Row 1: The urban farm mimics traditional rice terraces of the land. Row 2: The green roof reduces heat gain and produces solar energy. Row 3: Water managing concept diagramsThe integrated design of Thammasat University’s (TU) urban farming green roof is a demonstrative model that incorporates modern landscape architecture with traditional agricultural ingenuity, creating a green roof that supplies organically grown food; public space; clean solar energy; and a closed loop system of water management.Essentially, it seeks to provide an adaptation prototype and an all-in-one solution across Thailand and Southeast Asia to mitigate the effects of climate change and extreme urbanisation such as flooding, food shortage and shrinking farmable, fertile land.CLAIMING BACK RANGSIT’S PADDY FIELDS AND FARMING PRACTICESThe form of the building, developed from the H-shaped floor plan, gave the green roof its mountain form with a massive farming/garden space (7,000 square metres) covering the upper part. Mimicking the traditional rice terraces of the land, the green roof’s cascading farm levels form a detention lawn that slows down run-off and absorbs rainwater—both for up to 20 times more than a normal concrete rooftop—and stores it while using it to grow food.The plants hold the soil together, and any run-off is filtered through each layer of soil and later stored in the four retention ponds that can collect up to 11,718 cubic metres of water for rooftop irrigation and future use. The green roof’s vegetable terraces also filter rainwater through several layers of plants and soil before it leaves the site and reaches residential water sources and marine ecosystems.Adapted from text by Nanticha Ocharoenchai; Kotchakorn VoraakhomProject NameThammasat Green RoofLocationThammasat University, Rangsit Campus, Bangkok, ThailandCompletion Date10 December 2019Green Roof Area22,000 square metresUrban Farming Area7,000 square metresSolar Roof Area3,565 square metresPublic Space Area7,000 square metresService and Utility Area4,435 square metresBuilding Area60,000 square metresClient/OwnerThammasat UniversityLandscape and Green Roof DesignerLANDPROCESS (Kotchakorn Voraakhom)Architecture FirmArsom Slip Institute of the ArtsStructural EngineerDegree System Co., LtdSystem EngineerTPM Consultants Co., LtdContractorCM49Images/PhotosLANDPROCESSTo read the complete article, get your hardcopy at our online shop/newsstands/major bookstores; subscribe to FuturArc or download the FuturArc App to read the issues.Previously Published Showcase No items foundContact us at https://www.futurarc.com/contact-us for older commentaries.
