Description
Summary:► Six passive roof designs were tested simultaneously outdoors. ► Roof, attic and ceiling temperatures were determined. ► Solar collector roof design provided the coolest attic and ceiling. ► Placing insulation under roof is preferred to above ceiling. High ambient temperatures coupled with high humidity lead to uncomfortable conditions that are non-conducive for human comfort and productivity. Heat transmission through the roof could be reduced by providing insulation in the attic under the roof or above the ceiling. A roof solar collector could provide both ventilation and cooling in the attic. Several laboratory sized units of passive roof designs were constructed and tested side-by-side under outdoor conditions to obtain temperature data of the roof, attic and ceiling in order to compare their performances.
