. Green roof utilization can be one of the alternative solutions to decrease thermal rate in a building. Extensive green roof is one of green roof types which needs specific construction. Some suitable plants for the tropical zone are Amaranta, Bromelia, Euphorbia and Red Edged Dracaena which need little water. Green roof application with Amaranta and Bromelia in Bandung, using layers which consist of drainage, filter and soil have been able to inhibit heat transfer so the heat is not sentintothe room. Stable roof temperature preserves roof construction strength from the effect of cooling and heating cycle. Constructing a garden using synthetic grass is recommended if drainage is available to ease heat transfer through the roof.
