Motivation for learning about
Energy Simulation in Building Design
Buildings:• Responsible for ~40% of total energy consumption in U.S.
• Affect the CO2 emission
• Building energy systems with the building envelope affect:• Energy consumption – operation cost
• First cost – capital cost
• Thermal comfort and IAQ
Energy analysis for - Optimum balance between operational and capital cost
