Conclusion
Presentation Outline Project Background Proposed Mechanical System
Electricity – Northeastern Utilities suppliers provide
Existing Mechanical System electricity rate of 0.09051/kWh to commercial buildings.
•CHP system
Electricity rate =(0.09051/kWh) * (1 kWh / 0.003412 MMBtu)
Proposed Mechanical System •Feasibility Check = $26.53/MMBtu
CHP System •Spark Spread = Electricity rate – Gas rate
Natural gas – Natural gas price was adjusted by the
= $11.29/MMBtu government and it is 14.81 dollar/ 1000 cubic feet.
GSHP System Natural gas rate = 14.81 dollar/ 1000 cubic feet *1.029 =
$15.24/ MMBtu
Acoustical Breadth •System may be inefficient
Spark Spread = electricity rate – natural gas rate
Cost Estimation •Spark Spread was lower than $12/MMBtu
=$26.53/ MMBtu – $15.24/ MMBtu = $11.29/ MMBtu
•Building does not run 24/7
