R-Values
 

  • Final U=0.4918 W/m^2*K


Energy Requirements
  • 6162 Heating DD             
  • 1060 Cooling DD




    Final Calculation
    • 167 CFM ventilation rate
    • q required = [UA + mass flow rate(Cp)](degree days) 
    • Heating: 9.5e6 BTU
    • Cooling: 1.6e6 BTU




    HVAC Unit


     SEER = 15, HSPF = 9.5

    TOTAL REQUIRED HEATING/COOLING ELECTRICITY: 1,107 kwh





    Appliances

    • 530 kwh/month =  6360 kwh/year
