Table 3. Orlando Parametric Simulations
Simulation | Input Deck Changes From Reference Case | Research Question Asked |
1 | 1:150 Attic Ventilation | Effect of increasing attic ventilation area from current Orlando building code |
2 | Sealed Attic, R-19 insulation on flat ceiling | Effect of just sealing attic |
3 | Sealed Attic, R-28 insulation on flat ceiling | Effect of sealing attic and increasing insulation |
4 | Sealed Attic, R-19 insulation under roof slope | Effect of sealing attic and moving insulation under roof slope (air and thermal barrier at roof plane) |
5 | Sealed Attic, R-28 insulation under roof slope | Effect of sealing attic and moving insulation under roof slope and increasing insulation |
6 | White Tile Roof | Effect of white tile roof alone |
7 | Sealed Attic, R-19 insulation under roof slope, White Tile Roof | Effect of sealing attic and moving insulation under roof slope and using white tile on roof |
8 | Sealed Attic, R-28 insulation under roof slope, White Tile Roof | Effect of sealing attic and moving insulation under roof slope and increasing insulation and using white tile on roof |
9 | Ducts In Conditioned Space | Effect of placing ducts inside conditioned space (conduction heat transfer effect only, no duct leakage) |
10 | Duct Leakage, 10% Return Side, 5% Supply Side, (Return leak comes from: 70% attic, 20% garage, 10% outdoors) | Effect of average amount of duct leakage (Based on measurements from 160 Florida homes, the average return side leak was 11% of the total flow, and the estimated average supply side leak was 5% (Cummings 1991)) |
11 | Duct Leakage, 15% Return Side, 10% Supply Side | Effect of greater than average amount of duct leakage |
