The graphshowing childrens under ten havemetabolic rate higher than any otherage, which is about 55W/sqm.PRODUCED BY AN AUTODESK EDUCATIONAL PRODUCTwind towerwind towerwind towerfountainfountainfountainSOLAR RADIATION / AIR TEMPERATURESHADING BY THE ROOF &ARABIAN CANVAMost of the main space are covered by the roof itself. Only part ofthe service space like the main corridor is not covered by the roofbut by traditional canva. Light is encouraged to enter the space bythe openings like window and skylight in the hall. Another pointto note is the roof is also adopting the use of thermal mass principleas to attain thermal comfort.( red : canva, yellow: open)ROOF PLAN 1-500VEGETATION ARRANGEMENTGreeneries placement is stragetized.One is the acoustic consideration in outdoor . Taller trees areplaced in the reading area of the building. Green pads areplaced on the playground side.Secondly, vegetation helps shading the hall area, which is acomparatively larger space and easy to accumulate heat underhot atmosphere. And putting plants and trees in the corridorcan help cooling the wind.ElectricityStoragefountainwind towerfountainHallwind towerOutdoor Classroomfountainstaff roomwind towerplatformclassroom Aclassroom Cside entrance 1WC FWC Mside entrance 2playgroundplayground with grass pSOLAR RADIATION / AIR TEMPERATURETHERMAL MASSMass is an important vocabulary of the architecture design . Under hot and aridclimate, thick layer of wall partition and evelope can help regulating the temperatureof the interior space.Theoretically, thickness of the thermal mass is not less than 300mm. But theschool here, as located in an open site, mutual shading is less possible. Thus,the envelope contacting to the exterior have 800 mm thick , while the partitionwall have 400 mm thick. To produce such thickness, it is proposed to use in situconcrete with the addition of mud in the concrete mixture, it promotes low costconstruction. Also, insulation is recommended as well.PRODUCED BY AN AUTODESK EDUCATIONAL PRODUCTSECTION 1-200PAINTED WITH LIGHT COLOURPainting the building with light color can effectively reflect the sunlight away. As light colour is a good radiation reflector.GROUND COUPLINGThe ground itself is a good thermal mass to balance the temperatureof the building. Built in a one storey linear shade, the contact area tothe ground is maximized. In saudi arabia , the surface temperatureof the ground is very high, therefore, I have submerged the buildingfor about 2000 maximum to ensure performance.
