ECO-FRIENDLY ROOF DESIGN FOR URBAN HOMES IN THAILAND

This research aimed to study the eco-roof for home design in urban area in Thailand. The selection area for installing the sample of eco-roof is on a deck of the single-storey residential house in Chatuchak district, Bangkok, having an open courtyard of dimension 4.00 x 4.00 square meters, with stairways leading up to the deck that supports the installation of eco-roof. The eco-roof utilizes an area of 24 square meters; the roof utilizes Photovoltaic (PV) System, using grid connected PV system of 3,600 Watts. The roof consists of 10 solar panels with total generation capacity of 3,100 Watts. Considering the area beneath the PV roof, it is observed that this area can be utilized for growing microgreen. The average crop-time for most microgreen is 10-14 days, depends on the type of seeding used. As the eco-roof extends to cover the deck area, it helps to maintain the temperature within comfort level, and also allows natural air ventilation. The eco-roof can also generate an alternative energy that does not contribute to carbon dioxide emissions into the atmosphere, and is capable of generating about 200 Kilowatt hours per month, which partly helps to reduce electrical cost. For these reasons, the research for eco-roof for urban houses can also be further developed and adapted for roof decks of other buildings as well.
