Abstract:
Thermal loads have been measured for a sample Hall (1)from Sudan
University of Science and Technology, based on mathematical models and
HAP software.
The measurement was based on comparison when without any thermal
insulation material used in the wall and roof, and use one of material from
three difference of thermal insulation(10cm thickness) in wall and roof
(Extruded polystyrene material, Spray polyurethane material, Air cavity) .
The decremental has been calculated wall load and roof load which led to
decrease in annual operational cost, and results are shown below:
- The first once (without any thermal insulation material), the thermal load
was 166.76Kw.
- The second once (Extruded polystyrene), the difference in thermal load
was 53.9Kw, which led to decrease in annual operational cost with
percentage (32.32%) out of total annual operational cost.
- The third once (Spray polyurethane), the difference in thermal load was
56Kw, which led to decrease in annual operational cost with percentage
(33.58%) out of total annual operational cost.
- The fourth once (Air cavity), the difference in thermal load was 28.24
Kw, which led to decrease in annual operational cost with percentage
(16.99%) out of total annual operational cost.
