  26. ENERGY SAVINGS of Over 15% vs. Forced Air Heating Systems Energy Savings

  27. Cornwall, ON - Residence - AFI 800 @ Design Condition – 10 Btu/hr/ft² =8.3% SAVINGS Energy Savings @ Design Condition

  28. Savings over a Heating Season 3°C Reduction in Indoor Temperature = 18.6% SAVINGS Forced Air LEGALETT Energy Savings – Over the Heating Season

  29. Heat Loss for a Building • Conduction - LEGALETT • Natural Infiltration - 0.12 Air Changes per Hour (Equivalent to 1.5 ACH @ 50 Pa) • Ventilation - By Others Heat Loss Calculations

  30. Legalett Engineering Protocols : • Optimal Heater Box Location • Optimal Piping Design Density and Layout • Piping Insulation Placement In-House Engineering Protocols

  31. Temperature and Heat Flux vs Distribution Loop 5” Slab / 2” Pipe system – Project # 6037- SAE 136 House Slab Surface Temperature / Heat Flux along Pipe Loop

  32. Heat Loss through Slab and EPS/Slab Surface Temperatures Computer Simulation Output for Slab and EPS

  33. Structural Design Legalett Foundations are designed by Professional Engineers in accordance with the NBC and IRC Structural Design

  34. EPS • ASTM C-578 • CSA CAN/ULC-S701-01 • Type II – 1.35lb/ft³ (21.6kg/m³) • 15 psi (104 kPa) compressive strength • LEGALETT Design - 50 kPa for long term loads EPS Properties

  35. Soil Loading Design Bearing Capacity 75 kPa vs.150 kPa With the possibility of reducing to 1 7 kPa in problem soils with little change in design Soil Loading

  36. Loads are Analysed Loads are Analyzed

  37. Reinforcing Calculated Reinforcing Determined

  38. Deformations Reviewed and accepted Deformations Reviewed and Accepted

  39. Shear Stress Reviewed and Accepted Shear Stress Reviewed and Accepted
